Today I am fighting with Tasmota. It insists on loosing all settings if I power cycle it. Frustrating.

[sand lotus]

Good morning. Been a while.

[open surge]

👋

[smoky island]

I am getting started for the morning now working on preparing a library for the community bundle. You can follow along on twitch: https://www.twitch.tv/foamyguy_twitch or YT (linked above)

[sand lotus]

7-color epaper? didn't know they had that many colors yet. neat.

[clever summit]

Tasmota is a IOT firmware for ESP32.

I use it for my smart home devices.

[ancient grotto]

Good Morning

[sand lotus]

I heard about that I think in the meeting? That sounds like a great use. Did you write a learn guide on that?

Ahh you can ping yourself on discord with it. That's smart.

i think deshipu's first platform was the pew pew

the M4 was/is the most powerful that is compatible with makecode game. we're well past the M4 now but makecode still hasn't supported different MCU's.

one of the nice things with ugame or stage is it should run on any circuit python device. not limited to an M0 or M4 MCU.

makecode gaming got a lot of support because it was made with blockly so a ton of kids were making games with them.

GameCon?

what was the nintendo games you were porting? the octopus platform?

could add that in there

game & watch would be so generic as a keyword. they could have named that platform better.

saw your book cipher videos, they were great. i'm trying to take a break from cryptography, kryptos fried my brain.

the featherwing itself is just a display. i don't think it has buttons or controls. the magtag does.

oh nvm i was thinking of the TFT featherwing.

tft featherwing has an sdcard port

ah right because theres no controls with the tft featherwing and it's too big

i can do that but i use the ST7789S with an adapter

[brisk bone]

I did something like Adafruit tripler for Feather and 3x 1x4 NeoKeys, simple, but much more elegant than connecting everything using cables

[sand lotus]

that sounds more up Deshipu's alley with the game controls though.

i can look into what it would take to add a thumbstick and some buttons.

[sand lotus]

Problem is that I don't know how to directly add a display to a PCB. My adapter is basically a featherwing adapter.

[unreal bay]

Did I see you had a qtpy feather Pico translator/adapter plate?

[sand lotus]

Here's a version where you can use either a Pico, QT Py, or Feather with the display.

yup, if I could just figure out how to put the display on I could eliminate the intermediary board.

[unreal bay]

Cut a hole for display cable and duplicate everything in the TFT board initially? I'm no PCB wizard, just throwing out what I'd try

[sand lotus]

I've never seen behind a display. No idea what connector it needs. I'd have to destroy one just to look. There aren't any guides on that kind of thing. 😦

[unreal bay]

There are schematics for the display boards sometimes, or the tft feather wing shows the connector I'd imagine

[inner spade]

With Eagle or KiCAD, it’s fairly simple to use LadyAda’s Eagle project designs, including schematics, board layouts, traces, and footprints to build new designs. Haven’t done it with a display component yet, but it’s on my list.

[sand lotus]

Would need to find the bare displays and connectors.

[inner spade]

Adafruit also sells bare displays.

[sand lotus]

I use dashes for timestamps. Not sure why underscores are more prevalent. I think there's one circumstance I've run into where underscores were mandatory... like with github naming something.

[sand lotus]

Right but the whole reason I made it to begin with is because they didn't have any TFT Featherwings in stock for about a year. So I set out to make my own.

there was a thing called the great chip shortage. 😛

Another great cookie cutter project. I'm out. Have a great weekend. Playoffs tomorrow if you like sportsball. 🙂

[inner spade]

Super! Updating the library list is usually the step that I forget to complete. Thank you!

The bundle process builds the .mpy from the release .py

[unreal bay]

Here's one I meant to ask you Tim, is there a BLE gamepad library for Circuitpython, or the supported services? Wanted to reuse a PS4 pad for something but not via Arduino

Yeah was thinking of making usb to ble adapter with usb host

[inner spade]

When a chip’s register needs to be accessed, you’re probably in “driver” territory.

[unreal bay]

[tropic wasp]

What processor will you use for the displays?

[open girder]

@tropic wasp really any, but we're using a rp2040 for this for now

[shell mason]

very cool screens

[tropic wasp]

Lady Ada can you touch on the differences between the GC9A01 and the ST7796?

[open girder]

@tropic wasp they're very similar, but from different companies. the GC90A is for smaller screens: 240x240, the ST7796S is for 320x240

[sand lotus]

I just missed it. 😦

@open girder https://github.com/DJDevon3/CircuitPython_ST7796S I've already made a driver for it. This is the display I've been using for my adapter boards! 🙂

[open girder]

Espressif programmer test success! 💻✨🔧

While developing boards, there are oftentimes we want to program ESP chips without going through the onboard USB port; this adapter will help us (and others) do that! It has a CP2102N USB-serial chip (https://www.digikey.com/short/bm7n3p5z) with RX/TX signal LEDs and two transistors wired up to the DTR/RTS line for the 'esptool standard' reset procedure technique. The output IO, plus a 3.3V 500mA regulated output, is available on a socket header, so you can plug wires in for quick programming and debugging. You can use this for everything from an ESP8266 up to the ESP32-P4! Here, we are testing it with a HUZZAH ESP8266 breakout board (https://www.adafruit.com/product/2471), one of our first Espressif chipset products.

[sand lotus]

The ST7796S that I use is 480x320. Sure about those dimensions? It's the same size pixel dimensions as a 3.5" TFT Featherwing. It's a great alternative to the HX8357. I have resistive touch working on it too. I don't pretend to be great at writing touch drivers but it does work.

[gritty falcon]

[viscid bolt]

Hello!

[cinder wind]

Got mine!

[ivory flax]

Can you make a clock display using ESP32 using a 8 channel multiplex chip 74HC4051. I noticed there is no rest pin. Using 4 of these display

[split gazelle]

oh there's clocks

[merry oxide]

Liz you rock!

[cinder wind]

JP, what’s the nice font you’re using for your clock?

[split gazelle]

i was able to get 4 displays going with a metro esp32-s3 in arduino

[smoky island]

It never occurred to me that you could connect multiple displays on the same bus to create duplicated outputs, neat trick to keep in mind!

[robust hemlock]

Can you connect multiple displays to one microcontroller with circuitpython and show something different on each display? For example if you define each display using different output pins for CS and DC could you address each display separately?

[old surge]

Well, domo arigato, Mono Roboto

[old surge]

I look forward to seeing a set of these run your flip clock library

[smoky island]

by default circuitpython is built with support for only a single display. There was one device that had 2, and theoretically you could create a custom build that should support 2 I think, but it's not tested recently or at all with this hardware specifically.

[clever summit]

Hey Tim!

[split gazelle]

yeah only one display in cp but you could (in theory) make a framebuffer and blit it. it's a little over my head at the moment but i want to try

[cinder wind]

I do dual round displays for my Halloween stuff a lot. Eyes!

[smoky island]

Nice! eyes is what came to mind for me as well

[viral sail]

Thanks @haughty quiver

[vagrant flax]

Thanks JP!

[haughty quiver]

thanks very much all!

[lyric frost]

Thanks JP!!!!!

[cinder wind]

No need to recompile CircuitPython for multiple displays then too 🙂

[inner spade]

Thanks!

[old surge]

Thanks, JP!

[smoky island]

Thanks JP!

[wind spoke]

I was wondering if with CS (Cable Select?) it would not be possible to have one bus, and one GPIO by display to decide what display listen to the bus.

[haughty quiver]

thanks all

[wind spoke]

So supporting multiple screen... not sure how that would work with displayio, but it would be the same frame buffer, and you change the content for the display you want to control.

[sand lotus]

It's been years and I still have almost no idea what PIO is and or how to use it.

[cinder wind]

PIO = Probably Input, or Output?

[haughty quiver]

haha

[sage aspen]

I think it's like Peripheral In Out

[sand lotus]

that's honestly not far from how i think of it. it's a mystery thing that people talk about to do things.

[tropic wasp]

Programmable IO

[sage aspen]

Yeah, that's what it is

[robust horizon]

https://github.com/adafruit/Adafruit_Blinka_Raspberry_Pi5_rp1pio

yes, programmable I/O

[sand lotus]

how is that different from GPIO?

i need a learn guide to explain all of it or something.

[tropic wasp]

I have a pico on the desk that is blinking some LEDs and the CircuitPython REPL is still available.

[robust horizon]

@sand lotus there are multiple tiny, limited processors that interact closely with the GPIO pins

[tropic wasp]

LED is driven off of PIO 0.

[robust horizon]

the programs can have up to 32 instructions total, very tiny, but enough to do things like drive neopixels if you make them carefully

https://learn.adafruit.com/intro-to-rp2040-pio-with-circuitpython

[nova totem]

And PIO can drive it all fast, basically at full clock speed. Faster then you could send information to GPIO

[robust horizon]

the image in the title card gives an idea of what a pio program looks like

[cinder wind]

You know how microcontrollers have built-in hardware units to do UART and PWM? And these operate much faster than if you were to do direct GPIO pin twiddling. PIO is like those built-in hardware units, but you can "program" it with a tiny language

[tropic wasp]

Andd the instruction set is very lmited too, but with some creativity you can do a lot.

[dim knot]

[nova totem]

@smoky island you could make a real cool "race start" lights with those lights (I watch too much F1)

ah nvm misunderstood what you said

[timid plover]

( that's what I'm doing now 🙂 )
experimenting with semihosting

FYI: semihosting prints through a breakpoint to the debugger host

[glad mortar]

yea 24 and 25 would be SWD, if you are okay with soldering it would be possible to add some bodge wire to it, the QFN is not that terrible to solder to

[timid plover]

I battled cmake on windows command line too and used the same trick )

[glad mortar]

yea Zephyr needs a very recent cmake version, they tend to include very new features

[unreal bay]

so if we pull your zephyr branch then windows is a go?

[eager matrix]

I say this recently and it might be a nice war to connect to the debug pins. https://hackaday.com/2025/01/27/diy-probe-clamps-to-ease-your-pcb-work/

[glad mortar]

It works otherwise very well on Windows for me

[timid plover]

here is what I did

+# this helps link and compile with long command lines
+set(CMAKE_C_USE_RESPONSE_FILE_FOR_OBJECTS ON)
+set(CMAKE_CXX_USE_RESPONSE_FILE_FOR_OBJECTS ON)
+set(CMAKE_C_RESPONSE_FILE_LINK_FLAG "@")
+set(CMAKE_CXX_RESPONSE_FILE_LINK_FLAG "@")

[timid plover]

which generator does your cmake target ( I was stuck with unix make on cygwin )

I figured ninja would be better 🙂

[glad mortar]

Zephyr uses ninja everywhere afaik

yea you can in theoery target something else but I think Ninja is the only one that is actively supported by the project

west build is I think just calling "ninja", west flash calls ninja flash and west debug ninja debug

[timid plover]

you've beein in CI - continue the build

[shell mason]

ninja

[timid plover]

so what checks to the pre-commit checks do ?

( is that what you just fixed? )

if you get the build going - you will buy yourself a new test person in NYC 🙂

[glad mortar]

EXTMEM is external memory controller, like the QSPI on the RP2350 or on ESP32

can be RAM or flash

depends on the board you have

marketing blip says
"Flexible external memory controller with up to
32-bit data bus: SRAM, PSRAM,
SDRAM/LPSDR SDRAM, NOR/NAND flash
memory clocked up to 100 MHz in
Synchronous mode"

the discovery boards lists
"512‑Mbit Octo‑SPI NOR flash memory
128-Mbit SDRAM "

both I guess heh

those two should be the two extmem slots

why not?

yea how I understand it the memory controller is an extre peripheral that uses the ocotospi as the phy and is then responsible for mapping the memory into the address space

but you could use the octospi for application code too and then use use it for general comms instead of memory

[timid plover]

is octospi like twice q-spi ?

[glad mortar]

yea

SPI with 8 data lines

lol I have not seen 16 yet, that gets silly

thats a parallel bus at that point

the STM32N series with the hexadeca SPI is nuts, it even has an h.264 encoder?!

Arduino Giga R1 would be cool, is also an STM32H7, should not be too much to add if you got the discovery board working

Portenta may be the same MCU

I think same same just giga is in Arduino Mega formfactor

[timid plover]

when CP is built for these dual core systems like Portenta, what is running on the smaller core?

[glad mortar]

it will depend a lot on how they are connected I guess, if there is no internal highspeed bus it will not be very usable that way probably

You would have different binaries in any case for sure

that seems quite decoupled, probably more suitable to signal across but not full on cross core multi threading

like have a rendering task on the M7 and CPY on the M4

[timid plover]

@rapid hornet - how did the build errors not show up at first ?

[glad mortar]

I was more thinking lvgl on the M7 f.e. and CPY telling it what to render and draw to screen. The ART GPU and display DMA is all on the M7 matrix and the USB is on the M4 matrix. Dunno what the penalty is of accessing these peripherals through the AHB or if you even can address them from the other side

[timid plover]

was that really 63 M bytes free ( flash? )

[glad mortar]

yea SMP on the RP2 would be really cool

[timid plover]

how do you tell make html to ignore zephyr docs?

[glad mortar]

speaking of SMP, the other SMP (MCUmgr) would also be really cool for CPY for Bluetooth targets

you can have a shell over BLE and upload and download files to filesystem etc

and firmware update

Nordic has a good app for it to poke around with, there are also some web versions

[steady osprey]

I'm getting a Portal Matrix S3 and hoping to run code on both cores

I'm using Arduino

[glad mortar]

right I keep forgetting that I can interact with CPY over WiFi

[timid plover]

https://www.adafruit.com/product/5778 is out of stock ?

[glad mortar]

maybe needs more advertising 🙂

[steady osprey]

I'm building a replacement for Tidbyt which was bought out and aren't selling any more devices.

Might be cool to chain two 64x32 matrices together...

[glad mortar]

it is! I should use it more often, I only gave it a quick spin long ago

A VScode extension might make it more readily usable

I think my issue was the limitation of the web editor

yea took me while to switch to it from Sublime, I get it

[timid plover]

I'm assuming the ra8 will be a top secret discussion 🙂

[glad mortar]

I do my early bringup prototyping with CPY usually before switching to nitty gritty C land

[timid plover]

now that you are mentioning pull request - are you seeing the light at the end of the zephyr tunnel ?

[steady osprey]

I tried using protothreads on my Arduino project and it turned out to be a waste of time. Should have just built a state machine or something.

[nova totem]

Who would pick up a new port and add stuff to it, oh wait... 🙂

[glad mortar]

wth that sounds cursed

[steady osprey]

yep, that's it

[timid plover]

two bytes per thread? ( that's pretty lightweight 🙂 )

[glad mortar]

I'm glad that Zephyrs Kernel keeps this all very opaque and just works, I don't want to know the details of how preemptive threading works

[hybrid kernel]

I found protothreads easy to understand but I was using it with pico-sdk.

[glad mortar]

you are much more low level than me too though heh

I don't ever work on scheduling

having preemptive asyncio in MPY/CPY would also be really cool even without any multi core stuff

[timid plover]

desktop or it didn't happen 🙂 JK

[glad mortar]

have a great weekend

[smoky island]

I am getting started for the morning, working on Pi 5 with matrix panels. You can follow along on twitch: https://www.twitch.tv/foamyguy_twitch or YT: https://www.youtube.com/watch?v=B83nx251Wlk

[sand lotus]

good morning ☕

[clever summit]

🇸🇪 👋

[sand lotus]

oh pixel fun today

[ancient grotto]

Good morning

[unreal bay]

morning all 👋 Must be pi weekend, just been using a flatpak version of prusa slicer on the pi's this morning for first time, wont render opengl plater scene without LIBGL_ALWAYS_SOFTWARE=true flatpak run blah but shocked it worked at all (pi4+5)

[sand lotus]

i think he named it piomatter?

but i thought there was a protomatter already for the pi? what's the difference?

specific for the pi 5?

[unreal bay]

absolutely, my first time messing with flatpak recently, maybe had to use once before in ubuntu but had issues in past on pi's (years ago)

[sand lotus]

they renamed protomatter on microcontroller to RGBMatrix... i think?

my understanding of pio is that it has to be less than 32 instructions. seems like a small thing to run entire matrix panels with.

[nova totem]

You can also chain PIO programs together, I know some complicated stuff does that

[sand lotus]

OBS has a lighting setting for refresh rates that might help with that. might be related to adjusting for LED lighting but it might work for something like that too. maybe something to look into for another day.

we can just chalk all of the pio library to "Jepler Magic".... also not a bad name for a library.

[unreal bay]

if you drop the brightness of the panel / display to 15%-25% does it help?

[sand lotus]

not having enough power would show up as red lines. bright white lines is just timing glitches.

by default the chips in the matrix panels when sensing low power will turn off the Blue and Green part of the LED. so if you're ever trying to display white text and only see red that's a low power issue.

that is specific to matrix panels

cgrovers palletefader is great for helping with brightness issues. i used it on my 12 panel project and it worked great.

might help to explain that each matrix is split in half. the top half refreshes from bottom to top, and the bottom half of the matrix refreshes from top to bottom.

depending on how many panels you have the refresh effect is more visible in the directions each panel refreshes.

seeing video run on panels is always satisfying

[nova totem]

I still love using 2 panels to play GIFs on

[sand lotus]

it's really obvious with 12 panels on a microcontroller with lower refresh rates. it'll kill your eyes if you throw too much at displayio like 30 labels etc....

I think it's only for the entirety of the array.

Might not apply to the Pi, this is how it works for RGBMatrix library for microcontroller circuit python.

Since RGBMatrix was based on Pi Protomatter my guess is the basic premise is the same for both.

My point is, it doesn't matter how big the array is it's always split in half like this. Just the way the library is coded.

The more panels you have the farther the signal has to travel. Since data transmission length degrades over distance there is a limit to how many panels you can chain together.

Unless your panels are full white pixels on every panel you'll never use the full 4A per panel. Most projects are mostly black so well below the threshold.

I think it's the data required to keep Red, Green Blue full brightness and not power related. Lower the bit depth and you'll find it works much smoother too. It takes a lot more data to run a 6bit display than a 4bit display.

I could never get the font size below 7px with terminalio font. When I used a custom font designed for 5px that works much better.

I meant with displayio not repl. Yeah RGB888 isn't hard coded in RGBMatrix, you can change bit depth with the microcontroller version.

5x5 is the smallest you'd want to go for legibility. 3x5 is possible but only needed when you want to really squish some data onto the panel.

some fonts are monospaced, others are not.

So how did you connect the matrix panels together? Curious if you 3D printed the beefy mounts I designed. 🙂

Ah I don't think I have them for 3mm

Nice that'll work for 4 nicely. 12 has a lot more weight to it. https://www.printables.com/model/578204-hub75-5mm-pitch-4-panel-bracket

If you ever decide to add more you'll need beefier mounts for the weight.

[nova totem]

Ugh accidentally just put a Pico2 W build on my Pico 2 and zap goes my drive

I think the allocations are different because of the add on chip. Nothing important on there that I can't recreate. Unless past me was smart enough to save some of it (doubtful)

[sand lotus]

oh nice there's heretic and hexen in there too. Doom has had upgrades over the years but Hexen was almost as good and didn't get the same attention.

[nova totem]

Been a long time since I thought about Heretic and Hexen

[sand lotus]

As gory as the new Doom is I think they basically combined parts of Hexen into Doom with all the runes and stuff, so there's just 1 game now.

have a good weekend, hope you can figure it out and we can watch you playing some doom next weekend!

[nova totem]

can we all play Doom LAN style?

Fruit Jam RP2350B credit-card mini computer with all the fixin's 🍓🍇💾

We were catching up on a recent Hackaday hackchat with Eben Upton (https://hackaday.io/event/202122-raspberry-pi-hack-chat-with-eben-upton) and learned some fun facts: such as the DVI hack for the RP2040 was inspired by a device called the IchigoJam (https://www.hackster.io/news/ichigojam-combines-strawberry-and-raspberry-to-deliver-a-raspberry-pi-pico-powered-educational-micro-66aa5d2f6eec). We remember reading about this back when it was an LPC1114, now it uses an RP2040. Well, we're wrapping up the Metro RP2350 (https://www.adafruit.com/product/6003), and lately, we've been joking around that with DVI output and USB Host support via bit-banged PIO, you could sorta build a little stand-alone computer. Well, one pear-green-tea-fueled-afternoon later we tried our hand at designing a 'credit card sized' computer - that's 3.375" x 2.125", about the same size as a business card (https://hackaday.com/2024/05/07/the-2024-business-card-challenge-starts-now/) and turns out there's even a standard named for it: ISO/IEC 7810 ID-1 (https://www.iso.org/standard/70483.html).

Anyhow, with the extra pins of the QFN-80 RP2350B, we're able to jam a ridonkulous amount of hardware into this shape: RP2350B dual 150MHz Cortex M33 w/ PicoProbe debug port, 16 MB Flash + 8 MB PSRAM, USB type C for bootloading/USB client, Micro SD card with SPI or SDIO, DVI output on the HSTX port, I2S stereo headphone + mono speaker via the TLV320DAC3100 (https://www.digikey.com/en/products/detail/texas-instruments/tlv320dac3100irhbt/2353656), 2-port USB type A hub for both keyboard and mouse or game controllers, chunky on-off switch, Stemma QT I2C + Stemma classic JST 3-pin, EYESPI for TFT displays, 5x NeoPixels, 3x tactile switches, and a 16-pin socket header with 10 A/D GPIO + 5V/3V/GND power pins. The PSRAM will help when we want to do things like run emulations that we need to store in fast RAM access, and it will also let us use the main SRAM as the DVI video buffer.

When we get the PCBs back and assembled, what should we try running on this hardware? We're pretty sure it can run DOOM. Should that be first? 🙂 We also need a name. Right now, we're just calling it Fruit Jam since it's inspired by the IchigoJam project.

zephry way

[glad mortar]

ohno haha

[timid plover]

when you said "checked in" did you mean to your tannewt repo -r circuitpython ( like on circuitpython.org ?)

[glad mortar]

also excited for CPY on nRF5340

I used it a lot and been really missing something quicker to prototype with

L15 has no USB unfortunately, would that still qualify for CPY?

wait what, merge the SoftDevice port together with the Zephyr port?

wouldn't it make more sense to replace it fully?

oh cool right, that would prob. a good chip actually to introduce more people to that flow

[timid plover]

​​I see the commit on main now, thanks
https://github.com/adafruit/circuitpython/pull/10026

[glad mortar]

might cause trouble, or you would have to make your own SoC definitions so that the Zephyr device model is not aware of the hardware bits that you don't want managed by Zephyr

but I still think dynamic peripherals should work out if you are okay that CPY reboots on code change

yea deinit is really the only last bit, maybe CPY would give them the push to finally get that done

very few projects otherwise need it

[timid plover]

did @rapid hornet indicate he didn't want to loose resources (like USB connection ) on reboot - are there other non-reboot ways for CP to deal with changes?

[glad mortar]

not currently, that is what deinit support is needed for. There is now an active RFC so hopefully lands soon

[wind spoke]

Hello.
What is the importance of supporting new chipset?
What is it you cannot do with existing supported chipset, and you would be able to do?

[timid plover]

the discussion is CP on Zephyr, but is there a similar (maybe automatic) way to associate Zephyr to arduino (that some adafruit customers use )

[wind spoke]

If the Zephyr stuff does not change the API, will you change the CP Major Version number?

[timid plover]

you just answered that

[glad mortar]

This week I looked into the i.MX RT500 for a project, that might also be super interesting for CPY. It has 5MB internal SRAM and two really fast external memory interfaces for RAM and Flash

[wind spoke]

---

What additional benefits of using Zephyr?
Like better multi-core support?
Or time sensitive things more easy to do due to real-time?

[glad mortar]

Is the "Fruit Jam RP2350B" the CircuitPython Micro/Retro Computer we have been waiting for?
What (currently missing) features do you think are needed for making it real/complete?
Keyboard workflow is already supported... maybe a "build-in editor" or a "file manager"?

[timid plover]

there are several blogs and top secrets that mention Fruit Jam - looking forward to it!

[wind spoke]

Screen detection.

[gritty falcon]

Will it have an RM2?

[timid plover]

that was on show and tell the other day too
waiting for both that and the metro2350

Typically to run Linux a processor needs an MMU to support virtual memory.

[glad mortar]

not anymore, the MMU requirement has been dropped a few kernels ago

[gritty falcon]

Where can I find more info on the RP2 SMP support?

I'm feeling tempted. Must resist.

[timid plover]

there have been era's where the Function keys were very part of the PC environment

[gritty falcon]

That's very retro.

[timid plover]

yes - you and lady ada

The terminals in the office on "Severed" have a great feel.

[wind spoke]

Comodor 64, ZX Sprectrum, they all drop you on the "REPL"...

I think I have one or two #CircuitPython 202x on the topic... I might need to review those.

[lyric frost]

The retro machines use to drop you to basic, maybe drop to a modified REPL like your basicpython shell?

[timid plover]

how do you nudge copilot to do what you want?

[gritty falcon]

Sometimes I run co-pilot just to see how wrong it can be.

Me too. It really excels at generating tables.

Hi from Costa Rica.

Let me get my long-range wifi deauther :p

[timid plover]

why disconnect after success ?

does success mean it accepted the password - or just started communicating?

[glad mortar]

yea network manager is weirdly sparsely documented

but interace down can have many causes

for wifi it could mean disconnected from AP, for Ethernet that its unplugged

you would have to listen to the events of the interfaces itself

[timid plover]

phind suggests looking at
NET_IF_OPER_UNKNOWN - Initial unknown state
NET_IF_OPER_NOTPRESENT - Hardware is physically missing
NET_IF_OPER_DOWN - Interface is administratively down
NET_IF_OPER_LOWERLAYERDOWN - Underlying interface is down
NET_IF_OPER_TESTING - Interface is in training/testing mode

and also
NET_IF_OPER_DORMANT - Waiting for external action
NET_IF_OPER_UP - Interface is operational

[gusty wedge]

Can you check on the router if the MAC of the device has asked for IP?

[timid plover]

phind says it generated this picture to help

[gusty wedge]

It should not connect without a nonce.

[timid plover]

https://www.phind.com/search/cm6vetrqz0000356rc0nxmmdv

I like phind sometimes as it gives links

[steady osprey]

Totally unrelated to Zephyr, but...
I want to connect two of the 64x32 matrices together. I've been using Arudino to show stuff on one matrix, and it works great. On adafruit.com it says it should be possible to connect two matrices together, but the Adafruit library doesn't support it yet. Any ideas on where I can look to figure out how to make this work in Arduino?

[gusty wedge]

The nonce is similar to the salt in the shadow of linux.

You need some random text to cypher the key, so that it doesn't send the same text to the AP all the time. That would make it easier to crack.

Maybe the hardware entropy source needs a driver for the specific board enabled?

[nova totem]

I am 95% sure the Arduino library will support it now, let me see if I can quickly find it

https://github.com/adafruit/Adafruit_Protomatter/tree/master/examples/tiled

[glad mortar]

hci is different from the bluetooth controller

you can have a bluetooth host running on one part but radio on anothe f.e.

so radio etc. might not be turned on necessarily

depends on the thing you enabled

like you may have enabled the interface to a bluetooth controller but don't actually have a bluetooth controller on the other end

CONFIG_BT=y
should enable it tho

If the sensor requires less than 3.3V to operate normally?

[old surge]

👋

[cinder wind]

Using a GPIO pin to power a peripheral is a trick I use all the time, but be aware GPIO pins can only provide a few milliamps. For instance, the RP2040 (Pico) can only source 50mA total for all GPIO pins

This ultrasonic sensor draws only 3.5 mA so you're fine

PCM5102 and PCM5100 I2S DAC breakouts 🔊🎶

We're starting to stock a lot of chips that can do digital I2S out, which makes for great-quality audio playback. That's great when you have enough processing power to decode WAVs or MP3s in real-time. However, we could really use some better DACs in the shop. We like the UDA1334A (https://www.adafruit.com/product/3678), but that's technically discontinued - it's great because it doesn't require an MCLK that some boards like the Raspberry Pi don't have and doesn't need I2C configuration either.

The PCM510x is a good family, too; it ranges from the inexpensive PCM5100 (https://www.digikey.com/short/z50cnp0h) to the PCM5102 (https://www.digikey.com/short/80z2nh3h) which has high quality output at a higher cost. This breakout could use any of the family chips & gives you all the GPIO needed with a 3.5mm headphone jack for line-level output. We're testing it out with some cool tunes from the adafruit soundcloud, check it out! (https://soundcloud.com/adafruit).

Hey all, so whats cracking with the fruit jam talk, congrats on the undiscovered output resolution.
Is is possible to pick any res that is half the desired res (i.e. my laptop does 1366/1360 x 768)

[eager matrix]

When do you expect Fruit Jam to be shipping in production?

[nova totem]

Yeah not updating. Sorry my brain is melted after this week of work. English is hard now

[glad mortar]

the calling it "DVI" is afaik only done to not upset the HDMI Forum regarding trademark. Signaling wise its identical.

[glad mortar]

HDMI audio is not a requirement

signaling wise its compliant HDMI

HDMI audio goes over a different wire than the video

the only thing missing to call it HDMI in RP2350 case is certification to be allowed to use the trademark

[unreal bay]

"HDMI compatible"

like lego 😉

[nova totem]

Can it supposed RGB888 in displayIO or does the memory just become too much

[timid plover]

cool beep

[turbid hill]

yep

[glad mortar]

ah sorry I thought it was about eARC (which is its own wire to transport audio bidirectionally)

[dawn magnet]

beep yes

[timid plover]

the beep would get old :-), thanks for muting it

when you said USB - you meant the USB Host right - not the native USB ?

[nova totem]

If you have any C64 questions let me know. I still have the books that outlined every register they had and even circuit diagrams of the motherboard.

[unreal bay]

have you been looking at mass storage, or just general reliability with pio usb host?

[timid plover]

are there rp2040 vs rp2350 differences that could affect USB host or any other test code - I wonder if other test code hasn't been ported to rp2350 yet?

[unreal bay]

can we see the code

hehe, ye old timer, wait one cycle

[glad mortar]

nice 🙂

more USB host support def. exciting

[timid plover]

what about the PC dos character set ?

line drawing 🙂

you are right - higher level font support is better

[cunning cedar]

thinking of all the fun we had in the late '70s with 24x80 ascii terminals - blocky glyph plotting library I wrote, advent or zork text aventure games, many hours I spent playing rogue...

[timid plover]

does CP terminal support variable with fonts ? ( vs. fixed withd )

how must storage would unifont take?

maybe not all of it needs to be in RAM - some sort of cache?

when you say "terminal" are you refering to a section of CP firmware

[smoky island]

Is there any sample python code using terminalio? I've tried a few times and failed 😅

[cunning cedar]

the 5meg unifont....otf gzips down to 1.3meg. Does cp support unzip?

[unreal bay]

need that 16mb flash

[smoky island]

Thank you! I think I spot a few things I definitely did wrong based on that.

[cunning cedar]

hmm maybe one file per code-page (compressed in some easy way like rle)

[wind spoke]

Hi, I came to say "code page" and unicode equivalent.

[glad mortar]

I only half listened to the requirements (working on the side) but would it start to make sense to use a higher level framework for the terminal? My brain kept saying lvgl while listening 🙂

[timid plover]

did you see ixopac's youtube question about PSRAM and QSPI ?

missed it - ( audio issue - sorry )

[glad mortar]

mostly because they handle text and font handling already very extensively. It is very modular, maybe you could just use the text rendering portion and down the line move things around if you do endup using more of lvgl
