[adafruit/circuitpython] New comment on issue #368: atmel\-samd: lto\-type\-mismatch and ERROR 1 on build

After cloning repository do you do the following?
git submodule update --init --recursive

then when building it is good to d:
make BOARD=metro_m0_express clean
then
make BOARD=metro_m0_express

Sounds like your toolchain is too old. You can get a newer one by doing this:

sudo add-apt-repository ppa:team-gcc-arm-embedded/ppa
sudo apt update
sudo apt install gcc-arm-embedded python build-essential

Take the old toolchain out of your path.

soooooo

#

Remember when I said I need to spin up a new pi

idle owl Oct 25, 2017, 2:52 AM

#

It wouldn't even let me into the directory in terminal initially. Took a few resets to get it to show up in Finder correctly which while I had no intention of using the explorer to delete the file, it was freezing my terminal when it wasn't working in Finder anyway... reset a few times, took some fussing, but I finally got it to where I could delete it.

@formal plover Oh man...

formal plover Oct 25, 2017, 2:52 AM

took down my network

#

fun fact... when you have 4 usb ports and every since one has a CircuitPython board plugged in...

@formal plover ouch

#

bootloader mode will shut off the pi evey time

umbral dagger Oct 25, 2017, 2:53 AM

#

C-d does not force a reload. But if I press C-d several times (nothign happens) but then I press C-c, for each one a C-d gets processed. Once they're all processed, a C-c gets me to the repl.

#

Something going on with USB input processing?

solar whale Oct 25, 2017, 2:55 AM

#

@formal plover anotehr reason for the 9v supply - is it a powered hub?

#

bee back in 5 - I have to give the cats their treats!

idle owl Oct 25, 2017, 2:55 AM

#

Reset, doesn't mount in the explorer, enter the REPL, it shows up in the explorer. Repeat, mounts the first time. So that's inconsistent. Ahhh... but it won't let me do anything with it in Finder like it did when it had a main.py. This time I enter the REPL and it disappears from Finder. lol. Third and fourth time, like the first.

tyep dmesg - anything of note

#

@tulip sleet sorry about the wrong advice re: -lto error - I keep forgetting that that is the toolset

you folks seem to be willing to take a lot of punishment! I hope (and I'm sure Scott does too) that we'll fix all this in the next few days

solar whale Oct 25, 2017, 3:06 AM

#

probaly similar - 3.0 is not kind to USB

#

@tulip sleet we are gluttons for punishment - all for a good cause.

#

I'm here for the punishment

#

lol

idle owl Oct 25, 2017, 3:07 AM

^^

#

@tulip sleet It's part of any development. The only thing that changes is the flavor.

tulip sleet Oct 25, 2017, 3:08 AM

#

in the meantime it's good jlink practice 😁

formal plover Oct 25, 2017, 3:08 AM

#

So cool to watch it develop

#

and yes good fun with the jlink

idle owl Oct 25, 2017, 3:09 AM

#

Though practice implies some previous knowledge to practice, lol..... all of it feels like brand new fumbling still.

pastel panther Oct 25, 2017, 3:09 AM

#

@tulip sleet is CP close enough in design still to micropython for information on its architecture to be relevant to CP?

solar whale Oct 25, 2017, 3:09 AM

#

@pastel panther my metro-wing boards are in fab! Looking forward to trying one!

formal plover Oct 25, 2017, 3:10 AM

#

@pastel panther closest match is the feather HUZZAH

umbral dagger Oct 25, 2017, 3:10 AM

#

@solar whale metro-wing?

pastel panther Oct 25, 2017, 3:10 AM

#

@solar whale sweet! I hope there are no bugs!

tulip sleet Oct 25, 2017, 3:10 AM

#

@pastel panther very much so; the main CPy changes are the atmel-samd port (which didn't exist before) and the changes of how to do I/O.

pastel panther Oct 25, 2017, 3:11 AM

#

@umbral dagger I made an adapter for putting featherwings on a metro/uno

#

@tulip sleet Ok cool. I'm trying to get familiar with the code and an idea of the rough shape would be helpful

formal plover Oct 25, 2017, 3:12 AM

#

I say that because it's maintained more of the MicroPythonish stuff (not by a lot, but more than some other boards)

pastel panther Oct 25, 2017, 3:12 AM

#

I've been able to grok some stuff by reading the code but more info is always better

#

@umbral dagger I can point you towards my oshpark page but I'm hesitant to encourage anyone else to order one until they've been tested

umbral dagger Oct 25, 2017, 3:13 AM

#

@pastel panther Ah. Cool.

tulip sleet Oct 25, 2017, 3:13 AM

#

the Python language implementation is completely the same. The shared-bindings and shared-module structure is new from Scott. It's a regularization and a cleaner split between port-independent and port-dependent parts. (port = chip choice)

pastel panther Oct 25, 2017, 3:13 AM

#

right, makes sense

umbral dagger Oct 25, 2017, 3:13 AM

#

I'm waiting for an order of prototype boards to arrive (Tinket M0 based)

formal plover Oct 25, 2017, 3:14 AM

#

@tulip sleet always so good at explaining things out

pastel panther Oct 25, 2017, 3:14 AM

#

were those base on the flash upgrade you did?

umbral dagger Oct 25, 2017, 3:16 AM

#

@pastel panther no. This is a small embedded humidity monitor/alarm. TrinketM0 + Si7021 breakout + TPL5110 + piezo buzzer + lipo

umbral dagger Oct 25, 2017, 3:22 AM

#

@pastel panther Though if I do commercialize it, I'll probably do a fully custom board (i.e. no breakouts)

@umbral dagger I'm always looking for excuses to make new boards, hence the metrowing exists

umbral dagger Oct 25, 2017, 3:23 AM

#

@lofty topaz I want a delay on the order of a second. That's a lot of nops.

lofty topaz Oct 25, 2017, 3:24 AM

#

@umbral dagger Sorry, it just popped into my head for some reason. Memories can be a beeech. 😃

umbral dagger Oct 25, 2017, 3:24 AM

#

@pastel panther I'm the same. This board uses the breakouts (& the Trinket) and will be for a small batch of prototypes to actually deploy.

#

@pastel panther You use Oshpark? I have yet to try them. I've used FritzingFab and now Aisler (since they took over as Fritzings fab)

#

Does Oshpark do assembly as well or just raw boards?

pastel panther Oct 25, 2017, 3:27 AM

#

@umbral dagger I've only used them but for the two projects I have, they've been great. They only do boards, though rumor is they're working on a flex-pcb service

I looked at the issue DigitalInOut.c#L65 and it contains the C source code in question. So they will all be like this one. I was given to thinking that it is a broader general problem. But, maybe you are saying that there are clearly defined specifc cases that issues have been noted already by others. Yes, that will be much easier.

[adafruit/circuitpython] New comment on issue #368: atmel\-samd: lto\-type\-mismatch and ERROR 1 on build

I had the same issue on Ubuntu under Windows 10. I can assert that updating the toolchain as dhalbert suggests, followed by the build process that jerryneedell documents, should solve the problem. If the OP (rrace001) can confirm the build process is working I think we can close this.

[adafruit/circuitpython] New comment on issue #360: Aggregate pulse states between all CircuitPython repos\.

To be clear, @tannewt , this is a request for a standalone Python program that you would run, for example, on your laptop, which would interact with the GitHub API to extract and aggregate the desired stats? I am stating it this way because I don't see a way to do this using Pulse within GitHub itself. Perhaps I'm just not familiar enough with it, though.

@tulip sleet a breakpoint() function... it's Smalltalk in 1980 all over again! In that case it was a halt method.

formal plover Oct 25, 2017, 1:10 PM

#

@stuck elbow both I guess.

tulip sleet Oct 25, 2017, 1:10 PM

#

@umbral dagger limor was interested in this. I was looking at what's coming up in Python 3.7. I was actually writing Smalltalk code in 1980.

stuck elbow Oct 25, 2017, 1:11 PM

#

because I'm not really impressed by JLinkExe

umbral dagger Oct 25, 2017, 1:12 PM

#

@tulip sleet sweet, Smalltalk was my first exposure to OO. Worked in it my first couple jobs out of grad school (and my grad work implementations primarily were in Smalltalk).

tulip sleet Oct 25, 2017, 1:13 PM

#

@umbral dagger me too. I did my thesis work in Smalltalk at Xerox: https://danhalbert.org

umbral dagger Oct 25, 2017, 1:13 PM

#

@tulip sleet As we move to more capable chips, it makes sense to enhance the implementation. Adding a debugger would be a good move.

formal plover Oct 25, 2017, 1:14 PM

#

@stuck elbow Haha I just think it's cool that I can take a dead board and program it with the jlink. So I guess the concept is what I like

umbral dagger Oct 25, 2017, 1:14 PM

#

@tulip sleet Legit background

tulip sleet Oct 25, 2017, 1:15 PM

#

@umbral dagger I'm old

umbral dagger Oct 25, 2017, 1:15 PM

#

@tulip sleet Some of us are.

stuck elbow Oct 25, 2017, 1:15 PM

#

@formal plover I see, well, I'm quite used to microcontrollers that you can't brick. STM32s even have a serial bootloader built-in, so you don't even need a special programmer

formal plover Oct 25, 2017, 1:16 PM

#

@tulip sleet has a very awesome/impressive background

#

He's the real deal.

drowsy geyser Oct 25, 2017, 1:23 PM

#

Ok, enough playing around. 😃 Time to put away Atmel Studio and actually get ready for work. I'll be AFK for a bit but I should be back online within the hour. I'm looking forward to the day's developments!

umbral dagger Oct 25, 2017, 1:31 PM

#

@tulip sleet Back to CP... based on what I was seeign last night, I am wondering if there's a race condition with USB initialization and running main.py (or one of the other 3 options).

#

@tulip sleet Things run fine if there's no code to execute. I.e. screen connects and I'm in the repl. Add a code file then and all remains good.

#

@tulip sleet If there's a code file to start, screen just gives nothing. Remove the code file and boom you're in the repl.

tulip sleet Oct 25, 2017, 1:32 PM

#

@umbral dagger you mean in 3.0? I'll look at that: it could easily be true. But on Linux, it's messed up even without main.py.

umbral dagger Oct 25, 2017, 1:33 PM

#

3.0, latest (as of ~11:00pm ET) master. on Linux.

#

@tulip sleet With the patch you posted to only start one device.

tulip sleet Oct 25, 2017, 1:35 PM

#

@umbral dagger - hmm - I'll erase my flash to make sure there's no main.py. Maybe just try a delay as well. Do you see stuff in syslog restarting every 30 seconds without main.py? That's what I was seeing.

drowsy geyser Oct 25, 2017, 1:38 PM

#

@umbral dagger Does the default build include main.py? My board is not working so I can't check atm. I have a fresh compile and it neither gives me a REPL nor mounts CPYTHON.

umbral dagger Oct 25, 2017, 1:38 PM

#

@tulip sleet I do.. approximately every 30 sec.

#

@tulip sleet And CIRCUITPY doesn't show up

tulip sleet Oct 25, 2017, 1:39 PM

#

@umbral dagger same here I am planning to look very carefully at the ASF4 library this morning and how we are calling it.

floral dagger Oct 25, 2017, 1:40 PM

#

lol @formal plover I know what you mean. I usually keep up with what's going on in here pretty well. Then, sometime around midday, it gets really busy, and it's like you're all speaking a foreign language lol.

umbral dagger Oct 25, 2017, 1:41 PM

#

@tulip sleet OK.. several resets & dis/re-connection usb CIRCUITPY shows up and I can get the repl.

drowsy geyser Oct 25, 2017, 1:41 PM

#

@umbral dagger You and @tulip sleet are using Linux?

tulip sleet Oct 25, 2017, 1:41 PM

#

@drowsy geyser yes

formal plover Oct 25, 2017, 1:42 PM

#

@floral dagger Haha right?! Or morning nothing works, then I check after work and @tulip sleet and @slender iron are on version 5.0 and 3.0 is sooo this morning. Lol

#

An exaggeration of course lol. But you get the point

umbral dagger Oct 25, 2017, 1:42 PM

#

@tulip sleet Really smells like something in USB setup. The semi-nondeterminism makes me think race condition of some sort. Especially where that's happened elsewhere. And the fact that it's running ~3x faster than previous hardware.

drowsy geyser Oct 25, 2017, 1:42 PM

#

Interesting. No amount of resetting/reconnecting will get it to work on Windows 10. I'll have a Linux desktop tomorrow night to experiment with.

umbral dagger Oct 25, 2017, 1:43 PM

#

Different systems -> different USB stacks -> different timings -> different behaviour.

#

@drowsy geyser Linux, yes.

drowsy geyser Oct 25, 2017, 1:45 PM

#

Thanks!

umbral dagger Oct 25, 2017, 1:45 PM

#

Also, once I get to the repl, it seems pretty solid.

tulip sleet Oct 25, 2017, 1:47 PM

#

@umbral dagger I am having the same problem on M0's. I haven't bothered to try on M4 yet. The devices are recognized properly by Linux if you look in the system log. But the issues with connecting to the REPL could be a race condition on the CPy side. THe "every 30 seconds" thing is odd, but the device is not talking to the host regularly, as it does in CPy 2.x (based on USb traces). ... Try letting it sit for several minutes with not activity and see if the REPL disconnects.

umbral dagger Oct 25, 2017, 1:49 PM

#

AH.. ok. maybe not that. Or maybe since using the ASF code is a 3.0 addition, yes?

#

@tulip sleet leaving it sit in the repl and tailing syslog

tulip sleet Oct 25, 2017, 1:51 PM

#

We switched from ASF3 to ASF4, which is a completely different set of libraries. It's also new and poorly documented. Scott had to write a scraper from the http://start.atmel.com website to get the code bundle: it's not even available as an ordinary packaged download, and there's no version information (can't tell when they update it).

#

There is no ASF3 for SAMD51, or else we would have just continued with that.

umbral dagger Oct 25, 2017, 1:52 PM

#

@tulip sleet ugh

drowsy geyser Oct 25, 2017, 1:52 PM

#

Slight update: on Windows 10 pressing reset does nothing to make CIRCUITPY appear or the repl work. Disconnecting and reconnecting, however, does make CIRCUITPY mount. As soon as I try writing a file to the device, though, it locks up, the write never completes, and the REPL is not available. Again, the reset button does nothing and it takes a power cycle/disconnect-reconnect to bring it back.

#

And the write worked , in that my code.py now runs, but it never "completed" from the OS perspective.

umbral dagger Oct 25, 2017, 1:54 PM

#

@tulip sleet 5 minutes and repl is still good and no USB related activity in syslog

formal plover Oct 25, 2017, 1:56 PM

#

@tulip sleet is 3.0 going to use ASF4 for all the boards, or just SAMD51 boards?

tulip sleet Oct 25, 2017, 1:57 PM

#

@umbral dagger so the 30 second thing is something where the mass storage is cycling state for some reason.

#

ASF4 for all - it's too much trouble to have separate impls. If we can get it working on SAMD51 it should work fine on SAMD21 and vice versa. The differences are slight.

formal plover Oct 25, 2017, 2:02 PM

#

@tulip sleet Gotcha. I figured as much

#

Once you guys get it stable, it won't be as painful I'm sure

#

Says the guy not directly working on core code

#

Hahaha

umbral dagger Oct 25, 2017, 2:07 PM

#

OK.. back to Haskell for me. I'm around and this will be open if anything needs testing on linux. Just yell.

formal plover Oct 25, 2017, 2:09 PM

#

Sounds good @umbral dagger. I'm on break right now, but I'll check in at my 2pm break to see if the Linux status has changed.

drowsy geyser Oct 25, 2017, 2:17 PM

#

@umbral dagger Haskell? Wow. The quintessential functional language, and Python. Almost polar opposites (though functions are first class objects in Python, too).

umbral dagger Oct 25, 2017, 2:20 PM

#

@drowsy geyser There are overlaps. The typing in Haskell was annoying at first, but I'm growing to love it. I spend most of my "free" time working in Lisp (Scheme actually), and various things for work. At the moment I'm adding some property based http API testing and decided to use QuickCheck. Now I'm refreshing/expanding my understanding of Haskell.

drowsy geyser Oct 25, 2017, 2:20 PM

#

Nice!!!

#

is impressed

umbral dagger Oct 25, 2017, 2:21 PM

#

@drowsy geyser You'll see me react at times with "don't use strings for that!" It seems to be a knee-jerk reaction now. "But.. but.. there's no type information on a string!"

#

@drowsy geyser Actually some things at work are getting more functional: ObjC -> Swift, Java -> Kotlin. The .Net folks are resolute in their love of C#. I'll be gently nudging them toward F# in time, but there's many of them. Also, we have several ex-MS people, so it's deeply engrained.

drowsy geyser Oct 25, 2017, 2:25 PM

#

@umbral dagger I hear you on the C# camp (I work at Microsoft). But there are things that are forcing their hands. For example, HDInsights (aka Spark 😃 ) is really most effective with Scala - which I'm teaching myself since I've been offered a 1,000 core cluster for experimenting.

umbral dagger Oct 25, 2017, 2:26 PM

#

@drowsy geyser Nice. Scala is certainly popular. Especially with the data commuinty. It's popular and high paying on the FP job boards, as well.

drowsy geyser Oct 25, 2017, 2:28 PM

#

I'm still wrapping my head around functional programming. Just like people will look at my code and suggest more pythonic approaches ("you really should use a list comprehension there"), people will look at my Scala code and say my imperative programming background is showing. 😃

fringe trench Oct 25, 2017, 2:29 PM

#

@drowsy geyser Just remember not to have side effects!

#

heh.

drowsy geyser Oct 25, 2017, 2:29 PM

#

Much easier said than done! At least for me....

fringe trench Oct 25, 2017, 2:30 PM

#

If you can think back to math classes in college, that's what helps me.

#

But, I'm mostly a Python coder.

umbral dagger Oct 25, 2017, 2:30 PM

#

@drowsy geyser That's why I like Haskell... stricter. IMO a better place to learn FP.

fringe trench Oct 25, 2017, 2:30 PM

#

Haskell is a pure-functional language.

#

Which is why there are some weird things to do normal stuff you might want to do, like print things, that change the state of the world.

drowsy geyser Oct 25, 2017, 2:31 PM

#

I'm mostly a security architect, but I dabble in coding, mostly Python and R, but now Scala. Maybe I should study Haskell in the evenings to sort of force my hand at FP....

fringe trench Oct 25, 2017, 2:32 PM

#

Haskell is also a lazy-evaluation language, which lets you get away with apparently infinite loops.

#

Like defining the infinite sequence of counting numbers. It won't calculate any of them until you try to do something that actually requires a value.

#

Then it will calculate as many as you use, as you use them.

drowsy geyser Oct 25, 2017, 2:33 PM

#

That's kind of interesting. I can see where that would be very useful in set theory.

fringe trench Oct 25, 2017, 2:34 PM

#

Some of the Haskell libraries are built by people with a lot of interest in category theory.

#

Enough so that one of my friends joined a reading group to get a handle on Homotopy Type Theory.

#

Which I don't understand, so don't ask. 😃

drowsy geyser Oct 25, 2017, 2:35 PM

#

That's serious. 😃

umbral dagger Oct 25, 2017, 2:35 PM

#

Clojure is similarly lazy

fringe trench Oct 25, 2017, 2:35 PM

#

My sense is that Clojure is very Lisp-y

umbral dagger Oct 25, 2017, 2:35 PM

#

And you can easily implement lazy sequences in Scheme/Lisp

#

Clojure is a Lisp syntactically

#

It's somewhat something else really though

fringe trench Oct 25, 2017, 2:36 PM

#

@umbral dagger function arguments are lazy in Haskell also.

#

It's lazy in general.

#

But, strongly typed, with decent type inference.

umbral dagger Oct 25, 2017, 2:37 PM

#

@fringe trench You mean function ARGUMENT (singular) 😃

fringe trench Oct 25, 2017, 2:37 PM

#

autocurrying is a thing also, yes.

umbral dagger Oct 25, 2017, 2:37 PM

#

@fringe trench multi-argument functions are really just curried single argument functions

#

@fringe trench but not in a hurry... lazily 😃

fringe trench Oct 25, 2017, 2:39 PM

#

thunk thunk thunk.

#

Anyway, I'm not any good at Haskell.

#

I just think it looks cool.

#

I've done Hello World in a number of languages, just so I have references.

drowsy geyser Oct 25, 2017, 2:40 PM

#

So, if the argument is lazy, does that mean the compiler (interpreter?) doesn't allocate memory for the data until they're referenced?

umbral dagger Oct 25, 2017, 2:41 PM

#

@tulip sleet from my poking around last night it looks like maybe_run is the entry point into the python VM. Yes? so one could replace the python vm (and a corresponding stuff around calling maybe_run) and get all the other goodness? repl command line editing, USB storage file system, etc? There's need to be changes to repl details, naturally.

#

@tulip sleet I'm just wondering how decoupled that is.

#

@tulip sleet See, I have this Scheme runtime in C that I've been working on with the idea of running it in an embedded environment...

#

@drowsy geyser Nothing gets evaluated until its value is requested.

drowsy geyser Oct 25, 2017, 2:43 PM

#

Cool!

umbral dagger Oct 25, 2017, 2:44 PM

#

@drowsy geyser Hence, if you have an infinite sequence, and ask for the first 5, it computes the first 5 values in the sequence. You can later ask for more values from it, and it will compute them then.

tulip sleet Oct 25, 2017, 2:46 PM

#

@astels well, maybe, but the python object types are used all over the place. So for instance the stuff in shared-bindings is the python-to-hal interface, but sometimes the objects are passed down into the hal level. You could probably use the top level stuff around main.c, but there's not a lot of it.

fringe trench Oct 25, 2017, 2:46 PM

#

@drowsy geyser I don't know.

tulip sleet Oct 25, 2017, 2:46 PM

#

there was no attempt to decouple python knowledge at the various levels

fringe trench Oct 25, 2017, 2:47 PM

#

@umbral dagger you could maybe port it as an IPython kernel, and interact with it in Jupyter notebooks....

#

Here's the Hello World repo in case anyone's interested: https://github.com/pcurry/hello-hello

GitHub

pcurry/hello-hello

hello-hello - How many languages can I greet the world in?

umbral dagger Oct 25, 2017, 2:51 PM

#

@tulip sleet makes sense. The USB storage and change detection, and USB repl are the especially interesting bits.

tulip sleet Oct 25, 2017, 2:52 PM

#

@umbral dagger yes, the lowest level stuff that talks to the HW libraries could be reused, and the FAT storage stuff, which was adapted from an existing library.

#

The change detection has its own issues, due to delayed write of metadata both in Windows and Linux.

umbral dagger Oct 25, 2017, 2:58 PM

#

@tulip sleet OK, sounds like I could reuse enough to be worthwhile. If I ever get back to that project. It's close.. just have to finish the gc.

#

@bronze geyser yes. in general, you can use any text editor.

bronze geyser Oct 25, 2017, 3:58 PM

#

Thanks @tidal kiln I guess I'm being stupid. I keep thinking I need a REPL interface to interact with Python on the Huzzah...at the least be able to "mount" a drive like I can on the raspberry pi.

frail geode Oct 25, 2017, 3:58 PM

#

thanks @solar whale and folks

solar whale Oct 25, 2017, 3:59 PM

#

It was nice to find taht we culd upload the bootloader with just JLinkEXE (aka Jlink Commander) - It can also be done with JLinkGDBServer or Ozone. Choose your weapon....

tidal kiln Oct 25, 2017, 3:59 PM

#

@bronze geyser using the REPL isn't required, it's just another way to interact with Python running on the board. in that case (accessing REPL) you would use some form of terminal program

bronze geyser Oct 25, 2017, 4:00 PM

#

@tidal kiln = yah, if I wanna REPL, I use CoolTerm and all is great.

tidal kiln Oct 25, 2017, 4:00 PM

#

@bronze geyser the other way is to just edit a text file and put it on the board, it will then run it for you automatically

solar whale Oct 25, 2017, 4:00 PM

#

@bronze geyser there is no USB like file system on the Feather Huzzah for CircuitPythion

bronze geyser Oct 25, 2017, 4:01 PM

#

Thank you @solar whale. How do I save a file I'm editing in Atom (and then run it)?

#

ah. Right. there was some apy tool or something...thank you.

solar whale Oct 25, 2017, 4:02 PM

#

@bronze geyser you have to upload it via the ampy tool - or WebREPL if you have that working.

#

ampy is the best way in my opinion.

bronze geyser Oct 25, 2017, 4:02 PM

#

ah yes @solar whale . Thank you very much. Thank you @tidal kiln.

tidal kiln Oct 25, 2017, 4:02 PM

#

thanks @solar whale , yeah, the huzzah is a little different

solar whale Oct 25, 2017, 4:02 PM

#

a little 😉

tidal kiln Oct 25, 2017, 4:03 PM

#

didn't read past 'feather'

bronze geyser Oct 25, 2017, 4:03 PM

#

Another challenge I have with the Huzzah is lack of external antenna (i.e. : no FCC/CE certification...so no offering.)

tidal kiln Oct 25, 2017, 4:04 PM

#

that should be on the module itself

solar whale Oct 25, 2017, 4:05 PM

#

@bronze geyser one warnigt - make sure you exit your terminall session to the Huzzah before trying to use ampy to load. Only one serial connection at a time....

@solar whale Oh. Right. makes sense. Thank you.

I am using a Arduino SPI library that talks to an ATM90e26 (energy monitor - reads power, voltage and stuff with input being a current transformer). I'm using it to monitor my house's energy use.

arduino core is 'pretty much done' and we appreciate any bug reports on that too - USB host and I2S dont work but honestly, they didn't work great on SAMD21 either 😄

@meager fog is there a linux build of the updated bossac that can be added to the released builds?

meager fog Oct 25, 2017, 4:25 PM

#

not at this time because i dont have access to a linux box 😃 if you do, give me the bin and ill attach it

solar whale Oct 25, 2017, 4:25 PM

I'll make one toninght when I get home and pass it along. - it is from the arduino branch, correct?

@meager fog I can try Arduino on it as well. Until CircuitPython Linux issues are sorted out.

@slender iron here is someone else trying to use ASF4 and MSC. Very helpful. I also was wondering about MODE SENSE. https://hackaday.io/project/20772-orthrus/log/68209-firmware-success. I'll see if I can find his code.

Firmware success | Details | Hackaday.io

I got Orthrus v3 hardware working all the way as a disk drive last night. There are a few bugs in Start's code that you have to work around:Start doesn't adjust the UTMI_CKTRIM register when configured with a 16 MHx crystal. You have to do that yourself.mscdf.c has no support for the MODE_SENSE_6 command, which is necessary (you just have to give back 4 zero bytes).mscdf.c has a bug where it returns non-zero when there's no error sending the zero-length "sync" at the end of a write.Start doesn't allow you to configure 512 byte endpoints, as the HS spec requires.There are still a couple of bugs to work out - mostly centered around the handling of situations where cards are removed or missing.Performance is not as good as hoped. Throughput is around 540 MB/sec. Halving the SD card clock doesn't appreciably change throughput, so this may be being limited by USB. But even at only ~5 times faster than before, it's now actually usable as opposed to unacceptable.Another couple of days to polish the firmware, and I think I'll be able to send some units off to the HP judges!

is macos finder complaining about data loss a known UF2 thing? like when dragging a UF2 file over.

#

seems like something i remember seeing mentioned before. maybe?

slender iron Oct 25, 2017, 5:12 PM

#

it complains about the early eject

#

the uf2 bootloader is smart enough to know when it has everything it needs

tidal kiln Oct 25, 2017, 5:31 PM

The Finder can't complete the operation because some data in the "FileName.UF2" can't be read or written. (error Code - 36)

that's it. expected / ignore?

@tulip sleet @slender iron regarding Orthus, I actually know the guy who wrote it from my first job, though I doubt he remembers me

@pastel panther he fixed about five bugs in the ASF4 MSC impl; he clearly knows that low-level stuff; I'm trying his patches right now. you can tell me more in DM if you'd rather it be private (e.g. company, etc.)

what do you all think about bring the xtensa toolchain in as a submodule?

solar whale Oct 25, 2017, 6:17 PM

#

@slender iron doesn't the xtensa toochain require a "case-sesnsitve FS on a Mac" - will this cause problems for people who clone the repo?

slender iron Oct 25, 2017, 6:18 PM

#

looks like we could split the travis build using env variables: https://docs.travis-ci.com/user/customizing-the-build/#Build-Matrix

tulip sleet Oct 25, 2017, 6:20 PM

#

you mean https://github.com/pfalcon/esp-open-sdk, and stick it under esp8266 ? There's still a lot of setup needed, but it would make it easier to keep up to date. But maybe just a README in there would be good. I'm wondering if there would be platform issues (one commit works on Linux, another is needed for Mac, etc.)

slender iron Oct 25, 2017, 6:21 PM

#

yeah, thats what I'm thinking

#

more as a way to get travis building the esp8266 builds too

solar whale Oct 25, 2017, 6:22 PM

#

@slender iron the reason I do my esp8266 build in a Vagrant VM is to avoid the case senitive FS for the xtensa.

slender iron Oct 25, 2017, 6:22 PM

#

yeah, I have a sparsebundle FS on my mac for it

solar whale Oct 25, 2017, 6:23 PM

#

do you just have to put xtensa in it ? or the whole CP repo?

tulip sleet Oct 25, 2017, 6:24 PM

#

but you'd have to build the toolchain on each travis run, no? Or we need to pre-build it and stick that somewhere.

@slender iron diff topic: I built a windows mpy-cross last night and passed it to her. I suggested and she liked adding some precompiled mpy-cross's to the release dir now. There'll be pointers in a Learn Guide. I have windows, mac, and 64-bit linux right now. Could build rpi and 32-bit linux later.

#

any qualms?

slender iron Oct 25, 2017, 6:29 PM

#

@formal plover might be better for rpi since he does his dev on one

tulip sleet Oct 25, 2017, 6:30 PM

#

yah, we can just ask someone. I was going to spin up one of my rpi's

slender iron Oct 25, 2017, 6:30 PM

and precompiled mpy-crosses are fine with me

formal plover Oct 25, 2017, 6:30 PM

#

@slender iron what am I doing? Lol

tulip sleet Oct 25, 2017, 6:31 PM

#

we just had a discussion: I am under the impression that the MPy compiler reads the entire source file into RAM without stripping comments or anything in advance. Do you happen to know? I can look it up.

#

@formal plover do you have a built rpi mpy-cross you can drop here? Also @solar whale might have one. We are collecting a set to include with the release

slender iron Oct 25, 2017, 6:32 PM

#

@tulip sleet I don't think it does because the lexer does the reading

tulip sleet Oct 25, 2017, 6:32 PM

#

maybe that used to be true

slender iron Oct 25, 2017, 6:32 PM

when I looked into it before I believe the memory peak was when converting the ASTish thing to byte code

#

I dont have one now, but I can make one if needed.

tulip sleet Oct 25, 2017, 6:32 PM

mac folks - if i have an mpy-cross that is built on high sierra is it likely to be able to run on earlier versions? It's just an executable, but it may have some external dependencies, I guess (the equivalent of .so)

it is easy - just cd into mpy-cross subdirectory and type make.

@tulip sleet @slender iron From a small bit of code spelunking it appears that python source is compiled to bytecode. That happens with all code I assume. The bytecode is stored in, and excuted from, RAM. I'm guessing that MPY files are precompiled bytecode. Does that get copied to RAM before execution or is it executed directly from FLASH?

sick creek Oct 25, 2017, 7:15 PM

#

@split ocean try first with 2 fidget spinners perhaps if you can make them rotate different direction with circuitpython code and iterate from there

tulip sleet Oct 25, 2017, 7:16 PM

#

@umbral dagger .mpy files are loaded into RAM. Only bytecode that is built into the firmware image ("internal frozen modules") can be executed from flash. So importing a .mpy saves a compilation step, but does not save any RAM during executiong.

umbral dagger Oct 25, 2017, 7:22 PM

#

@tulip sleet Thanks. That gives me a couple intersting things to look in to (this stuff is where I live 😃 ) Related: With growing Flash space has thought been given to freezing more modules?

tulip sleet Oct 25, 2017, 7:24 PM

#

@umbral dagger yup right now there are only internal frozen modules in CPX, but we can add more. In the small M0 builds there is still not enough room for anything, and we have more C stuff we want to add (framebuf, turn some features back on, etc.). On the Express boards, we can freeze more stuff. Advantage is saving RAM; disadvantage is keeping them up to date and explaing to people about sys.path and how to make sure the internal frozen ones are imported rather than those in lib/

umbral dagger Oct 25, 2017, 7:29 PM

#

@tulip sleet That all makes sense. Flash grows faster than ram as you move to bigger chips. And you have the option of SPI flash as well (that must slow things down significantly, though... ya? Or is flash slow enough that SPI latency doesn't impact much? Not something I've spent time exploring.)

tulip sleet Oct 25, 2017, 7:35 PM

#

@umbral dagger you can't execute from SPI flash unless you enable XIP (execute in place), and have a 4-bit (QSPI) SPI flash chip interface. Then the external flash can be mapped into the CPU's address space. That's on the SAMD51 but not the 21. The SPI flash chips we're using are single-bit.

FYI: James' book on TDD for embedded C is good. Google did some amazing things TDD related for C++ using macros & templates. Mindboggling cool stuff. I think all that has been opensourced.

@slender iron question if you're free 🙋

@tidal kiln he said he was getting lunch

#

what's maxiumum possible SPI clock on the samd21? I got as high as 24MHz, can I go higher?

#

I can't find it in the datasheet

#

and the code for _sercom_get_sync_baud_val is a bit convoluted

tulip sleet Oct 25, 2017, 8:34 PM

#

@stuck elbow check the first part of this out: https://github.com/arduino/ArduinoCore-samd/issues/147 it says 12 MHz (!)

GitHub

SPI library does not limit the maximum SPI clock frequency as per the datasheet · Issue #147 · arduino/ArduinoCore-samd

While the current SPI.h tries to safe-limit the maximum SPI clock frequency of the SAMD core, it does so in a weird way, assuming F_CPU to be always 48000000L and only for the SAMD21G18A part.

that is weird, I have it working with baudrate=24000000 on my display right now

slender iron Oct 25, 2017, 8:41 PM

#

@stuck elbow I thought 12mhz as well

#

@umbral dagger I was at google for six years so my affinity for testing comes from there

#

@tidal kiln whats up?

tidal kiln Oct 25, 2017, 8:42 PM

#

using tuple to specify channels for differential adc

umbral dagger Oct 25, 2017, 8:42 PM

#

@slender iron Nice. I was with the Test Mercenaries, part of the Testing Grouplet, and edited Testing on the Toilet for a while.

tidal kiln Oct 25, 2017, 8:42 PM

#

tidal kiln Oct 25, 2017, 8:43 PM

#

guess you would like similar syntax for single ended?

slender iron Oct 25, 2017, 8:43 PM

#

haha, ok

tidal kiln Oct 25, 2017, 8:43 PM

#

chan0 = adc[0]

slender iron Oct 25, 2017, 8:44 PM

#

I'd only do a tuple for differential

#

nah, just the int

#

adc[0]

#

👍

tidal kiln Oct 25, 2017, 8:44 PM

#

ok. good.

#

it's also pretty failsafe

#

one element tuples are a little weird

#

(0,) not (0)

slender iron Oct 25, 2017, 8:45 PM

#

exactly

tidal kiln Oct 25, 2017, 8:45 PM

#

but (0) is just 0 so if someone tries it, it will work

slender iron Oct 25, 2017, 8:45 PM

#

yup yup

tidal kiln Oct 25, 2017, 8:46 PM

#

next question is what error to throw

#

i'm using a dict to map the tuple request to actual adc channel

slender iron Oct 25, 2017, 8:47 PM

#

IndexError I believe

#

or KeyError

tidal kiln Oct 25, 2017, 8:47 PM

#

so easiest would be to just let it do the work, which would be a KeyError

#

yep. KeyError

#

you don't want me to trap that and throw something else?

stuck elbow Oct 25, 2017, 8:48 PM

#

@tulip sleet well, 48MHz works in circuitpython, though I have no idea what SPI clock it results in actually — looking at the display's refresh speed, it seems to be less than 48MHz

@tidal kiln Are (0,1) etc. addresses or something?

tidal kiln Oct 25, 2017, 8:58 PM

#

keys

idle owl Oct 25, 2017, 8:59 PM

#

ah

tidal kiln Oct 25, 2017, 8:59 PM

#

basic dictionary semantics:

dictionary = { key : value }

#

and you can have as many key/value pairs as you want

idle owl Oct 25, 2017, 8:59 PM

#

nice

tidal kiln Oct 25, 2017, 8:59 PM

#

and...the best part.....they can be anything

idle owl Oct 25, 2017, 8:59 PM

#

So it's arbitrary?

tidal kiln Oct 25, 2017, 9:00 PM

#

pretty much

#

the most obvious is for the key to be something simple, like an int

#

but doesn't have to be

#

what i linked uses tuples for the key

#

oh, and to get an item, you use:

dictionary[key]

formal plover Oct 25, 2017, 9:02 PM

@tidal kiln @idle owl Re: dictionary keys. Yes, they can be anything, but the implementation has optimizations for numbers and strings. In your case the keys are 2-tuples of small numbers so it's still fast/simple: hash each element of the tuple and add them. Using more complex structures as keys gets more expensive.

tidal kiln Oct 25, 2017, 9:46 PM

#

yep. nothing comes for free.

umbral dagger Oct 25, 2017, 9:47 PM

#

@tidal kiln @idle owl Another thing about dictionaries, and probably more relevant in small memory environments is that can take up significantly more room that what they contain, and they grow non-linearly to maintain a certain overhead as you add to them. They do this to try to maintain a high lookup speed. You're trading space for time. If you're not familiar with the implementation it could be a surprize.

#

@tidal kiln @idle owl In this case you only have a few things in it, and it doesn't grow over time, so it' doesn't have much impact.

tidal kiln Oct 25, 2017, 9:50 PM

#

if there's a more efficient approach, please let me know

#

efficient, but still has user friendly syntax

umbral dagger Oct 25, 2017, 9:51 PM

#

@tidal kiln In this case you're fine: small and simple -> little overhead and cheap hashing.

#

py/map.c and py/objdict.c is the relevant implementation

tidal kiln Oct 25, 2017, 9:52 PM

#

but even there. i'm always amazed at how there always seems to be a better way for everything.

#

at which point someone points out some python feature i've never seen before

cunning crypt Oct 25, 2017, 9:53 PM

#

@tidal kiln That's... pretty much all of my projects, ever. After I'm done, "Have you tried X?" "Huh, that would have saved me a lot of time before!"

umbral dagger Oct 25, 2017, 9:53 PM

#

@tidal kiln You'll often find that it's a trade off between readability/understandability/maintainability and efficiency. Always default to the former. Optimize to something more efficient (and again time/space is then often a tradeoff) only when you have a proven, observable need to.

tidal kiln Oct 25, 2017, 9:54 PM

#

yep. that's inline with my approach.

#

although for embedded stuff, the later can sometimes be the driver.

umbral dagger Oct 25, 2017, 9:55 PM

#

@tidal kiln And if you do optimize and have something less understandable, document/comment the *&^$#) out of it.

tidal kiln Oct 25, 2017, 9:55 PM

#

of course. i always document. 🙄

umbral dagger Oct 25, 2017, 9:56 PM

#

@tidal kiln Yes, embedded has a different set of constraints.

tidal kiln Oct 25, 2017, 9:57 PM

#

yep. and cp is interesting as both are drivers.

#

readability (so it's beginner friendly) and efficiency (since we're running on mcu's)

cunning crypt Oct 25, 2017, 9:58 PM

#

If you're running on a non-Express board, you can even get to a point where individual characters can be too much filespace.

umbral dagger Oct 25, 2017, 9:58 PM

#

Definitely. Memory is probably a bigger constraint than time in most cases anyway. And you often also have power consumption to consider.

#

That said, The chip on the M4 is so much more everything that my first computers (ZX81 and then Apple ][+)....

tidal kiln Oct 25, 2017, 10:00 PM

#

avoid big letters, like O and W and try use skinny ones like I

umbral dagger Oct 25, 2017, 10:00 PM

#

The ATMEGA328 is more in line with those machines.

#

@tidal kiln Well, certainly forget using unicode 😃

I'm waiting for someone to write a python minifier

#

then I can safely give up on python and move onto rust or something

pastel panther Oct 25, 2017, 10:02 PM

#

@stuck elbow wouldn't you need a python bytecode minifier?

umbral dagger Oct 25, 2017, 10:02 PM

#

@stuck elbow Well MP/CP is compiled to bytecode on load and you can precompile to mpy files.

pastel panther Oct 25, 2017, 10:02 PM

#

(for memory usage at least)

stuck elbow Oct 25, 2017, 10:02 PM

#

@umbral dagger but all the names are retained

umbral dagger Oct 25, 2017, 10:02 PM

#

@pastel panther I'm not sure (yet) how much the MP compiler optimizes.

stuck elbow Oct 25, 2017, 10:03 PM

#

so shortening function and variable names still gives you gains

umbral dagger Oct 25, 2017, 10:03 PM

#

@stuck elbow Yes, right you are. That should be a simple compiler optimization... that adds complexity and overhead, so many in the py->mpy version.

pastel panther Oct 25, 2017, 10:04 PM

#

It would be interesting to see a color coded or otherwise human decipherable map of memory usage

umbral dagger Oct 25, 2017, 10:04 PM

#

@pastel panther I believe there's a way to get one

#

@pastel panther in the repl

stuck elbow Oct 25, 2017, 10:04 PM

#

@silent radish you can't do that, as some programs would stop working -- namely the ones that use getattr with computed values

#

python is too dynamic for such optimizations

pastel panther Oct 25, 2017, 10:05 PM

#

@umbral dagger I think I mean something like a byte by byte layout of memory, not a usage figure

stuck elbow Oct 25, 2017, 10:05 PM

@pastel panther that's available in micropython

@pastel panther not sure if cp has it

CIRCUITPY mounts....

pastel panther Oct 25, 2017, 10:44 PM

#

@idle owl Did you previously flash something with the segger to get the double tap->METROM4BOOT to work?

idle owl Oct 25, 2017, 10:44 PM

#

@pastel panther Yes. I had to flash the bootloader with the jlink

stuck elbow Oct 25, 2017, 10:44 PM

#

I suppose Ruby is the closest of those

pastel panther Oct 25, 2017, 10:44 PM

#

ok, nvm for me then

idle owl Oct 25, 2017, 10:45 PM

#

Can you load the uf2 bootloader with bossac?

slender iron Oct 25, 2017, 10:45 PM

#

@idle owl yeah, the cdc reliability stuff I added also caused it to infinite loop if a terminal wasn't connected

drowsy geyser Oct 25, 2017, 10:45 PM

#

@slender iron You're awesome! CIRCUITPy mounts and the REPL works!

slender iron Oct 25, 2017, 10:45 PM

#

@idle owl I have code that will allow you to update the bootloader through bossac

pastel panther Oct 25, 2017, 10:46 PM

#

and bossac doesn't require a jlink?

slender iron Oct 25, 2017, 10:46 PM

#

it'll make it harder to update through jlink later

#

correct @pastel panther

pastel panther Oct 25, 2017, 10:46 PM

#

Ah

idle owl Oct 25, 2017, 10:46 PM

#

Ah ok. That's what I wasn't sure about.

pastel panther Oct 25, 2017, 10:46 PM

#

Maybe I should just wait then

#

@slender iron how much harder are we talking?

slender iron Oct 25, 2017, 10:47 PM

#

@pastel panther it doesn't make it impossible

formal plover Oct 25, 2017, 10:47 PM

#

Oh boy, smoke on mine

slender iron Oct 25, 2017, 10:47 PM

#

with gdb you just have to set a bit to tell it to ignore the bootloader protection

formal plover Oct 25, 2017, 10:48 PM

#

lol jk. Same results as @idle owl using my Pi

idle owl Oct 25, 2017, 10:48 PM

#

lol salty/sassy. @idle owl is correct

slender iron Oct 25, 2017, 10:49 PM

@pastel panther this should update it to the uf2 bootloader. beware it may break things and need a jlink to fix

@slender iron BTW, the problem with history getting garbled is fixed, too. I just tried it again....

slender iron Oct 25, 2017, 10:53 PM

#

@drowsy geyser yeah, my fix for that is what broke mass storage without serial being connected

drowsy geyser Oct 25, 2017, 10:54 PM

Ahhh, ok! Well, all seems to be working now. I'll write some programs to stress test it.

Excellent!

@tulip sleet how closely do you want to review the nrf merge? I just did that usb fix on top of it

#

I could port it back or wait

no USB drives, no screen connection. at the moment I can't get jLink to connect.

bootloader ok?

umbral dagger Oct 25, 2017, 11:00 PM

I dragged your new uf2 to the boot drive

#

@slender iron Ya, this is linux

slender iron Oct 25, 2017, 11:02 PM

#

which uf2 did you grab? circuitpython or the bootloader?

umbral dagger Oct 25, 2017, 11:04 PM

#

@slender iron the firmware.uf2 you posed at 6:40

slender iron Oct 25, 2017, 11:04 PM

#

k, I'll need to test it on linux

#

did you try a different usb port?

tidal kiln Oct 25, 2017, 11:05 PM

could be as simple as...

#

that

formal plover Oct 25, 2017, 11:05 PM

Let me tell you about the wrong usb port...

#

lol

#

For those that were there trying to help me setup the jlink

pastel panther Oct 25, 2017, 11:06 PM

#

That there is such a thing makes me wish they would remove the U from USB

tidal kiln Oct 25, 2017, 11:07 PM

#

i think it might be a software thing too

umbral dagger Oct 25, 2017, 11:07 PM

#

I tried a couple other ports... same

slender iron Oct 25, 2017, 11:07 PM

#

hrm

#

which bootloader do you have?

tidal kiln Oct 25, 2017, 11:08 PM

#

i had my linux box refuse to see my trinket at one point

slender iron Oct 25, 2017, 11:08 PM

#

is it uf2 with neopixel working?

tidal kiln Oct 25, 2017, 11:08 PM

#

while doing a bunch of testing and jumping between arduino and cp

#

tried it on a 2nd linux box and it showed up fine

bootloader timestampsed 10:08 ET last night

slender iron Oct 25, 2017, 11:09 PM

#

and neopixel works?

umbral dagger Oct 25, 2017, 11:09 PM

#

Neopixel seems fine in the bootloader: red than switches to green

slender iron Oct 25, 2017, 11:10 PM

#

kk

#

does it turn off when it should be in circuitpython?

#

(it should)

umbral dagger Oct 25, 2017, 11:10 PM

#

Single reset: yes it turns off

slender iron Oct 25, 2017, 11:11 PM

#

kk, thats when it should be in circuitpython

umbral dagger Oct 25, 2017, 11:12 PM

#

Now, when I hook up the jlink, and double reset, neopixel is red and red LED pulses fast.

slender iron Oct 25, 2017, 11:13 PM

thats when its not enumerated

@umbral dagger thats when you should see the drive and be able to load it

umbral dagger Oct 25, 2017, 11:13 PM

#

Ya... no drive

slender iron Oct 25, 2017, 11:14 PM

umbral dagger Oct 25, 2017, 11:14 PM

#

That's what I'm wondering. BRB going to turn it off and turn it on again

slender iron Oct 25, 2017, 11:14 PM

#

#

now I want to rewatch IT crowd

umbral dagger Oct 25, 2017, 11:15 PM

#

OK.. back

#

plug it in and CIRCUITPY shows up

#

double rest and nothing, and now it's unresponsive again

#

I saw a project really recently to make The Internet

tidal kiln Oct 25, 2017, 11:19 PM

#

did they get approval from "the hawk"?

umbral dagger Oct 25, 2017, 11:20 PM

#

OK.. bounced again. This time I went straight for jlink and reflashed the bootloader.

#

connect USB and have CIRCUITPY, screen in and have the repl

idle owl Oct 25, 2017, 11:20 PM

#

Nice!

umbral dagger Oct 25, 2017, 11:20 PM

#

No for the new firmware.uf2

idle owl Oct 25, 2017, 11:21 PM

#

As in the uf2 didn't work for you?

#

Or you reflashed the bootloader and then it did

umbral dagger Oct 25, 2017, 11:23 PM

#

double reset for the bootloader messes up everything

slender iron Oct 25, 2017, 11:23 PM

#

hrm

umbral dagger Oct 25, 2017, 11:23 PM

#

Nothing works after that.

#

building new bootloader and firmware

#

then bounce and try again

New bootloader flashed, but double reset hoses it

yea, bootloader mode makes it show up but I'm assuming thats bossac compatibily?

it should support bossac and uf2 now

pastel panther Oct 26, 2017, 12:05 AM

I just checked and copying blinky over works

yup, cdc during bootloader is for bossac

pastel panther Oct 26, 2017, 12:07 AM

its serial

#

not sure of the acronym

@solar whale on the RPi, did you build the arm-none toolchain yourself, or did you find a prebuilt version, or did you just use the supplied compiler and it still worked for CPY compiles?

making sure it builds 😃

solar whale Oct 26, 2017, 12:44 AM

#

@tulip sleet been awhile since I built it on RPi - having trouble tonight buildiong bossac so I'm not confident in it - do you have "stretch" installed. I do and that may be part of the problem.

tulip sleet Oct 26, 2017, 12:44 AM

#

@solar whale - no I have ordinary packages and just downloaded the .bz2 from ARM, and will build that, probably.

#

waht raspian vesion are you using jessie or stretch?

tulip sleet Oct 26, 2017, 12:46 AM

#

I am starting with jessie only so I can have an mpy-cross that will definitely run on jessie (and will probably run also on stretch). After I build the mpy-cross I may upgrade to stretch, and rebuild or just test that it works.

formal plover Oct 26, 2017, 12:58 AM

#

I have no idea why, but with no serial connection running at all... just plugged in, not even in bootloader mode. CPU would rise and rise and rise until it locked up

idle owl Oct 26, 2017, 12:58 AM

#

You need to spin up another Pi something fierce.

umbral dagger Oct 26, 2017, 12:58 AM

#

yay @idle owl !! #latetotheparty

idle owl Oct 26, 2017, 12:58 AM

#

@umbral dagger Thanks!

solar whale Oct 26, 2017, 12:58 AM

#

ok - able to build bossac after update - there is hope for arduino! still not sure about CP build - will try that too.

formal plover Oct 26, 2017, 12:58 AM

#

Bwhahahah @idle owl

#

Yeah, gonna do it tomorrow. I'll download a fresh copy of NOOBS tonight though

#

Go team ESP32!

solar whale Oct 26, 2017, 12:59 AM

#

@slender iron thanks for all the updates! will give it a try.

idle owl Oct 26, 2017, 12:59 AM

#

@tulip pebble Welcome team ESP32!

formal plover Oct 26, 2017, 12:59 AM

#

Huh?

tulip pebble Oct 26, 2017, 12:59 AM

#

blinka

formal plover Oct 26, 2017, 1:00 AM

#

CircuitPython is on the ESP32 now?

pastel panther Oct 26, 2017, 1:00 AM

#

@formal plover a bunch a ppl in the live chat were asking about helping with a ESP32 port

tulip pebble Oct 26, 2017, 1:00 AM

#

LOL... Not yet...

idle owl Oct 26, 2017, 1:00 AM

#

@formal plover Nah it's team-getting-it-on-the-ESP32

formal plover Oct 26, 2017, 1:00 AM

#

Gotcha! thanks @pastel panther

slender iron Oct 26, 2017, 1:00 AM

#

quick turn @tulip sleet !

formal plover Oct 26, 2017, 1:00 AM

#

Hhaha @tulip pebble more power to ya!!!

tulip sleet Oct 26, 2017, 1:00 AM

#

@slender iron this code I recognize!

slender iron Oct 26, 2017, 1:01 AM

#

😃

formal plover Oct 26, 2017, 1:01 AM

#

I'm still adjusting

slender iron Oct 26, 2017, 1:01 AM

#

for SCSI reference this PDF is good: https://www.seagate.com/files/staticfiles/support/docs/manual/Interface manuals/100293068j.pdf

#

I was putting up a giant vinal decal and paper flowers on a wall...

tulip sleet Oct 26, 2017, 1:01 AM

#

@slender iron squash and merge for this one?

slender iron Oct 26, 2017, 1:01 AM

#

rebase and merge maybe?

#

up to you

I rebase if the commits make sense and squash if there are commits from feedback

idle owl Oct 26, 2017, 1:02 AM

#

I did git pull on the CP repo and got something that looked like errors, but there were so many updates that the scrollback doesn't have the errors anymore, lol. So no idea what that was.

slender iron Oct 26, 2017, 1:03 AM

#

what does git status say @idle owl ?

idle owl Oct 26, 2017, 1:03 AM

#

On branch master, up to date, a list of untracked files.

slender iron Oct 26, 2017, 1:04 AM

#

ah, the untracked files are probably build directories

#

all of the ports moved into ports

idle owl Oct 26, 2017, 1:04 AM

#

And a bunch of .DS_Store files

#

slaps MacOS around a little

solar whale Oct 26, 2017, 1:05 AM

#

@tulip sleet I am able to build mpy-cross on my RPi

#

what is with the ports subdirectory !!!

slender iron Oct 26, 2017, 1:09 AM

#

upstream reorganized 😃

#

I suggested it a year ago and offered to do the work but they baulked then. Its done now though!

solar whale Oct 26, 2017, 1:10 AM

#

cool!

idle owl Oct 26, 2017, 1:10 AM

#

Are we still making the build in circuitpython/atmel-samd or is it in cp/ports/atmel-samd?

slender iron Oct 26, 2017, 1:10 AM

#

the second one

umbral dagger Oct 26, 2017, 1:11 AM

#

No Adafruit order in the mail today, but a bag of transisters from China.

solar whale Oct 26, 2017, 1:11 AM

#

@tulip sleet but cant build CP - need arm-none toolchain . What are you using?

slender iron Oct 26, 2017, 1:11 AM

#

ok I'm off for a while. I expect those changes improved USB but still needs work

tulip sleet Oct 26, 2017, 1:13 AM

#

@solar whale I haven't tried yet. But can you drop your mpy-cross here? Since it's stretch, I'll try it on jessie. Maybe checkout the 2.1.0 tag for consistency before building.

#

@solar whale I thought you were building circuitpython on the RPi (I thought you must be a very patient person if you were doing that.)

solar whale Oct 26, 2017, 1:15 AM

#

@tulip sleet no - I have used it for arduino but not for CP building - yet

#

just a sec - need to get mpy-cross to this machine

tulip sleet Oct 26, 2017, 1:16 AM

#

I'm building the arm-none toolchain, but it will be a while.

idle owl Oct 26, 2017, 1:16 AM

#

I've only got Pi0Ws... I don't think they can handle this stuff at all. And I keep having to remember that's totally not what you guys are running, because I keep picturing you having all of this stuff running off a tiny PI, an OTG cable and a USB hub... Which is quite wrong.

pastel panther Oct 26, 2017, 1:16 AM

#

I mean that should work, right?

#

If we can get it as easy on a RPi as a mac, that would be sweet

formal plover Oct 26, 2017, 1:17 AM

#

@idle owl I might be able to supply you with a Pi 3

idle owl Oct 26, 2017, 1:17 AM

#

@formal plover Oh man...

formal plover Oct 26, 2017, 1:18 AM

#

@idle owl I've got one that I used for a retropie machine... Let's be honest, I won't be using that any time soon

idle owl Oct 26, 2017, 1:20 AM

#

@formal plover lol. I haven't done any dev with a Pi0W in ages... Picked up the CPX and never looked back. I have a Pi0W running my tabletop lightbox photo studio, so I ssh in, run the last command and it does it's thing. That's all I've done in so long...

solar whale Oct 26, 2017, 1:20 AM

#

@tulip sleet here is my mpy_cross for RaspberryPi Stretch

📎 mpy-cross

formal plover Oct 26, 2017, 1:21 AM

#

I'll reimage it with stretch. You can just VNC into it with your Mac @idle owl

tulip sleet Oct 26, 2017, 1:21 AM

#

@solar whale thanks very much - I'll test and upload it to the release if it works on jessie too.

pastel panther Oct 26, 2017, 1:21 AM

#

@idle owl Your Pi is running a lightbox? Do you have a project page somewhere?

solar whale Oct 26, 2017, 1:21 AM

#

I have only verified that it turns a .py to a .mpy - not that the .mpy runs!

idle owl Oct 26, 2017, 1:21 AM

#

@pastel panther I don't... I keep thinking I should make one but I didn't take any in-progress photos. I made the entire thing.

#

@formal plover I have an DVI to HDMI adapter, an HDMI cable and a wireless keyboard/trackpad combo thing that I was using when I needed display on the Pis. I haven't used it in ages, but it's still sitting there, lol

formal plover Oct 26, 2017, 1:23 AM

#

I also have the one with the Z-wave card on it controlling... a lamp lololol

pastel panther Oct 26, 2017, 1:23 AM

#

beep boop. light on, light off

idle owl Oct 26, 2017, 1:23 AM

#

This is running nearly 2m of 60LED/m dotstars. Obviously the dotstars are powered separately.

formal plover Oct 26, 2017, 1:24 AM

#

Can control like 40 devices.., and I am controlling a singular lamp lol

idle owl Oct 26, 2017, 1:24 AM

#

A friend of mine wrote a quick script to control the brightness and a few different modes, and to control the 3 panels separately. They're soldered into 3 9x9led squares.

pastel panther Oct 26, 2017, 1:25 AM

#

@idle owl if you have any details you can share offline/DM that would be swell. I'm going to be making something similar with UV leds for curing resin to make custom IEMs

idle owl Oct 26, 2017, 1:26 AM

#

@pastel panther Yeah for sure! I'll try to get a few pics this week and I'll write up what I did. Won't be guide-worthy but enough to give you some ideas and at least give you some more questions to ask 😃

pastel panther Oct 26, 2017, 1:26 AM

#

@idle owl awesome, thanks!

#

Anyone know a good place to find a selection of rubber bands? I need to hold a mold together and don't want to wait for the internet

idle owl Oct 26, 2017, 1:27 AM

#

I had it in the works for a while but I ended up finishing it much sooner so I could take the pics for the Key of Lime Learn Guide 😄

pastel panther Oct 26, 2017, 1:27 AM

#

hah, cool

#

Awesome guide btw

idle owl Oct 26, 2017, 1:28 AM

#

Thanks!

pastel panther Oct 26, 2017, 1:28 AM

#

I'm going to try and do it with my neice once I get a CPX

#

the intersection of music and electronics is right up my alley

idle owl Oct 26, 2017, 1:29 AM

That's so great!

What build?

solar whale Oct 26, 2017, 1:30 AM

#

current master - just downloaded and built

umbral dagger Oct 26, 2017, 1:32 AM

#

@solar whale bootloader?

pastel panther Oct 26, 2017, 1:33 AM

#

Did the Makefiles move or am I just...

idle owl Oct 26, 2017, 1:33 AM

#

@solar whale I thought Scott said to run make in the circuitpython/ports/atmel-samd .... Did I misunderrstand?

solar whale Oct 26, 2017, 1:34 AM

#

@idle owl taht is correct

#

@umbral dagger bootlaoder from last night - wioth working neopixel

idle owl Oct 26, 2017, 1:35 AM

#

I just got a boatload of fatal errors.

solar whale Oct 26, 2017, 1:35 AM

#

did you do git submodule update --init --recurstive

umbral dagger Oct 26, 2017, 1:35 AM

#

OK, I have the latest, workign neopixel

idle owl Oct 26, 2017, 1:35 AM

#

not again since I did git pull, I'll try it again

pastel panther Oct 26, 2017, 1:35 AM

#

yea, I'm having to do a submodule fetch

#

much better, building now

umbral dagger Oct 26, 2017, 1:36 AM

#

and it's been sitting here in bootloader mode (looking at the M4.. neopixel green) for 5 minutes or so.. and... the BOOT drive just showed up.

solar whale Oct 26, 2017, 1:36 AM

#

very important - major cahnges - do that at circuitpython/

idle owl Oct 26, 2017, 1:36 AM

#

oh bugger. I did it in ports

#

It seems to be building though

solar whale Oct 26, 2017, 1:36 AM

#

just do it again

idle owl Oct 26, 2017, 1:36 AM

#

After it builds?

#

and then rebuild?

solar whale Oct 26, 2017, 1:37 AM

#

yse - make BOARD=xxx clean then real make
