I just created an i2c object on my device, and hit "i2c.", and then tab. The lock function shows up attached to the i2c device
slender iron
yeah, you can do it manually but most drivers use I2CBusDevice and context managers to handle locking

@timber lion and @slender iron Maybe monitor the LiPo 3.7v input and detect when a clean shutdown is needed?
Ack! Quite a hack!
I'll go order the RGBW ring now....

@idle owl here's the mega demo for circuit playground express.. still a couple things I'm tweaking so i kinda consider it beta right now and will put on github soon after tweaking a few small things. check the readme inside it, i link to a video I made of the older arduino version that shows the usage: https://www.dropbox.com/s/8kpev2269cfnnoc/CircuitPlayground_CircuitPython_Mega_Demo.zip?dl=0
each demo is a class inside mega.py
and the VUMeter class is where I have start tone and stop tone
idle owl
@timber lion Thank you! I'll check it out now
@drowsy geyser Adding the bpp=4 to the Trinket demo code causes it to not light up at all. Adding bpp=4 to my own quick test code, and it works.
timber lion
yeah you probably have a RGBW strip or circle then
and on trinket it's a dotstar I believe, so only RGB
idle owl
@timber lion It definitely is RGBW. I knew that and it made sense once you nentioned it, but it didn't occur to me before that π
timber lion
oh no worries, yep i've made that mistake a lot π
idle owl
I got the demo working! Ended up doing a full flash erase and reinstall, and I needed to copy one library on, but now it works.

Hi @timber lion , I tested your mega demo. You may have forgot to mention that there is an "on/off" switch and nothing will take place if it is on the "other" position.
idle owl
@half sedge He still has a lot he plans to do - I don't think he intended to release it yet, that was something he did quickly so I had the code to work with it. That's a really good note though. Thanks!

@slender iron The recording turned out really well even with the background noise. Nicely done!

Hi, is there a table somewhere that compare Circuit Python board. Something that tell the number of pin, type of pin (breadboard friendly/sew-me), build in hardware, soldered power option, unsoldered power option, Express (or not), storage size, ...
I have a few of those board, but there seems to be missing a "buyer guide" that would help picking the right one.
drowsy geyser
@half sedge There are a few introductory guides that have some of this information, but I'm working on creating a master table to help people select the correct boards.
half sedge
Nice that you are working on that... so I don't have to do it. π
Here are some "criteria" I was looking for: Express/Not Express /// Breadboard/Croco /// number of pin (maybe there is a list of pin on the M0 and knowing wich one are exposed is interesting) /// powering option is maybe important such as is there a jst connector, or can you solder one /// storage (but it seems to be the same info as express or not /// UF2 or not is very important to know if it is a legacy board or a new board
Time to sleep in my timezone, it is now tomorrow. See you and goodby/night.

Good night!
sand bloom
Just caught up on the weekly. As soon as I get home from maker fair I'll get the project setup on my laptop and try to look at some of the stuff that was mentioned in the weekly. What would you guys recommend looking at first?
slender iron
Good question @sand bloom ! Do any of the beginner friendly tasks jump out at you?
idle owl
@sand bloom Hi! Exactly what @slender iron said! I was going to suggest checking the issues listed on Github and pick something that interests you.
sick creek
@slender iron now with Azure ML Workbench make use circuitpython more as @timber lion made the a video using Circuitpython board with jupyter notebook
sand bloom
@slender iron @idle owl I'm thinking a driver for the TCS34725 RGB Sensor
slender iron
@sand bloom that would be awesome! just check the bundle for any driver first
idle owl
@sand bloom Nice!
sand bloom
@slender iron will do!
formal plover
Thanks for getting involved @sand bloom! 
sand bloom
@formal plover I'm super excited!
formal plover
@sand bloom Yay! I'm excited for you!
What boards do you have that support CircuitPython?
sand bloom
@formal plover I have a Gemma and a trinket
formal plover
@sand bloom Nice! Two small form factor boards, double the fun.
The Trinket and the Gemma are going to be super popular.
idle owl
@sand bloom That's great!
sand bloom
@formal plover I agree! You can stick those things anywhere and sometimes you don't need all of those I/Os
@idle owl should I get anything else?
idle owl
@sand bloom It sounds like you're already off to a great start. Those two boards have tons of options. And you've got that sensor you want to do the driver for. I find that if I have a place to start, it leads to me knowing what other things I want to get. I had no idea when I first started. π
sand bloom
@idle owl Yay! I still need to order the sensor but it looked interesting to me when I saw it.
idle owl
@sand bloom Oh! Right, ok. Do you have a breadboard, or alligator clips?
See this is what I mean, the more we talk it out, the more I think of.
hollow tartan
O K PUTTY is officially making me crazy. I have a very simple terminal program called TexasDisplay. It works with REPL nicely. I have flashed 3 new NodeMCU esp8266 with micropython and they all behave the same. I get the boot blurb and >>> but the win7 and win 10 putty term just locks up.!!!
sand bloom
@idle owl Yup! I've got those sorts of things. I guess I should order a neopixel or some sort of rgb led and the sensor.
idle owl
@sand bloom Excellent! You're definitely off to a great start.
sand bloom
@idle owl Yay! Thanks for the encouraging words!
idle owl
@sand bloom You're welcome! Make sure to keep us updated. And we're always here for questions. I'm really excited for you!
formal plover
@sand bloom I just realized you made those Wi-Fi Deauthing Sandals
That's awesome! Such a cool project. And uses my favorite.. The ESP8266.
sand bloom
@idle owl Will do
@formal plover Haha yeah I did make those! I too love the esp8266. It's a really neat board
floral dagger
@hollow tartan does ampy work?
hollow tartan
@floral dagger don't know, have not tried it yet. ESPlorer is a mess too, as far as I know.
floral dagger
@sand bloom Hi. I think the best thing I got for prototyping is a pack of screw in terminal blocks that fit on th breadboard. It makes dealing with things like motors that have two loose leads so much easier
@haughty harness are you flashing nodemcu or circuit python?
lol I just atted the wrong person
hollow tartan
@hollow tartan is flashing micropython onto NodeMCU ESP8266. Orig post corrected for failure to spec.
floral dagger
Ah, ok. How do you have the ESP powered?
hollow tartan
Powered from Desktop PC USB in both terminal cases: 1. TexasDisplay, 2. PuTTY
floral dagger
@hollow tartan What you are getting sounds like an issue I was having. For some reason the board would flash, but the filesystem was weird on it. Sometimes it would start up, but no boot. Using a separate power source fixed that for me
by not boot, I mean run or install boot.py...sometimes it would, but it would freeze.
hollow tartan
@floral dagger what exactly is your other power source?
floral dagger
Right now I'm using a small breadboard power supply. I also used a 4AA battery pack for a bit.
but my board is 5v tolerant on the power pin
A powered USB hub may work too
hollow tartan
sometimes that power flux is a lack of Capacitance on the board itself.
formal plover
or power bun lol
floral dagger
lol @formal plover
I think, for my case, the USB port just didn't have enough gumption to power the board well enough. It may be worth a try if you have something you could use
that may not be your problem though. I dunno. It just sounds familiar
hollow tartan
yes, I have some BB 5V/3.3V supplies.
formal plover
@hollow tartan Did you do an erase first?
hollow tartan
@formal plover Yes, no slouching on the erase.
import os
os.listdir()
os.remove("file_name")
formal plover
@hollow tartan What are you using to flash?
hollow tartan
I am using esptool at the Windows Admin command prompt.
formal plover
Not this one @hollow tartan? https://github.com/espressif/esptool/
hollow tartan
N'est-ce pas?
hollow tartan
you got me, I still don't know why it is funny. Power Bun. ?
formal plover
@hollow tartan, @floral dagger were troubleshooting the other day and he said power bun instead of power hub. Sorry, somewhat an inside joke
hollow tartan
ah ha.!
floral dagger
lol yeah, was on my phone and autocorrect got me

@hollow tartan fantastic!

@slender iron I know at some point I saw a datasheet type thing for the CPX, but I can't find it now. Is it still posted somewhere? I'm trying to figure out what libraries I need to request - I think it might just be the lisd3h, but I don't know whether there's specific model numbers for any of the other chips and sensors.
slender iron
@idle owl you should be able to base it on your imports instead
idle owl
@slender iron Ok, good to know. That's what I had started to do, but I was trying to think ahead to the sensors I haven't written code for yet.
slender iron
I can't think of any separate ICs.
doing it by import will make more sense from the inclusion standpoint anyway
idle owl
Excellent, thank you

@floral dagger That's really neat! @formal plover has the ESP board, but he can't do any testing until after work.
sand bloom
@floral dagger I have one, but it isn't flashed for micropython yet. Let me try flashing it now and then I can see if it works.
floral dagger
Oh cool @sand bloom let me know how it works! I am using circuit python on my board. I'm not sure how much of a difference that will make. I don't think I used any CP specific calls

@slender iron You are correct. However, the Trivia Quiz has been slightly modified. Do you want to change your answer?
umbral dagger
Spending tonight playing around in CP with the new dotstar featherwing.
floral dagger
Sounds good @formal plover There's really not a whole lot in it at the moment. It's just activating a couple of pins, and allows you to switch between them. I'm probably going to fool with it some more. I'd like to expand on it some to make it more robust, but not sure which direction togo yet.
formal plover
I can probably use the simple http webserver learn guide to display the status of the pins as they change as well @floral dagger

@formal plover that most likely would work. If you have the serial repl open, it shows all the input and output going back and forth as well
formal plover
Ah OK, that's cool too!
floral dagger
As many times as I've seen that, and I never even really paid a whole lot of attention to it

Do you have a larger project in mind for that?
umbral dagger
@floral dagger No, nothing bigger in mind. Just having some fun. I've been digging into the feather ecosystem, and this board looked cool so I got one. Then found no real support or docs. So I started exploring π
floral dagger
awesome!
hollow tartan
@umbral dagger 8x8 led arrays come in two different configurations, row common cathode and row common anode. My question is does the feather wing only work with one of the types or is the software able to accomodate both on the 16k33 chip?
umbral dagger
@hollow tartan Not a clue π
@hollow tartan Well.. looking at the wing front on, with the reset button at the left, LED 0 is at the top right. It scans left fromt there. LED 12 is on the second roe, far right. It carries on from there, for all 6 rows. LED 71 is at the bottom left.
That's using the adafruit_dotstar module.
umbral dagger
@hollow tartan Thinking about this. This wing is dotstars that have a clock and data signal daisy chained through all 72 elements (conceptually similar to neopixels). I.e. they aren't a matrix; they're a linear chain.
@hollow tartan Sorry, it's been a kind of rough day... it took a while to grok exactly what you were asking.
cunning seal
@slender iron any udpates on porting the micro:bit speech to Circuitpython ? thx

@slender iron We figured out the NeoPixel issue, so you can leave that one out.
@slender iron Well you were there for that anyway. I verified the issue.
slender iron
yup yup, will look at the cplay docs
idle owl
@slender iron I think it's probably some missing space or blank line in the formatting of the new API we added. That's my guess anyway.
idle owl
I looked at the formatting in my API again, and it's not exactly the same as the others.
That's why I suspected that first.

@vague monolith I believe either will work. I have been using main myself.
vague monolith
As have I, I also found an easy way to corrupt the main.py file blanking it out. Not sure yet if it's a filesystem bug or circuitpython related.
tulip sleet
@vague monolith It's not hard to corrupt the filesystem, especially on Windows. After you write a file, do an "Eject" or "Safe Removal". Otherwise it can take up to 90 seconds for all the changes to be written to CIRCUITPY.
floral dagger
vague monolith
floral dagger
Sorry. Other way around
tulip sleet
@vague monolith Linux also delays writes to the filesystem, though not for as long as Windows. On Linux, just type sync after you edit or copy a file, and it will write out the rest of the changes. In general, don't press the reset button or unplug/plug if you can help it.
vague monolith
@tulip sleet , I'm aware of sync just didn't have time to pin down the source of the issue as it only happened twice. I'll mess with it more, if I notice it again.
tulip sleet
It's a nuisance. We are thinking of adding helpers to some editors to make sure the filesystem is sync'd after a write to CIRCUITPY.
It is hard or impossible from the CircuitPython side to know when the writes are all done.
vague monolith
@tulip sleet , I don't think it's a sync issue since the unit is being reset automagically by whatever is monitoring the file system. It occurs when i'm monitoring the serial connection(screen), editing files and letting it auto reboot. It hangs randomly, and that's when the issue occurs. Like I say I didn't have time to repeat it. I'll see if I get more time if I can trace it down.
tulip sleet
@vague monolith The problem is that some of the data is written, but not all of it. In general the file data is written promptly, but the metadata that says which blocks in the filesystem are in use is written 10-20 seconds later. So CPy sees a change to a file, waits 500mscs, and then auto-reloads. But if the metadata is delayed, then it will read a broken file. If you wait a few tens of seconds, you will see it auto-reload again. For instance, if a file is one block long, and then becomes two blocks long, the new file data will be there, but the filesystem will think it's only one block long until the later metadata is written.
vague monolith
Makes sense and sounds like what I was experiencing with the multiple blocks.
idle owl
My friend just left, she's so excited! I'm so proud of her! She picked up on MakeCode quick. She's going to come over again tomorrow or the next day to keep learning, and she can't wait to get home and play with it some more tonight. She loves her CPX. So excited for her!

@slender iron Maybe we should fix the neopixel library now and include it instead of waiting for Jerry?
slender iron
haha, thats the other option
tulip sleet
Go ahead and fix it. I don't think he'll mind!
tulip sleet
We can approve the pull request and then fix it up.

tulip sleet
@slender iron I can do neopixel if you want to make a release
slender iron
nah, I'll wait
tulip sleet
okee
slender iron
fixing the audioio crash would be good too

tulip sleet
@slender iron That stuff is high priority. I fell asleep at my desk after writing that last email, which is highly unusual, so I may not get to it today, but it's first on the agenda for tomorrow.
slender iron
kk. sleep is top priority!
tulip sleet
There is a stable branch in adafruit/circuitpython. Did you make that? We made a 2.x, but maybe it should be stable instead? I'm thinking about the .travis.yml file in the libraries which uses the stable branch to build mpy-cross. I'm not thinking so clearly.

is it wise to be doing USB hacking right before show and tell?
my usb webcam could be a casualty
sick creek
control your webcam using circuitpython
tulip sleet
@idle owl Scott uses Mac natively as a build environment; he installs what he needs using brew. I'm not familiar with that. You could also make an Ubuntu VM with VirtualBox, and it's not hard to get a build environment going there. Or you follow Tony's guide for vagrant: https://learn.adafruit.com/micropython-for-samd21/build-firmware. @slender iron could also just drop you a pre-built Mac mpy-cross. Maybe we should put Linux and Mac versions of mpy-cross in the release ...
idle owl
@tulip sleet I need to take a different route with what I'm doing anyway for this particular problem. However, this was something I was wondering about previously as well.
@tulip sleet That's the guide I saw about it too. It was more than I wanted to do for the issue I was having at the time.
sick creek
@tulip sleet homebrew on mac?
tulip sleet
@idle owl I started with vagrant on Windows but ran into a bunch of issues. I run Ubuntu VM's and native machines all the time, so that was easier to get going. Right now I develop on a native Ubuntu machine (the machine is dual-boot with Windows and has two SSD's, one for each). And I have an assortment of old and new laptops and other machines with Ubuntu and Windows. Just ping me sometime if/when you're ready to try something.
sick creek
@idle owl it was on AML Workbench what needed to do before using it was homebrew
idle owl
@sick creek I only found out about it in the last few months.
sick creek
in Windows you need just download and install using it from msi but in mac need to download 3 files i think and homebrew before install it
before using machine learning as write python and control your circuitpython board
idle owl
Yeah I installed it once I started using Python for the first time. It was for a RaspberryPi camera project I started.
sick creek
so multistep process
idle owl
I think it was, but it wasn't difficult. Just a few things and then I had brew.

@slender iron Just rough docs for now. I'll give some thought to making it better and/or more complete.
slender iron
sounds good!
umbral dagger
@slender iron Are there author guidelines anywhere?
umbral dagger
@slender iron Sounds good.
slender iron
thanks @umbral dagger
tulip sleet
@slender iron I'm gonna rename branch 2.x to stable, if that's OK by you. When master 3.0.0 is done, we'll advance stable to that. Etc.
tulip sleet
wouldn't we have to keep both up-to-date by merges, commits, etc, or can I add a name to a branch?
slender iron
yeah, thats a good point
tulip sleet
it's easy to rename: https://gist.github.com/niqdev/a327c3d8d24ddbd7584c
doesn't seem like you can give a branch a second name. I was worried that stable was a micropython-ism, but it looks like you created that name
tulip sleet
I was provoked to do this by the .travis.yml files in the libraries that want the latest released version, and by the stable branch in the readthedocs. But I like 2.x in readthedocs better, kind of like how the CPython docs have pathnames with the version. Maybe stable or whatever could be a moving-target tag name. I can study up on this some more and see what other people do.
slender iron
or we add logic to parse all of the tags for the #.x pattern
tulip sleet
Could do that, but having a fixed name for latest-release makes it easy. I'll read up and report back on other people's use cases. It's not urgent to change now.
slender iron
ok thanks!
drowsy geyser
Oh, good heavens, it's a pain to write a NMEA parser from scratch!
(Context: CircuitPython Ulitmate GPS driver.)
opal elk
@drowsy geyser can you copy/steal from an arduino implementation?
it seems like it's mostly a regex parser, though maybe import re doesn't work
tidal kiln
@drowsy geyser what @ Sigafoos said
https://github.com/adafruit/Adafruit_GPS/blob/master/Adafruit_GPS.cpp#L33
but also i'd think python would let you make it more pythony
marble talon
Ok, so I mentioned this the other day but now I have some new info, so maybe someone can help? I have a Feather M0 Express and I was doing CircuitPython and ran into some limitations (no NeopixelDMA) so decided to try Arduino IDE. I was working on my program and had it semi-working when I saw the drive unmount pop-up and Arduino IDE lost track of the port (as did OS X, El Capitan). No combination of board resets and mac restarts is getting the board recognized. I can boot it into FEATHERBOOT mode and drop a new uf2 file on it but if I eject it immediately pops back up as FEATHERBOOT. I've tried it on my other other laptop which I just upgraded with High Sierra as well as a Linux box with CentOS. Same deal. So, how can I get my board back in a useable state? The USB circuitry is working or it wouldn't show up as FEATHERBOOT but I can't get it to show up as a flash drive.
idle owl
@marble talon Did you try the flash eraser uf2 bfore loading a new uf2?
marble talon
@idle owl No, tell me about that?
idle owl
Download the right one from here:
Doubletap to get into FEATHERBOOT. Drop that on. It should do some blue lights, and then green I think, and then you doubletap again to get it back to FEATHERBOOT, and then load a new uf2 firmware or code file onto it
It will erase everything though.
marble talon
Strangely, it's been going right into FEATHERBOOT without the double tap.
idle owl
I seem to remember thinking you had data on there you wanted to keep.
marble talon
Yeah, I didn't want to lose my code but don't have a choice. That's the problem with editing in place!
idle owl
It's true... I manage to remember to keep backing it up 90% of the time, and then it's always when I get in the zone on the hardest of the code that I forget and lose the most difficult part I wrote. I totally understand.
marble talon
I should have made a copy when I switched to Arduino anyway. I'm not entirely certain how the Express knows which code to run?
idle owl
It runs code.py, code.txt, main.py, and main.txt by default on booting up.
So you edit those files locally (but be sure to backup! .. oi.) and it alters the code live.
Or rather runs the altered code on save, etc.
If you're in the serial REPL, you'll see it reload every time you save, and then run the new code immediately.
Wait. No that's what CircuitPython does. I'm not sure how Arduino knows....
I misread what you were asking, heh.
I need to run for a half hour or so. I'll be back after that.
marble talon
Yeah, I was wondering how it picked between Arduino code and CircuitPython code.
Doesn't look like erase is working--neopixel never turns blue...
@idle owl Hey, so it's not showing up as a flash drive but my port is back, so I'm back in business with Arduino IDE... Β―(γ)/Β―
slender iron
@marble talon arduino code replaces the circuitpython core. the file system on express boards should be preserved because its on separate flash
you won't get a CIRCUITPY drive if you load an arduino sketch on it because it replaces circuitpython which provides the CIRCUITPY drive
drowsy geyser
@opal elk and @tidal kiln Starting from scratch allows me to use a more Pythonic approach than would scavenging C++ code! For example, I can use a dict to map GP codes (e.g., GPGAA) in the NMEA sentences to funcitons, then execute the functions dynamically.
tidal kiln
yep
drowsy geyser
@opal elk The identifiers do, yes. They are GP followed by a three letter identifier.
opal elk
okay, that makes it much easier
drowsy geyser
Yes it does! π
opal elk
though I guess for i in range(len(sentence)): if not sentence[i].isnumeric() return i isn't too hard either
I'm mostly a 2.7 person so using range() over xrange() is still a little weird
idle owl
@marble talon I'm glad it helped at least a bit!
drowsy geyser
@opal elk Most of my annoyance is in unpacking non-standard data encoding. For example, 4708.223 is 47 degrees, 08.223 minutes. You have to write a method like nmea2dd(encodedData) that does the 47 + (08.233/60.0) to convert to decimal degrees. Not insurmountable, of course, but lots of detail to account for before you can even get a test framework in place.
opal elk
ah, yeah
marble talon
@slender iron Good to know. So a reflash should have gotten me back to CircuitPython, though, correct?
idle owl
@marble talon The flash eraser clears it. Doubletap to FEATHERBOOT after the flash eraser, load the CircuitPython uf2, and then you'd have CP.
In theory π
marble talon
Yeah, but since the neopixel never went blue and there was no pause I don't think the flash worked. If I ever try to take the board back to CircuitPython I might be here again asking similar questions! But I'm unblocked for now for this project and still have another Express board to play with later. Onward and upward!
idle owl
Ah, I see. Ok. Good to know you're moving then! We'll be here for questions π
marble talon
Much appreciated!
slender iron
@marble talon yeah, after arduino you need to reflash circuitpython
marble talon
That's what I tried, but I don't think it worked.
tidal kiln
@marble talon does double tapping to get to FEATHERBOOT work?
slender iron
weird @marble talon
hollow tartan
Hello, everyone. So the buzz is that esp8266 is supposed to show up in windows as a flash drive with some files like code.py, code.txt, main.py, and main.txt . I do not see it on my Windows 7 pro. I have seen the files list by using REPL's >>>os.listdir(). Any clairity offered will be happily accepted.
Goin' to the Maker Space in Marietta, GA this weekend. HooRay!
Hoping to get some Laser Cut Beam Chariot Critter parts and maybe my first 3D print ever. Target: RPi Zero cases and esp8266 cases.
marble talon
@tidal kiln It Actually goes directly into FEATHERBOOT when I plug in the USB. When I eject it in Finder it immediately reappears as FEATHERBOOT
floral dagger
@hollow tartan I don't think the ESP8266 can do that. At least, I haven't seen it happen yet on mine
opal elk
@hollow tartan how do you connect to the REPL?
idle owl
Gah I figured out my code!!
hollow tartan
@floral dagger even with mircoPython or CircuitPython loaded?
floral dagger
@hollow tartan not that I have found, no
hollow tartan
using teraTerm.
floral dagger
Hooray! @idle owl
idle owl
Three days I've been trying to adapt .. I think the terminology is adapt functional code, making it more procedural and less object oriented.
slender iron
@hollow tartan @floral dagger is correct. only M0s can do the USB drive. the esp8266 doesn't have built in USB support
idle owl
@floral dagger Thank you π
tulip sleet
@slender iron I read about some git workflows, and found a lot of dogma. "git flow", "github flow", "oneflow", "threeflow", etc. You could Google all that if you want, but it may not be worth it. The main q is how to treat master: whether as the latest stable release, a dev branch that's always deployable, etc. Most not too relevant to our situation, though it was somewhat interesting to read. It's just a matter of style and what's better for continous integration and various release frequencies.
We can just keep our current situation: 2.x has fixes and enhancements to the 2.x line. master is dev for 3.0. stable should be the latest stable release: right now 2.0.0. It should always be able to be fast-forward-merged from 2.x to the release. I'll fix up stable to be that, or maybe you already have (I haven't checked).
slender iron
sounds good @tulip sleet
half sedge
@hollow tartan The "drive" Circuit Python trick does not work legacy board. You need an UF2 boot I guess. So SAMD is not sufficient, but you don't need Express a Trinked M0 and Gemma M0 also expose that drive. The nice part is that you only need an editor on the host. Pushing file on an ESP8266 is/was still difficult.
slender iron
@half sedge thats true for the boot drive. legacy M0 boards like the adalogger do show a CIRCUITPY drive
opal elk
oh, right!
that doesn't happen for the feather
I can't believe I didn't think of that
you have to use ampy or some other way to upload code
sorry π¦
half sedge
So M0 and from Adafruit is the only requirement?
slender iron
@half sedge if you manage to load CircuitPython on a non-Adafruit M0 you'll also get the drive
half sedge
@slender iron Let's say it does not exist yet... the attack of the clone is to be expected sooner or later.
So UF2 mean easy to flash a new version of Circuit Python.
half sedge
How can we know if someone is already working on porting some I2C device to Circuit Python... to avoid double work?
I have this baby https://www.adafruit.com/product/3595 (in fact a similar more costly available since much longer) and discovered they only provide arduino library. And I wanted to use it in Python...
May I attract your attention to this: https://talk.pokitto.com/t/first-micropython-test/382/8
idle owl
@half sedge I would suggest asking here (which you've done), checking the issues list on Github and verifiying that it's not in the current CircuitPython bundle.
@half sedge That chip is on my radar, but I've got a lot lined up before I can get to it.
half sedge
Somebody try to run MicroPython on a M0 chip device that might be using the same chip as Adafruit CircuitPython stuff.
slender iron
@half sedge please file an issue on circuitpython with the driver label
tough flax
Hi folks, I've been out of the loop recently. Can I get an update on HID over USB and HID over BLE? Specifically, I'd like to know if the Trinket m0 or Gemma M0 can use those now if we add a BLE breakout?
half sedge
@slender iron in the Bundle or in the driver?
Bundle or kernel (or whatever the name)
slender iron
@half sedge here to start: https://github.com/adafruit/circuitpython/issues
@tough flax only USB HID is working. we haven't started bluetooth work
tough flax
Ok, thanks Scott
half sedge
About HID over USB. I had a lot of fun with a Gemma M0 pressing SPACE and BACKSPACE in loop. In chat room, this make it look like you are typing a long message... However, when trying to play with HID over USB on my MAC, I get a message from OSX that say it does not recognise the keyboad and ask to press on a specific key. Is there a trick to keep the MAC happy and accept a Circuit Python as a keyboard without too much annoyance (this is not Circuit Python specific, it is more a MAC issue).
tough flax
@slender iron will the NRF52 Feather support CP? I didn't think it had the memory necesssary?
slender iron
@half sedge I always just close out of that dialog
@tough flax yes but it won't have the USB support
tough flax
??I thought CP kinda required the USB storage device stuff?
idle owl
@slender iron When you have time, should we try to get Sphinx setup?
slender iron
@tough flax its not supported at all now. sit tight
tough flax
Gotcha
slender iron
@idle owl @formal plover was working on it yesterday
idle owl
@slender iron Yeah I remember that. You had mentioned walking me through it yesterday, but my friend showed up. So I wasn't sure if you still wanted to do that.
tough flax
Friendly reminder (:-) When a controller w/BLE HID & USB HID that is USB Storage programmable exists, I have about a dozen AT projects that will click into place. I'm probably up for purchasing hardware, pizza, and beer to make it happen π
slender iron
@tough flax I know. We're waiting for a new chip to do it. https://www.nordicsemi.com/eng/Products/nRF52840
tough flax
Can we do it on two chips w/Trinket M0 & BLE breakout?
slender iron
I don't know
tough flax
Ok, thanks. Don't mean to sound impatient, just hate waiting for manufacturers on this kind of stuff π
slender iron
its not a high priority for us. sorry
tulip sleet
@half sedge I asked a Mac user about that, and the person said it the query about the keyboard type only happened the first time they plugged it into a particular port. Does it happen every time? ... Yes, it should identify itself better, though. You can file an issue here, and I'll investigate at some point if there's a fix: https://github.com/adafruit/circuitpython (it's really a CircuitPython issue at base; the library is not the problem)
half sedge
I had it multiple times... but likely with multiple board. Or I had it once, but I had it with other device of that kind. But yes, it might be that once you skip it, it does not come back.
tulip sleet
@tough flax You could probably work up a driver for the https://www.adafruit.com/product/2633. But the adafruit_hid library uses the HID devices supplied by CircuitPython, so if you want the functionality of that library, the low-level stuff would also have to change.
tough flax
Ok, I have a BLE breakout board (I think its the UART version) - if it's going to be a while I'll write up my first CP library by ripping off their stuff. I only need KBD control, no joystick/mouse (although I'd use Mouse later).
tulip sleet
@tough flax I don't think it would be that hard, since the keyboard presses are just AT commands: AT+BLEKEYBOARD or AT+BLEKEYBOARDCODE for lower-level keypress/release.
tough flax
Right. I'll take a look this weekend
tulip sleet
@slender iron I ordered parts for a Rosie East. I may try to boot the RPi from a USB hard drive, or I may try a little Dell box I have that's NUC-sized. I looked into SLC uSD cards, which are supposed to last a lot longer, but they are quite expensive (so-called "industrial" SD cards). I'll let you know when I have something sort of working (or not).
slender iron
sounds good @tulip sleet !
formal plover
@slender iron & @idle owl, I just walked in the door. What's up?
idle owl
@formal plover We were talking about Sphinx.
formal plover
And yes I got sphinx running, but I have to uninstall it and reinstall. All the guides available are outdated. All the prompts and setup is different
@slender iron I think we lost our Nitro services. Can't use the custom Adafruit Emojis

Still gone in DMs
I don't really care that much, just pointing it out.

Lo, @timber lion diagnosed the Arc Reactor problem with a mere description! RGB NeoPixel ring arrived to replace RGBW, and magically everything works!
@idle owl
idle owl
@drowsy geyser Excellent! I verified it as well - I can get the neopixel ring to work with code from scratch, but not with the prebuilt demo code that talks to RGB.
tulip sleet
@slender iron on adafruit/circuitpython stable branch, did this:
git push -f
So now stable is set to the 2.0.0 tag (it was at 1.0.0 before). Whenever we make a new release, we can do something similar.
slender iron
kk
I was thinking we could have a specific tag or branch call "mpy-builder" or something
to specifically be the version we build against
tulip sleet
That would be OK. It wouldn't necessarily change that much. Does the stable branch influence the readthedocs stable/ tree? Is it going to rebuild automatically?
Should we have a 1.0.0/ tree as well in rtd?
tulip sleet
so we could add 1.x and 2.x to the rtd builds, and give out links to those in preference
slender iron
ya
tulip sleet
I can add those; I think I have the right privs. We have to go out in about 20 mins. Will prob do later tonight.
idle owl
@slender iron I can't picture what the start_tone and stop_tone code would look like. In my mind I'm writing it like circuit.play_tone(frequency, input_trigger) with the trigger being a button or touchpad, and the tone plays for the duration of the trigger event. I can't figure out how start_tone and stop_tone play into that format.
@slender iron Can you give me an example of how you're seeing it?
idle owl
It's so obvious. I was thinking I needed to cram every one of these API options into one line. So I've been trying to work within that this entire time.
slender iron
π
idle owl
@slender iron Thank you π
slender iron
its more like what you did originally
vague monolith
What would be the best way to implement a color chooser? I was going to have a list of colors for neopixels and then when a button is pressed select one of the colors from the list. When the button is pressed again select the next color etc... Would you use itertools.cycle() Or is there some other obvious way I'm missing. I also can't wrap my head on a way to do it without a global variable
slender iron
@vague monolith you could adapt tony's wheel code to only change when a button is pressed rather than time
vague monolith
@slender iron Wheel code?
idle owl
@slender iron I do.
@slender iron Isn't it the same as the demo code on Trinket and Gemma? It looks the same to me...
idle owl
@slender iron Got it, I was just making sure I was understanding the question.
# Color wheel function from neopixel strandtest. This takes in a value
# from 0 to 255 and outputs a smoothly changing rainbow hue. Both 0 and
# 255 values go to red so animations can happen without any noticeable
# break in color.
if pos < 85:
return (int(pos*3), int(255 - (pos*3)), 0)
elif pos < 170:
pos -= 85
return (int(255 - (pos*3)), 0, int(pos*3))
else:
pos -= 170
return (0, int(pos*3), int(255 - pos*3))```@vague monolith you could have a number you increase when the button is pressed and use the color from the above function
vague monolith
I was asking more about.
colors = ((0,0,10), (0,10,0), (10,0,0))
iter_colors = itertools.cycle(colors)
while True:
if button.value:
np.fill(next(iter_colors)
A way in which it would keep track of the current selected color form the tuple or list and each button press would select the next predefined color... Just curious if there was a better way.
Or if I was doing something wrong doing it this way.
sick creek
@slender iron so rosie is build with python?
formal plover
@vague monolith You want to cycle through colors basically?
vague monolith
@formal plover yes
slender iron
that makes sense. you could also just track an index
vague monolith
@formal plover A set group of colors
formal plover
That shouldn't be too difficult to scheme up.
vague monolith
I just alway question that I'm donig something the best way after I implement it.
slender iron
I wouldn't use itertools. I'd just track a count and wrap it using mod (%)
vague monolith
I guess a generator would be more effecient.
Ahh but stop iteration would be raised.
sick creek
I was thinking as Rosie have that linux rasbi guide so
formal plover
@sick creek https://github.com/adafruit/rosie-ci
sick creek
I try to think if the python is good for the test as i dont put linux to my raspi3
ok it should work
vague monolith
@sick creek What?
sick creek
I am going to show you guys Rosie-CI how happy she is with the Fluent UI
basically I put rocie-ci to nanocontainer what go to raspi3 and not run in linux but run it in windows
vague monolith
Ahh
drowsy geyser
Ok, @formal plover , I imagine I'll be instructed to read the manual, but I've been looking at ReadTheDocs and can't seem to locate this bit of information. I'm trying to write the rocket flight control software in CircuitPython, but I'm a bit stuck on the status LEDs. I have an eight-NeoPixel stick for my display, but I can't figure out how to address an individual pixel. For example, I set all the colors to blue initially to show the pixels are working. Then, as a subsystem checks out, I change the associated pixel to green. If there's a problem, I want that pixel to be red. If the altimeter fails to initialize, the first three pixels should be green, the fourth red, and the rest blue..... But I can't figure out how to address individual NeoPixels....
formal plover
@drowsy geyser oh yeah, this is definitely some read the manual stuff. Haha just kidding. I believe @idle owl and I were just talking about this a day or two ago. I have a NeoPixel ring, I'm assuming addressing individual NeoPixels is the same as your stick. I won't be able to check it out for a few days however. Kattni might be available though.
solar whale
@drowsy geyser ```
import board
import neopixel
pixels = neopixel.NeoPixel(board.NEOPIXEL, 1)
pixels[0] = (10, 0, 0)``` here 1 for 1 pixel you will hav e more...
pixelsl[n] is for LED n
drowsy geyser
@formal plover No rush. It's payday, so I have until Tuesday before the rest of the flight controller arrives from Adafruit. π
drowsy geyser
AHHH Magical! It works on the stick! I was indexing pixels incorrectly when I guessed what it would look like!
I was thinking it was analogous to the Arduino addressing, so I was trying variants of pixels.fill(2, (255,0,0))
The way it actually works is much cleaner.
solar whale
formal plover
@solar whale returns! Just in the nick of time!
Well there ya go @drowsy geyser glad to hear you're all set.
One of the many reasons I love this community. There's always multiple people who can help.

@slender iron I had some questions about the lifetime of audio objects, especially that use DMA. Not sure what their state and the DMA state is when they are deinit'd. Trying to mark them as deinit'd in a clean way. Do you have time for an audio or video chat?
slender iron
in 20 minutes or so. finishing cereal now
tulip sleet
ok, tnx. ping me. That reminds me; I should eat lunch.
slender iron
kk, eat some lunch and then we can chat
slender iron
@tulip sleet I'm ready. Lets chat whenever you are back from lunch.
marble talon
@tulip sleet Is it possible (or will it be) to play audio while doing something else in the main loop? I'm trying to do NeoPixels and audio at the same time and when my audio plays my neopixels turn off.
slender iron
@marble talon I think so. The audio should be playable in the background
tulip sleet
@marble talon They shouldn't turn off even if the audio is blocking. But the audio is not blocking. Could you post your code (could be an attachment if it's long; click the plus sign on the left)?
marble talon
tulip sleet
@marble talon do you mean all three pixels go dark when the audio is playing?
marble talon
Yes
tulip sleet
The loop will block while any audio file is playing due to to the while x.playing: pass
marble talon
Actually, I have a 4th that's not part of the code that stays on
Yeah, I grabbed that code from somewhere but wasn't certain of the purpose
tulip sleet
it loops until that audio file finishes. but that should not affect the neopixels. What board is this?
what version of CircuitPython are you using?
marble talon
Feather M0 Express
2.0.0
Yeah, removing that helps, though I do get some artifacts in my audio
And I can't explain all those 256s! Changed to 255s... π
tulip sleet
wait, do you mean they still go dark with 255? 256 is like 0
marble talon
No, no, they just weren't changing brightness. All good and wasn't really a factor. Hmmm. I don't think so, at least? Because the problem went away when I fixed the pass, but the 256 being like 0 would explain the darkness.
I think I need to play with it for a little bit now.
tulip sleet
it's only 8 bits, and that top bit will be dropped.
ok, well get back to us. The 256 didn't register the first time I looked at it. I think that's it.
marble talon
Yeah, I think I converted the wavs to 8 bit with sox. That was a week or two ago so I could be forgetting...
Either way, the pass definitely helps remove the artifacting so I may either have a delay or artifacts. I can probably put up with either in a pinch.
tulip sleet
the width of the wav's doesn't matter. It's that the color values range from 0 to 255. 256 is out of range and will wrap around.
marble talon
Yes, understood. I fixed that. It was just an oversight the first time, but it's possible it was messing with my observations.
tulip sleet
keep testing and let us know the outcome
marble talon
Will do. I'll hit up #show-and-tell. Thanks for the help!
Really enjoying CircuitPython.
tulip sleet
@slender iron ok now?
slender iron
yup!
marble talon
@slender iron Will you be at GeekGirlCon?

Yeah, @fierce oar was pitching it to me.
Looks like I've got this circuit working well enough to make a showing!
CircuitPython ended up working better than Arduino after all. I couldn't get SPIFlash to work from Arduino, which would mean no sound.
There's minor artifacts and I could do with a little more timing flexibility (but would need NeopixelDMA for that, I think) but that's my perfectionist side showing.
slender iron
I'm not surprised there are artifacts. All the audio stuff is very new
going for a run now! be back in an hour or so

Is there a way to create multidimensional arrays in Python? I see how to do it with lists, but not arrays. I could make three arrays, but that just feels wrong π
if it helps, I am trying to modify the motor.py file from the PCA9685 library to work better with the PCA9685 breakout. The one there seems to be designed for the featherwing motor controller version, and has fixed pins stored in a tuple to match the connections to the motor controller. The breakout doesn't need these, so I'm working on a way to edit them.
idle owl
@marble talon That's great to hear!
slender iron
@floral dagger no compact way that I know of
marble talon
@slender iron I was running into a limitation today where there isn't a time_ms, so I couldn't do subsecond delays. Would that be a feature request?
tulip sleet
@marble talon time.sleep() takes a float, so you can do fractions of a second. time.sleep(0.010) would sleep for 10 msecs.
marble talon
@tulip sleet Ah, is the leading 0 necessary? Maybe that's what I missed.
idle owl
@marble talon It's never played nice for me without the leading 0, so that's my assumption
tulip sleet
@marble talon .01, 0.01, and 0.010 are all the same number. I just did this in the REPL:
>>> .01
0.01
Interesting.
idle owl
Now I'm wondering what other thing was broken in my code that I blamed on the leading zero, lol. This isn't recent, but still.
tulip sleet
I can't find any syntax that seems to get confused. The json module wants a leading zero: https://bugs.python.org/issue19871
but otherwise it seems fine. I like adding leading zeros to make it easier to read.
idle owl
@tulip sleet I'm sure it was entirely me. I think I've only ever seen it written with a leading zero so I've assumed it was necessary and have continued to use one.

But.. Sphinx is unhappy with my unsigned short. At least I now know before I break the entire doc again.
floral dagger
is "sleep" the only method working in time? I was looking through the readthedocs page (http://circuitpython.readthedocs.io/en/stable/docs/esp8266/quickref.html)
and this sample code does not seem to be working:
time.sleep(1) # sleep for 1 second
time.sleep_ms(500) # sleep for 500 milliseconds
time.sleep_us(10) # sleep for 10 microseconds
start = time.ticks_ms() # get millisecond counter
delta = time.ticks_diff(time.ticks_ms(), start) # compute time difference```@formal plover Yuuuuuuuuup.... π
solar whale
@floral dagger what is not working?
floral dagger
@solar whale time.sleep(1) is the only thing that is working
solar whale
Hmm. Iβll take a look when I get back to my desk. Should be in the next hour. Do you get errors or just no delays?
floral dagger
i'll try one real quick and post the message...one sec
solar whale
On esp8266?
floral dagger
yes
>>> time.sleep_ms(500)
Traceback (most recent call last):
File "<stdin>", line 1, in <module>
AttributeError: 'module' object has no attribute 'sleep_ms'

``` that's what I get @solar whaleOk. Iβll check. On thought. Try import utime as time.
floral dagger
I tried that earlier. utime is not there
the message is ImportError: no module named 'utime'
floral dagger
ok, thanks. no hurry. In the meantime monotonic is working to get the time, and sleep(0.3) is working as well, so the functionality is there, just not the way I thought π
latest stable, so 2.0 I believe
Adafruit CircuitPython 2.0.0 on 2017-09-12; ESP module with ESP8266
slender iron
@floral dagger ticks_ms is a non-standard thing that micropython introduced to the time module so its been removed.
slender iron
yup, its also non-standard
time.monotonic is the alternative that matches CPython
we've debated adding a precise_time module but anything in the python VM is subject to timing variance
solar whale
@floral dagger - just looks like the esp8266 docs are a bit obsolete regarding time.
floral dagger
ah, ok. Thank you both.
solar whale
@slender iron Is there a description of the CP branches on github - or can you just give a quick explanatiion of them. Is stable == 2.x and master == 3.0.0-alpha?
solar whale
OK - thanks

floral dagger
woohoooo!!!!! encoder wheel is now being read! Now I can start working on motor calibration.
this is the code I am using for reading the sensing pin into an 8 bit number for debouncing. Not sure this is the best way. Is there a more appropriate way to keep the number at or below 8 bit when performing the bit shift?
cState = int(cState << 1 | encoderPin.value()) & (0xff)
royal ridge
Checking brain: time.monotonic is the (rough) equiv of arduino millis(), right?
floral dagger
best I can tell, it is fractional....so kinda @royal ridge functionally it works the same, but the precision seems to go further than millis
or maybe that's just been a quirk with the test readings I have been getting. the digits of precision haven't all stayed the same for me
solar whale
@floral dagger @royal ridge with time.monotonic() I think you alwasy want to call it to set teh start value, then call again and subtract to get the "elapsed time" in seconds (float). the actual value returned is not meaningful - onlty its diff from an earlier value.
x=time.monotonic()
do some stuff
x = time.monotonic() - x
now x is the elapsed time

How do I assign myself to the issue I just opened?
manic glacierBOT
idle owl
@sand bloom I don't think you get assigned to it, you create it and the issue exists with your name on it. There's a driver label though that would be helpful to add.
sand bloom
@idle owl for some reason it won't let add labels
idle owl
@sand bloom I've not had to do it, but I didn't think you needed to have permissions to tag your own issues. I would wait until dhalbert or tannewt are around and ask. On weekends, they might lurk but for the most part they're around on weekdays.

umbral dagger
@slender iron I'd appreciate some feedback: https://bitbucket.org/dastels/dotstar_featherwing
@slender iron I'm working on a "learning guide" type document as well.
umbral dagger
Started working on the first non-prototype (I hesitate to say "production") of my trinket/CP project.
solar whale
@fading solstice Thanks for the dht library - works well. It's very nice to have available. I did find a few errors in the example: ```
import adafruit_dhtlib
should be
import adafruit_dht
then when used the full name has to be used:
dhtDevice = adafruit_dht.DHT22(<pin>)
or
import adafruit_dht as dht
@solar whale I'm just curious: why are you using the DHT rather than something like an Si7021? I started my prototyping with a DHT, but switched for the I2C bus and the smaller (post-breakout stage) part.
solar whale
@umbral dagger I just saw that the dht library had been added and have a few laying around so I thought I'd give it a try. Si7021 is next on my todo list π I agree that the i2c sensors are very nice.
fading solstice
@slender iron what branch should i make my changes to for the "ustruct to struct" issue . Iplan on making my own branch, but I wondered what it should be created from inially
@solar whale yes please add an issue.
fading solstice
@umbral dagger @solar whale i think that it happened only because i wanted to write one AND the adafruit store still sells DHT sensors. Gave me a chance to get my feet wet on a low risk project.
floral dagger
I'm really starting to like circuit python. It's taking me some time to get the basics down (python noob), but so far it all seems very straightforward. Nice work folks
idle owl
@floral dagger That's great!
floral dagger
managed to port my little rover/bot project over to CP pretty easily. I'd expected it to take the rest of the weekend to get the coding done, but functionally it's about ready. It's surprising how well CP works.
idle owl
That's great to hear! That's the goal.
@floral dagger I'm a Python noob too, started with it three months ago, and ended up doing a lot of my learning through CircuitPython. I found it easier to get into when I had immediate results on a board. Blinky lights are great!
floral dagger
nice @idle owl. Yeah they are. It's pretty cool to have physical feedback.
Now I just need to figure out this github monstrosity, and start poking around in the code.
idle owl
I'm just learning that too. I have basic commits figured out, and working with branches. Most of my usage involves going back through my terminal history because I haven't gotten much of it memorised yet.
floral dagger
Yeah, it's a lot to pick up for sure. I'm still hoping to find that one person that can explain it without using terms that only someone who knows how to use github would know. I'm sure they're out there somewhere.
idle owl
I totally get you there. I've got a friend who can. That's who has been teaching me. I've watched presentations on it, and most people, like you said, use git terms and that doesn't help if you don't know them.
floral dagger
lol ikr....all I hear is "ok, now you jus flippityfloo the whatsit, and that creates your bloppiter for your flamwangler"
idle owl
lol exactly!
idle owl
@floral dagger By the way, if you have any git questions, feel free to ask. If I haven't learned it yet, I have someone who can explain it to me in normal terms, and I might be able to bring it back to you the same way. There's a few people here who were able to explain some things to me as well, but I can't recall if I'd already started using it - which is to say using git terms at that point wouldn't have been gibberish to me if I'd already been working with it some.
umbral dagger
@floral dagger Same here (wrt CP). I was exposed to python in 2003 but never cared for it. I tried it again 5 years later at Google, but it didn't click. Ruby always filled that niche for me. CP feels fundamentally different, however, and I'm rather enjoying it. Still running into plenty of "how do I do that in Python" moments, but getting some real code written.
@floral dagger @idle owl I'm using GitKraken for most of my git use these days. Cross platform, free for non-commerical use, and is pretty decent. So mostly that, and then some command line use as well. Git is pretty much the standard for source control now.
idle owl
@umbral dagger The more I use it, the more it's starting to gel for me, but I'm still getting started, so there's a lot of asking the same questions.
umbral dagger
@floral dagger @idle owl Git is massive in terms of what it can do. I've been using it for over 10 years and use/know a portion of it.
idle owl
@umbral dagger Yeah my friend who seems to know it inside and out has been teaching another friend pretty much weekly for 3 years and he's still in the dark about so much.
delicate pike
Thanks to Hak5 they explain a lot of such things
solar whale
@umbral dagger got the si7021 and an mcp9808 up and running - all 3 sensors are close in temperature but the si7201 does do a better job with humidity. Also get occasional errors reading from the dht22 - that is typical in my experience. I would definately recommend the si7021 or mcp9808 if you dont need humidity.
umbral dagger
@solar whale I used went with the Si7021 for my sensor node design. I'm sticking with it for version 2. I've added BMP280 (for barometric pressure... not sure it it's worth keeping in the long run), and am interested in seeing how the temperature readings of the two compare.

@timber lion I tested your mega demo (the Monday dropbox zip version) and found two bugs.
@timber lion If you get into the touch demo, activate the sound option, trigger a sound and switch to the next demo. The sound stay and never stop.
idle owl
@half sedge He mentioned that when he talked about it before posting it. He hadn't put in a hook to stop the tone.
half sedge
@timber lion Then, if you switch to another demo a few time, it get stuck after the rainbow.
@idle owl Yes, but latter, it freeze completely when looping through the demo.
Anyway, that demo is a very good selling point. I showed that at an hacker space... and they did put that on their shopping list. π
It would be great if the demo would work with the mega.py version. Because that is editable on the fly.
I believe that removing the accelerometer demo and code would make it much smaller.
idle owl
Not enough memory. We're working on integrating a few things that might make that work, but we won't know for a bit.
Removing it does help, but it can still run into memory issues.

hi smart people. My metro express board is sad. 2 clicks on the reset button shows the Boot Drive and I can copy a different .uf2 file onto it, but the run-time drive shows and disappears quickly. plus the serial communications is not allowed. This happened right after copying updates onto the drive. The drive will not mount on either ubuntu or windows. Is there a way to set the board back to factory settings?
idle owl
@fading solstice Have you tried the flash eraser yet?
fading solstice
no, i did not know about the flash eraser
idle owl
Excellent! Download the right file from here https://github.com/adafruit/Adafruit_SPIFlash/tree/master/examples/flash_erase_express and follow the instructions from here: https://circuitpython.readthedocs.io/en/latest/docs/troubleshooting.html#file-system-issues
Basically download the uf2 file and drag it over, and it wipes the flash completely.
Then you need to doubletap reset it again and copy your CircuitPython or desired uf2 file to it.

One other question: If I were to get a Saleae, which would be good for this type of dev work? I was looking at the Logic 8 bit would the 8 Pro be worthwhile for any reason?
timber lion
i think the regular 8 is good, the pro is just faster and has analog
but for I2C and basic SPI sniffing up to 50mhz or so from the basic is fine
i2c is 400khz and sometimes 1mhz, SPI varies but really only big LCD displays run fast (multiple megahertz)
pastel panther
The docs show the 8 having analog inputs. Is there something that the 8 pro has that makes analog support better?
timber lion
oh interesting yeah looks like they do have analog on the non pro too
it's just a little faster so can get more signals, but it's not really a proper oscilloscope.. like it doesn't have the same protections or voltage range
good in a pinch but not a replacement
the 4 would be too limiting i think though, you really want 5 pins sometimes for SPI devices to see the CS line, enable line, etc and clock, miso, mosi
pastel panther
Trying to decide between an Rigol 1054Z and logic as a first purchase. I'll probably get both eventually but I'm leaning towards the Logic first
