It doesn't seem to be rest related - just hangs after a few minutes - even if I'm using it

[haughty quiver]

OK, all my tests have been on mac os, iOS, and on MIDI Host synth devices.

[pearl shoal]

No Events in EventViewer

[haughty quiver]

I'll test on Windows 10.

[pearl shoal]

Thanks, John

I love using the MIDI on OBS-Studio - it's no nice to not worry about keyboard focus

[haughty quiver]

Well, this bug hunt will not be as simple as hoped. Works fine for me on Windows 10.

[pearl shoal]

I've switched to Katttni's code - I'll keep checking

OH! Timing is everything - just failed again

[haughty quiver]

@pearl shoal do you have any commercial MIDI devices that you can test?

[pearl shoal]

Yes, I have one of these I can test tomorrow https://www.sweetwater.com/store/detail/XTouchC--behringer-by-touch-compact?mrkgadid=3301331902&mrkgcl=28&mrkgen=gpla&mrkgbflag=0&mrkgcat=studio&recording=&acctid=21700000001645388&dskeywordid=92700046938536218&lid=92700046938536218&ds_s_kwgid=58700005285190833&ds_s_inventory_feed_id=97700000007215323&dsproductgroupid=470064303503&product_id=XTouchC&prodctry=US&prodlang=en&channel=online&storeid=&device=c&network=g&matchtype=&adpos=largenumber&locationid=9012383&creative=280136033998&targetid=aud-377243944533%3Apla-470064303503&campaignid=1465808290&awsearchcpc=1&gclid=CjwKCAjwmK6IBhBqEiwAocMc8ixkG_EDgTK64M6agQ_XoaTESKiLwl4bNJB00wzZ8A3Mo_F42zmL3xoCw1UQAvD_BwE&gclsrc=aw.ds

[haughty quiver]

Are you running OBS during these tests, or any other programs that are doing MIDI things?

[pearl shoal]

Nope - just the MidiView

Even closed the browsers

[haughty quiver]

Hmm, at this point I'd be trying different USB cables, hub/no hub type of stuff.

@pearl shoal do you have a Windows power management setting for allowing the computer to turn off USB devices to save power?

[pearl shoal]

Nope - and it's plugged in (and I'm using it) when it fails

I just switched it to another USB port (might as well check)

But it's weird that the MSD and Serial connections are still good

[haughty quiver]

Yes, weird. A lot of the searches on "USB MIDI device keeps disconnecting on Windows" turn up things about the USB selective suspend setting.

https://www.windowscentral.com/how-prevent-windows-10-turning-usb-devices

I have no idea if that is able to do it's thing while you're actively using it, but maybe for some weird reason it does?

[pearl shoal]

Just stopped in the middle of me moving the knob (in the new USB port)

[haughty quiver]

Are you able to unplug most USB devices (webcams, audio interface, etc.) and test it?

[pearl shoal]

I have no other USB ports

Just a Bluetooth mouse

I mean no other devices

[haughty quiver]

right on

[pearl shoal]

Internally there may be the trackpad

[haughty quiver]

Let us know how the Behringer controller works out so we can at least rule out wholesale rejection of MIDI by your computer :)

[pearl shoal]

Yes - let me go get it from my truck

hold on

Testing the behringer

Seems solid (will keep testing)

I actually really like this controller

[haughty quiver]

OK not sure what would be causing the issue, so hopefully @paper peak may have some ideas of what's going on on your system that is making the Macropad MIDI stop. Have you tried MIDI with other CircuitPython devices? Like just have a feather repeating a note on/note off endlessly?

@pearl shoal out of curiosity, does this happen if you press keys on the Macropad to send midi note on/off? On the off chance there's something funny about your encoder that is causing it to spam messages at some crazy rate

[pearl shoal]

It's not the encoder - buttons do it too ... it stops sending any Midi commands

[haughty quiver]

OK

[pearl shoal]

And the Behringer doesn't seem to be failing

I have a Circuit Playground I could setup to send notes

[haughty quiver]

Got it, that could be a good thing to test. I think this is now in Dan territory :)

[pearl shoal]

Will you do me a favor and leave yours plugged in overnight?

see if it's still working in the morning?

[haughty quiver]

I've done that before, but I'll try to do it again.

[pearl shoal]

ok

[haughty quiver]

If you have a different Windows machine to test on that would be helpful in figuring out if there's some particular driver/application/whatsit that is part of the chain of weirdness

[pearl shoal]

nothing handy - but I will tomorrow

Thanks for looking at it

I don't think this is in the python code - I think it's lower

[haughty quiver]

Ah, looks like it could be related to https://github.com/adafruit/circuitpython/issues/4190

@pearl shoal one last thing -- try absolute latest CircuitPython 7 build from Amazon S3 -- there may have been MIDI fixes since the release you used in your GitHub issue.

[pearl shoal]

Tried the latest (and one @paper peak sent with more fixes. Same results

It matches that other issue though. And I am on a Dell laptop

@hollow dust commented so he’s on it. I’ll be happy to help debug or provide remote access

I saw a food truck yesterday called “Jurassic Street Tacos”

And it had a T-Rex wearing a poncho and a sombrero eating tacos

[haughty quiver]

thanks so much for sharing this, it works great -- I used it to re-generate my plate layout as a .dxf, brought it into Rhino/Grasshopper, and build the model. I'll include these resources in a guide.

[eager matrix]

I once used a Circuit Playground Express and touch sense to set up macros for VLC when I was transcribing some audio to go back or forward 5 seconds. I connected the touch sense pins to tuna cans and put them on the floor and they worked as individual foot switches. (Yes, I had to do this barefoot).

[waxen thistle]

From youtube:

that's fine, i'm always barefoot

I don't usually smell of tuna though

Question from Youtube:
​is there anyone in here who'd be able to tell me: On the Trinkey QT2040, which pin do I use as a 'switch' in order to allow CircuitPython write access to the board's flash memory?

[smoky island]

PaintYourDragons game has inspired me to explore more possible games for the MacroPad. The first one that I think I'm going to make is a game kind of like Simon where it lights up the keys in sequence and then you have to try to remember and press the keys in that sequence. I'm excited to see what other games folks can come up with that hardware.

[paper peak]

you can use board.BUTTON

which is the bootsel button

[modern night]

That's a clever solution

I have a dumb thermostat where in order to raise the temperature you have to hold the button down for a certain length of time. It's almost as if it's polling really slowly.

[waxen thistle]

Question from Youtube:

​My interest is with Raspberry Pi projects. I learned Python while building my own "Learn Robotics with Raspberry Pi". How would a RP2040 project be a good way to get started with CircuitPython?

My response:

​It'd be a great starting point, though it'll need some soldering skills. For a solder-free experience, you can look at the Adafruit CircuitPython Bluefruit or Adafruit Clue boards.

[paper peak]

i would also suggest looking at the Crickit boards. You can use a Feather RP2040 (and many other Feathers) to do motor and servo control.

It doesn't have to be RP2040 per se. Any CircuitPython board could work for you. We have many robotics projects in https://learn.adafruit.com

[waxen thistle]

Question from Youtube:

​couldn't you also (soften / smooth) the animation by having the leading edge turn on at say, .25 brightness?

[woven mirage]

Like antialiasing

[eager matrix]

@paper peak Please don't forget about SWD pins on the Macropad.

[waxen thistle]

The RP2040 has one serious benefit -- it's very inexpensive 🙂 And during this chip shortage, it's one of the few microcontrollers available.

[rotund marsh]

Thank you Adafruit Team for creating HW & SW for MacroPad, perfect for use when remodeling my Jefferies Tube #2. Also looking to integrate MacroPad with Raspberry Pi being used for Jefferies Tube cam/audio/speech.

Question from Youtube:

​I'm wondering if it is possible to add a airlift co-processor to a MacroPad

ASCII art. Very readable

[strong acorn]

curious if there's an advantage of using microcontroller pins and not board?

[grand tusk]

Looks like code used for touchscreen.

[woven mirage]

No type hints?

[smoky island]

it is possible to add them in PyCharm now.

[robust horizon]

@strong acorn not really. in this case, the cheat-sheet I referred to had the microcontroller.pin names not the board names, so I just went with it. for an adafruit board I wouldn't have done it, but the feather s2 was just documented a little differently

Questions from YouTube:

​general question (macropad is my first project in this world) is there an automated way for including libraries? or do you have to hunt them out?

​can you explain "It works in the background" a little more fully?

​Any cool use cases you could quickly share? Anyone known to have used this for access control?

Question from Youtube:

Peter Lindstrom
​And it is written in python or is it C or assembly?

[rotund marsh]

[wind spoke]

Any examples that show NumLock status display on the MacroPad yet?

[paper peak]

[waxen thistle]

Question from YT:

ZiMarts
​is these circuits like Circuitphython, arduino etc. pretty much similar?

[rigid fractal]

The latest video on new Adafruit products covered a tiny solenoid

[modern night]

How often do you go through the old projects you've made that are running 'around the house' and update the versions of the code?

I have put magnetic feet on my MacroPad but I miss a LiPo input like on many other board. Any other powering option? https://twitter.com/DavidGlaude/status/1423309130044002305?s=19

David Glaude🦠💉💉 (@DavidGlaude)

The #MacroPad from @adafruit is great... but it is missing one feature that was in the #MagTag: The LIPO connector to power it.

With magnetic feets, you can make it a kitchen MacroPad that fit on the fridge microwave, air refresh.

Could use that as timer or cookbook.

M0 ❤️

[upper sandal]

The SAMD21 can be frustrating in Circuitpython when you want to grow your project and import more libraries, but I still use M0 trinkets for some small projects

[desert orbit]

I've run into that with a few things with some heavier drivers but i found that the memory limitation helps me focus and avoid feature creep 🙂

[pearl shoal]

Love to see all of these

The M0s (especially the trinkets) are very handy as USB Host chips (using Arduino)... I pair them with an RP2040 or M4 running CircuitPython connected via UART to make HID converters (gamepad->keyboard, weird keyboard to standard etc.)

[modern night]

The magtag is one of my favorites. If there wasn't a shortage I'd buy so many. ...Probably a good thing for my wallet that I'm not 😅

[desert orbit]

funhouse is a fun board, i like using the mini magnet feet on it 😄 https://www.adafruit.com/product/4631

[upper sandal]

I use a 3D printed base to hold my magtag, but I added magnets so I don't have to screw/unscrew it. My FunHouse uses branded plastic construction toy bricks in all caps.

[tulip canyon]

QTPY ❤️

[desert orbit]

love those for breadboarding 😄

[tulip canyon]

Standards by popularity works so far

[tardy tendon]

The great thing abut standards is that there are so many of them.

[waxen thistle]

There are so many boards that require zero soldering -- between onboard sensors + StemmaQT.

It's so easy to get newcomers quickly programming and doing things with microcontrollers. Lowers the barrier to entry.

[upbeat coral]

Beware LIPOs for RC crafts, they are wired backwards and will fry a board. "Things were tried, mistakes were made".

[desert orbit]

the existence of two different wiring 'standards' for two JST Lipo pins has created so many tears 😦

[sly radish]

Leave the bulk of uniqueness to those with edge-case requirements - Python is the ubiquitous tool

[pearl shoal]

Even us old dudes started with interpreted languages (BASIC, Pascal, etc.). We moved to C/C++ when we needed speed, flexibility & control.

[viscid bolt]

Don't forget assembler

[waxen thistle]

Even after experience with lower-level development, the first thing I grab when working on a new project? A solderless board that runs CircuitPython. Life is busy, make it easier please.

[desert orbit]

never noticed that circuitpython compatible game boy cartridge, looks neat 😄

[pearl shoal]

QT Py RP2040 has the Binko jumper on it 🙂

[tardy tendon]

Us old duds entered our first programs using toggle switches on the front of the CPU.

[inner spade]

I appreciate the fact that CircuitPython can be put on my custom, non-commercial boards. Support for new CPy releases is automatic. Thanks!

[waxen bough]

I ❤️ my NeoTrinkey password typer!

[rapid hornet]

I need to redo it with the rp2040. the samd51 couldn't quite cut it. I did see someone do a thicker board that doesn't need a plastic case

I was just thinking I need to pick it back up

[desert orbit]

PIOs might help out with some things maybe? haven't tinkered with the gameboy, was team atari lynx as a kid. 😂 wish i still had that thing..

[rapid hornet]

yup, exactly. I'd love to make a lynx cartridge too

[eager matrix]

Is adafuit.io open source as well. In particular can people self host the server.

[rapid hornet]

and game gear 🙂

[waxen thistle]

Game gear! that's a name I haven't heard in a long time....a long time.

[eager matrix]

You folks should make a calendar called "the awesome nails of Adafruit"

@proper trench Wokwi also simulated serial, 7 seg LEDs and variety of other things including a logic analyzer and is graphical and allows you to single step for debugging. There's link for their discord on their docs page. DM me if you'd like a direct contact for one of the developers.

[upper sandal]

[eager matrix]

@upper sandal Have you been using it. They are pretty close to releasing for ESP32 as well.

[woven mirage]

Thanks, @upper sandal. How does that differ from Tinkercad Circuits?

[upper sandal]

I just posted the link to help, I don't know about it 😉

[eager matrix]

Cool. It worth checking out. They did a super nice job with it. It's really new so I'm sure it's going to get ore complete but it's great for a bunch of things.

Hi, folks 👋

Happy CircuitPython Day !!!

[upper sandal]

speaking of, I bought a hiibot IOTS2, it comes with CP 6.2.0 and a working tinyUF2 (and a lot of demo code), but none of those are in the repo, somebody tried to PR it to CP months ago but had no vid/pid and did not come back

I might try my hand at doing the port with vid/pid from Espressif

[clever summit]

Hello from the Weblate Gang!

[warm dust]

@rapid hornet Can you go over the MP_STATE_VM stuff and when to use it instead of global variable declaration...
the context being your review comment on the atexit PR

[rapid hornet]

https://www.reddit.com/r/Python/comments/oyrqp0/welcome_to_a_joint_ama_with_some_of_the/

[modern night]

Can I ask a followup to a question from the AMA: One user asked about threading, and the response was that it was difficult to do true threading for a number of reasons. Assuming that at some point more pythonic style threading gets implemented, would either circuit python or micro python run into GIL like issues?

[sudden slate]

I'm back - new headphones!

Super weird sounding too - my backup pair 😉

[warm dust]

np 🙂 lets save the deep dive for later 🤿

[left pier]

I'm so behind... I've not listened to the Talk Python to Me episode yet and now there's an AMA I've not seen too.... so much to do ..

[sudden slate]

I think so

[modern night]

Neat. I didn't even know enough to know if it was an obvious question to answer

https://www.reddit.com/r/circuitpython/

[sudden slate]

oof

[modern night]

ahh the joys of reddit...

[sudden slate]

Is Fish Shell worth using?

[waxen thistle]

Memory? I remember this being Scott's first stream 🙂

[sudden slate]

I ran out on the MacroPad from too many macro files

I had to delete the Adobe ones cause I don't use Photoshop or Illustrator

https://tenor.com/view/minion-memory-alert-gif-9313925

Scott likes Fish.
I use OhMyZsh.
They're both better than not using one of them.

OK. I'll look in to that

[grand tusk]

Deep Dive: Flashback

[sudden slate]

[cinder wind]

Yes I think so! I was trying it out on Open Hardware Summit 2020 badge (also NRF52840 with SPI display) and it worked pretty well

[sudden slate]

I wish C++ had garbage collection like JS - I don't like JS very well, but I like C++....

Does Python have garbage collection? I haven't ever needed it, so I don't know

OK.

(how to control the garbage collector)

[waxen thistle]

Ah pointers. The joys of wrestling with "zombie children."

[sudden slate]

Build on what you know as you need it.

I use Opera GX and Firefox as browsers - Opera GX for the Discord built in and speed, not gaming

[timid plover]

what if there are more than "[10]" register in collect call to get registers?

I hate magic numbers 🙂

[sudden slate]

I'll be pushing a commit in a few so you might as well get a chance to do a live review 😉

[modern night]

That is really relieving to get past those, "There's no reason for this" errors

[cinder wind]

omg the linker was busted too? wowow good job figuring all this

[simple fractal]

nothing like when your tools are borked.

[eager matrix]

Have you used Wokwi? It's a web based simulator with a really nice gui showing circuits. It supports arduino, Pi Pico and they are going to release ESP32 soon. It's got support for keyboard matices, LEDs including 7 segment, and you can connect a virtual logic analyzer. It does single step debugging as well and handles PIO with debugging on the Pi Pico. It also does micropython and they just started working on CP. It's at https://wokwi.com/

[simple fractal]

or building on a house of cards means it may all collapse.

[eager matrix]

I can put you in contact with one of the dev if you are interested. DM me if you liike.

[smoky island]

Wokwi seems super cool, just learned about it yesterday. Glad to hear CircuitPython is in the works

there are a bunch of hardware devices in the emulator also

[sudden slate]

Grocery run 😦 See ya

[modern night]

I use to be super in favor of simulators, but that was because at the time it was so expensive to even buy a dev board. Now it's a lot easier to justify just grabbing one for me

[left pier]

[eager matrix]

Cool. I'll let him know.

[smoky island]

what was the power system for rosie? that sounds like it'd be a mess in that alone, let alone managing all the usb devices

Dawww

[grand tusk]

[sly radish]

would the scale auto-adjust to zero after exit?

[smoky island]

I don't know if they are still easy to get but the Wii boards make good scales for hacking. They plug into the wii remotes which can communicate to things with bluetooth.

[upper sandal]

mah shredder !

also the wii balance board is I2C then ?

[modern night]

So how long does the interrupt take to fire and load into state/what's the resolution of it?

ohhh ok, that's comfortably slow then

Ok cool thank you!

[rigid fractal]

Okay thanks, I will give it a try on the CLUE 👍

[sly radish]

@rapid hornet Thanks for the Deep Dive ... Have a Great Weekend!

[timid plover]

[brazen quail]

Can you use DMA between Neopixels and i2c on any CP targets ?

[compact sandal]

Cypress (now Infineon) PSoC chips have a lot of peripherals that are connected to the DMA and the digital programmable logic array is also connected to the DMA controller and the GPIO is connected to the programmable logic...

[clever summit]

Hey Foamy. So you are on it today as well.

[viscid bolt]

I'm here

This one is the actual gauge and not the arc

First time writing a class

Start of gauge

random point

That part is VERY slow

[viscid bolt]

note the line at 70% on gauge 1. that marks the end point of the fill.

BoundaryFill

it looks like self.boundaryFill call has color hard coded

That is used to determine end of fill. so progress line

https://www.geeksforgeeks.org/boundary-fill-algorithm/

[grand tusk]

Could you use a TileGrid to double-buffer the bitmap?

Paint one half while the other half is displayed.

Update the one tile when it's ready.

Flip from the left half of the bitmap to the right, back and forth.

[viscid bolt]

boundaryFill needs to be replaced. On large gauges it's slow and on larger screens is runs out of memory.

[smoky island]

https://gist.github.com/FoamyGuy/8fe27cdec0dc0febad754c186090a5da

[ebon stratus]

I'm sorry Ladyada didn't see my suggestion for new neo pixel glasses before she spent all that time on traces. 😦

[inner spade]

YT is quasi-live -ish.

[waxen thistle]

Same with twitch. We get about 3-4 measures, then round n' round we go.

[waxen thistle]

SAMD51....I remember when they were available. The good old days

[fluid drum]

nice discount for this item!

[lilac tusk]

Same

Now they are but a distant memory

[cinder wind]

but you can order up to 10 Pybadges and get the SAMD51s off them ahaha

[shell mason]

pybadge the nice pick of the week

[grand tusk]

Where'd you get the giant Arduino?

[waxen thistle]

We joke around, but I wouldn't be surprised if we'll be seeing that mindset in the not-so-distant-future.

[viral sail]

Instead of "extra mile" it should be "extra parsec."

[cinder wind]

I've already heard someone doing this for STM32 and their stash of STM32 dev boards

[shell mason]

think pi2040 pybadges

[cinder wind]

https://github.com/todbot/circuitpython_staroids/

[waxen thistle]

The longer the shortage continues, I bet we'll see more platforms migrated over to the RP2040 chipset

[cinder wind]

The retro green color and sounds are all JP. looks & sounds great!

[waxen thistle]

And it has a TFT! Another rarity in 2021.

[clear matrix]

I did not read that as staroids the first time through.

[teal river]

I got stuck on a call and couldn't join the stream, but ordered 2 PyBadges! And a battery and speaker for each. And 2 more battery fuel gauges. And a solar LiPo charger. And a baby USB LiPo charger. and another QT Py RP2040. I determined that you can only pay in Bitcoin if it's $100+ for the order...

[clear matrix]

It's been excellent watching that game evolve though.

[teal river]

I gotta run! hope everyone gets one who wants one!

[waxen thistle]

You and me both!

[cinder wind]

hahahah

[grand tusk]

We wanted a 'what's for dinner tonight' board. Problem solved!

[inner spade]

I've used the PyBadge as a front panel for a number of projects.

[waxen thistle]

If I didn't already have a few of them, I'd jump on this. It's a stellar price.

[fluid drum]

Ordered a couple. My son and I will do some sort of badge for our booth at an upcoming con

[viral sail]

[cinder wind]

great pew pew noises you added, JP!

[haughty quiver]

pew! thanks for this excellent code!

[haughty quiver]

no doubt

[ebon stratus]

before y'all go away...I have to snip off the little tabs on the edges of a Kailh switch, right?

they're on the shell elge. 3 litle tabs

[haughty quiver]

I insist. Thank you

[haughty quiver]

what are you trying to do with the switches?

[ebon stratus]

on the "shell" there are three tbls...like maybe from manufacturing. they need to be snipped, right? Don't fit into the pcb if they're there.

they are on the square body edge

[teal river]

I've never had to cut anything off -- picture?

[haughty quiver]

there are round pegs on the bottoms of most switches for mechanical stability. The ones from adafruit have one peg, some others have three. Is that what you're talking about?

[ebon stratus]

hang on a minute, please, then. I'm losing my eyesight so I do a lot by tough.

[frosty belfry]

That's the bottom of a kailh from adafruit

[teal river]

Ah, I see, the nubbins in the corners? They hit the PCB?

Also, you have two accounts? XD

[frosty belfry]

No, just had a kailh in arm's reach.

[teal river]

Ohh, I thought you were Tyrone on a different device/account because he said one moment and you spoke next XD

[sonic pike]

I need to schedule my purchases better... my previous order just shipped today before the livestream. 🤔

[teal river]

Just order daily and you'll get things daily

[ebon stratus]

yes @teal river

So ship them nubbling right?

[teal river]

Yeah, worst case those switches lose a tiny bit of mechanical stability in a socket that supports the extra nubbins. But you can print a stability plate if you have a 3D printer

[ebon stratus]

they won't snap into place if they're there, unless I'm doing. somehting wrong. I know I sound stoopid, but this is frustrating.

🙂

[teal river]

The only stupid questions are the ones you don't ask! Nothing wrong with asking when you're not sure

[ebon stratus]

Hi all! Do the Compute Modules have the Bluetooth/WiFi on board?

[upbeat coral]

@pearl shoal depends. You can get with and without

I still have two "As seen on Show & Tell" badges left for any community members presenting on Show and Tell, if they want one (@clear matrix @haughty quiver )

Didn’t make it in time for show n tell

Currently solder up this board

Hopefully final revision before production 🌈

And if you choose to photograph and put your vaccination card in a password protected cloud storage, it might be a good time to photograph all your important documents -- ID cards, passport, car insurance, medical cards, other vaccination records, etc.

Create a digital "important documents" folder -- great to have as a backup in case of emergency.

I like the new CircuitPython Parsec theme

[robust horizon]

little known fact: parsec is a measure of frequency, not duration. 1 parsec is equal to approximately 7 cents, or 1/14 of a semitone.

[teal river]

Also 1 parsec = 3.26 lightyears

[waxen thistle]

There are "sample" sets out there, like this one: https://kbdfans.com/products/kbdfans-72-switches-tester-all-in-one?_pos=3&_sid=43d16761a&_ss=r

[upper sandal]

parsec is a unit of measurement of Kessel runs

[waxen thistle]

Han Solos divided by Lando Calrissians. Carry the Chewbacca.

[sudden slate]

19.2 trillion miles = parsec

[teal river]

If only that wasn't as expensive as a keyboard :P

[waxen thistle]

Oh, you shouldn't look at the costs of some mechanical keyboards then. $59 is a drop in the bucket. Some keycaps alone are $100+.

[teal river]

Question: Can we send the Adafruit crew mail?

[waxen thistle]

Can you put LED in resin?

[robust horizon]

@grand tusk I bet you could

[sudden slate]

Where do you get the resin?

[waxen thistle]

I remember seeing Epilogs many, many years ago at various industrial trade shows in NYC.

I wish I had one. And the space for one. And the exhaust system for one. And the floor structural support for one, since I live in a 3rd floor apartment.... you catch my drift.

[river peak]

This makes me think of making dice

[teal river]

@cinder wind it doesn't like me DX

[cinder wind]

what board? and what version of CircuitPython (this requires CP 7)

[teal river]

MacroPad, CP 7.0.0-alpha.5

[grand tusk]

Those keycaps are awesome.

[river peak]

If the surface is still tacky, then you can also cure it some more once it's out of the mold. The mold does absorb some of the UV

[sudden slate]

Poor transistor

[grand tusk]

It is protected.

[smoky island]

if you run this in the REPL what does it show?

import os
print(os.uname().machine)

[smoky island]

it looks like the game code is expecting "MacroPad" with a capital P. I wonder if the value got changed to a lowercase in one of the newest releases.

[cinder wind]

fascinating. did they change the 'p'? let me check my version

[sudden slate]

Interesting...

[smoky island]

on line 16 in the game code you can change the string to "Macropad" with lowercase p and it should work I think.

[teal river]

Looks like it, changing it to "Macropad" worked

[upper sandal]

tsk tsk .lower() is your friend

[cinder wind]

yep. dunno how that got in there. haha sorry!

[teal river]

@cinder wind Quickly accelerating forward when you fire is counter intuitive XD I expected it to kick me backwards when I fire

[brazen quail]

PGIA built in ?

[cinder wind]

ooo neat try to add that!

[sudden slate]

How many NM UV do you need to cure the resin for the keycaps?

[hot frigate]

@cinder wind Hi, mine error'd out trying to find and load the board. I'm using a MacroPad. I just deleted all of the non-macropad board "else" sections of code, and it worked.

[lilac tusk]

Threw the metro ESP32-S2 bootloader on it and it flashed 🙂

[sudden slate]

What if you just commented them out?

[hot frigate]

It would have broken the If statement.

[teal river]

You might also be able to add more sophisticated controls and settings for, say, the MacroPad, since your code already picks out what device it's running for

[cinder wind]

yep. @teal river just found that too. Fixed on github now

[waxen thistle]

You can't stop the beat either 🎵
