#RP2040

2025-12-30

So, a while ago I assembled a #piantor, hotswap sockets and Pi pico usb-c clone, and yesterday I got around to testing it. Everything worked fine, except for one single key on the left half. After probing around using a multimeter, and using the digital microscope I bought on a whim, I found what looks like a cold joint on the pin on the #RP2040 the key is connected to.
I don't have a hot air station nor a reflow oven nor a tip fine enough to fix it, so I'll need to replace the Pi I think 😢

Anyone know the deal with the #ESPHome `rp2040_pwm` output component? It exists, but it's undocumented and I can't find any reference to in on the ESPHome website 🤔

Wrapped up my latest custom today. It’s a single handed keeb designed exclusively for playing . Designed in TinkerCad and on my mk4. Then hand painted with Panduro Hobby Acrylics and dusted with weathering powders. Running on a Xiao .

Front of the keyboard. It’s a metallic colour made to look weathered and rusty. It contains for rows, six columns and a small thumb cluster.Inside of the keyboard. Uses flexible copper rods hand wired to the switches and to a very small microcontroller

My 36-key #RP2040-powered custom #MechanicalKeyboard is almost ready! I now need to flash it, but I can't say I'm impressed by any of the popular firmware projects. 😒 My gripe spans from GitHub being used as a synonym for version control system, pipe-to-Bash of random scripts, toolchains hard to reproduce, etc.

From the #DECtalk Mini github repository I commpiled with the #Pico-SDK today the RPi #RP2040 Pico version and changed it
from USB serial 115.200 Baud
to GPIO0/1-TTL-Serial 9600Baud.
Sounds fine on the left 3.5mm Audio channel
(GPIO28/Pin 24) of a
#Olimex RP2040-Pico-PC Board :)

Made some progress on prototyping a #RP2040 based #USB Audio interface. I got a PIO program to output a good looking TDM signal for 4 channels of 32-bit samples.

Now I can start prototyping the receiving end of the transaction, DMAing samples into RAM and packing them into isochronous USB packets.

I am slowly getting better at soldering, 4 out of 7 successful #MechanicalKeyboard PCBs now - all three of my diode-free #GraphTheory wired keyboard PCB designs have worked (eventually) ⌨️🎊

Have you ever been Doing a Thing on a different hardware platform and said to yourself, "Self, this would be so much easier on an RP2XY0 using DMA and the PIO blocks!" (Even though for other reasons you can't switch hardware)

@easytarget the article mentions #RP2040 and #ESP32. Does anyone know how #Enshittification proof their organizational structures are?
