@drowsy geyser It's been ages since I dabbled with ML (my grad work was ML + NLP based).

@umbral dagger Or an NTP-synced RTC board. They have a good selection in the Adafruit store. π
@umbral dagger Cool! I'm developing a high-dimensionality (4,000+ dimensions) distributed Euclidean distance algorithm to determine "likeness" of documents (or other data sets) in large (~10,000 cores) cloud compute environments.
umbral dagger
@drowsy geyser Haha.. the vast majority of my prototyping supplies come from Adafruit these days. Especially since I largely switched from AVR to SAMD.
sick creek
my friend at Microsoft Flux study azure machine learning from coursera and he is in 3 week spot right now
drowsy geyser
AxureML is basically a front end to R....
umbral dagger
@drowsy geyser Nice.
drowsy geyser
They're still working on the "distributed" part of it.
umbral dagger
@drowsy geyser By "core" you mean CUDA cores or (e.g.) i7 cores? I'm assuming the former.
drowsy geyser
The former.
umbral dagger
Well.. this got away from CP ...
drowsy geyser
Indeed it did. Good to point that out. I forgot I wasn't in #general-chat.
umbral dagger
@drowsy geyser To bring it back... I'm wondering just how much muscle the SAMD51 brings to CP. Could it run some basic Python ML libraries. There's loads of ML/AI work being done in Python.
@drowsy geyser I might try to find out with this SAME54 eval board I just got.
sick creek
@umbral dagger you could send data from CP device to cloud for example to process it using python there with jupyter notebooks
drowsy geyser
That would be cool! Perhaps @slender iron could chime in on the amount of extra power in the 51.
umbral dagger
SAME54 and SAMD51 are covered by the same data 'sheet' (is it still a datasheet when it's 1700 pages long?)
drowsy geyser
Data book? π
umbral dagger
@drowsy geyser I've had chats with him about it. I want to see how hard I can push it.
sick creek
@meager fog how much power M4 chip bring more than M0 to Circuitpython?
umbral dagger
@sick creek To start with, consider the massively large flash & sram space. Then consider the clock going 48MHz->120MHz.
@sick creek Depending on which version of the SAMD51 is used, it can have as much as 1M flash and 256K sram. That's pretty non-trivial.
drowsy geyser
@umbral dagger I can't wait to get my hands on one! I want to start seeing just what I can do with it, but I'm not helping enough to justify asking Scott for a prototype.
umbral dagger
It makes me stop in wonder when I remember that I started out with an 8-bit CPU at 1MHz, 8K ROM & 48K RAM. AND managed to do some cool stuff.
@drowsy geyser grab a SAME54 Xplained board from Digikey.

@umbral dagger My 8 bit Z80 saved Zenith $40 million a year.

lofty topaz
@drowsy geyser Hi, how ya doin?
umbral dagger
@drowsy geyser Mine arrived a few minutes ago, thanks to @slender iron for turning me on to it.
@lofty topaz I did so much Z80 work (hand assembling some...for ZX81/TS1000), same for 6502. Glory days! I once built a Z80 system on a 6"x8" wirewrap board that was PACKED and no more capabile than what's onboard an ATMEGA328.
drowsy geyser
@umbral dagger Thanks! Ordered!
@lofty topaz Good, thanks! Been really busy with work...
umbral dagger
@drowsy geyser Like I said, same datasheet.. but with onchip ethernet
lofty topaz
@umbral dagger Do you remember C3 01 00
drowsy geyser
@lofty topaz How have you been?
umbral dagger
@drowsy geyser SDcard support onchip as well.. the eval board has a full size SD slot.
@lofty topaz That does look familiar.
lofty topaz
@drowsy geyser Much better. When it rains, it pours. Get yit back together.
@umbral dagger I always had my Z80's jmp 0100 to use the first 0FF bytes for program data.
umbral dagger
@lofty topaz I was thinking that C3 was a jump.
@lofty topaz Amazing.. after so many years.
lofty topaz
Everything I wrote in assembler for the Z80 started out C3 01 00.
It is a jump.

RadioShack was actually useful back then.
idle owl
@split ocean I have to run for bit but I want to send you a zip with the current state of my CPX, and have you try it looking exactly like mine. If it works, you might need to reflash the CPX, it could have something deeper causing the issue. As for your question yesterday, yes, your code can cause memory errors, it's not just the .mpy that can do it. I've even managed to get code to crash CircuitPython completely and reboot into safemode. π
@split ocean
I'll be back in a bit.
tulip sleet
@umbral dagger M4 clock is 120 MHz vs 48 MHz. Plus it has hardware single-precision (not double) floating point. In MicroPython/CircuitPython, that's truncated to 30 bits instead of 32 bits (you lose the two lowest bits of mantissa precision). The internal CPU architecture is more pipeline and fancier, so that also gains. Rough experiments have yielded maybe 6x improvement, but it depends on the program.
umbral dagger
@tulip sleet 6x is a nice sized improvement. That performance boost, plus the memory increases (more code, and more data) will be fun to explore.
idle owl
Do any of the M0 boards charge attached lipoly batteries?
tidal kiln
the feathers do
idle owl
Oh keen. Thank you
tidal kiln
feature of all feathers
idle owl
Excellent. I have only the M0 Express. But I've also never had a lipoly so I've had no need to charge one. I wanted to get one for testing, but I wasn't sure if I needed a separate charger. I do not!

@meager fog hi, nice to meet you!
formal plover
Hi @stuck elbow!!!
umbral dagger
@stuck elbow Hi there!
tulip sleet
@meager fog whoops, missed your earlier msg. m4 PID is 0x8015 for CPy right now. That overlaps with Feather M0, not Express, so I guess Scott mean that to be temporary.
slender iron
@meager fog just hipchatted you a new bin
@tulip sleet I think its a bootloader thing. we'll see what it takes to get her going
meager fog
~wow~
slender iron
lemme go try
meager fog
ok
slender iron
I need a new bossa right?
slender iron
kk
meager fog
if you build add to the relesase, i put the m4-friendly bossa there
slender iron
kk
meager fog
you need wx
you're probably saying to yourself "but its a command line tool, why does it depend on wx?"
slender iron
make bin/bossac worked
meager fog
yay great
slender iron
not sure the binary works π
sick creek
i guess it need binary to work I guess
slender iron
yup, rebuilding circuitpython first
meager fog
want me to try on the SMT m4?
slender iron
nah, I think its an interaction with the bootloader
all my testing is with the jlink loading at 0x000
sick creek
I can run the bossa linux compile command in my windows 10 Ubuntu terminal π neat
Now I wish I have M4 board
fresh isle
It is so cool to see this interaction. thanks for sharing the work here!
slender iron
@meager fog I'll try loading it with jlink after the bootloader
meager fog
ok ill keep samr21'ing - ill give you a variant for circuitpy when its done π

if you have windows 10 and think using ubuntu command in it, got Fall Creators update towindows 10 so https://www.microsoft.com/en-us/store/p/ubuntu/9nblggh4msv6

@meager fog the bootloader code is in the samd51 branch right?
slender iron

formal plover
J link for the win!
sick creek
@tulip sleet you have M4 already?
tulip sleet
@slender iron I'm ready to make a new lib bundle. Can hold off on CharLCD and AMG8xx. I do want to fix the naming for ccs811. I have PR for that but could accept it myself. We can make another bundle in a few days. Want to get fixes in for 2.1. Do you want to review it or should I just do it?
@sick creek I have an earlier prototype: newer prototypes arrive tomw
slender iron
@tulip sleet just do it. whats wrong with the naming? I thought the new PR I accepted had the correct capitalization
tulip sleet
in the directory, but the actual .py file was Adafruit_CCS811.py instead of adafruit_ccs811.py. I only noticed that afterwards. Also a typo in .travis.yml.
i have a similar PR in for AMG8XX.
slender iron
ah ok
stuck elbow
what's the mcu on the new m4 ones?
slender iron
SAMD51J20A iirc
tulip sleet
Yeah, just capitals (for the onlookers): http://www.microchip.com/wwwproducts/en/ATSAMD51J20A

Just spent $340+ to resupply my workshop. Adafruits freebies were a very nice touch. Thanks @river quest

Not really. Just more Arduino stuff.
Oh, ah a Trinket MO a CPE a perma board and a Gemma?
slender iron
@stuck elbow https://www.adafruit.com/free
lofty topaz
Yeah, that's the link. Way cool. Just when I was about to order I saw the banner.
Your talking about $40 worth of very good stuff for free. How they do it is beyond me.
Now I need to get a job. π
tulip sleet
@slender iron have to go out for a few hours, but will finish and publish bundle this evening
idle owl
@split ocean Did you get everything you needed back to a working order for your stream? I know it's coming up quick enough that we're not going to troubleshoot right now but I wanted to make sure that you were at least good to go for that.

@slender iron im goin' in 30 minutes to do a talk - so let me know if you want me to retry something. i can also just jlink
slender iron
@meager fog at lunch with @timber lion will keep looking afterwards
idle owl
@meager fog Have fun at your talk!
manic glacierBOT
umbral dagger
I really kind of want to put one of those 8Mbyte SPI flash chips on a TrinketM0. It's like a monster truck... no practical value, but it can be done.
stuck elbow
there is a trinket m0 haxpress board definition in the repo
you will just need to write the header file for your flash chip
also, I found it's much easier to just build your own trinket using the same chip in a larger package, than to solder to those tiny legs
split ocean
@idle owl thanks, I was all good for the stream, I showed color and accelerometer bahavior and only mentioned that sound would be coming as it is developed into express.mpy
idle owl
Yeah that was pretty great, lol
split ocean
I think I'll focus on getting it all working using the regular libraries for the first iteration of the guide, then move to express when it's ready
umbral dagger
@stuck elbow Ya, that was based on https://daveastels.com/2017/09/01/trinket-m0-express-hack/
@stuck elbow I added a 2Mbyte flash in that one, the same ship as on the Express boards. I since swapped out the 2Mbyte flash on a feather M0 Express with an 8Mbyte version: https://daveastels.com/2017/10/15/feather-m0-express-supersizing/
idle owl
Sounds like a plan. Sorry we couldn't get it going! I was really hoping to. I messed up my own project by creating express without touch and had to wait to finish a guide until I added it. So I understand π
umbral dagger
@stuck elbow If you do your own bigger board, you pretty much have a feather. The Trinket hack was totally "hmm... I bet that would work..."
Python question/verification: not everythign results in a value, right? E.g I can't return the result of an if. Correct?
slender iron
@meager fog the older version I have is an SAMD51J20 and the new one is SAMD51J19
umbral dagger
the 19 has 512/192 and the 20 has 1024/256 I believe from my skim of the datasheet.
slender iron
yup yup
slender iron
@umbral dagger you can always swap it in
umbral dagger
Since they're both the J package, I assume the pinouts are identical.. would have to verify, though
slender iron
yeah, I think so
umbral dagger
That had occurred to me
Like... why settle for what's on the board if you have an iron & an SMT tip π
slender iron
@fading solstice
fading solstice
yes?
fading solstice
voice CircuitPython room?
fading solstice
ok
slender iron
then I'll have time and brain space
fading solstice
in 10
fading solstice
yeah
slender iron
@meager fog
tidal kiln
@umbral dagger just return the conditional
def foo(a):
# something that's like if a == 42
return a == 42
@tidal kiln Ah.. but it's not a boolean:
relative_humidity = si7021.relative_humidity
if relative_humidity < (target_humidity - 5):
return -1
elif relative_humidity > (target_humidity + 5):
return 1
else:
return 0
looks ok. what're you trying to do?
true coyote
I'll just be sitting here trying to decipher what this is doing.
Is this a trigger that activates depending on the humidity?
umbral dagger
@tidal kiln Oh, that works. Most languages I tend to use would let me put the return before the if and just have the values inside (if they even require an explicit return)
@tidal kiln Python is just close enough to what I'm used to, to make me feel like it should work the same way... but I always have the feeling that that's not quite right π
tidal kiln
return before if? how would you get to if statement?
do you have a code snippet that's like that?
umbral dagger
@tidal kiln Yes, in ruby I can do this (the return is implied... last value computed is automatically returned):
if x < 0
-1
elsif x > 0
1
else
0
end
end
floral dagger
you mean something like this? return x if c else y
umbral dagger
@floral dagger but with several cases, not just 2
tidal kiln
that'll only give two...
umbral dagger
@floral dagger but yes, that sort of thing. I saw that construct.. kinda cool
In Ruby, Lisp, Haskell everything results in a value, everything is an expression... you get used to it π
tidal kiln
@umbral dagger ok. haven't worked in those langs.
umbral dagger
Python is closer to C in that you have expressions and statements.
floral dagger
what about return -1 if x < 0 else 1 if x > 0 else 0
tidal kiln
yeah. can nest.
floral dagger
well heck. that's dumb :p
umbral dagger
One thing I have on my list of M4 projects is to do somethign like circuitpython but with a lisp instead of python (probably a stripped down Scheme... which I just happen to have 90% complete)
@floral dagger Huh.. ok, cool... but slightly confusing to read.
floral dagger
that just worked for me in the python tool
umbral dagger
@floral dagger That works fine in CP
floral dagger
although I had to make x lowercase twice.
umbral dagger
@floral dagger once that's fixed
@floral dagger Long var names makes it even more opaque. I'll stick with keeping it wordier but more obvious.
floral dagger
@umbral dagger awesome. You're right it is a little wonky to read.
umbral dagger
@floral dagger OK, I used that construct to simplify another function... to the point that having it a function was useless and I just inlined the line.
stuck elbow
@umbral dagger ah, so it was you who did it, thanks, it gave me an idea for using flash in my own board
cunning crypt
@floral dagger @umbral dagger This made me think that an example of coding for filesize vs coding "normally" could be useful. Especially for non-express boards
stuck elbow
@umbral dagger yeah, Python has separate statements and expressions, and you can't use a statement in an expression
umbral dagger
Early look: https://bitbucket.org/dastels/humdiity-alarm
stuck elbow
@umbral dagger you know that it has a real dac pin?
@umbral dagger if you are compiling your own firmware, you can enable the audioio module
and then have any sound you like
umbral dagger
@stuck elbow Ya, I know.
slender iron
no worries @river quest

is there a good example of using the accelerometer on CPX in CircuitPython w the adafruit_lis3dh library?
(was doing it w express.mpy before, but need to do w/o for now due to other conflict w sound playback)
slender iron
@split ocean the memory issue still?

@slender iron sweet!
slender iron
I record the weekly meetings if you want to listen afterwards. They are in posts that are pinned. (The pin icon at the top.)

@split ocean I figured send you everything I had on mine in that form to see if for some weird reason some other file you had was causing issues.

I realized by looking at your zip file that you didn't have a lib folder full of our bundle stuff. Oops.
idle owl
Oh yeah!
split ocean
I'm sure my memory error was just conflicts w all sorts of things

So much of it got frozen into the CPX 2.1 so it doesn't need to be in there
I was hoping sending that would clear things up!

idle owl
@stuck elbow That's fantastic!
stuck elbow
you can solder a paperclip to it and use it as a pin
cunning crypt
@stuck elbow I feel like it would be fantastic if the eye was a LED/neopixel, and the body layers (Neck, top, middle, bottom coils) were capacitive touch buttons
stuck elbow
@cunning crypt a neopixel would be more like the whole head
slender iron
apa102s are tiny

but I;m rather thinking about regular purple leds along the neck on the back side, to not spoil the graphic
cunning crypt
oooo

problem is, it's hard to lay it out on one layer
split ocean
@idle owl for purposes of the tutorial, is the express.mpy you sent me in that .zip file available to the public yet?
stuck elbow
I can share the Fritzing file
idle owl
@split ocean I'm going to try to get it tonight before the new bundle gets created. At the moment, no it's just with me, but I'll get a pull request in.

foreach??? In Python?
lofty topaz
https://learn.adafruit.com/adafruit-circuit-playground-express/circuitpython-built-ins
Go here, it indicates foreach as a flow control statement. Typo???
tulip sleet
@lofty topaz fixed - that was just someone writing late at night
lofty topaz
π thought so. ><>
Also, I'm a bit concerned that "array" is a built-in. Any reason why and do you have dictionaries yet?
slender iron
@lofty topaz python is all dictionaries
they are used internally and available as built-ins
lofty topaz
@slender iron Ok, great, the text on the website just indicates Tuple, Lists and Arrays.
tidal kiln
maybe just semantics? array being used in a general sense?
kind of like the term 'sequence'
lofty topaz
@slender iron Please don't missunderstand me. The tutorial on CPX is fabulous. Huge to say the least, growing as we speak and very helpful. It's just when I see things that aren't quite right I tend to say something. Kudo's to you and the staff on this project.
tidal kiln
no prob with dictionaries in cp:
>>> d = {'key':'val'}
>>> d['key']
'val'
>>>
@lofty topaz no worries. thats why I want to get us to a place where details like that can be easily adjusted
lofty topaz
@tidal kiln Great, Doc should reflect that. Dict. are a very important part of python. I my view anyway.
lofty topaz
I've been involved with micropython these days and will be switching over to CPX in the near future. That's why I'm getting educated on it with the webste.
tidal kiln
don't take whats (currently) there too strictly then, don't think if it's not mentioned it's not supported.
but good feedback for updating the guide
lofty topaz
@tidal kiln I know, it's like HTML, a living document. Not version controlled.
umbral dagger
@stuck elbow Cool board concept.
idle owl
On that same page it still says Trinket and Gemma don't have pulseio and sudioio support. Everything updates so quickly it's difficult to keep up!
formal plover

lofty topaz
@idle owl Which is why prying eyes like mine will say something so it can be updated.
idle owl
@lofty topaz There's also a feedback link on the left side towards the bottom where you can provide feedeback.
lofty topaz
@idle owl I just mentioned the 'foreach' and it got fixed in minutes. Refreshed the browser and walla, there's the fix.
idle owl
@lofty topaz Yep! We can't always get to it that quickly, but we listen!
lofty topaz
@idle owl Feedback??? Where??? Am I missing something???
@idle owl Oh, on the website page, yes, your right.
idle owl
There you go!
It's a good option because there's not always someone here who can fix it.

@slender iron the functions that are not in CircuitPython are surrounded by #if MICROPY_PY_MATH_SPECIAL_FUNCTIONS/#endif. concerning shared-bindings documentation.

@brisk cairn @tulip sleet might have one. I don't develop on windows so I don't
floral dagger
are the BAT and USB pins output only? The learn docs mention using them as power sources for connected devices, but doesn't mention if you can also use them to power the huzzah
idle owl
It blinks!!
solar whale
@floral dagger I load to a feather huzzah routninely, what is the problem you are haveing?
slender iron
@floral dagger I don't think so
floral dagger
@solar whale It just loads gibberish and gives fatal errors on boot. It was the same issue I had with the breakout, but resolved it by powering with a stronger 5v supply
solar whale
@floral dagger On the breakout I thought you were once using 3.3 v to power but USB to the Feather shouild eb 5V and plenty.
umbral dagger
@stuck elbow You can always grab a SAMDE54 Xplained board from Microchip/Digikey.
stuck elbow
or make my own
umbral dagger
yup
sick creek
make Circuitpython board what runs M4
solar whale
@floral dagger - did you erase the flash before loading 2.1
floral dagger
@solar whale Oh yeah, you're right. I forgot my adapter is 3.3...I was just thinking USB
solar whale
Thsi can be a bigger problem
floral dagger
yes. I've tried a powered USB hub as well
solar whale
I often get prblems if I don't erase
stuck elbow
@sick creek so far I made a m0 one, but can't get the display to work

@floral dagger that looks very noremal
sick creek
the former looks broken
floral dagger
it just keeps rebooting though
slender iron
@floral dagger this is on the same USB as your breakout had trouble?
cunning crypt
@floral dagger I've had that issue with Arduino on an ESP before. Putting not enough things in the main loop would just make it continually reboot
solar whale
the giggerish is completely normal -- preboot uses a lower baudrate
floral dagger
@slender iron I have it on a powered hub

OK - ampy won;t work if it can't get to REPL anyway

I don't want to eat up the channel. I'm going to keep throwing things at it to see what sticks. Thanks everyone. If you think of something, please let me know
solar whale
OK - I'll be home later and will try loading the same image.
@floral dagger one more silly question should. After load are to pressing reset button ?
floral dagger
yes, and between each step of erase/flash

I'm tempted to see if I wuld have better luck flashing it with my raspberry pi
tulip sleet
that would be a lot closer to what I'm doing. Do you have more than one?
marble talon
I hear people talking about CP on a Feather Huzzah but I don't recall hearing if it's supported on a Huzzah32?
tulip sleet
@marble talon - nope, sorry
marble talon
Figured as much, but I also hadn't seen anybody asking about it so wondered if I was the only one with a Huzzah32 π
floral dagger
@tulip sleet I just have the one, but I should be able to sus out the process. It can't be too dissimilar
tulip sleet
@slender iron are all the M4 builds are still using the internal flash fs? I'm merging in the latest 2.x changes and I had redone the logic for selecting the flash impl.

the chip on your board is an ESP-12S correct?
floral dagger
I think so, let me check
solar whale
this part https://www.adafruit.com/product/2821
solar whale
yup - thats it - very odd - tryin from Raspberry Pi or with version 2.1 esptool may be instructive...
I'm using linux box.
stuck elbow
@floral dagger sorry, I didn't follow from the beginning, but did you do eras_flash?
floral dagger
yes
stuck elbow
I noticed with older versions of esptool that it didn't always work the first time
erasing the flash, I mean
solar whale
given taht it erases and program OK then boots to first message, I don't thing the issue is in the programming.
try forcein flash_size to 32m instead of detect - after erase ofcourse π
floral dagger
tried esptool v2.1....same issue
slender iron
@tulip sleet did you build a bossac for linux yet? I have other builds here: https://github.com/adafruit/BOSSA/releases/tag/adafruit_17_10_19
solar whale
ok - If i build/install it is is backward compatible with older boards?
slender iron
yeah, I think so
formal plover
I'll try flashing 2.1 later @floral dagger and let you know if I have any problems
I use a Raspberry Pi to flash mine
solar whale
buil ok - any special setting s to flah m4?
tulip sleet
@slender iron @solar whale you mean bossac for M4? No, not yet. I wasn't sure I had a working bootloader to use yet. Been using gdb only.
solar whale
ok - so I can load to it via jlink - I'll try that.
slender iron
@solar whale no special setting. I think it detects automatically
@tulip sleet we have a working arduino "BOSSA" bootloader but not UF2
solar whale
hmmm ```

@solar whale jlink pins are the same
solar whale

lofty topaz
And CircuitPython with Circuit Playground Express is the product to use for it.
solar whale
same erro messages on Raspberry pi
tulip sleet
@solar whale I haven't had a chance to build the latest 3.0.0 at all. I'm merging in the latest 2.x changes to 3.0.0. The stuff above looks like the USB MSC commands are not working well. MSC uses a simplified SCSI command set.
@slender iron would have more to say
solar whale
Sometime REPL works and other times I can't connect
tulip sleet
he just finished the MSC implementation
quite possible ther are some bugs that might be corrupting memory - it's very early days for 3.0.0
pastel panther
@lofty topaz I think the idea is that CP is bigger than adafruit. Would linux be what it is if Linus insisted that there be a logo on every page?
tulip sleet
you might try a different USB port (maybe USB2 instead of USB3); the slower speed might help
formal plover
@idle owl too legitimate to quitimate
solar whale
I'm on a USB2 powered hub - I'll keep working with it. I was afraid it was an isue with Jlink, but it is not.
lofty topaz
@pastel panther And where is Linux today? On a Raspberry Pi? Why not everywhere? Because people didn't know about it. It has taken years for linux to take any kind of hold in the market. Now it's a toy. Big deal.
pastel panther
@lofty topaz I don't think linux's reach is limited by it's marketing, it's limited by the open source community's historical preference for features over documentation and ease of use
lofty topaz
yes, that too.
pastel panther
Also not everyone needs a sonic screwdriver
umbral dagger
@empty estuary I'll say this: Since Python got started (about 10 years after I started programming) CircuitPython is the first time I've found it interesting and useful enough to learn.
@lofty topaz Linux a toy? wut? Let me introduce you to my little friend: quad core 4GHz i7 with 64G ram & 1T M2 SSD. Running Ubuntu 17

pastel panther
(admittedly I started it)
tulip sleet
@solar whale if a hub, might try direct-connect; but I'm thinking it's just bugs. Is it erratic when you restart (mon reset; continue) in gdb?
umbral dagger
And it runs on my Pis. Same thing. which is very cool.
lofty topaz
@umbral dagger Right, and people want kids to use it? With command line interface? Com'on man. Embedded is the future. Operating Environments, not systems is the future for embedded. MicroPython is an Environment. And I like it.
umbral dagger
@lofty topaz Yes, and that's a huge reason it's so interesting!
solar whale
@tulip sleet I have npt gotten gdb up an runnig yet - will try later tonight or tomorrow.
slender iron
@solar whale I'm back now. I've only seen serial corruption during os.listdir() for some reason
the MSC sense is likely and asf4 problem we can fix
solar whale
when I connect jlink - curent goes up from 42mA to 103mA - is that normal
but JLINK is not connecting properly
solar whale
ah - I wonder if it is a power issue - 5V is OK?
sick creek
@slender iron omg you know that Rosie head looks similar to barrel
idle owl
I'm powering mine from USB as well. But I haven't hooked up the jlink yet.
slender iron
@solar whale my barrel might actually be 9v
solar whale
do you also use USB for REPL connection while powered via Barrel?
slender iron
yeah I do
I have a usb cable that can connect and disconnect the data lines without unplugging
idle owl
@slender iron You do all the j-link stuff on MacOS?
solar whale
I'm using Linux - may try MacOS next
slender iron
@idle owl yup
@solar whale should be essentially the same on linux
@solar whale that looks correct to me
solar whale
hmm - I have the USB port "turned off" but I guess it passes daat since I see USB drive - jlink now connected!
slender iron
how did you turn it off?

my hub has switches on each port

split ocean
@idle owl, did that guide thing work out for you?
idle owl
@split ocean I couldn't update one page. It worked out everywhere else for me though!
split ocean
If it's the code not updating in the guide after you've changed it in Git, I have a trick for that.
idle owl
No it was one page in the guide that refused to update. The code on Github is good to go.
split ocean
OK, sometimes Learn gets a little stuck.
idle owl
I couldn't add the embedded link and delete the inline code, it hung and refused to update.
split ocean
yes, sorry, that's frustrating
usually works a few minutes later.
Say, do you have time for another UFO question?

I'm so glad!
slender iron
@idle owl I love that you did PRs for the Key of Lime code

now, I want to know how feasible it is to play audio while still checking acclerometer and adjusting the colors of the NeoPixels. Currently I play the sounds and everthing else is on hold.
idle owl
@slender iron lol π
@split ocean We talked about this yesterday! As it is, no it's not possible, unfortunately. It's something we want to add to it, but it's not included right now.
split ocean
LOL, we did? Ha!
idle owl
@split ocean No I mean Scott and I did
idle owl
Nope! Not yet, anyway
split ocean
OK, no problem, I have what I need to make it fun
idle owl
I'm glad! Being able to do things at the same time is on the list, but as it was, it didn't work very well and allowed for a lot of weirdness with the sound. So we wanted to get that out first!
split ocean
I dig it. I may just play the sound under a particular condition, like a large change in the accel readings so it only plays sometimes, but most of the time it's quickly responsive colors
idle owl
Got ya!
sick creek
@split ocean perhaps you start to hack remote controlled air shark with Circuitpython

@idle owl you too! thanks for the help

fading solstice
quick release it. no testing needed
floral dagger
Just a quick update, it's looking like this is a hardware thing. My other ESP flashes fine. This one keeps geting wdt resets every few seconds as it tries to execute code no matter what I use to program it. It did the same thing in the arduino IDE when doing example sketches. It could do a simple serial.print and delay just fine, but anything more intensive just kicked it back to reset.
Anyway, just thought I'd update. Thanks again for the help.
idle owl
Thanks for the update! Sorry to hear it might be hardware...
cunning crypt
@floral dagger Given it's the ESP, I'm assuming you have nothing connected to any of the other pins?
I had a boatload of issues where stuff wasn't working because I had something weird hooked up to one of the boot pins
floral dagger
yeah, @cunning crypt just the bare feather hooked to a powered USB hub. Oh well, these things happen I guess
stuck elbow
@floral dagger I think you can get it replaced.
split ocean
@idle owl here's an alternate path of inquiry re: UFO sounds...
idle owl
@split ocean Yah?
split ocean
Limor mentioned that maybe play_tone would be a good choice
is that integrated in express already?
idle owl
Yep!
stuck elbow
theremin-like sounds would be great for UFO
split ocean
she said simpleio had it, but i would love to use it from express if that's there
idle owl
play_tone which asks for the frequency and a duration in seconds.
There's also start_tone and stop_tone which allow for things like the tone piano where it plays for the duration of a random-length trigger event like a button being pressed or touch pad being touched.
I'm not sure if it works the same as in simpleio though, I'd have to look
One of those should though
split ocean
yeah, i worry that if i have both libraries I could run into similar conflicts as before as far as pins being grabbed for speaker
OK, I'll try that, is there any usage example code you know of?
idle owl
Yep, there's the code on ReadTheDocs. Oh! And my guide! lol
split ocean
sweet!
idle owl
Checking it against simpleio now.
Hmm. Not finding any examples for how it works in simpleio.
How do you want to use it?
@split ocean https://learn.adafruit.com/circuit-playground-express-piano-in-the-key-of-lime/touch-tone#make-some-noise
Use tones to make the same noise as ufoup.wav?
split ocean
your guide looks great, I'll try playing around with that
idle owl
Thanks!!
split ocean
kewl
thx
I may get fancy and play that ufoUp.wav under some condition and tones the rest of the time
idle owl
Nice!
split ocean
but can do just tones if that gets outta hand
sick creek
I need to get some shark tunes
as circuitpython play shark tune when shark is closing or in the area
split ocean
du-Nuh du-Nuh du-na-du-na-du-na-du-na Du-Nah!

even the shark is mixed reality one and moving in wifi network area inside the house
or air shark with circuitpython controls
solar whale
@floral dagger thanks for the report. Sorry it sounds like HW but that does seem to be the simplest explanation.
true coyote
May I ask why we're comparing circular circuit boards to limes?
idle owl
It wasn't a comparison. It was a reference to a new learn guide. π
true coyote
And it somehow involves green, sweet versions of lemons?
cunning crypt
Looks like you've got a bit of lime buildup. You should look into some de-liming solutions

@solar whale FYI I'll be using the jlink stuuff on linux. I have it installed and connecting to my SAME54 board.

@solar whale Yeah, that would seem to be the best solution.... now do I have a spare outlet near enough for a wall wart?
solar whale
@silent radish good luck. Looking forward to playing with this board. I am new to JLink so much to learn.
formal plover
Mine will arrive after you guys figure everything out π
manic glacierBOT
solar whale
@formal plover no fear of that!
formal plover
Haha I'm only kidding. Mine is stuck in limbo right now. I'll help when it arrives
umbral dagger
@solar whale New to the jlink.. same.
formal plover
I have a jlink in with it as well
umbral dagger
I ordered a j-link earlier to use with the SAME54Xplained board, before being drafted/honoured... so I have the weekend to get up to speed. My Sunday was goign to be busy but that got moved to Monday.
It's a P20 chip... so maxed out memory and all the I/O π
@slender iron I'm looking at metro_m4_express/mpconfigboard.h ...it includes internal_flash.h as expected, but also has SPI_FLASH defines. Leftovers?
slender iron
@umbral dagger just hasn't been updated because we haven't added spi support
the board has spi flash, we just don't use it yet
umbral dagger
got it
hollow tartan
@slender iron Where are the adaFruit developer guides for Circuit Python?
slender iron
what are you looking for? the build guides may be under micropython still
hollow tartan
I don't know just generally what are the standards. Especially interested in SamD21 / D51
hollow tartan
I am reading a "Design" book by the chief of IBM os/360 and was looking for what AdaFruit Standards are set out , where, and how?
slender iron
I don't know what you mean by standards
hollow tartan
a link in CONTRIBUTING covers it. i think. https://github.com/micropython/micropython/wiki/ContributorGuidelines
How is it looking going forward for SamD51?
hollow tartan
Great! I have used TI Tiva C LaunchPad for developing in Keil uVision. So I have a little familiar with Arm Cortex M4 internals.
slender iron
awesome!
hollow tartan
Do you enjoy digging in the several thousand page tech. ref. for the SamD51?
slender iron
I do π
hollow tartan
What tools do you use to develop your code?
slender iron
arm gcc and atom
hollow tartan
you must be one of the top people in the field , I am honored to get to know you.
hollow tartan
That is a real inspiration. Best of Luck and Make IT Awesome. π
slender iron
thanks! let me know if you want to get into circuitpython dev. I'd be happy to help get you set up
hollow tartan
Yes, sir. I am dipping my toe in after a little while.
drowsy geyser
Wheeee! Got the Metro M4 Express today! Now trying to figure out how to get CP onto it. Got the JLink Mini updated and working (at least with the GDB server). Kind of fumbling along, but happy to be tinkering. I'm making a OneNote page with my notes, which I'll share if anyone is interested. They differ in subtle ways from LadyAda's M0 instructions....
Just a sanity check h ere. Is it true that I can't load the Metro M4 using the usual methods? It doesn't show up as a mass storage device, so I can't just drop the UF2 image onto it. But bossac doesn't find the device, either. I'd be a bit surprised if I have to build CP from source in order to install it....
solar whale
@drowsy geyser you need to update bossa https://github.com/adafruit/BOSSA/tree/adafruit_17_10_19. . Use the Arduino branch. I went through this a few hours ago π
drowsy geyser
Thank you!!!! I'll go do that now...
solar whale
Good luck!
If you scroll back about 12 hours you will see my fumbling intro to the M4.
drowsy geyser
Thanks, @solar whale . The Bossa update fails since I'm on Windows 10, not a Mac. I tried building from source, but that didn't work because of an include file error. I guess I'll try to figure out how to install it on Windows 10....
solar whale
Hmm. I was able to build it on a Linux box.
drowsy geyser
It's late. I'll sleep on it. π
drowsy geyser
Ok, I gave up on Windows. I connected the M4 to a Raspberry Pi, installed bossa latest from apt, then built the adafruit/bossa/arduino branch. When I run it, I get the "SAM-BA failed" error message. Yes, I put it in the bootloader. I do notice, though that as soon as I run bossac all four LEDs on the M4 come on solid (green, two amber, and red). I also tried running as root (no difference) and re-running bossac without touching the board (no difference). Any ideas?
Well that's interesting. If I run it without putting the board in the bootloader, I get a different error ("device unsupported")
Now trying different permutations of attempts. Still getting the "SAM-BA operation failed" message.
solar whale
@drowsy geyser I got the SAM-BA error when I built the wrong release of Bossa You should use the Arduino Branch, not Master.
@drowsy geyser never mind. I missed that you did build the correct one. Sorry.
drowsy geyser
No worries, @solar whale . π
umbral dagger
My weekend plans changed and so I am able to devote time to getting up to speed on jlink and M4. Goal is to be comfortable with it by Monday when the Metro shows up.
solar whale
Good luck - I am having mixed results - I often get itno a sitiuation where Jlink cannot communtcate with the board. Eventually I get it back, but I have not found a reproducible sequence yet.
umbral dagger
I started working on the board files for the SAME54Xplained board last night and am getting errors building CP during the gen phase. For any board.
That started happening after pulling the latest off master.
Iβm wondering if my GCC install got updated without me noticing.
That would be highly unlikely, and unlikely to have a breaking change like this.
solar whale
did you do the git submodule update --init --recursive to get all udates in place after pulling the master?
umbral dagger
OK. fresh clone from master, did the above. I get:
cc1: error: -Werror=lto-type-mismatch: no option -Wlto-type-mismatch
../py/mkrules.mk:79: recipe for target 'build-feather_m0_basic/genhdr/qstr.i.last' failed
make: *** [build-feather_m0_basic/genhdr/qstr.i.last] Error 1
make: *** Deleting file 'build-feather_m0_basic/genhdr/qstr.i.last'
where ... is many of that error.
I'm running ubuntu 17.04 and this worked fine with the early 2.0 release.
split ocean
@umbral dagger maybe it's because Halloween approaches, but when you say "fresh clone from master" I imagine a conversation between Igor and his pet cat in Dr. Frankenstein's laboratory. β
umbral dagger
@split ocean I like that
solar whale
one other suggestin - did you do make clean first?
umbral dagger
yes.
If I checkout the 2.x branch, it all works fine.
(building, and installing the resulting uf2 to, in this case, a feather_m0_express
solar whale
odd - works on ubuntu 16.04 for me
umbral dagger
gcc version?
solar whale
arm gcc 6.3.1
sick creek
if you have fall creators update in windows 10 if you want linux terminal you can install it from store so it kinda make it easier than go to enable WSL
umbral dagger
I'm running 6.3.0.... seems unlikely that such a minor bump would be responsible... but I'll update
@sick creek I don't use windows
sick creek
@split ocean you have Frankenstein Labaratory
umbral dagger
@solar whale OK.. I installed the lastest arm toolchain from the arm site... it's building master now
@solar whale And still builds a 2.x that works fine π
umbral dagger
Goal #1 for today is to get a PR in for my 8Mbyte featherM0
slender iron
@drowsy geyser did you get it going?
@umbral dagger I try to stay up to date with the latest arm gcc
drowsy geyser
@slender iron Nope. No matter what I try I get the SAM-BA operation failed error...
umbral dagger
@slender iron It's a good plan π
slender iron
@drowsy geyser are you building it yourself?
drowsy geyser
CP? No, I'm using the image from the AWS S3 location. Bossac? Yes, I built it off the Arduino branch of your GitHub repo.
slender iron
arduino from here: https://github.com/adafruit/BOSSA/releases/tag/adafruit_17_10_19 ?
drowsy geyser
Oops. Nope. Downloading now....
slender iron
yeah, if its my personal repo I make no promises
dean was the one who fixed up bossa
drowsy geyser
It's compiling now. We'll see how it goes. π
slender iron
π€
drowsy geyser
Interesting. Same failure.
slender iron
have you doubletapped to get into the bootloader?
idle owl
Hmm
drowsy geyser
@slender iron I moved back to Windows with the pre-compiled bossac and WIN! I have a running M4!
slender iron
π
drowsy geyser
Three hours to Formula 1 qualifying! Good amount of time to get some testing done!
sick creek
I have hockey
idle owl
@drowsy geyser Way to go!
drowsy geyser
@idle owl Scott gets the credit. π
idle owl
He had to help me a ton too. π
slender iron
yeah, bossa is a bit finnicky
I'm torn between working on my toaster oven and trying to wrap up the uf2 bootloader
I got it communicating and everything but the flash was wrong
sick creek
bossa toaster
drowsy geyser
The toaster oven would probably be more fun....
idle owl
Is anyone else running jlink on MacOS? Besides Scott
formal plover
@slender iron it'll be a nice break too
umbral dagger
@idle owl I'm running linux... might be a similar experience.
idle owl
@umbral dagger Did you install the Segger software pack or are you running it from commandline?
umbral dagger
Segger from cmd line
idle owl
Do I need to install the software pack first for the commandline tools to be there? Or are there packages for it
umbral dagger
They had .debs for ubuntu
idle owl
Hmm ok
slender iron
@idle owl I just download and install the pack off of their website
idle owl
@slender iron Ok thank you
solar whale
@slender iron I am definatley having issues with the master build - it works sometimes but eventually the USB system on my linux box stops recognizing either the metro_m4 or the Jlink. I also ran into some similar problems on a metro_m0 build (at least i think so) but if its the same USB stuff taht mya be why. I end up rebooting my host system an it is OK again for awhile. I 'm sorry I don't have a clear reprducible case. I won't be able do do much more today but I'll keep at it as I can
@drowsy geyser sorry - I think I gave you the wrong BOSSA link.
idle owl
Pretty sure I simply don't have the knowledge level to understand what to do with the j-link. I at least got the software installed, and I think I updated the firmware.
solar whale
@idle owl have you looked at this guide? https://learn.adafruit.com/debugging-the-samd21-with-gdb/setup?view=all also I have found the Ozone tool from Jlink to work well so far.
Do yo have the mini or the "full sized" version.
solar whale
@slender iron Do you have to enter bootloader when you want to download via the Jlink?
@idle owl have you gotten the cble attached correctly? not obvious how to attach to mini
idle owl
No idea, might be wrong. I assumed it attached so the cable pointed away from the USB end.
solar whale
actually no - not as I have it - the small tab goes away from the USB.
idle owl
So if I laid them flat, the cable would be running over the USB?
solar whale
yes
idle owl
Ok so I had that wrong π
solar whale
idle owl
Yeah that's how I have it now, thank you for the picture! Clears that right up.
I'm running through the software installation command line stuff in the guide
solar whale
Good luck!
stuck elbow
one day the manufacturers of those things will actually figure out what those small tabs are for
solar whale
teh metro_M4 and M0 express have keyed connectors - taht helps!
so does the bigger Jlink adapter board. j
idle owl
Right I'm seeing that. The little one just has pins.
umbral dagger
Based on my experience at Steelseries (not what we were doing) the general state of embedded dev seems pretty antiquated.
idle owl
Hmm I sort of got further...
umbral dagger
Communities/companies like Arduino & Adafruit are changing that.
stuck elbow
well, those programmers are really just generic stm32 boards
in fancy boxes
as soon as open source firmware for them matures, there will be no reason to charge $300 for them
solar whale
@idle owl as I look at it also make sure the red wire is on the same side as in my picture.
idle owl
It is
solar whale
ok - did you get gdb server to talk to connect to it?
I'm sorry - I will have to go offline in a fw minutes- wish I could stay to help - good luck
slender iron
Jerry you donβt need to be in the bootloader for the jlink to connect
idle owl
@solar whale Thank you for your help! I'll keep at it
solar whale
@slender iron even to download an image to it?
idle owl
@solar whale It's getting far enough along to tell me it can't halt the CPU, so I'm much further than I was.
slender iron
Nope. It works through the chip debug circuitry
slender iron
Not able to halt is a separate thing. I had to use a hacked arduino zero to recover mine. Do you have circuitpython on it @idle owl ?
idle owl
I do. It's still flashed from yesterday and blinky still works. I'm doing this because I wanted to learn more about the jlink.
solar whale
Sometimes it seemed like I could get out of that by entering boot loader. That is why I asked
idle owl
I'm not even sure what it does. I assumed I could get it to show me some data from the board.
slender iron
That can happen if pin states are changed or something. Usually if itβs working then Itβs ok.
stuck elbow
@slender iron how would I got about debugging an issue with the haxpress boards (trinket's mcu + flash) where it reboots into "safe mode"?
slender iron
@stuck elbow do you have a debugger? If so, you can break on the hardfault handler
stuck elbow
I only have the stlink working, the jlink clones I have refuse to work
not sure if stlink can debug over swd
umbral dagger
Slowly making prgress with jlink/gdb
tulip sleet
@umbral dagger I have a patch for the lto warning building master. Are you still having trouble?
It's very simple.
slender iron
I bet stlink would work @stuck elbow
stuck elbow
I need to try
umbral dagger
@tulip sleet I'm good. Upgrading to the latest GCC toolchain from ARM fixed all my troubles.
Taking a break from jlink and working on a writeup for the DotStar FeatherWing CircuitPython library I wrote.
Which naturally means I realize there are useful features it's missing π
formal plover
I want to port the Arduino midi note library eventually. So you can have little simple songs play from a piezo. Similar to the notes used in the guide @idle owl's key of lime guide.
stuck elbow
isn't that just a bunch of constants for the frequencies?
formal plover
@stuck elbow basically. Like this note equals this frequency
idle owl
Yep
formal plover
And then play a c d d etcetera etcetera
stuck elbow
have you seen https://github.com/adafruit/Adafruit_CircuitPython_RTTTL ?
