Trying e32-900t20d lora interface with #reticulum on #rp2040 board. SDR catches the announce burst but on the other side it seems my FTDI adapter is dead. Cant receive or transmit even with raw serial ( I should with these modules)

I designed a PCB! I ordered some #RP2040 Zero (Waveshare clones) because I didn't feel like soldering a bunch of tiny SMD components when a tiny module with them already soldered could be had for under $3. Just needed to route everything out to connectors to make a functional ARGB hub, which could also act as an ARGB controller from the RP2040-Zero's USB port (though it is meant to be powered from the incoming ARGB connector).

ARGB splitters suck. They just duplicate the same signal to all outputs and ruin the addressable in ARGB. I'm attempting to use the #RP2040 PIO to create a smart ARGB splitter by counting the bits and outputting the signal to multiple pins. I attempted this years ago on an ATTiny, but it was too slow. PIO is fast enough to pass through the WS2812 signal unharmed as well as able to count the bits to know when to switch outputs.?

Dear lazyweb, I’m looking for an #RP2040-based board that has extra pins for the USB port, like Adafruit’s KB2040:
https://learn.adafruit.com/adafruit-kb2040/overview

This is for a professional project, so I’m a bit reluctant to use the Kee-Boar-Driver. 😅

Do you have any recommendation? How do you use such boards when you need an external (or industrial) USB port?

Boosts welcome for visibility. Thanks!

Adafruit KB2040

It’s a shiny KB2040! An Arduino Pro Micro-shaped board for Keebs with RP2040. With 20 GPIO available (18 on castellated pins, 2 on STEMMA QT port) you can easily make up to 100-keys matrices, or common 65% 5x15 layouts.

As a hobby thing I'm trying to code Conway's Game of Life for an Adafruit RP2040 + HDMI stick I got recently and it has me wondering what could be done with making the cells different shapes: hexagons, triangles, anything else that fits neatly in each other, what other cool shapes and behaviors can you get with similar conditions?

I wish my ADHD would actually let me work consistently on this, this has been a fun thought experiment of how to structure this

Well this week I did get the RGB ‘neopixel’ smart LED on the #RP2040 controller in my #MechanicalKeyboard to work, but in #QMK. Right now it tells me what OS it thinks it is connected to, and if caps lock etc are on. Layer changes later…

I did have to ask for help on Discord, but I have submitted another documentation PR.

@reiddragon @fuchsiii personally, I find the #ExaArcadia doesn't look like a system worth it's painful asking price compared even to a fully-decked - out #NeoGeoMVS 6-slot board + Games to match!

And I do kinda question the value given that they literally shove a #PiPico on their JVS Adapter Board.

  • I don't mean like a #RP2040 but like the box-standard board and that adapter PCB has up to 5 frames delay!
