Jinx! 😀

[wind spoke]

Can you cut here? :

[haughty quiver]

that seems plausible

[sand lotus]

technically you can cut anywhere you want, but should you..

[wind spoke]

Those are doubler, but is it a visible trace?

[sand lotus]

yeah that would do it, only place you can because those traces are on top of each other whew

[cinder wind]

yeah that seems like a good place. then you'd have those inner pads to jumper to where ever you want (and easier than doing both a top & a bottom trace)

[sand lotus]

why are the traces going straight through the via next to the usb pin?

[dry marten]

Thanks for the show

[cinder wind]

just another place to get at the SDA & SCL lines going to the StemmaQT connector (labeled "C" & "D" on the silkscreen, but "D" is rotated 90º for some reason

[sand lotus]

maybe different way eagle does it, seems like it's not connected to the ring when it's running through it? it's gotta be though yeah.

if you wanted you could bypass pins 4 & 5 just leave them empty, and use those 2 jumper pins instead to bodge wire to whatever pin you want. it's a nice thoughtful addition.

[cinder wind]

totes. if you can spare leaving GPIO4 & 5 unused

[nova totem]

I'm looking at the PixelMap core PR right now too @robust horizon. Great work on all of this

[robust horizon]

scott is about 16 steps ahead on this whole idea

so watch out for him!

[sand lotus]

really nice projects scott. that's some advanced stuff of course.

[rapid hornet]

yup advanced. I hope it can be helpful for folks who just use the libraries a few advanced folks make

[dim wigeon]

Seems like you could almost make a CircuitPython-powered BusPirate that way.

[rapid hornet]

maybe. the chip only has 8k ram though

so not a very big buffer

it does have fast io access from the cpu

[dim wigeon]

Interesting possibilities.

[lethal lagoon]

wow amazing mods for that Lego noodle shop! need that

[sand lotus]

ah a lego noodle shop for the noodles. that's great.

[lethal lagoon]

didnt know there was one!

[robust horizon]

that looked great N+P!

[sand lotus]

sophy's mesh 3d printing ideas continually elevating. brilliant idea.

[hot frigate]

This whole concept is a brilliant idea. Ultimately, isn't the challenge the communication bus protocol? I love the whole thing, overall. I've built a number of end-of-line testers and I have had thoughts about making something similar, but it's a big project. I stopped at what I was going to do for the bus.

[smoky island]

Such a neat way to integrate touch pads. Really cool the way it works in 3D with the mesh and flexing it to make the panels touch.

[robust horizon]

@lethal lagoon I'm curious whether you could 3D print the "thread" part too

[sand lotus]

seems like thin flat cable would be more desirable for that design.

[haughty quiver]

"booop boop boooop" @lethal lagoon !

[lethal lagoon]

@haughty quiver yep that's the sound it would make in my head haha!

[robust horizon]

woooooosh @nova totem

[dim wigeon]

I imagine when you’re 3-d printing onto fabric like that, there’s a balance between making the traces thick enough to get a good connection, and being thin enough to not impact the flexibility of the fabric too much.

[lethal lagoon]

@sand lotus yes i think integrating wire will be the way to go with more complex designs

[sand lotus]

ok the new led animation speeds are getting ridiculously fast. ok... jepler and gamblor, get it to run doom.

[rapid hornet]

I think it'd be I2C to the other mcu. Main challenge is making sure you can load new code

[smoky island]

Nice! thanks for trying that out and sharing Mark! It's amazing to see the speed effects a big real world grid like that.

[sand lotus]

seeing projects like this makes me want to plaster entire walls with led strips and just turn them into displays

[robust horizon]

great impact to the demo

Thank you so much @split gazelle !

[lethal lagoon]

yes that's definitely the tricky part! i'm thinking of printing onto a tpu lattice instead of mesh to get more strength in the substrate

[sand lotus]

Thanks for hosting Liz!

[split gazelle]

thanks folks!

[lethal lagoon]

i love the tiles sophy, reminds me of space shuttle tiles in a way, dark carbon tiles.

except they conduct

[nova totem]

Thanks for hosting and great projects everyone! (I may have to rewatch some since I was busy typing away during it!)

[sand lotus]

everyone remember to refresh youtube, JP's up next

[robust horizon]

are there guides to doing that? It sounds like a cool idea

[dim wigeon]

Ooh, neat! I was reading “Structures: Or why things don’t fall down” by J.E. Gordon, and it was interesting to learn that the same considerations which affect the strength and rigidity of bridges and things also apply to fabric.

[robust horizon]

don't start on time, I have to warm up dinner to eat while I watch

[hot frigate]

I guess I'm less thinking about the I2C, and more about the data packets and their respective management on either side. It's almost like a new communication protocol.... loosely. right?

[rapid hornet]

ya, you'd have new i2c command processing for the code on the coprocessor

[sand lotus]

clothes don't fall down because humans are inside them 😛

[lethal lagoon]

@tammy OOH i will have to look that up

[lethal lagoon]

I haven't seen a guide for that specifically yet, so I think i'll have to experiment, but i'm sure ive seen someone do it before... somewhere... I'll have to dig in my bookmarks 😅

[dim wigeon]

@lethal lagoon There was a whole discussion about the balance between tension and compression along the bias axis are the reason why you can’t make good clothes out of paper because it won’t drape properly.

[sand lotus]

that's a neat point

[lethal lagoon]

wow that is fascinating @dim wigeon

[sand lotus]

3d printing can offer rigidity that most textiles can't offer

the whole mesh stuff you're doing sophy has tons of possibilities, i find absolutely fascinating. cutting edge of fashion design, imo.

[hot frigate]

Yeah. Looking forward to hearing more about it.

[dim wigeon]

“The drape of a fabric depends mainly upon its shear modulus, and although, very probably, few couturiers could quote any figures…the lower the shear modulus of a “material” the less its tendency to unwanted creasing. The reason we cannot dress ourselves in paper or cellophane without appearing ridiculous is mainly that these materials have too high a shear stiffness, so that they will not drape properly.”

[haughty quiver]

Hello all!

[split gazelle]

will the later hour affect the power of Lars?

[echo canopy]

👋🏻

[sand lotus]

that's a huge arduino uno in the back, never noticed that before.

[nova totem]

Doesn't the late hour give Lars more power?

[slow spire]

Hahahaha

[cinder wind]

actually a normal sized Arduino, JP is just very tiny

[slow spire]

That’s why they hired him.

[sand lotus]

ask a bachelor, i feel like JP's needs to start handing out roses 🌹

[robust horizon]

if I'm reading this graph correctly, lars's powers are waning at this time of day

[sand lotus]

using the Circuit Playground as a bot platform is a great idea Jay. that was really cool.

[split gazelle]

good, i was worried

[dim wigeon]

I feel like one doesn’t have to be an Engineer to be an engineer. Or maybe, one doesn’t need to be an engineer to engineer things? Something like that. 🤷‍♀️

[slow spire]

He’s mine. And I’m here to win, not make friends.

[smoky island]

I was stoked to hear about that watch device. I got one of the early espruino's but hadn't kept up much with the project. It's great to see a neat new form factor and even better to see on there!

[slow spire]

Yeah, I shifted into hardware years ago, but in many more civilized countries I could not legally use the title engineer.

[dim wigeon]

@slow spire Same. I can’t even use the title “BA”… 😆

[slow spire]

I’m definitely faking the EE part.

Me neither, @dim wigeon !

[nova totem]

I really want one of those scorpio boards

[shell mason]

[sand lotus]

think i can run my entire dragon skull mask on 1 scorpio now cutting down the wiring and batteries inside. definitely going to pick up a couple scorpio boards. and they're 5v out so brighter LED than 3v!

It's JP though @slow spire he'll understand.

[sand lotus]

only for BLE so nrf52840's etc?

ohh i have a couple of those

[sand lotus]

why is there soooo much cool stuff, so many projects not enough time

[cinder wind]

[mellow thunder]

@split gazelle awesome thanks 😊

[sand lotus]

JP's product pick of the week had the LED glasses board a couple weeks ago which are 52840 based too

[split gazelle]

i have used it, can confirm 😺

[robust horizon]

And the protocol is open, so you can also create your own client. If that's the kind of thing you like

[rapid hornet]

[cinder wind]

also works on Seeed Xiao BLE Sense https://circuitpython.org/board/Seeed_XIAO_nRF52840_Sense/

[sand lotus]

S3 BLE still very buggy but when it does get hammered out it's going to be another BLE board... the C3 too.

[cinder wind]

Be honest, @haughty quiver, you just wanted that radio because it can sound like a synth with those SSBs

[sand lotus]

surprised air traffic bands still work on that. some technologies take longer to update than others i guess.

[slow spire]

I had to learn about some of that airport comm stuff for my FAA part 107 drone license

[tulip canyon]

[viral sail]

You can still tune into WWV timing signals.

[slow spire]

I use SDR on the web when I want some shortwave.

[nova totem]

I live almost next door to the airport, can pick the frequencies out really clearly. Even some of the very local ones (baggage handling)

[sand lotus]

[sand lotus]

yeah is there a shoulder strap?

[slow spire]

Nerdy boombox!

[sand lotus]

question about the scorpio. can it do analog LED out and digital (neopixel) out? or only digital? ADC <-> DAC on those pins?

make code is a lot of fun to play with

also something i found recently that someone in discord brought is up is wokwi.com's Pi Pico emulator, works great in circuit python.

[slow spire]

Just started playing with Wokwi. It’s cool

[sand lotus]

great way to prototype small projects digitally instead of on a breadboard. only used it with an LED and a switch but it works great.

[cinder wind]

Yay! I love Wokwi. Great way to test out CircuitPython or Arduino code without needing to pull out a board

[sand lotus]

during halloween that highschool that did the pumpkin projects created entire music scores manually with makecode. creating notation in make code is a breeze.

[clear matrix]

@smoky island Everything ok?

[smoky island]

Yes, sorry. Apparently this had focus instead off my start app search 😅

That does explain why it didn't launch the first time though

[clear matrix]

I wasn't sure if it was that, or a desperate cry for help. 😂

I was typing git commands in here earlier. So I get it.

[brazen grove]

we are live

[modern night]

Hello all! Hope everyone's friday is going well!

[grand tusk]

Hmm, no display.show()? How will that change displayio for blinka? What about the JavaScript port?

[fallow fractal]

question, for your example of having multiple root groups that switch between. -- scene 1, scene 2, ect.

[grand tusk]

okay thanks for the explanation

[fallow fractal]

we just change the property?

do we need to call a method to inform the code there was a change?

yeah. if you have an example that would be amazing. thank you.

[fallow fractal]

are there automated tests as part of the build process?

i know hardware emulation might be difficult in the near term, but perhaps you could use something like a trinkey to run traditional automated tests on.

yeah. send me what you have on discord sometime, i'd love to take a look

[wind spoke]

Hi, for human testing, one way to help distributed testing, if you have code and expected result (picture, audio). And if it is easy to upload that code (like the project download), then it is easy to ask other to help.

[fallow fractal]

perhaps a better question to ask is the 80/20 rule, where are the majority of circuit python bugs? core language features or something specific to an attachment -- display / sound / neopixels ect

[brazen grove]

I think the LED matrix displays use that

oh, no

that was this tablet project!

with an lcd display connected directly to the mcu, without a driver chip

the one you ran a lottery for

[wind spoke]

Bugs in the core affect more people...

Except if this is corner case.

[fallow fractal]

testing the core is easier, because we can just run a bunch of python code and have it write to file after.

check the test results file and see if everything worked

[thorny thicket]

does adafruit sell a esp32 chip that i can use ethernet instead of wifi

[brazen grove]

the matrix led use the framebuffer library, but not framebufferio

it's the framebuffer from micropython

[wind spoke]

I made a few contribution to the ISL, I was suggested to implement pixelbuf ... but I did not knew how to. That was for a Pimoroni multi-pixel "line".

Check the learn guide of that Ethernet Feather to see the usecase and the language that are supported.

ISL#### the library you were looking at.

[brazen grove]

it's using this internally

you will need to assign the root_group in your code to test it, though

[brazen grove]

you can always use incognito mode

or different browser

[modern night]

Thanks for the stream! This is a really interesting addition.

[brazen grove]

thank you for working on this!

[smoky island]

For sure! I am am happy to. It was just barely beyond the scope of what I've done before so it's been a good learning experience for me.

[smoky island]

Good morning! Starting up for the morning now, working on the FrameBufferDisplay code. YT: https://www.youtube.com/watch?v=CWDlGJ0u7fI or Twitch: https://www.twitch.tv/foamyguy_twitch to follow along.

[sand lotus]

Don't know if you saw but I submitted a Twitch & Mastodon API for review. 🙂

Adafruit discord is 🔥 for learning about cool electronic projects.

I missed yesterdays stream and didn't get a chance to watch the replay either. Saw some chat about root_group so figured it's about the display show stuff dishipu was talking about.

I think you'll be proud of me with the Twitch API. It's using a real 0auth bearer token process.

so many boards... which random button sequence gets this one into bootloader mode... i end up doing like 10 attempts before actually getting it from board to board. of course if you don't get it then have to go look it up. happens to everyone no matter the skill level.

i did actually get a 2nd matrix panel. going to port the 7-segment project to the 2 matrix panels. yup.

i love the pink feathers. sad when lady ada said the next revision won't be pink 😦

exactly, i'd love to see a baby blue or torquoise.

[inner spade]

Like the OSH Park “After Dark” board color, too.

[sand lotus]

is that the matte black? i don't know their boards they won't convert easyeda gerbers correctly. can't use them even if i wanted to unless i port my files to kicad somehow.

[sand lotus]

what CP are you running? is that still on a version that had the reset bug or something?

oh beta4 nvm

[inner spade]

Clear solder mask

[sand lotus]

oh wow that's what i keep seeing. now i get it, yeah that's cool.

the gold enig contrast looks great with that too

sharp displays haven't been updated for displayio?

54 is too big for the 1.3" yeah gotta be for the 2.7"

when working with a new screen i move everything to 0,0 it's easier to push stuff out from there instead of guessing how much minus to make something.

possible with the new ulab and speed optimizations to make displays run faster or is that still bottlenecked by the SPI bus speed?

jepler, gamblor, todbot have all shown some new code recently for LED speeds, unsure if that'll translate to displayio.

aren't displays just rgb leds though? that's where my brain was going with that.

ahhh that's why new labels spawn off screen. the anchor point. never realized that explains it.

[inner spade]

Conceptually, but the physical rows and columns are different per display. Then there’s how each pixel is refreshed — technology dependent.

[sand lotus]

thought danh said root_group change wasn't going to happen until 9.0, how is it already supported?

or is this just about making a core root_group name kind of match up with a displayio root_group?

ah ok, cool that's it's starting to happen quick. whew life moves fast sometimes.

are there any different features between root_group and show or just a name change?

in programming that's called verbose

verbosity, stems from the word verbatim i suppose.

no just saying in general that verbose means "output exactly as i see it" or in the case of a verbatim quote in the news it's the exact thing someone said.

[inner spade]

from adafruit_matrixportal.matrix import Matrix

Instantiate and blank display

matrix = Matrix(bit_depth=6) # default is 2; maximum is 6
matrix.display.brightness = 0

(sorry, no backticks in this phone)

[sand lotus]

that right there is why i started on the api examples. working with portalbase or matrix portal imports so many libraries that might be unnecessary. basically, bloated.

[inner spade]

Bit depth dramatically impacts refresh buffer size

[sand lotus]

ohh you actually switched displays to a matrixportal. rip, nvm.

yeah true

but i was the beginner and trying to get something working on matrixportal or portalbase was kind of a nightmare. actually has the opposite effect of being easy to use for a beginner.

if it was easy i would have never written the api examples

[inner spade]

If the MatrixPortal is set to high brightness and is underpowered, it can cause the file system to wipe.

[sand lotus]

wait what

wow

that's good to know because i ordered a 2nd panel and intend on trying to run both on 1 psu

[inner spade]

Need to supply lots of power via usb when the display is bright.

[sand lotus]

oh one thing i've learned about the matrix is if you don't plug in the 5v supply it only displays in red, forgot to plug in the external psu when i first got it, learned that one the hard way.

[inner spade]

That’s a Matrix Portal issue cause the MPU and display are on the same power wire.

[sand lotus]

oh i have a rgb matrix featherwing, not matrixportal, paired to an S3

[inner spade]

That’s why I blank the screen as soon as possible then put PaletteFader in place. The matrix.display.brightness is only binary; 0 and 1.

[sand lotus]

i can scroll back and look for you

hard to see due to the window layout but looks like it was mostly empty, can't see in the lib folder but main directory only has code.py as far as i can tell.

[inner spade]

PaletteFader was proof of concept for changing the rgbmatrix core module.

0 is off

A full red display suddenly draws a bunch of current. A roll of the underpowered dice.

[sand lotus]

because i figured out it only shows red when on usb power my guess is the red showing up is during reboot and it turns on/off the 5v supply?

easier for me to know that since external psu isn't tied to the feather with the rgb matrix featherwing?

when i hit save with the featherwing it does a bunch of weird stuff showing random lines and stuff, then resets, and everything reloads fine... most times. sometimes i'll get a hard fault because i'm using an s3 which has hard fault issues still.

[inner spade]

During the reset sequence, the attached matrix is under its own random control, at least until CircuitPython starts talking to it. Perhaps the MatrixPortal build should have display blanking as a priority during startup.

[sand lotus]

from my experience it's not like a TFT and displayio, there are artifacts most times on the panel before resetting to black.

[inner spade]

Yeah, TFTs don’t draw more power when they’re all white.

The matrix panel isn’t very smart, just fast.

[sand lotus]

here's what mine does when i hit save

rgb matrix featherwing + s3

[inner spade]

Same pattern each time?

[sand lotus]

also if i unplug the usb cable to the feather it does keep the image on the screen, unsure if that means it crashed.

haven't used it enough yet

yeah kinda fond of the glitch effect lol

no different patterns each time. i think it's actually the fonts getting stretched or warped. only theory i have so far.

[inner spade]

Appreciate the stream. Thanks!

I see the glasses are clean now

[cinder wind]

oh no JP is moving faster than time again

[echo canopy]

Question.. I k is it’s meant for a display to MCU….. what’s the max current you think the mini lines can handle if I just want to do a quick GPIO connection? For semi permanent set up

Okay under 300 mAh or so ?

[carmine lance]

unrelated to this device, but will the barebones macropad be coming back in stock anytime soon?

[rotund marsh]

Curious about max current too, datasheet for fpc connector would be nice. Could use the connector for other non TFT scenarios.

[cinder wind]

these FPC cables are essentially the same as the Raspberry Pi camera connectors, so any datasheets you can find for them will apply to these, wrt current & voltage

[drowsy inlet]

Q: does the cable need to be oriented a particular way?

[earnest cosmos]

EyeSPI is very cool - I built a little FPGA board that uses it: https://github.com/emeb/ice-dongle

I wish that the EyeSPI capable displays would break out the rest of the pins (the I2C, GPIO, etc) to 0.1" header so that one could hook to them.

[drowsy inlet]

thank you for the answer

[clever summit]

Looks like FPC cables can be used up to 200 milliamps.

[cinder wind]

that sounds about right

[clever summit]

Most datasheets don't even tell you.

[rotund marsh]

Off topic, but someone mentioned Macropad... For some reason, earlier today, was day-dreaming about Macropad with PicoW/esp32 wifi and battery 🙂

[inner spade]

I still struggle to figure out how pixelbuf translates to an RGB matrix. That's the pathway to controlling RGB matrix brightness since it's not provided in the hardware via the HUB75 interface.

Need a block diagram of how the "buffers" interface between displayio and the hardware.

If you ever run across a description of the displayio architecture, I'd be forever grateful.

[inner spade]

Dinner time here. I'll catch the remainder on VOD. Thanks for streaming today. Always a nugget or two in there.

If could just confirm that something like strandtest works (or not) with NEO_KHZ800 on the vintage pixels, that’d be super helpful.

[smoky island]

Cool goggles! 🥽

[teal river]

@sand lotus Can you control the brightness and strobe/fade? An RGB version might be helpful for, say, differentiating different response teams, and brightness control would be helpful to reduce battery usage and not blind people when you're in front of them

Now let's go see if I can find those ancient NeoPixels

[sand lotus]

@teal river Yes you can control the brightness with voltage level, i just have it on a rotating fade effect. it's customizable in the same way a normal non-addressable LED is.

[teal river]

Is it a strip of single color, or RGB non addressable?

[sand lotus]

I used it with a 10,000mah battery and it lasted 4-5 days non-stop

[teal river]

Noice

[sand lotus]

2 single color strips

noods. they don't come in RGB.

[teal river]

Ahh

[sand lotus]

https://www.adafruit.com/product/5507

a tiny 350mah battery lasted about 5-6 hours

[teal river]

Not bad

[teal river]

I might have misremembered — just grabbed what I THOUGHT were original NeoPixels, but they’re Flora v2, and specify the higher mode

[sand lotus]

my particular setup doesn't have a potetiometer for brightness but definitely possible yes. the BFF charger has a tiny on/off switch

[low fractal]

No worries! Thanks for looking into it.

[sand lotus]

paint your dragons story on the neopixels was fascinating... what are the implications if any for more recent neopixels?

would have asked earlier but i literally couldn't see through the fogged up lenses to even read chat lol

[teal river]

Sounds like it just means a little saved space on code now, and the sticking realization that we could have gotten rid of the lower speed ages ago XD

[low fractal]

No implications for newer pixels, just means a fair bit of ugly code can be stripped out of the library. Less to maintain going forward.

[teal river]

Less to maintain and no function lost is good!

Question: now that i have RGB step switches it takes 4 pins per step switch. I'd like to keep the rainbow PWM capability. Is there an I2C LED driver for 16 step switches someone can recommend. 16 x 4 = 64 pins. This is for the TR-Cowbell. I only have about 8 pins available on the Pico for it so I2C probably required. 😖

[teal river]

Question: I got a couple power inverters from Amazon with this very saw tooth looking wave — they’re supposed to be “modified sine wave”, and one box shows a stepped square wave, not… this. Do you think this is likely to damage something without filtering the waveform? A quick PC power-on test resulted in loud buzzing from the PSU, and I was afraid to run it longer!

[tulip canyon]

Hey Phil, took me a while but running Arduino V1 IDE with a Flora, the WS2811S Neopixel does NOT work with NEO_KHZ800

[teal river]

Don’t deafen yourself!

[sand lotus]

i feel like this needs to be improved to be more beginner (don't have an oscope) friendly.

[teal river]

I think this part is just to visualize for demo purposes

[cinder wind]

The Arduino IR library is good for capturing and decoding these IR remotes

[sand lotus]

Question: I have a cheap PC PSU that seems to show direct continuity between the voltage rails of the 24 pin, CPU 8 pin, and PCIe 6+2 — that means I can just tie it all together as one rail to maximize output for a bench PSU, right?

My dad has been using his ancient Samsung Note 2 with an IRBlaster as a remote, so this would be helpful to replace that when it dies

Is it just me, or is the feed jumpy/laggy?

[sand lotus]

@teal river umm not sure if i'd mess around with a PSU like that. unless you're following a guide that covers doing it safely that could be dangerous.

Since the NES doesn’t talk to the controller, I think the only “delay” with that device is the time it takes the light to travel to the console… which is obviously negligible XD

@teal river the showtimes are also in the pinned messages for this topic. oddly the pinned message doesn't match the showtimes. showtime command has been updated with recent changes but the pinned message has not. might need a moderator or admin to fix that. i'm not sure who to tag @clear matrix perhaps.

if dynobot has the latest updates then would probably be best to put a list of dynobot commands (such as showtime) as the pin instead of the lineup.

[teal river]

I always forget it’s pinned anyway XD

The pin is just a showtime command result anyway

We have many ways to peel the potato in hacker town!

[sand lotus]

yes but i always forget the command. is there a list of commands for dynobot somewhere?

[teal river]

Not sure… showtimes is the only one I really use here, and I just forget the prefix, lol

[sand lotus]

same, which is why i think it's a good idea to at least put that 1 command in pinned for this topic.

[teal river]

[teal river]

Hi hi!

[inner spade]

One works with addressed LEDs, the other is for matrixed LEDs.

Addressed LEDs have built-in pixel memory. They hold the color/brightness setting, not requiring continuous refresh from the microcontroller.

[teal river]

Websites can lead to anything and everything

CircuitPython website?

Plots a Pico W webserver

If you aren't digging into someone else's old code, you're doing it wrong :P

NeoPixels are blindness-makers

https://tenor.com/view/iron-man2-reactor-tony-starks-rdj-gif-14235105

[inner spade]

Recent streams have me thinking about writing a circuitpython helper to add slicing functionality to displayio.palette and .group. Proof-of-concept to see if that can help when using ulab. Thinking that it could improve performance for managing animated display objects. Have a hardware project to complete first, though.

[teal river]

Yay compiling!

RIP Foamy eyes

It's still glowing your whole face, lol

Personally I keep my NeoPixels either turned away or covered up

Facebook, yuck

[inner spade]

Is root_group really a group or just a layer?

Can you append to root_group?

Like with other displayio.groups?

[teal river]

Try saying root_group 10 times fast...

[inner spade]

It’s confusing to call it _group if it doesn’t act like a group. It’s really just a container for the currently visible group of I’m understanding it properly.

Conceptually it appears to be the pointer to the group you want to display.

Can you show the properties of dir(board.DISPLAY.root_group) before assigning a group to it?

Cool! That means you can append a bunch of groups in there. Thanks for indulging my curiosity.

[teal river]

Oops, profane comments…

[inner spade]

board_init.bootloop = False 😬

[teal river]

Would be nice if it could break itself out of a boot loop the way a PC can break itself out of a boot loop from a bad overclock after a few failed boot attempts

[sand lotus]

could it be coming from &circuitpython_splash because of the ampersand?

meaning something else is injecting into the splash other than the 1 thing you're expecting?

my understanding of ampersand in c is breaking out a variable to be used in another function. they can be dangerous if it's being used elsewhere and now you've got multiple things going into it.

usually you'll get some errors for unexpected arguments or stuff like that, you're not getting that though. so either it's really sneaking in there somehow or is that not even the issue at all.

and there ya go, it was actually sneaking in there from somewhere else.

what would you do there? do else for everything and give them unique else prints?

[teal river]

Dinner time

[sand lotus]

returning false without understanding if that's actually the problem is a shot in the dark, not the best way to go about it for something as severe as a hard fault.

[proper prawn]

Thanks Tim. Bye to y'all!

[sand lotus]

well that's basically how i am in trying to learn circuit python like everyday. glad i'm not alone in that lol.

[teal river]

What exactly is a hard fault again?

[sand lotus]

yeah circuit python is pretty amazing for that. you can basically set it on fire, hit it with a hammer, hit reset and it's fine. 😛

equivalent to a blue screen of death

[inner spade]

Oh how nice it would be if other operating environments were as bullet-resistant as CircuitPython. Haven’t completely bricked anything yet — and I’ve been trying.

[sand lotus]

yeah i have 20 boards, i'm a horrible coder, and i haven't been able to brick a device. +1 circuit python.

[teal river]

Sounds like an exception is like a BSOD but hard fault is an outright black screen crash/reboot

Except it doesn’t reboot

[sand lotus]

yes, that's a better analogy.

[teal river]

I too have failed to brick a CP device via software… I even tinkered with my own CP builds

What did we see now? I feel like I missed something…

[sand lotus]

looking forward to you picking this back up tomorrow morning. i do enjoy coffee with foamyguy.

You’d said something about YouTube filtering and I was confused XD

[sand lotus]

oh just some chat spam in the youtube feed that went un-auto moderated by youtube

[smoky island]

Ahhhh, I was grumbling about YT's lack of filtering of blatant spam.

[teal river]

OHH, I missed the spam… can’t read the YouTube chat on stream on my TV and wasn’t looking at the app

Gg YouTube

[smoky island]

We get very obvious spam bots that post in the chat. I've been trying to figure out a way to moderate it without the messages showing on the stream. I tried something a bit different today thinking it would help, but it was not nearly as helpful as I had hoped. The messages remained visible even after deleted / reported by mod.

Good morning Tim and all online

[teal river]

HCT245... Octal bus transceiver... seems like it's used in multiplexing?

Yay working display!

[grand tusk]

yay!

[sand lotus]

yes multiplexer chip, probably i2c

i think most of the samd21's adafruit's been using are g18, not a big deal

don't know about the at19 though

when i installed WSL Ubuntu and all the adafruit stuff it always complains about needing arm-none-eabi-gcc because I'm on x64 AMD

which isn't included in the board make guide

oh thought it was related for a second. gdb sounds close derp, it's gcc

you are not a person... yeah might want to read the rest of the sentence 🤣

[teal river]

I dunno if you'd be allowed to work for Adafruit if you were a terrorist XD

[sand lotus]

once your designated a terrorist i don't think you're allowed to have an occupation or at least not in the US on a payroll. that would be awkward.

[teal river]

indeed

[sand lotus]

so i take it that parts not in the guide...

[teal river]

I assume if you say "no" there's a way to do it later

But you know what they say about assuming,.,,

[nova totem]

Still trying on the ESP32S2 or trying on a SAMD51 first?

[sand lotus]

yeah when it comes to firmware assuming can be really bad

so am i. i've never used one of those before

[teal river]

Often in PC BIOS updates, which can brick things during application, a good rule of thumb is "don't update unless something is already broken"

[sand lotus]

yeah i think trying to use it as it is, is a smarter way to go, if it doesn't work then update.

[nova totem]

Makes sense. I can't recall if I tried it on a SAMD family or a RP2040 cause it is the same processor family

[sand lotus]

i think the last thing you did to stop that was actually to do the return false or something like that

11 months ago Circuit Python troubleshooting with GDB https://www.youtube.com/watch?v=rqFm-D51UL8

i've done that a couple times with my own car videos. i was just like nice, thank you past self. recording things does actually come back around to help yourself sometimes.

[teal river]

I have confused myself with a transistor XD not working, and then I tried rewiring the button and the LED lit when I touched the base wire.... not doing it now...

[sand lotus]

that's exactly the reason i started recording myself and making youtube videos. it wasn't to help others. it was to help myself in the future. oddly enough the videos started helping a lot of people which was just a bonus really.

like masking tape and plastic bags are great when taking apart an engine but video showing everything you're doing can't be beat.

coding with iterations can sometimes be a lot like that

yeah anything with j-link definitely a dev level question.

[nova totem]

Maybe all the symbol names are stored in the .text area? Wild guess. You could look in the linker script (which is an area I have little experience with)

[sand lotus]

clean ftw

i don't know what libncurses is but it doesn't sound very pleasant.

i've used nano once... once.. so now curses makes more sense

🎉 and you're in, nice one. i would have spent hours pulling my hair out trying to figure something like that out.

[nova totem]

Yeah I believe they are separate

[teal river]

I use nano when that's what's on a computer

[sand lotus]

guide needs better wording on that

ah you have to initialize the middle man before running the program, makes sense.

[nova totem]

Not to pull your brain out of this but I figured the _pixelmap range problem (occurred right at the first out of bounds address). I could try to push a commit to that PR or just comment on the two lines that need to change.

Never tried to push it, I'll figure something out 🙂

Yeah

I was using gh to pull it... and hmm yeah the way you are describing it I will just comment on the PR. Going to look into the slice things too, since I was the one who wants it

[teal river]

Transistor is making me sad #help-with-projects

I can never remember the commands to show USB serial and connect so I just up arrow all the time XD

[sand lotus]

yeah sometimes i'll up arrow 50 times if the line is really long

[teal river]

same, lol

[sand lotus]

Using a debugger is way harder than I thought it would be, or should be.

[zenith grove]

try setting a breakpoint to the hardfault-handler with „break HardFault_Handler“ and then „run“ to restart circuitpython…and then do a crash via code.py..and then „bt“ for the backtrace

[inner spade]

Debugging wardrobe protocol: red T-shirt.

[sand lotus]

Is adding a breakpoint designating a specific area to observe?

If it’s in order of memory trace would #2 be the last thing run before hard faulting?

well then.

Maybe it’s all related?

[teal river]

My cat is behind me while I work and listen

[sand lotus]

Honestly I’m hoping for a silver bullet fix to all the hard faults happening lately. I get them on my s3 constantly, um feather s3 too. The s3 in particular is plagued with them right now.

[teal river]

He got up, so here’s more stripes!

He collapsed from exhaustion

[sand lotus]

Yeah this hard fault muddy the water for the other. Are they connected? Who knows. Kind of at an impasse here.

[teal river]

He got up, walked to the sun, walked back, and was out of power, lol

[sand lotus]

Pretty sure lady Ada did an episode of desk of lady Ada where she goes over the differences in the j-links.

[teal river]

In my experience, usually $1 devices do not work the same as $450 devices

[sand lotus]

https://www.youtube.com/watch?v=gBJ-edSiIV0

on the s3 i have that's hard faulting i regularly see it do stuff like that where it just stalls, sometimes forever, and then hard faults. like it gets caught in a loop and just churns.

[teal river]

I can now turn on a PSU with a transistor!

[sand lotus]

just had a weird idea. could it be related to terminalio.font missing characters? have you tried with a custom font. i know it's a long shot.

i've heard built-in terminalio is a slimmed down version of a full font

[inner spade]

Nice reasoning. Font object handling is imbedded in the micropython core, if I recall.

[sand lotus]

just looked at my bug report for the S3 hard fault and i'm actually using all custom fonts in my example code.

oh wait nvm, no i'm not, half of it is terminalio

https://github.com/adafruit/circuitpython/issues/6791 might be worth a look just to see if there's any correlation for you.

would the bytecode be terminalio font bytecode or something else?

yeah i revisited it on beta 4 nightly build, not a custom build, not sure if a nightly qualifies as custom

been an issue since 7.3.3 on the featherS3 specifically for me actually, been unusable since i bought it.

that's a good idea, will test that out tonight.

i never was able to drill it down to a specific culprit, i was thinking it was wifi related but maybe not now.

been dealing with this while the S2 and even the Qt Py s3 are fine. it's specific to the S3 but i dunno, was kinda hoping you ran upon the same issue, why i said would be nice if all the hard faults are related. so i could actually use my S3 for once. 😛

you also disabled the audio modules

like that epic bug cgrover found that ended up fixing a bug no one knew was there on 30 boards in one shot, just epic.

[safe carbon]

I once roasted a bread board by putting 120v AC through a 1/4 watt resistor with far too little inductance to reduce the current sufficiently. Not only did the resistor burst into flames, it also melted a hole in the bread board. I mourned the damage to the bread board, though I still have it somewhere...

[teal river]

That sounds exciting, as Big Clive would say…

I’ve never done AC stuff on a breadboard and I’m afraid to try XD

Mains AC anyway… I wanna try making some AC generating circuits for funsies

Very very low voltage…

[safe carbon]

Yeah, I don't recommend mains power on a bread board unless you really know your math and have gone over it lots of times. It happened when I was much less experienced and didn't have a good grasp on inductance. Also, my inductor core was steel instead of soft iron, which made it worse. I could probably do it right with my current level of experience, but I've never tried it again.

Low voltage AC isn't too bad, but you can still get shocked by it. I worked at a hardware store years ago, and I discovered that 12v AC can zap you. It doesn't hurt much, but it's really startling when you don't expect it. I have a ~5v AC generator I made, and that isn't enough to get zapped with though, so there is a limit.

(The hardware store sold 12v lighting fixtures on bare rails. That's how I got zapped and why working there is relevant. I was cleaning the displays and accidentally touched the rails for one of the fixtures.)

[teal river]

I hate AC sometimes, lol

[safe carbon]

Yeah, it can be really cool, but it can really bite you when you aren't expecting it, and not just in terms of getting zapped.

[teal river]

Burns… also not fun

[safe carbon]

Also inductive coupling. And phase stuff can be weird.

👋 didn’t realize you streamed yesterday. I missed you actually figuring out the debugger! Watched it last night. So awesome you got all of that voodoo figured out. Did you ever figure out the cause of the hard fault?

https://youtu.be/ruV0zUYCLM8 Foamyguy funday Monday stream

I didn’t understand the difference in pixelmap vs Python pixelmap, confusing using the same for 2 different implementations.

A split means the strip could be n length. Might be 10 pixels or 300

Ahh that makes sense. For size especially on m0 etc… space is always at a premium.

Have some things to take care of. Will catch up on the rest of the stream tonight. again congrats on figuring out the hard fault that had to feel good. 👍
