Ok.
#circuitpython-dev
idle owl
pastel panther
@formal plover not unless someone removed it from my machine ;p
umbral dagger
OK, as before, CP is running fine, CIRCUITPY shows up, I can screen inm but can't get into the repl
solar whale
wow - and it mounts and REPLs on my Mac!
idle owl
@solar whale FYI, I ran git submodule etc again in circuitpython/ and it did nothing. So apparently directory doesn't matter
Rebuilding after clean anyway
pastel panther
@solar whale did you say build in the root directory? There seems to be no Makefile there. ports/atmel-samd built fine though
solar whale
@idle owl good to know
idle owl
@pastel panther Build in ports, correct.
solar whale
@pastel panther build in ports/atmel-samd
pastel panther
@solar whale thats what I though. I guess I was confused by an earlier comment
+t
solar whale
I always do the submodule update at root, but it may not matter
pastel panther
I had to to make my build go after the directory shuffle
idle owl
Mounts immediately, REPL working, blinky flashing.
solar whale
Yay!
umbral dagger
@idle owl You're on Mac?
idle owl
@umbral dagger Yes
pastel panther
hmm, I got mount, blinky but no REPL
unless it's changed names. I'm on a mac fwiw
formal plover
What's displaying for the drive @pastel panther?
idle owl
That's the issue
At least it was still an issue a few hours ago. Something with the way it's handling it, you can't get into the REPL fresh with a code.py running.
Also try /dev/tty.usbmodem* .. I had more than one board plugged in earlier so I had to identify them. I was using the * before that.
formal plover
@pastel panther Ubuntu right?
tulip sleet
@solar whale trying a 2.1 board on Rpi: I don't see a regular ttyACM0 or similar show up. Have you used the REPL from RPi?
solar whale
yes - usually works
formal plover
screen /dev/ttyACM0 115200
pastel panther
@grizzled arch no, mac. No dice after removing any .py from CIRCUITPY and re-flashing
solar whale
just a sec - I'll try my 3.0 on mine
formal plover
ahhhh ok @pastel panther
pastel panther
@formal plover I have no /dev/tty.usb*
idle owl
@pastel panther Hmm.
pastel panther
@idle owl what version of OSX?
formal plover
nvm @pastel panther I thought you were using Ubuntu for some reason
pastel panther
(do you have)
idle owl
Reflashing the CircuitPython firmware won't clear any .py files anyway, at least it's designed not to.
@pastel panther I'm running Sierra
10.12.6 apparently
pastel panther
yea, I know. I just removed it for extra special forsuresies
idle owl
That was a good idea
idle owl
It took some serious nonsense to get the main.py file removed when I tried to do it. Can you remount it a few times and make sure the files are actually gone? Check in terminal...
pastel panther
Also I loaded my bootloader from bossec via instructions from scott, so maybe thats got something to do with it
solar whale
@tulip sleet 3.0 works fin on RPi - mounts CIRCUITPY and REPL ay /dev/ttyACM0
pastel panther
sure, will do
idle owl
Although, eh. no. That shouldn't matter. I could at least get to the serial connection before.
formal plover
@pastel panther ls /dev/tty.*
idle owl
@pastel panther Check it anyway though, it took me a few tries to get the main.py removed, and I wasn't the only one who ran into that.
formal plover
That does a list
tulip sleet
@solar whale for some reason not showing up. Tried two boards, so it's someting else. Maybe a misconfiguration in jessie. or something. I should reboot. I did a huge update after several months of non-reuse
formal plover
and or ls /dev/cu.* @pastel panther
idle owl
@pastel panther Wait does the way you flashed the bootloader affect whether or not you can get a serial connection? You did it differently than we did. I'm starting to speculate here.
pastel panther
@formal plover I think I'm good on locating a serial port if it's there. Thanks though
@tulip sleet would you know the answer to @idle owl's question?
@idle owl @slender iron said it would affect using the jlink but didn't mention anything about the serial port
idle owl
Yeah I remember that but I'm now trying to identify what else is different about your setup that might be causing issues.
pastel panther
though it does do serial port fu to allow bossac to work, so maybe it's related
slender iron
serial support sshould be fine. though I haven't tested on old mac
tulip sleet
i wasn't following the discussion
manic glacierBOT
idle owl
No, it's whether the way they got the bootloader setup could affect whether or not it would be able to get a serial connection. We all used the j-link, @pastel panther didn't.
pastel panther
@tulip sleet the question is if flashing with bossac could cause problems with my serial port(CDC?) not showing up
the wizard says serial support should be fine
slender iron
you have any other computers?
tulip sleet
@pastel panther I don't think so. Did you unplug/replug just to be sure? Which build is this, the aboslute lateest one with the ports/atmel-samd dirs?
idle owl
@pastel panther Also did you try multiple USB ports... so many of us ran into issues there and they were fixed by switching...
pastel panther
@tulip sleet yea, about 5 times or so. I'll check another port
@slender iron no other computer unless I drive to work and dust off my old windows machine
solar whale
@formal plover I was also able to build/load a blinky.ino via arduion to the M4 on my Raspberry Pi! Whew.
pastel panther
awesome @solar whale !
slender iron
np
formal plover
@solar whale YAY!!! Nice! Way to go!
idle owl
@solar whale Nice!
tulip sleet
try a non-usb3 port if you have one, or a hub. But the difference in MacOS versions might be an issue as well. This is with the m4 board? Do you have other boards with CPy 2.1 or 2.0 that work?
solar whale
now to see if I can put CP back on!
tulip sleet
@solar whale - yes, I just needed a reboot
solar whale
great
pastel panther
@tulip sleet I tried both ports, neither work (don't know if one is not USB3 or not). I had blinky/repl working on my metro m0 and feather with 2.1 the other day
I'll have to see if I have a usb port
hub rather
tulip sleet
so just plug in one of the m0 boards and see if ti works, and then we can work forward from that
pastel panther
k
ok, m0 (I think with 2.1) works as expected, repl, blinky, etc
should I try 3.0?
tulip sleet
you could try putting a 3.0 build on one of those boards. You can always put 2.1 back. Just build the right board.
you can use the uf2 loader to load the firmware.uf2
solar whale
whew - taht was odd - when I wen back to linux box with arduino load on M4, I could not get bootloader to mount METROM4Boot - until I rebooted Linux box - then all OK - wa able to reflash CP 3.0 and all happy ...
frail geode
loving the swoopy USB traces on the M4 Metro Express!
pastel panther
@tulip sleet built 3.0 for the m0 express fine, loaded the uf2 fine but now CIRCUITPY won't ls and there is no serial connection
It's hung righ tnow trying to ls
tulip sleet
when did you last pull master?
solar whale
ohman - I missed somethin I have gd613776
pastel panther
d61377 on master, says github
tulip sleet
@solar whale that's what gitlog says?? should be dated 17:41:44 today
idle owl
Oh we're looking at different things. Sorry for confusion.
tulip sleet
@solar whale btw, your mpy-cross works. will upload to release.
solar whale
@tulip sleet that is what th build says - I'm up to date accd to git. - great re:mpy-cross
pastel panther
@idle owl if you type git log|head in your CP directory it should tell you
should be something like ```commit d613776f0d4215e064964c6838de27e81d4fbcca
Author: Scott Shawcroft scott.shawcroft@gmail.com
Date: Wed Oct 25 17:41:44 2017 -0700
atmel-samd: Add support for ERR_ABORTED to indicate medium not present.
yup - same here
idle owl
Oh. Yep, thanks. We were looking at different things, but apparently they use the same number. The REPL shows the beginning of the commit number.
solar whale
@meager fog I was able to get arduino/samd51 working (at least for blink) on a Rasperry Pi as well. A few minor changes to procedure - I will try to post them to the github repo tomorrow after I do a bit more checkout. So far so good on Ubuntu Linux and Raspberry Pi.
formal plover
@solar whale If you switch back to CircuitPython, see if you notice the CPU spike and run high with the M4 plugged in
IF
solar whale
I have it back on my Linux box. just a sec - want to try somthing on RPi any way
formal plover
oh ok, good deal
solar whale
pack on Pi - CPU usage goes up to ~40%
formal plover
It's not just me!!!
Mine went all the way to 80% after like 30mins
Then locked up
idle owl
Interesting
solar whale
I'v got a few thing running - ddi not drop when I went to bootlaoder but now running ad=rduino so hard to tell
formal plover
Yeah, no matter what I had running it continued to rise until I removed it
tulip sleet
High CPU is system-udevd; run top to see what's consuming a lot of CPU.
solar whale
just loked at my linux box and top user is systemd-udevd
tulip sleet
It might be good if someone were willing to write up this stuff. Perhaps someone running linux could open a linux 3.0 issue on things, and someone running on mac could open a similar issue. If you could write down the steps to reproduce and what does and doesn't work, that would be good.
other people could add any variants on the original report
formal plover
@tulip sleet Spreadsheet?
tulip sleet
I think it's paragraphs
idle owl
@tulip sleet Sounds good
tulip sleet
include log extracts, etc. if you find something interesting
formal plover
stuff like: pro tip, unplug jlink when done using it lol
here's htop btw @tulip sleet similar to top, but prettier?
tulip sleet
just installed it: I like it gives complete path for process, which is very helpful; thanks!
formal plover
@tulip sleet You're welcome!
pastel panther
@tulip sleet Would it be worth opening an issue for the stuff I ran into?
solar whale
I need to get some sleep - long day tomorrow --- Tahnks for all the great work tonight - I will work on Raspi Pi toolcahin for building CP tomorrow.
tulip sleet
I'm writing up an issue right now for the Linux problems. I think it would be good to document it, especially since you're on an older but maybe not uncommon Mac veresions.
@solar whale I ran into problems running the .sh files in the arm download ./configure failure late in building pre-reqs. But I don't need it right now.
good night!
pastel panther
Night!
idle owl
@solar whale have a good night and day tomorrow!
glacial bronze
I did a little exploratory hacking to see how feasible it was for me to write example programs and I was able to get a functioning tachometer on the CPX using just the REPL. That's hecka neat. I think I actually will be able to contribute meaningfully.
idle owl
@glacial bronze That'll be great!
glacial bronze
Well, 99.9% credit to the author of the Arduino version. Brilliant to use the neopixels as a flashlight plus the light sensor
pastel panther
@glacial bronze You seem to have had the same experience I did the other day, working on my led matrix. It was just working before I knew it.
If you've never used one before it's easy to not understand how awesome a REPL can be
I've got some ideas in mind for how to make them more awesome, taken from some Ruby REPL enhancements I've seen, though memory might be an issue. We'll see.
glacial bronze
A solid utility would be the ability to save the REPL session to a file
glacial bronze
Yeah. More fully featured interactive editors like bpython can really chug even a Raspberry Pi type system
if the code gets complex enough
but really you program CircuitPython hooked up to a computer in any event, you don't really need an on-board editor
pastel panther
it would be an interesting exercise to see how small you could get. Theoreticaly your edior buffer could be dynamically sized to not waste memory, but overhead from the editor itself... I have no idea what would be involved
When I have some free time I might start poking around to see what super simple editors are out there. Probably would have to be written in c
glacial bronze
FWIW I Googled up a lightweight DOS text editor and it's 80 KB with a 64 KB filesize limit. Nano is ~2 MB

ah interesting. I wonder if its a driver issue
is it possible for you to upgrade the OS?
pastel panther
Yea, I suppose so. I've been meaning to do so but is having someone on an older version to test useful?
pastel panther
I'm not in a hurry (to upgrade or have a working M4) so if it's useful I can stay
Is ASF4 doing something different that needs a better/newer/faster driver?
slender iron
ah, the old one works?
then we should be able to fix it
my brain isn't working so well
pastel panther
Yea, 2.x works fine
slender iron
kk, yeah stay so you can test
pastel panther
Err, I haven't tried it on the m4
pastel panther
it's not m4 compatible, is it?
slender iron
2.x isn't
pastel panther
I have a logic8 if it's of any consequence
Though I'm not so sure it would know what to do with usb. Isn't it high-ish speed differential?
slender iron
those are awesome for other protocols
its 12mhz differential
I have some tooling and workflow for the beagle
we can hook you up with one if we need to
pastel panther
I will not turn away any tools that show up at my house ;P
slender iron
cool, well thanks! I'm off

@pastel panther I did a uninformed upgrade of the ubuntu from v 12 to v14., apparently shot myself in the foot.
pastel panther
then takes a while to re-provision?
I forgot the exact syntax but if I recall, the first time you set up you have to download and install a bunch of stuff
hollow tartan
do you use vagrant and virtual box on a windows machine?
hollow tartan
before, of course
pastel panther
(thought you might have un-borked it)
Did you have to do much setup for the dev environment after you got vagrant up?
hollow tartan
ah, yeah, the whole gcc compiler
pastel panther
You using something like this?: https://github.com/adafruit/esp8266-micropython-vagrant
hollow tartan
yep, that is the one.
pastel panther
it might suck but I'd suggest starting from scratch.
hollow tartan
I am going to bed soon. thanks for chatting.
solar whale
@hollow tartan I think he correct way to update the Ubuntu release from 14.04 to 16.04 is to reinstall the vagrant box and change the line in Vagrantfile from ``` config.vm.box = "ubuntu/trusty64"
to
config.vm.box = "ubuntu/xenial64"
@solar whale Hello. I backed up and chose Vagrant 2.0 to get Ubuntu R14. 4 . So I have a Vbox with what you have and I am trying to get gcc and xtensa-lx106 playing nice together, so it will build a loadable bin.
my $PATH has an ESP32 reference. is that correct? I think I noticed it yesterday when I had R 12 running good.
solar whale
@hollow tartan ok - good luck - I to sounds like you are building microoython at this time. Do you then plan to move to circuitpython as well?
@hollow tartan ok - good luck - I to sounds like you are building microoython at this time. Do you then plan to move to circuitpython as well?
solar whale
yes I did. lots of fun 😉
hollow tartan
make axtls
make```is blowing up
the /esp8266 it is looking for is actually /ports/esp8266
and the xtensa-lx106-gcc is not being found!
good night, leave any thoughts you have and I will read tomorrow. 
solar whale
@obsidian helm It does llok like the master buil at mircropythoin has also changed to but esp8266 in ports so yes - that is the way to build it. Not sure what the issue with xtensa is. - you shoudl; execut the make axtls in ~/micropython/ports/esp8266 . just curious Are you following this guide? https://learn.adafruit.com/building-and-running-micropython-on-the-esp8266/micropython-usage?view=all Of course there are many ways to do this,I'm just trying to follow along with what you are doing.
solar whale
@slender iron @tulip sleet just a sanity check - It looks like the 2.x build did not migrate to the new repository layout, correct? Tha is 2.x does not hac the ports folder. It gets a bit confusing when you switch between branches. if I go from 2.x to master, then the top level atmel_samd folder is still there along with others. Is there a simple way to get git to remove all the unused subdirectories when you switch branches. I think it is jsut git submoule update --init --recursive to make sure they are properly reinstated after a switch but that does not remove the unused ones. Not a big deal, just wondering if there is some git magic I should know.
drowsy geyser
Thaks for the reminder, @solar whale ! I did a pull this morning and the build was failing. I hadn't looked closely at it because I'm working on the multi-repo "Pulse"-like Python program that Scott wanted, but git submodule update --init --recursive fixed it....
stuck elbow
the metro m4 just arrived
I will do science to it
I was able to attach gdb to it with the black magic probe

Thank you @tulip sleet for attacking those high CPU problems so fast! I guess it's a Linux problem not specifically Linux on the Pi. I'll write up some of the other stuff like making sure you don't have too many other things plugged in via USB and what not, in a document like you suggested.
umbral dagger
@solar whale Re the esp breakout guide. Cool! I just got one of these to play with CP & IO. No idea what I’m going to do yet.
Ok... adequate caffeination level achieved. Time to try the latest CP on M4.
solar whale
Is that the ESP8266 or esp32?
umbral dagger
@solar whale 8266
solar whale
OK - I can help with that if you have questions - dont have any esp32s
solar whale
@umbral dagger when you start playing with IO, my main warning is put in some checks for failed connections. I try twice then reset the board if it still does not connect. That usually gets it back.
tulip sleet
@solar whale to remove stuff that isn't in a branch, you can use git clean -f. (It requires the -f because you could be removing stuff you want to keep.) git clean --dry-run (aka -n) will tell you what it will do to make sure. git help clean.
solar whale
@tulip sleet thanks!
tulip sleet
i have used it mostly up to now to clean up .orig etc. after fixing merge conflicts.
solar whale
Sounds good - just makes it very imoprtant to do a git submodule update every time you switch braches!
tulip sleet
yeah - I actually now have two clones for convenience, one for 2.x and one for master
solar whale
probably the smart way to go...
solar whale
sleep is overrated 😉
formal plover
Haha true true @solar whale
solar whale
@tulip sleet On the Pi - I tried apt-get install gcc-arm-none-api - installs all the right stuff, but it is an old gcc and fails the -lto stuff so it looks like a manual build is necessary. I thought I had done it inthe past, but it may have only been for the esp8266 under micropython - different tools....
umbral dagger
@solar whale I grabbed the toolchain from ARM's site
solar whale
@umbral dagger - for Pi? can you post alink?
umbral dagger
@solar whale a little more work to install, but it's the latest. That was for Ubuntu on intel
@solar whale https://developer.arm.com/open-source/gnu-toolchain/gnu-rm/downloads but doesn't look for be an arm/pi build. There's source, so...
solar whale
@umbral dagger I don't see an ARM build there but should be able to build it from the source - thanks
umbral dagger
umbral dagger
Oh ya.. that works immediately.
And if I put it back, everything works great
I can reload, then get back into the repl no trouble.
So it looks like an initialization issue. It's like main.py starts before the usb/serial thing is up & running
umbral dagger
yes
I just tried that. resetting with an empty CIRCUITPY lets me drop into the repl
solar whale
It might be good to add that to the github issue that Dan has open for linux.
formal plover
Yeah like @solar whale watch out @umbral dagger the M4, cranks up CPU usage
Just by being plugged in
tulip sleet
I think this morning's ee18b5ca commit fixes the CPU usage issue. I have not seen it after that. However @dastel's note above documents a continuing issue.
will be off line for an hour or two
umbral dagger
@tulip sleet @slender iron It's as if (or really is) the USB input processor doesn't have a chance to finish initializing before code starts running, and gets preventing until code stops running.
@tulip sleet @slender iron Updated my comment to include the case where main.py does NOT loop forever.

tidal kiln
question on updating something in the bundle. did this originally to get it:
- worked in personal repo
- personal repo forked into adafruit
- made pr on adafruit fork to get into bundle
- bundle now has adafruit fork
now if i need to update my code, what's the process?
manic glacierBOT
pastel panther
@tulip sleet finally got around to filing the ticket, sorry for the delay
tulip sleet
@tidal kiln maybe fork a new personal repo from the adafruit one and then delete the old personal one. That will normalize the workflow so your personal one is downstream from adafruit/. To make a change, create a branch in the personal repo for this change, make the change, commit and push it. Then you'll probably see a pull request button both in the adafruit and your repo (you can always create one manually). This is how we normally do it in CPy: Scott and I work in personal repos on temporary feature or bugfix branches, then submit PR to adafruit/circuitpython. When accepted, we delete the temporary branch. When the PR is accepted, in the personal repo, we do git fetch upstream, then git checkout master [if necessary]; git merge upstream/master, and then push to the personal repo so it's sync'd with adafruit.
tidal kiln
@tulip sleet thanks. that was my thinking as well.
but wanted to make sure before i nuke my original repo
umbral dagger
@slender iron pull & rebuilt & flashed. Same behaviour.
tulip sleet
Scott likes to name the upstream remote as adafruit instead of upstream, so the source is clear. I haven't started doing that consistently yet; I have muscle memory for upstream.
tidal kiln
i name my remotes after power puff girls 😀
slender iron
@umbral dagger I think @tulip sleet is right that we're not handling ctrl-c correctly
what should I do with text typed while main is running? save it for the repl or ignore everything but ctrl-cs unless input is going?
pastel panther
If it's being echo'd, I would say save it. Otherwise ignore it
tulip sleet
I think you should flush everything before the ctrl-C. That's how it works in regular Python and in a shell.
pastel panther
I think the friendlyist thing would be to save it but make it very clear that it won't do anything until you stop main
Also consitency with @tulip sleet 's comments would be good
tulip sleet
just tried it while True: pass, then abc<ctrl-C>. abc is echoed but not taken as input
in python3
slender iron
ah ok
slender iron
i am
though you can if you like
I can look at descriptor stuff
it should be fiixable in circuitpython code
tulip sleet
I'll look briefly. was going to compare it with 2.x. Descriptor - you mean the duplicate disk name stuff? not sure
slender iron
2.x is different because it caches the usb input in an interrupt
right now we only read from cdc when usb_read is called
tulip sleet
if you're on a roll go ahead. I can finally get to busio and analogio. but if you have something else, i can look too.
can the interrupt handler peek without reading? I know right now it has a one-char rollback, I think
slender iron
the only interrupt we get currently is the complete callback after we initiate a read
go ahead and take a look. I'll fix asf4 some more 😃
tulip sleet
k😁

I gotta go help a friend for a bit in two hours too

cool thanks. i'm only just now getting a chance to go hands on. so i'm like at t=0

No worries!
There are two notes pages there - Installing Debugging Components, and Compiling

Cool! I hope it's helpful.
Oh, I should have said the commands are for UINX-like systems (MacOS, Linux, Windows 10 Bash environment).
drowsy geyser
Thank you, @formal plover ! It's really just notetaking of how I got it working. Most of which is other peoples' advice!
formal plover
@drowsy geyser you're welcome! I need to make something like that for tracking issues per @tulip sleet's suggestion
drowsy geyser
Oh? The "issues" link in GitHub isn't sufficient?
pastel panther
I was about to say the same thing
Though it would be nice to have a breif summary like
- OSX no serial console
- RPi: CPU is a toaster
- Windows: bla bla
Something like that would be useful as a pinned post
drowsy geyser
That's true. There may be more information we want to capture that would clutter up the issues page. Namely, historical information.
formal plover
Yeah at least for where things are with the M4 right now @drowsy geyser
idle owl
Learned today that an older CPX might not communicate consistently with a newer CPX over IR. I noticed the transmitters were different on the two I have, but figured they would operate the same. Apparently not. Figured it out with MakeCode, but I imagine it might happen with CP when we get to it.
drowsy geyser
@formal plover I'm working on the "Insights"-like program for Scott. It will generate statistics across multiple repos and sub-repositories. Since it's going to use the GitHub API (GraphQL) it might be handy for your task, too.
formal plover
Once things go out of alpha, might not need it anymore.
@drowsy geyser nice! I saw some discussion on that. Are you using the GitHub API?
drowsy geyser
@formal plover Yes. There's an interface library called Graphene that abstracts away all the JSON query construction so you don't have to write code to do it!
formal plover
@drowsy geyser that's fly
Well I'm excited to see the end results!
Keep up the good work @drowsy geyser!
slender iron
I'd like to keep the issues list as the location for port status

@slender iron That makes a lot of sense.

I'm really anxious to try the JLink on Linux and see how it is....

You're welcome!
@pastel panther are you working on your M4 yet? Or do you still need more info to get started?
tidal kiln
Could not connect to target.
Please check power, connection and settings.

formal plover
@tidal kiln what are your settings? I got it to work fine that way
Wait you're trying to connect via jlink right?
tidal kiln
yep.
idle owl
@tidal kiln Yeah I did. I don't have a 9v power supply.
tidal kiln
i'm powering through USB, but with an AC adapter

I'm on MacOS but I used the JLinkExe commandline util.
That's what I did for jlink stuff. Powered USB from a wall plug... 5 port wall adapter thing.

formal plover
@pastel panther ah gotcha. Good deal. Just wanted to make sure you weren't left hanging
pastel panther
Nope, I'm good, thanks. Just have to figure out why my metro m0 doesn't want to talk to my SPI led matrix
tulip sleet
I have some fixes so you can ctrl-C main.py. Tested on Metro M0. The REPL exits every 30 seconds unless I only enable one MSC device (with mscdf_init(0);). Then it's fine. @slender iron I can make a PR for this as an intermediate step. OK by you in your progress?
aaah doesn't work compiled with optimzation. not yet...
pastel panther
@formal plover It's a matrix I got from the SparkFun dumpster dive. It was previously working fine with 2.1 on my feather m0 express. It may well be a wiring issue. I'm sure I can figure it out.
Is this diagram roughly correct with regards to SPI pins? http://www.pighixxx.com/test/wp-content/uploads/2016/07/Metro_pinout_final.png

@drowsy geyser What'd you get for a Linux system?
drowsy geyser
Just a cheapo refurbished system from NewEgg. Nothing special. I didn't want to get a top end powerful system because I want to spend that money on a NAS.

If I need power these days I just use a cluster at work. 😃
umbral dagger
@drowsy geyser After close to 15 years of buying Macs I was amazing how cheap it was to put together a top end Linux system. Granted, I'm just using the onboard video (which is pretty in line with Apples video choices).
@drowsy geyser There's always AWS or Azure if you need the power.
drowsy geyser
@umbral dagger I work at Microsoft, so I have literally thousands of cores of compute available.
umbral dagger
@drowsy geyser Ya, I saw that.

Documentation note on https://github.com/adafruit/micropython-adafruit-bitmap-font
bitmapfont.py can be in /lib/ but if the font.bin is there, it won't be seen and init() will fail on line 28
putting the .bin in device root works
Relevant tutorial: https://learn.adafruit.com/micropython-displays-drawing-text/software right at the top
tulip sleet
@glacial bronze This can be fixed by using BitmapFont(..., font_name='lib/font5x8.bin') as well. Also, we could change the code to look at bitmapfont.__file__. That returns the path to where the module was imported from. Feel free to submit an issue on the library.
glacial bronze
I still haven't figured out GIT. It's on my to-do list for tomorrow night :v

pastel panther
@formal plover @tulip sleet Thanks for your help. I think that diagram is just wrong. I just looked at the board and SPI only goes to the header and not to any of the other pins
tulip sleet
@pastel panther well, that's a Metro 328 (Arduino semi-clone), not a Metro M0. https://www.adafruit.com/product/2488. The schematic on that one does show SPI pins on the main headers: https://github.com/adafruit/Adafruit-METRO-328-PCB/blob/master/Metro Mini Schem.pdf
pastel panther
On the otherhand I think I made a boo boo with the MetroWing
Yea, I just looked at the board for the m0
tulip sleet
The Metro 328 has a tilted CPU chip and doesn't say Express. The Metro M0 express has a straightened chip and says Express. The M4 has a tilted chip and says Express. This is kind of like which is the Biscayne, which is the BelAir, and which is the Impala.
pastel panther
Yea, I know. I just ended up with that diagram as I didn't see anything similar for the m0 express and I mistakenly thought they were the same

note to self: printing to the console can be as effective as a sleep at slowing down your code
@slender iron is SPI working as expected on the M4?
slender iron
nope, its not implemented yet
you shouldn't be able to import busio
dan and I are still in USB land
pastel panther
Ok. I can't currently tell if it's importing because of the CDC issue
Is there a general roadmap of features that need to be implemented for 3.0 to be ready for release?
slender iron
yeah, its the 3.0 beta issue then the 3.0 ones
they aren't well sorted though
busio will come after USB has settled down since it enables the spi flash
pastel panther
ok, cool
slender iron
I'm brewing up some awsome stuff for usb I think
hopefully get to the point where we can change the usb funcitonality enabled in boot.py
pastel panther
ooooooh
I'm eager to see how that works. I've been watching the commits to get a better idea of how the code is working.
slender iron
working on a python script to generate the descriptors to be built in with the idea that it can be used in boot.py later
pastel panther
cool
slender iron
if you have code questions feel free to ask. I'm happy to point you places
pastel panther
Will do. I think I could get a decent lay of the land if tracing paths wasn't such a chore. I'm still haven't loaded the code in something that can index it for me yet to make finding function definitions a bit easier.
slender iron
yeah, I'm low tech and use ag which is essentially grep
slender iron
yeah, I should probably figure something out to do that
pastel panther
I've been trying out Atom and I think it has a ctags package so I might try that next
huh, apparently it has ag support with the atom-codesearch package
pastel panther
also a couple other search engines in the same package
Yea, I'm a bit annoyed with that so far. They seem to be reproducing on their own

@tulip sleet built latest CP 3.0 Master loaded to M4 and connected to Linux box - running cool and no 100% udevd processes! Thanks!
formal plover
@solar whale glad to hear that. I'll have to give it a try this weekend.
solar whale
Notice an interesting quirk - If you have the board runnig on 9V and disconnect from USB, then reconnect - it bring usp CIRCUITPY but cannont connect to REPL unless I reset the board. Same happen on Mac - I suppose this makes sense since the CP board is not RESET so it does not initialize the conenction for the REPL
@formal plover I'll be happy to help you with Arduino any time as well. I hope to have my notes written up today.
formal plover
@solar whale Awesome, thanks! We'll have to devise a plan for testing. Lady Ada said it's more stable than CircuitPython
solar whale
@formal plover seems to work well and seesm to support many I2C devives with no problems
solar whale
hmm - did somethig change regarding I2C on 2.1 with 2.1 Bundle- whwnever I try to init an i2c device, I am getting ```>>> import mpr121test

solar whale
appears to be a bug in i2c_device but I am not sure when it was intrduced. Has anyone been able to use an I2C device with 2.1.0 and the 2.1 Bundle?
tulip sleet
@solar whale we put in a test for buffers of length zero. it may be that particular driver which is passing zero-length buffers. https://github.com/adafruit/circuitpython/issues/358
solar whale
it is in i2c_device.py
@tulip sleet I was jsut looking at the issue - but the error is in the i2c_device.py - part of bus_device in the Bundle.
# Verify that a deivce with that address exists.
while not i2c.try_lock():
pass
try:
i2c.writeto(device_address, b'')
except OSError:
raise ValueError("No I2C device at address: %x" % device_address)
finally:
i2c.unlock()
self.i2c = i2c
self.device_address = device_address
should this be changed to write b'\0' ?? I think the write is just tsting for "aliveness"
tulip sleet
@solar whale ah, so it's testing whether the device is there by writing b''. Maybe there's a different way to do that.
solar whale
it breaks all I2C examples I have
@tulip sleet would it be safe to just write a b'\0' is that the correct sytax to write a zero?
tulip sleet
@solar whale you could just remove that try/except test for now. Not sure whether all devices would tolerate receiving a zero.
just remove everything before self.i2c = i2c
solar whale
@tulip sleet its nota crisis for me - just testin new build - but this will break a lot of stuff.
tulip sleet
I'm not that familiar with i2c transfer expectations at that low-level. We might need to back out that change, or not. Could you reopen that issue and point out the problem with i2c_device?
solar whale
I'll enter an issue at #358
manic glacierBOT
solar whale
@tulip sleet how do I re-open the orginal issue?
tulip sleet
I see a button on the empty comment form at the bottom of the issue that says "Reopen issue". Do you see that? Maybe a privs thing.

@tulip sleet I see it, too, and I h ave minimal repo privs.

The compiler is clever... that s to say... it's rather obtuse until you get your head around a few things. Then you sit back and think "huh... that's clever"
solar whale
clever is great until you try to debug....
umbral dagger
uh huh
solar whale
BTW I looked at the DEBUG=1 setting it it does not appear to invoke O0
umbral dagger
HEAVY use of macros... grammar.h is a prime example. It gets included into compile.c several times... with different macro definitions each time to extract different bits of the rules.
Thus no direct, explicit wiring in the compiler... it's all done at compile time based on different interpretations of the grammer rule file.
That slight criticism aside, I like how it's putting ALL the compile rule information in one place.
Once that's clear, it all makes sense.

solar whale
@tulip sleet Thanks - I was just curious how the optimization impacted the code for debugging. Sometimes it can make it hard to trace - especaill at the assembly language level.
I was used to turning off for debug builds. I'm sure it has a huge code size impact!
tulip sleet
I turned off -Os for SAMD21. It overflows flash by 111kB!

@tulip sleet Not sure if you saw this earlier - is this a bug ? If you have the board runnig on 9V and disconnect from USB, then reconnect - it bring usp CIRCUITPY but cannot connect to REPL unless I reset the board.

temp and pressure look OK - I'm not underwater but the BME280 said -3m so its not too different
meager fog
ooh yah
you can optimize the alt measurements by telling the sensor your sea-level pressure
since it varies every day
tidal kiln
can you compare pressure to a local weather station?
tidal kiln
pretty healthy change for 'minutes'
solar whale
weatehr station say 1014.78
tidal kiln
standard day sea level = 1013.25 hPa
so the negative alt at least makes sense
weather station agrees nicely
solar whale
now have bme280 next to it - it reads 1013.37 - bmp280 still 1014.2

@solar whale I'll leave you to it then. If I answered it, it'd be getting all the info from you anyway.
lofty topaz
@tidal kiln Yes, thanks for confirming. I have two CPX's now and wanted some data to send over the IR beam so I popped into that page, scarfed the code, and assumed the sensors were there.
solar whale
ok - Ill respond in a few minutes
tidal kiln
why did segger camel case their executables? thank goodness for alias.
idle owl
@lofty topaz CircuitPython IR support is still being developed.
lofty topaz
I know I've been out of the developers realm for a few years now but are you saying "camel case' is nolonger used?
@idle owl Yes, I know. Thought I'd try and see how far along it is.
tidal kiln
no, i'm just whining. on linux and the segger tools are mixed case for some reason. makes using on cli 'fun'.
alias jlink='/opt/SEGGER/JLink_V620g/JLinkExe'

@lofty topaz This works for receiving and decoding many IR signals (might still fail to decode some, I'm not sure): https://github.com/adafruit/Adafruit_CircuitPython_IRRemote There's a module ported by someone who uses IR for communicating between accessibility devices: https://github.com/cyborg5/IRLibCP

@tidal kiln I could not agree more. It smacks of a company not familiar with unix.
tidal kiln
or maybe they have stock in <SHIFT> key companies?
umbral dagger
@tidal kiln Also, I hate things going into /opt ... that's what /usr/local is for!
idle owl
The first one I've used on the CPX to receive signals from remotes and another CPX loaded with MakeCode. I haven't used the second one with the CPX. I also haven't made a CPX send IR signals using CircuitPython. But that's where I will start.

@tulip sleet On the Pi after installing many many packages and the crunching for a looong time my arm gcc build faile while building "genautomata" ...sigh - Is there where your failed as well? I'm about to give up on the Pi as a development platform.
I think @formal plover will just have to get a "real" computer to build CP. 😉
tulip sleet
@solar whale mine was somewhere in build-prerequisites.sh. Compiler error reporting is too harsh for ./configure (perhaps remove -Werror). Found this, but I'm not sure it's relevant: https://stackoverflow.com/questions/27867271/zlib-harsh-compiler-warnings-and-configure-test
formal plover
@solar whale Bwhaha! I have one. It got moved to a really inconvenient place after we set up the nursery
solar whale
Mine failed there on the firs try, but I rerean it with --skip_steps=mingw32 and build-prerequisites completed.
tulip sleet
how did you know to do that?
pastel panther
I read the GFX lib
solar whale
It inthe intall guide pdf
pastel panther
oh, nvm
solar whale
part of the .tgz file
tulip sleet
I was using lesspipe to read the pdf on the rpi. I got that from google. But I just skimmed it. Should have read it on the big screen computer.
it converts the pdf to text
solar whale
How-tobuild-toolchain.pdf - it listed all the packages too so I installed tehm all - except there is no build-esentials
tulip sleet
I did see those packages (long list) and installed them, but I should have read further. Anyway, it was mostly to build mpy-cross and the one you built works fine on both jessie and stretch so I uploaded that to the 2.1.0 release.
solar whale
I was able to build mpy-cross and bossac so I can use the arduino stuff on the M4 - I think I'll be happy with that - Sorry @formal plover
tulip sleet
@formal plover @solar whale this may help: https://www.raspberrypi.org/forums/viewtopic.php?f=29&t=99127; points to https://github.com/ARMinARM/arm-toolchain-build-scripts. But it's a couple of years old
I like that ARMinARM joke.

@tulip sleet what do you need me to look at today?
I'd be down for a voice chat. I've got some ideas about the supervisor
tulip sleet
sure - now is fine
slender iron
👍
solar whale
@tulip sleet @formal plover taht builds gcc 4.8.2 - currnent build is 6.3.1 - worht a try, but probablt the same a apt-ge install arm-gcc-none-eabi - which won't support CP build.
I have to go for awhile -it is too nice outside to stay in all day!
tidal kiln
should i flash a bootloader on the m4 first? or just use one of the cp bins?
idle owl
Flash the bootloader if you want to be able to test using the .uf2 firmware files. That's what I've been using.
tidal kiln
where to grab bootloader?
idle owl
I know its here: https://github.com/tannewt/uf2-samd but let me find the last one I loaded and I'll copy the file here.
tidal kiln
one of the ones he posted here?
idle owl
Yeah that's the last one he posted, and the last one I flashed.
I haven't built the bootloader myself yet.
tidal kiln
yeah, i'll worry about building next, first just want to flash an existing build
can i use the uf2 with jlink?
idle owl
Totally understand that
Oh wait... you're right that's not it
hold on.
No you can't use the .uf2 with jlink.
tidal kiln
jlink -if SWD -device ATSAMD51J19 -loadbin bootloader.bin,0x0
idle owl
That's the bootloader from the 24th, which matches the last update to the uf2 repo.
tidal kiln
that look correct?
idle owl
For me the address was ,0
Otherwise I think so? I used JLinkExe to do it
connected first
then did loadbin
so I never ran exactly what you did, but other than the address being different when I did it, it looks right
formal plover
Wait, I thought there's one from the 26th now
idle owl
@formal plover @tidal kiln There's might be. Might want to ping Scott before you flash that... I might be behind.
tidal kiln
oooo. fresher produce.
idle owl
I think that's the firmware, not the bootloader...
formal plover
I thought it has both
idle owl
You might be right. I probably misunderstood.
tidal kiln
well. let me try...
idle owl
If you end up with a neopixel, it's the bootloader. If you end up with CircuitPython, it's the firmware. 😃
idle owl
Yeah but I think travis builds both for the firmware
formal plover
@idle owl gotcha
idle owl
Since you can still use the jlink to flash a .bin firmware file.
pastel panther
both could be a bootloader, just diff formats I think
formal plover
True true
idle owl
Like I said, I could be wrong. That's just what I understood it to be.
pastel panther
hey @idle owl, You've done some CP library work right?
formal plover
I'm probably wrong @idle owl Lolololol
idle owl
@pastel panther Yeah for the CPX
pastel panther
@idle owl I was looking at the AdafruitGFX lib and I didn't see a CP equivalant, is that right?
tidal kiln
i get....nothing
idle owl
@pastel panther I don't know for sure. Cursory search says you're right. A lot of the CP libraries are included in the bundle, so that's always a good place to start looking for whether or not it exists already. Otherwise, a more thorough search of GitHub would be needed.
@tidal kiln That's not a very good prize

did something
idle owl
@tidal kiln And you disconnected the jlink and did the double-tap to reset to see if it would go into the bootloader?
tidal kiln
no
pastel panther
@idle owl Cool, separate from if it's needed, if I were to port something like that to CP would it make sense to write it in python or try to keep parts in C for performance? Is there a provision for including C/compiled code with a CP library?
idle owl
@pastel panther Scott wrote a guide for contributing libraries to CP. https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library/overview All of the library work I did was either Python or CircuitPython. I don't know if there's a provision or not. Scott might have a better answer. @tidal kiln has also written some drivers/libraries, so he might also have some ideas.
pastel panther
Oh right.
idle owl
Did you start already
tidal kiln
me? start what?
idle owl
Try to connect to the REPL even though nothing seems to be happening. We ran into that but that was supposed to be fixed iin the latest build
Like nothing would happen, we'd connect to the REPL, and then it would show up
tidal kiln
nothing is even showing up in dmesg
tidal kiln
it's name is more promising
idle owl
Valid

weeee ASF docs!

hello world
Yes!
solar whale
@idle owl @tidal kiln you are mking it look so easy - Not like the "the old days .... " 😉
idle owl
@solar whale Yeah all of 2 days ago.
tidal kiln
thanks @idle owl i've now made baby step 1.
idle owl
@tidal kiln That's how it always starts. Good job!
tidal kiln
so the s3 bucket is just cp builds?
idle owl
That's what I thought anyway.
tidal kiln
seems like it. flashing the .bin from there did nothing.
flashing the bootloader.bin and then using the uf2 from the s3 bucket worked fine though.
idle owl
That's the end goal anyway.
tidal kiln
and i guess the .bin's are for loading cp with bossac
once you've got the bootloader on
idle owl
Ah that makes sense
lofty topaz
@idle owl @tidal kiln Howdy, just been kibitzn your conversation. I must say, that's hacking at it's best. Glad to see the M4 is progressing. 🍸
tidal kiln
@lofty topaz thanks. i'm days behind everyone else. i'm probably benefiting from that.
idle owl
@lofty topaz Every time we get a new build there's something new. They're doing so well.
idle owl
@tidal kiln Wait on using main.py and code.py... I'm pretty sure they're still causing issues with connecting to the REPL. You can create a file and import it while in the REPL (I keep blinky.py around, that little red LED Is so satisfying!), but if you have a main/code, you can sometimes connect to the serial connection, but you can't give it any input or kb interrupts to get to the REPL.
tidal kiln
k. thanks. mainly just making sure i got the flash/load process down at this point.
lofty topaz
tidal kiln
still curious where the latest bootloaders live?
lofty topaz
@formal plover I use to tell people "My brain is not building today, sorry!".
idle owl
@lofty topaz code.py is where your code lives. It's meant to be easier to understand for beginners. main.py is a carryover from MicroPython
@tidal kiln I think they're at that repo I linked. I think you can build them there. Scott posts them prebuilt for us when we need to test after he commits.
lofty topaz
@idle owl Dang, I was afraid of that. You see, "main", whether for the start of C or the runtime in Python, it's a rock that shouldn't be moved nor changed. I hope "code.py" doesn't backfire and confuse beginners.
My opinion... ><>
idle owl
@lofty topaz There's no difference between the two. CircuitPython looks for code.txt, code.py, main.txt, and main.py in that order, I believe. The .txt files are included because people just starting out may not have editors that understand .py files, so we want them to still be able to plug in a board and get started immediately.
lofty topaz
@idle owl I understand, it's just giving choices at the fundimental level requires more explaining. I tend to view that sort of stuff as "noise".
idle owl
@lofty topaz You're coming from a solid background. You're not really the target audience for code.py 😃 I think by the time it starts to matter whether someone is using main.py or code.py, they'll have enough knowledge to understand why one is needed over the other. That's the goal. Teaching.
tidal kiln
now to read the 1732 page SAMD51 datasheet to see what we've got...
idle owl
@tidal kiln See you in a month..?
tidal kiln
maybe. not sure i'm that fast of a reader though.
umbral dagger
@tidal kiln @idle owl haha
pastel panther
@tidal kiln good luck, take a towel
umbral dagger
@idle owl @lofty topaz I like main.py. To me it says “this is where it starts” even if there are other files there.
pastel panther
my problem was "oooh look at all these peripherials!!!!!!!!!" and then realizing I have no idea how to use them. That's how I ended up here actually; CP 3.0 as a ASF4 app reference
umbral dagger
@idle owl @lofty topaz code.py is great if there’s just one file. And I agree it is more beginner friendly. So having both as options is excellent!
idle owl
@umbral dagger That's exactly the point.
pastel panther
@umbral dagger I was in the middle of typing the same thing
main.py by itself is kinda like "wait, do I need more?"
lofty topaz
Just one file. Why does that make a difference. Please, I'm only trying to understand. If they are suppose to be the same, then what's the difference?
pastel panther
lofty topaz
And what if there are both?
idle owl
@lofty topaz It gives beginners a simple place to start while leaving the options open for people who understand it already to use main.
@lofty topaz Then it reads them in the order I posted earlier. Finds one, and stops.
idle owl
So if you have code.py and main.py, the first one will be read and that's it.
lofty topaz
ok, got it.
tidal kiln
just options
idle owl
Yep
pastel panther
This has the code behind that choice if you're interested:
https://github.com/adafruit/circuitpython/blob/master/main.c
around line 134
lofty topaz
Why isn't it called code.c ???
pastel panther
because it's c and no CP
tidal kiln
python isn't c
lofty topaz
just kidding... ><>
umbral dagger
ah.. ya.. @tidal kiln covered that 😃
pastel panther
sometimes it's hard to tell a person kidding from a beginner with genuine questions
tidal kiln
this can all change with time as user experience is gathered
lofty topaz
I'm sorry, I was just trying to reenforce my point.
idle owl
I actually use it to my advantage. Sometimes I'll use main.py for working code and code.py for testing other people's code. So someone has an issue, drop their code into code.py and it'll let me sort it out without moving or renaming my working code.
@lofty topaz Don't apologise. Discussion is always good.
umbral dagger
Although, I don't get the rational of having .txt versions in addition to .py versions. It is python code.
idle owl
And @tidal kiln is right, as things progress, and the user experience becomes more solid, things can change if it makes sense.
umbral dagger
Maybe to accomodate people using editors that insist on using .txt ??
pastel panther
yea
idle owl
@umbral dagger Exactly
lofty topaz
@idle owl See that? Now you got experts asking questions. Told ya.
pastel panther
?
idle owl
@umbral dagger So total beginners who ordered something, got a Trinket with it, have never coded anything and only have Notepad can at least get started.
umbral dagger
@idle owl makes perfect sense. We loose sight of what it's like as a beginner.
pastel panther
the more I think about it, a CPX with a simple text editor is an amazing way of learning to code
