sorry @idle owl! had to break for dinner and Gotham... and that was the link. 😄
idle owl
fixed it. ugh. Had no localhost.

and doing what Scott said to earlier.
and purple LED.
unless it's still doing things.
oh it might be.
onyx hinge
@timber mango thanks for the hint about 'vim -n' earlier!
idle owl
Ok so I unplugged USB, and did all the GDB stuff, and I have a green LED
Does GDB eventually stop Continuing. ?
I'm not sure when I can try plugging it back into USB
raven canopy
@idle owl plug what back into USB? the jlink or the metro?
raven canopy
did you unplug the swd cable?
idle owl
no
it was still "continuing" on gdbs end, and JLink was Received monitor command: reset Resetting target Starting target CPU...
So I wasn't sure I could
raven canopy
try unplugging the swd cable, plugging into usb, then reconnecting the swd.
idle owl
Ok I have a green LED but nothing is really happening.
raven canopy
where did gdb end up?
idle owl
LED on JLink is a little bit blinky
Continuing.
Program received signal SIGTRAP, Trace/breakpoint trap.

@slender iron UPS delayed my package - stuck in CT. Should be here tomorrow.
@raven canopy I do have a Beagle, but I tend to like using Wireshark and usbmon on Linux better. The Beagle software is limited in what it will decode unless you pay more.
idle owl
Even a new build is a purple LED.
raven canopy
@tulip sleet hmm...maybe i should find a possible equivalent setup on Win10. prob doesn't exist... you all get a ton of snow?
idle owl
Is gdb supposed to do something after Continuing. ?
tulip sleet
You can use USBPcap on Windows and Wireshark. Be careful, because there was a bug when upgrading WinPcap through the Wireshark installer - you could lose all USB devices. I think that's fixed but I had to use the PS/2 port on my older computer and a PS/2 keyboard adapter to recover.
idle owl
I hit reset and got blasted with errors again.
tulip sleet
we got a sprinkling of snow. I was head down on HID all day and took a break this evening.
raven canopy
oh joy. i don't have a ps/2 adapter, and new mobo is 100% usb. i'll do some diligent reading though.
idle owl
pushes a table a couple of inches to the left without much enthusiasm
raven canopy
@idle owl 😄 reminds me of the "two inches to left" episode of That 70's Show.
idle owl
I don't remember that, heh.
It was an alternative to a table flip since I'm kind of doing this to myself.
tulip sleet
Make sure you use the latest version.
Beagle 12 software only decodes descriptor packets, not regular USB packets (like characters). Scott adapted a converter from Beagle CSV export to Wireshark: https://github.com/tannewt/python-pcapng
raven canopy
disclaimer comments are the best: "Most likely this is fixed in 1.2.0.3."
idle owl
"I mean we probably fixed it."
raven canopy
although, at this point with the diversity in systems...it can be hard to say "tis fixed, guaranteed!".
idle owl
Ok giving up on that I guess.
raven canopy
still just getting purple?
idle owl
Yes.
Even with different order of operations with everything. It eventually ends with purple.
raven canopy
trying to get the libs on?
raven canopy
ahhh. well, purple is....hardfault yes?
idle owl
When I first tried, I got CIRCUITPY.
I loaded a code.py, I managed to get some of the libs on.
purple since then.
raven canopy
if you weren't getting purple, i would say that the bootloader was toast. is the code.py still on there?
idle owl
no idea.
raven canopy
wait...you can't answer that.
idle owl
Scott said he thinks it might be the bootloader. Earlier.
raven canopy
sorry. brain left the building for a second.
idle owl
Nah it's all good
I could have easily missed something
Would the flash eraser work? Or would that be a terrible idea.
raven canopy
??? haven't used or looked at it. i'm not sure what all it touches.
is the jlink connecting ok?
idle owl
Yah sounds like a terrible idea.
Yep
or at least as far as I knew
I put it away already
Before I really did need a tableflip.
raven canopy
the table thanks you.
languid sage
@idle owl this won't help your problem, but it may put a smile on your face. Many years ago, while working in SW development @ Motorola, we (engineering) realized that sometimes things get broken, and we called them bugs. The folks on the 2nd floor (marketing) would look at the same issue, and decide to tell the customer how wonderful it was, and therefore it became a feature. Then we realized that often, features were truely broken, so we called them beachers (buggy feature), and a real feature that was broken, we called a fug. Not sure why the industry didn't adopt these terms, but we sure got some weird looks at lunch at the Sizzler (common ground for Apple engineers). So, I ask you, is a purple LED a beacher or a fug? :^)
idle owl
😄 Good question.
languid sage
I know it is late in your part of the world, and thought a smile might help
raven canopy
haha. can it be a beacher fug?
languid sage
now you're not an engineer or marketeer... but in accounting.
raven canopy
answered to perfection! 😄
languid sage
actually, once I had a junior engineer fix a bug. we told him exactly where to look, and what to fix. before the "fix" was committed, we checked it out. he made the exact change we requested in the wrong piece of code. so I guess beacher fug, or worse can exist.
idle owl
So I grabbed the still borked CPXs from the other night, installed 2.2.3 and then upgraded to 2.2.4 and they're both fine. Blergh. Ok.
raven canopy
@tulip sleet Microsoft actually has an analyzer: Microsoft Message Analyzer. don't have anything to compare it to, but i've recorded a couple traces. filtered down to our IdVendor number...reports all transfers as successful. some of the values are odd (requested IN xfer length: 4096), however.
was not expecting you to be up... 😄
tulip sleet
@raven canopy I have tried to use that in the past, but had trouble filtering the output and went back to wireshark (which I was familiar with from network traces). However, it looked like it was pretty good - not sure it parsed all descriptors I wanted. But good you got it to work.
I have been having trouble with HID and am dubious about the USB stack - having trouble with various things. ... Yes, I should go to bed.
raven canopy
ASF4...thanks for the callback structure and all of that documentation. 😬
tulip sleet
the callback stuff is awful. There seem to be layered instances of the HID devices. I couldn't get the HID callbacks to work, but not sure what is wrong. Also the hid generic interface is only a singleton - not sure what they were thinking, since the idea of a generic might be to have multiple devices.
idle owl
Oi.
raven canopy
i'm beginning to think that they designed each driver as a standalone, without thinking that anyone might use multiples. callbacks would be great if all we were doing was a USB stick and could just set-n-forget.
timber mango
Could the Trinket M0 work with a USB type c instead of micro USB
idle owl
As in removing the connector and soldering something else? Or using an adapter?
raven canopy
@idle owl RE: CPXes magically working. The universe realized it had you running circles on something else, and implemented the "mah bad" clause. 😄
idle owl
@timber mango I use a USBA to USBC adapter all the time, but I don't know if you could simply replace the connector on the board with a USBC socket and have it work. I'm not sure what's involved with that.
@raven canopy Apparently. Ugh.
timber mango
Hmm
idle owl
Someone else probably knows better than I do, but that's the best I have for you for now.
timber mango
afaik they're all electrically identical; just different form factors to work with smaller chassis.
Once USB 3.x comes into it, that changes abruptly -- and a few other weird things that are listed in this article:
https://en.wikipedia.org/wiki/USB#Connector_types
@timber mango so, no. The table shows USB Micro-B receptacle (Trinket M0) only mates with a USB Micro-B plug. If it's a molded plug (or cable-end receptacle) you won't find a commercial means to do it wrong (you'd have to craft your own, and understand the wiring).
In any case, Trinket M0 (and all related targets) have four wires (D+ D- +5V power and ground).
Presumably if your PC is a USB-C host, there's a way to connect older equipment to it.
quote:
Type-A and Type-B adaptors and cables are required for older devices to plug into Type-C hosts.

errant grail
@Mochi#2000 @timber mango Sorry, but I may have passed over a critical factor of USB-C. The data protocols are different. Although I don't know for certain, the Trinket's USB interface circuitry and bootloader are probably not compatible, regardless of however creative the DIY electrical connection. The driver software on the host computer is likely not compatible, as well. Perhaps a USB-C to USB-A/B hub would be needed to throttle and parse the data transfer protocols, but without the appropriate custom driver on the host end, it probably wouldn't work well. Stick to USB 2.0 for now is my advice.
slender iron
@errant grail actually USC type C is independent of USB 3.0. You can use USB 2.0 over type C just fine with the right resistors hooked up to a couple of the new 3.0 lines
raven canopy
@slender iron you won't believe this...REPL is fixed (I think...still gotta run some more tests).
slender iron
amazing!
raven canopy
usb_bytes_available was the problem...
slender iron
huh
raven canopy
bool usb_bytes_available(void) {
if (cdc_enabled() && !pending_read) {
start_read();
}
if (usb_rx_count == 0) {
return false;
}
return usb_rx_count > 0;
}
it was ALWAYS calling cdc_enabled, which would clear the buffer...
bool usb_bytes_available(void) {
if (usb_rx_count > 0) {
return usb_rx_count > 0;
}
if (cdc_enabled() && !pending_read) {
start_read();
}
if (usb_rx_count == 0) {
return false;
}
return usb_rx_count > 0;
}
ah! that makes sense
raven canopy
i'll probably change it to if (usb_rx_count > 64)...but, i've got upto 160chars printing.
slender iron
only read more if we have nothing buffered

slender iron
yeah, asf4 will do that to you. especially the usb stack
raven canopy

Hi Everyone, just joined the board.
I'm building a 18 key chording keyboard using an atsamd21e18, and I've built a modified UF2 bootloader (still awaiting my j-link to flash).
I was hoping to make a modified Trinket M0 circuitpython firmware (single LED, no NeoPixel), but when I build the files I get an error due to a missing module adafruit_usb_descriptor file. Pretty new to Micro/CircuitPython, so any help would be appreciated.
I'm using Mint 18 32-bit build environment running in VirtualBox, and cloned the adafruit/circuitpython repo.
Just thought to search... Doh!
I got past the adafruit_usb_discriptor issue, but now I get the following repeated many times one invoking make:
cc1: error: -Werror=lto-type-mismatch: no option -Wlto-type-mismatch
Looks like a compiler issue.
raven canopy
@jovial pine which compiler and version are you using?
jovial pine
How would I check? The bootloader built using arm-none-eabi-gcc, but I don't get any information out of the make command for circuitpython.
make V=2 states arm-none-eabi-gcc
stuck elbow
arm-none-eabi-gcc --version
jovial pine
4.9.3
jovial pine
I was messing with an old build guide for something else...
jovial pine
I'll look at updating the compiler to be a more recent build
raven canopy
@jovial pine there was a very recent update for this situation. see here if you need some assistance: https://github.com/adafruit/circuitpython/tree/master/ports/atmel-samd#setup

Anyone here know for sure if audioio is only on the Express boards? @idle owl and I were looking at this and seems like that's the case -- I was trying to use adafruit_rtttl library on Gemma M0, but looks like that's not currently possible. @slender iron
onyx hinge
@jovial pine I can help you with that one. If you have an older gcc version you can safely delete those lines. They work around a bug/limitation in newer versions of gcc.
I compile circuitypthon successfully with gcc 5.4 on debian stretch, the flag is needed with 7.2 (but the project recommends using gcc 7.2 on ubuntu as described in ports/atsamd/README.md)
stuck elbow
@split ocean it's only on express boards, but I have compiled custom firmware for the trinket with it enabled (I had to disable analogio to make room)
split ocean
OK, thanks @stuck elbow I'm doing this for a learn guide, so I'll keep it to pwm tone instead.
stuck elbow
I think someone was working on a version of the rttl library that used pwm, but I can't recall the details
onyx hinge
@jovial pine that is, you can fix the build problem by finding the -Wno-error=lto-something lines in ports/atsamd/Makefile and just deleting them
slender iron
@split ocean I'd like to make RTTTL use pwm as a fallback if it doesn't already
split ocean
that would be a cool option to have
it currently fails on a GemmaM0 when it tries to import audioio
this is on 2.2.4 btw
split ocean
great, thanks.
slender iron

jovial pine
@jepler thanks for all the help. Make is doing the business...
onyx hinge
@tulip sleet proper long support would be nice
.. my trinket m0 doesn't have much space left though!
tulip sleet
@onyx hinge it would make sending 32-bit values to devices a lot easier
onyx hinge
aha found both places to enable mpz longs. 75% of the remaining flash in trinket m0 ends up used to implement it. eek! (and my board's not here, have to wait to try it later)
raven canopy
yeah. it gets tight on non-express boards..

@raven canopy just put together a trellis board and tried your driver - worked great! Very nice!
onyx hinge
@raven canopy So e.g., the ItsyBitsy M0 Express will have more growing room?
solar whale
@onyx hinge If I am not mistaken, the difference is that the express boards don't have to hold back flash space for the internal FS -- the non-express boards hold 64K for the FS.
gemma_m0
#define BOARD_FLASH_SIZE (0x00040000 - 0x2000 - 0x010000)

There's a good diagram of USB-C plug on page 4 (Fig. 3) that shows how D- and D+ are only on one side of the reversible connector. @timber mango @errant grail -- USB-C must implement USB 2.0 connection (1.2.1 on page 2).
The datasheet for SAMD21 says it implements USB 2.1 as both host and device.

2.4 Passive Cables
A passive USB Type-C cable does not have embedded powered electronics. All passive cables must minimally support USB2.0, and it can support USB Power Delivery up to 60W of power.

2.7 USB Type-C to Legacy USB Cables
The USB Type-C™ specification also defines the allowable USB Type-C to Legacy USB cable assemblies. The following full cable assemblies are supported:
(yadda yadda)
USB Type-C to Micro-B (USB2.0) << smoking gun
Fig. 4 shows VCONN and CC. Everything else about the plug (right-hand drawing) side of this figure is explainable by understanding USB 2.0.
@onyx hinge You could just wire A6 to B6 and A7 to B7 at the USB-C receptacle.
A6 (D+) on the plug mates with either A6 or B6 on the receptacle (depending on if it is in the flipped or proper orientation -- plugs in either way and 'just works' wow!)
Similarly, A7 (D-) on the plug mates with either A7 or B7 at the receptacle.
slender iron
@split ocean do you have a pending guide I can look up for hoook up instructions?

@solar whale I can't take much credit on the Trellis library. ladyada and TonyD wrote its parents, and tannewt suggested all of the subsequent changes... but, glad you like it!

slender iron
errant grail
If mpy_cross is included in the REPL, would it become possible to have an option for import to convert to mpy from within the code itself?
slender iron
yeah, not sure if that would save memory though
errant grail
It might with some of my verbose custom libraries. 😉
slender iron
if other imports happened before it then it'd still have less memory
errant grail
Got it. Would be better to replace the .py library with an .mpy version to begin with.
slender iron
yup, think so
at least having it available built in then you don't need to worry about finding a mpy-cross for your platform
errant grail
yes, a nice feature indeed.
BTW, stringcar CPy motor controller algorithms are done and are calculating string length very accurately during bench testing, but it's too windy today for the on-the-string tests.

@slender iron HID mystery solved: After a buffer is sent, the buffer gets cleared somehow by the USB code or peripheral. So if I copy the data too early, while the previous transaction is in progress, then the data I want to send will get zero'd out. I have to copy it when the endpoint is ready to send and not before (or recopy it on each attempt).

@restive pasture unfortunately I never commited it, but the modification is trivial — just moving some lines in the mpconfigport.h

Moving on to the project to convert the Corrosion Monitor from Arduino to CPy tonight. After a bunch of searching, standing on one foot, and holding my tongue on the right side of my mouth, was able to get the ili9341 drivers to work with the 2.7" TFT FeatherWing driven by a Feather M0 Bluefruit disguised as an M0 Basic.

Is there a CircuitPython library for the Adafruit Ethernet FeathrWing?
I am guessing making a CFFI wrapper around the Arduino based library would be out of the question due to all the Arduino library files it requires.
onyx hinge
@analog drift a few moments of searching didn't find one yet.
analog drift
Yea. I am probably going to have to translate the Ethernet2 library written in Arduino to CircuitPython
raven canopy
@onyx hinge microcontroller.cpu.temperature is all commented out for now, and returning 0. I assume it'll be re-enabled after all of the mappings (ADC, etc) are done in 3.x. https://github.com/adafruit/circuitpython/blob/master/ports/atmel-samd/common-hal/microcontroller/Processor.c#L193
@analog drift as you've determined, there isn't a library yet for the Ethernet wing. If you do end up making the library, please feel free to contribute it! This guide will help you with how our standard libraries are made: https://learn.adafruit.com/creating-and-sharing-a-circuitpython-library/overview

@raven canopy Thanks
raven canopy
@analog drift also, if you do follow that guide, don't set it up as a "Community Bundle" library. I imagine the CircuitPython folks at Adafruit would want to put it in the Featherwing library in the Adafruit Bundle: https://github.com/adafruit/Adafruit_CircuitPython_FeatherWing/tree/6d498560a8af32bacf2ff358c3751a6a85a2e5ff I'll put in an issue for the library, ask the question, and see if we can get you an adafruit github repo created.

Hm, setting the filesystem label from python on the trinket turns out to be a bit tricky.

Is there a document describing the design of hash() in CircuitPython / MicroPython? It seems to not be a "very good" hash function, but I assume it's based on trade-offs that I'm not aware of
for instance, hash("...") seems to always fit within 8 bits, and hash(float) is just floor(float) unless it's "too big"; then it's -1
timber mango
i think its just for dictionary lookup speedup
onyx hinge
#if MICROPY_QSTR_BYTES_IN_HASH == 1
#define Q_HASH_MASK (0xff)
timber mango
do you need a 'true' hash function?
onyx hinge
looks like yes, string hashes are just 1 byte for compact storage of QSTRs
@timber mango I was looking at autogenerating a device label based on microcontroller.cpu.uid
timber mango
ooh ok, i know uhashlib works well - https://github.com/adafruit/Adafruit_Learning_System_Guides/blob/master/CircuitPy_OTP/main.py
kinda overkill tho
onyx hinge
Agreed. It looks like it's excluded on my Trinket M0 due to space constraints anyhow
timber mango
im a fan of just grabbing the last 4 digits in HEX
and appending, we do that with MAC addr's on BLE boards
onyx hinge
That's the last 16 bits of the microcontroller.cpu.uid?
timber mango
yeah
raven canopy
that's what the ESP8266 does as well.
onyx hinge
These numbers don't look all that random, sadly.>>> [hex(i) for i in struct.unpack("!8h", microcontroller.cpu.uid)]
['0xb05', '0xf00', '0xe0e', '0xd01', '0x0', '0x1', '0x500', '0x10f']
the datasheet remarks at one point that you have to use "all 128 bits" to be guaranteed a unique number; it looks like maybe they even structured the ACTUAL uids so as to catch anybody who didn't follow it
timber mango
could take a classic CRC-16?
onyx hinge
something simple like that sounds good, yeah
onyx hinge
_crc16(microcontroller.cpu.uid)
1550
sure could work, at least it's a calculation that involves all 128 bits
onyx hinge
so, yes, both of the hash() suboptimal behaviors I saw are deliberate trade-offs in micropython.

Well, 32kb RAM.
You could add a seed value (salt) and store it, so that it can be regenerated again later, to add pseudo-bits of entropy. ;)
who's going to have both present -- a near-serial number, and a (pseudo) random seed value stored, on two different entities?
Then just concatenate and CRC-16 from there.

@meager fog the kids saw the word "spy" and took off with it 😉
@meager fog @tannewet and a feather M4 w/perhaps a CS4334 DAC on it would do 85% of what stuff out there does now.
timber mango
yayy! did you see the schem for the m4 boards?
ruby lake
not yet
timber mango
sent in PM 😃 take a look!
ruby lake
grabbing now
timber mango
metro m4 is pretty much 'done' but feather m4 is still up for changes 😃
that said, its never too late to make tweaks
i think id rather make a featherwing with i2s on it, maybe with one of our nice i2s chipsets
in particular, im diggin' the AK4954AEN Audio CODEC
$1.25 by the reel
cunning crypt
That sounds like a reel-y good price.
ruby lake
reading the codec datasheet
timber mango
thats normal/standard, it uses a PLL
M0 does the same. the 32khz xtal does double duty as PLL input to 48MHz as well as low power clock
timber mango
(that said, iirc its broken in first silicon rev of M4, we use USB timing and internal trim data)
stuck elbow
so something like the trinket m0 does?
stuck elbow
I'm thinking about µGame with SAMD51, and I will probably skip the crystal on it too
(no need for exact timings)
hmm, I think the revB had an inductor connected to the m4?
looks like a big capacitor
or is that the L1?
ruby lake
plenty of space on feather for D+/D- pogo pads
timber mango
there is an inductor there, its for the built in 1.8V buck
@ruby lake oh yeah ill add em
stuck elbow
but that's not L1 on this schematic?
it's connected to a separate chip
ooh, I see, you have the chip broken up into sections
that's neat
timber mango
yah, for simplified schematic
stuck elbow
is an eagle noob
timber mango
this software isnt famous for its excellent UI
ruby lake
that codec has an impressive set of tools for the inputs
ruby lake
samd port and pin config has to be one of the most headache-inducing things I've ever read
timber mango
I thought Silabs C8051F3xx series crossbar was challenging enough. ;)
timber mango
@ruby lake the sercoms are particularly annoying, but other periphs are not as bad
ruby lake
@meager fog I finally found what I was looking for, that being which pins can be MLCK. (table 6-18)
pastel panther
hey @meager fog You wouldn't happen to have a part number for the inductor on the m4 would you? I found one in a 1210 package that I've used so far in my m4 board but I'm having trouble finding one with the proper saturation current and ESR as specified in the datasheet in a smaller 10xx package like you used on the m4 metro. I'm hoping to shrink the board even more so any spare mm² will come in handy

i really need to find a way to put the correct bootloader back onto my debug trinket. using the feather hex "works", but i can't get to trinketboot anymore. 😄

@raven canopy cant you use the .bin file from the released versions of https://github.com/adafruit/uf2-samd21 or build it yourself from this repository?

@solar whale i was looking into that last night. will most likely give it a go. thanks!
@solar whale worked like a charm. why didn't i scroll down on the releases page last night? hehe
analog drift
Does circuit python support .mpy files?
raven canopy
@analog drift it does. although i'm not sure that they're interchangeable with micropython .mpy files.
analog drift
That's fine. I do not need interchangeability between circuit python based .mpy files.
raven canopy
👍 just wanted to make the note, in case.
analog drift
Nor integration with existing .mpy files
Yea, but that is really need that .mpy files are supported given the limit space.
And is there a way to compile C based libraries to be exposed to CircuitPython? Similarly to the C-API bindings or the CFFI library?
raven canopy
well, all of the core libraries (digitalio, audioio, busio, struct, etc) are written in C. Look at the circuitpython/shared-bindings and circuitpython/ports/???/common-hal to see how they're implemented. but, as deshipu said, we're not able to run C from circuitpython. it is a desired thing though...
analog drift
@raven canopy I'm guessing all of those libraries are build into the interpreter itself?
raven canopy
yes
@analog drift if you look at the Makefile for each port, you'll see where they get included into the compile.
<-- is clearly on first cup of coffee; can't form complete sentences yet. 😄

@slender iron let me know if I should file more of these. I have two additional crashes found by afl-fuzz in circuitpython so far. All of the crashes I've discovered today seem to be unique to circuitpython and are not in micropython.
raven canopy
@onyx hinge I would hold off for now. to my knowledge, we don't maintain the unix port at all so that first issue won't be all that bothersome. as for sockets, the only port we maintain that I recall using it is the ESP8266. we keep those ports in the repo so that we can stay up to date with major upstream pulls...
onyx hinge
@raven canopy Point taken. As far as I know, though, ports/unix is used (tested) by the travis setup and is actually pretty useful when it comes to developing non-hardware-interfacing code
onyx hinge
@raven canopy thanks for the encouragement to test on an actual circuitpython board. I can't test the 'usocket' one, but only one of the rest produce the same crash.
though .. this is pretty weird
a1 = array.array('O', [1])
a2 = array.array('I', [2]) * 2
a3 = (a1 + a2)
print(a3)
array('O', [1, inf, inf])
array('O', [<trinket hangs>```ooh nice catch @onyx hinge !
raven canopy
nice catch indeed. my bitwise game is...not that good. 😄
onyx hinge
argh, pressing "restart build" on travis destroys the evidence—it discards all the old build logs, and re-does build #NNN rather than starting a new build #MMM with the same branch/ref
onyx hinge
.. a failure in thread/thread_lock3.py on unix that occurred just once on a commit touching nothing even vaguely related ☹

@onyx hinge If you surround code with one backtick on either side (in the upper left of a US keyboard, on the same key as the tilde, and next to the 1), you get inline code, if you surround it with three backticks on either side, you get a code blockMakes it easier to read code 😃

@idle owl I'll try to remember that
idle owl
It took me a while to figure it out, but now it's so much a habit I find myself doing it in places where it's not supported 😄
onyx hinge
@idle owl I just wish my tilde-markup from github came through properly, since I seem to be writing lots of code on issue comments today
idle owl
@onyx hinge It should work the same way, with one backtick on either side. Is it not?
onyx hinge
ah, hm, do backticks work there as well?

@prime flower Morse Code resources: http://www.arrl.org/learning-morse-code Learning to receive is much harder than learning to send. For sending, using a straight key and a code practice oscillator are fine.
Key to learning is not to learn visually, but aurally. Receiving is like muscle memory. Having an extra mental step of converting dits and dahs into a visual image of dots and dashes and then the letter will slow you down.

@solar whale Looking.
Hmm... I don't know either. I think I've tried something like this before and had issues, but that doesn't mean it doesn't work, that simply means I don't know how to do it.
It's something in the syntax, it has to be

That’s where I am too. I think the poster is missing something but I’m not sure what. Seems like they have some experience with python so I’m not sure what to suggest.
idle owl
I've made that assumption about people and been wrong before, their knowledge may not necessarily apply to this issue. I would suggest having them try to simplify things, put the function in main.py or something, make sure it even works... I don't really know either. But start with something working first and then try to complicate it.
solar whale
I’ll ask them to post their code and go from there. Thanks!

Thank you for helping them!

one bit of help might be to point them to this: https://learn.adafruit.com/welcome-to-circuitpython/creating-and-editing-code#naming-your-program-file
ask to see demo.py, not sure why import demo and demo.tester() didn't work
thin badge
hey all... is there a reference somewhere for what properties are on the 'board' object, specifically for gemma M0?
tidal kiln
@thin badge can just do dir(board) at REPL
thin badge
... <grumble> I wish I was smart enough to know what you meant... Im literally doing "vi main.py" (because Im a dinosaur)
(although google helps)
😉
tidal kiln
yah, google probably helped with the acronym. but check here:
https://learn.adafruit.com/welcome-to-circuitpython/the-repl
thin badge
<nods> thanks... Im there... 😃
thin badge
👍
I have to say... you folks / this community is one of the most (if not the most) friendly, helpful, and knowledgeable community I've ever stumbled upon. Thank you for being you
tidal kiln
when you get to REPL, try this:
Adafruit CircuitPython 2.2.4 on 2018-03-07; Adafruit Gemma M0 with samd21e18
>>> import board
>>> dir(board)
['A1', 'D2', 'RX', 'SCL', 'A2', 'D0', 'TX', 'SDA', 'A0', 'D1', 'L', 'D13', 'APA102_MOSI', 'APA102_SCK']
>>>
hopefully that's what you are after. i don't think we have anything that documents this for each board (that i know of). it varies from board to board. but you can do this with any of them.
thin badge
yeah... basically setting up a "blink" example and what I thought should blink (pin lable D1 / ~A1) is actually blinking the onboard led (Gemma M0)
*label
tidal kiln
the on board LED in on D13, which is only routed internally and not available on any of the pads
do you have an external LED attached to D1?
thin badge
I have a small neopixel strip attacted to D1/~A1 which I had working via arduino / C but now I want to learn circuit python (that Im not under a time crunch for a hallowwen costume) 😉
and yeah... mu seems to be a lot nicer than the arduino editor...

main.py output:
Traceback (most recent call last):
File "main.py", line 5, in <module>
ImportError: no module named 'neopixel'
while I understand that lack of a library shouldn't be why Im seeing blinks on the embedded LED, this should be something I need to track down, right?
idle owl
@thin badge If you surround a bit of code with one backtick on either side (the one in the upper left of a US keyboard, on the tilde key, next to the 1), you get inline code and if you surround code with three backticks on either side, you get a codeblock
It can make it easier to read code snippets 😃
thin badge
just like slack... 😃
tidal kiln
yep. you need the neopixel library if you're going to work with neopixels.
they aren't like regular standalone LEDs
that same guide covers libraries: https://learn.adafruit.com/welcome-to-circuitpython/circuitpython-libraries
thin badge
ok... so not embedded by default in circuit python... Is this a situation where I install it into my python install and... or I could read the "fine" manual... <hangs head in shame>
tidal kiln
when you read the guide, keep in mind you have a "non-express" board with the gemma m0
thin badge
thank you... Im certain that would have been a future question... 😉
tidal kiln
and this could help as well in case you haven't found it yet:
https://learn.adafruit.com/adafruit-gemma-m0/circuitpython-neopixel-2
although that guide has a circuit diagram with the pixels attached to D1/A0, but the code uses board.A1 ?? hmmmmm.....
idle owl
Oops. Good catch.
thin badge
YES. that is exactly what Im looking for!
idle owl
@tidal kiln Can you look at the NeoPixel page again please? I updated the diagram
tidal kiln
@idle owl looks like correct pin. where'd the green squares on the pads come from?
tidal kiln
yah. that was my guess.
thin badge
weird oddity though... I went through this... thing where mu must have used the gemma as a location to store temp files or something and whenever I started it, it would fill up the gemma drive with images / sounds / etc... started it with the gemma off and all was fine.
raven canopy
@thin badge its a known problem with Mu. they're working on getting it taken care of

This'll give me a good starting point. Going to try to port a variant of the "cosmic turtle" necklace over to circuit python... Should keep me busy for a bit.
yes, alien
@tidal kiln ^^
thank you all for helping me get off the crazy bus.
tidal kiln
fixed. but will be in next release:
https://github.com/mu-editor/mu/issues/358
thin badge
ok... one last question, only to satisfy my EE ignorance... When I crack out 'ye olde multimeter' and I measure DC voltage on ground & Vout, I get something in the 4-4.5 range (expected) but when I measure ground and D1, I have to flip the meter to AC voltage because the "signal wire" communicates with AC, right?
tidal kiln
even in AC mode, you won't get any meaningful measurement on the data line with a multimeter
you'd need a oscope or a logic analyzer to see what's going on
thin badge
I mean, I see the values 'pulsing' (for lack of a better term) between 0 and 185micro volts. (I think thats what the greek letter mu means, right?)
it just tells me that there's voltage "there" not what it's actually doing...
(and an oscope is a bit out of my price range unfortunately)
tidal kiln
you'll see some indication of activity, but it doesn't really tell you much. it's a very fast digital signal.
thin badge
<nods> but it was something that wasn't there before... 😉
ok... back to my cave... thank you AGAIN collective hive-mind. You're the best!
tidal kiln
i guess it can tell you something is happening vs. something is not happening
errant grail
@thin badge some multimeters have a "frequency / duty cycle" mode that can be helpful in detecting pulse activity on a pin. On the EXTECH meter it's called Hz%.

i hate to admit it, but i have no idea what i'm doing
period
i haven't even gotten to coding anything, i'm having trouble getting mu even properly set up i think

@onyx hinge I know of two keyboards running circuitpython
tidal kiln
@unreal ginkgo what OS are you using?
onyx hinge
@slender iron links please!
unreal ginkgo
windows 10
onyx hinge
@slender iron that looks great!
@slender iron I'l take one when you go into production
slender iron
that won't be happening any time soon. I'm happy to show you how to make one though
unreal ginkgo
either i can't find the way to launch it with what the install came with
or the .exe i downloaded from codewith doesn't let me use adafruit stuff
sick creek
@slender iron you could even make a Adafruit feather powered PC cooling
tidal kiln
@unreal ginkgo what happened when you ran the .exe that got downloaded?
unreal ginkgo
just automatically went to the microbit one and there was nothing in the corner that i could interact with to change it
tidal kiln
so it at least ran?
unreal ginkgo
yeah
tidal kiln
just didn't show any adafruit releated options?
unreal ginkgo
not a one

@unreal ginkgo I installed mu_2018-02-21_15_12_master_2a33437_32bit.exe on Windows 10 and it asked me on launch to select between Adafruit and the other modes. The download link I used is here: https://learn.adafruit.com/welcome-to-circuitpython?view=all#installing-mu-for-windows-or-mac-os-x
onyx hinge
@raven canopy @slender iron thanks for that fix!
unreal ginkgo
Yeah, that’s the thing
I couldn’t figure with what I installed where to launch from
I had to get something to launch with from a separate site
tulip sleet
@unreal ginkgo It just showed up in my Start Menu as "mu", and I clicked that. So sounds like you were running the old version using the other thing.
it is under "M" in the Start Menu and also showed up at the top as "recently installed"
unreal ginkgo
Alright thanks
tulip sleet
see you later if you have trouble
solar whale
@raven canopy Tried the latest CP 3.0 master with your REPL fix on feather_m0_express and metro_m4_express_revb -- works great!

thanks for your testing @solar whale. wouldn't have been as great without it. 😄
onyx hinge
oh why did I say to myself "I can probably duplicate the core functionality of numpy in a day or two"? (not related to circuitpython, but related to python..) 💩
"it'll be easy, I'll just use boost::python and boost::ublas" and now I have a single, 550 line file that takes as long to build as circuitpython does for trinket_m0

I don't think it actually has "." entries
onyx hinge
I bet you're right
unreal ginkgo
maybe i just didn't read the answer to this when it was right in my face
but all i can seem to get this to do is the basic stuff for code.py
there's probably just something in my face that i'm completely misunderstanding
but i'm slowly kinda sorta figuring it out?
all i've got lit up is the green led and the red led that i can kinda sometimes make blink like that one thing showed how
unreal ginkgo
i'll be honest i have almost no grasp on coding
raven canopy
@unreal ginkgo nothing wrong with that! we all started at zero... 😄 Which board do you have?
unreal ginkgo
finally got my circuit playground express today
raven canopy
ok. I was kind of hoping it was a CPX. You could try starting with Microsoft MakeCode for the CPX. It's a web-based visual, "block" based system which is designed to teach things like program structure and flow. It actually a pretty robust system. https://makecode.adafruit.com/
Then, once you're comfortable, you can come back to CircuitPython with a little more knowledge. Just a sugestion. Python, and CircuitPython we hope, is fairly easy to learn compared to other languages...
unreal ginkgo
i was using that but i wasn't sure how to use IR remotes or add in custom assets
i have most of what i made in there, it's simply starting off with getting used to how things work that's got me confused
raven canopy
Ahhh. Good deal. Yeah, there are some things like IR that aren't quite available in MakeCode (yet?).
unreal ginkgo
yeah, i have most of the extra sounds i'll be using as well, just kinda not sure where to start off with all this in general
i can get the red light to blink, and that's about it
raven canopy
are you following any specific guide?
unreal ginkgo
okay then
i guess the guide i was using wasn't exactly working
huh
tried using the remote control ornament with a non-adafruit remote
it got the red light to light up when hitting buttons but no other lights
raven canopy
ok. i was just looking at that guide. did you read the codes that your remote is sending, and update your program?
this will help you with reading the codes that your remote will send for each button. https://learn.adafruit.com/ir-sensor/circuitpython
unreal ginkgo
i think it's from the fact i'm using just some remote i found in a box
raven canopy
yeah. you'll need to re-map the code to respond to your remote. the code in the guide is specific to the adafruit remote.
raven canopy
not necessary; you just have to do a little work/learning to use what you have on-hand. win/win if you ask me. 😄
unreal ginkgo
i understand what you're saying and i agree
it's just a pretty old and probably almost a foot long remote, and wouldn't really be practical in the long run
well, back to uh
whatever i was doing
raven canopy
hehe. good luck! we're here most of the time if you hit any more speed bumps.
unreal ginkgo
thank you!
onyx hinge
wahoo, ripping out support for nonstandard array('O') and related items frees up 368 bytes flash over here and fixes several crashes you could get by using it
hopefully I understood properly what @tulip sleet was requesting, and that travis likes my branch...!
raven canopy
All Hail Lord Travis! 👑 😝
unreal ginkgo
honestly
all i need to do until i get a remote is figure out how to convert this into python stuff
just 4 or 5 simple things
i think it's more of the like
putting in what colors things will be and then using those things later on that's gonna have me the most confused
im the kind of person that will sift through the tutorials, looking for that one thing i need, and mess with it to my own liking, i'll just take help along the way
proven laurel
havent played with circuit python too much yet...thinking of sewing some LEDS into an overwatch hoodie of mine and getting some lucio sound files from the game to play at the push of a button..is this something that circuit python can handle?

What's the easiest way to build a V2.2.4 for a new board (Trinket based)?
I tried the vagrant instructions but it builds V3...
tulip sleet
@onyx hinge you understand me perfectly! thanks!
@jovial pine checkout the 2.x branch
onyx hinge
https://emergent.unpythonic.net/01522108310 I wrote a little blog post about using afl-fuzz on circuitpython.
unreal ginkgo
hhhhuh
do any of the tutorials for circuitpython involve the A or B buttons?
tidal kiln
@unreal ginkgo for the CircuitPlayground Express?
unreal ginkgo
yeah
tidal kiln
hmmm. there this little example here:

there's a lot of the stuff that i see, and miss a ton of stuff while browsing

@onyx hinge I'll add that for the newsletter next week!

Is there a way to get REPL in Atom editor
slender iron
Not easily. I usually just have it in a separate window
glad rapids
OK
glad rapids
If you wanted to hook Circuit Playground express to network can you use ESP8266
unreal ginkgo
basically making it flash real fast
sorry for all the questions, but hey, i guess it's learning?
if the answer was staring me in my face i'll be amazed, lets try
onyx hinge
thanks for helping me get another PR to the point it could be merged @tulip sleet
slender iron
@stuck elbow have you looked at pygame zero at all?
anyone want to try and replicate this? https://forums.adafruit.com/viewtopic.php?f=60&t=133109
solar whale
@slender iron I don't have the DS1x280, but I can try with some other sensors. I have the same display and I expect this is the problem. - Might it help just to add a gc.collect() in the loop?
I'll try it this evening if I can get to it.
slender iron
@solar whale perhaps. I was also guessing that there is a bytearray thats allocated every change and then transmitted. instead, it could be created once and then updated
thanks @solar whale !
tidal kiln
@slender iron @solar whale i happen to have all that hw. i'll take a look.
tidal kiln
....and running. there's a ~5min delay in the program. crashing after 10-30 minutes is only 2-6 passes through the loop.
tidal kiln
well, i've exceeded their reported 30 min max run time. still no issues. so can't recreate.
stuck elbow
@slender iron I did, briefly, when Daniel just started on it
tidal kiln
i'm going to take out the delays and start it over.
solar whale
@tidal kiln good luck - hard to debug an irreproducible error. .... I wonder if it is worth monitoring gc.mem_free() as it is executing to see if it varies wildly. I have a similar test using an OLED and the free memory clearly cycles.
stuck elbow
I have written a bunch of oled drivers for mp that avoid memory allocation alltogether
could be ported easily, especially the spi ones
but the ht16k33 driver I wrote a long time ago, and I didn't care about such details back then
solar whale
It would be nice to reduce the ht16k33 footprint since I have found it hard to use on an M0 with sensors. Run out of memory pretty fast.
stuck elbow
the font data takes up a lot of space, being stored as a dict of tuples
could be stored as a single bytestring instead, that would be much smaller
solar whale
It will be a good learning experience - I'll be happy to dig into it.
tidal kiln
@slender iron @solar whale so far, can't replicate the issue. i've asked for version info in case that matters.
slender iron
thanks @tidal kiln

Which branch do I compile for V2.2.4? I've successfully built and installed a custom UF2 bootloader, and can build the V3 beta, but need USB_HID which I gather requires V2. I'm unsure which branch to select for V2.2.4. I need to do a custom pin assignment for my OneHand keyboard.
solar whale
@jovial pine - just do ```git checkout 2.x
make -C mpy-cross
cd atmel_samd
make BOARD=<yourboard> clean
make BOARD =<yourboard>
Thanks I'll give it a whirl.
solar whale
you need to rebuild mpy-cross then build the board. in 2.x there is not "ports" folder.
jovial pine
The branches I tried kept giving compile errors on the board make.
solar whale
what board are you building for
tulip sleet
don't forget git submodule update --init --recursive [FIXED]
solar whale
oops - sorry!
jovial pine
I was trying the default zero.
solar whale
isn't it git submodule update --init --recursive ?
tulip sleet
oops yes
jovial pine
CircuitPyhon is a fantastic system, but I've been more bare metal up til now.
unreal ginkgo
hhhhhuh
it's always hard to figure out ~if~ how something is gonna work when you dont have that something
solar whale
@jovial pine so after checkout of 2.x do the git submodule update --init --recursive then it "should" make...
