Happy scenes in the #doghouse working on the next #CNC machine project. Having to use windows which feels weird, but whatever the OS its good to get this BTT SKR #Pico board moving motors correctly. #rpipico #grbl #grblHAL

Question for electronics folks: if I make a cheat sheet for the pinouts or popular dev boards, do you prefer separate figures for the Raspberr Pi Pico, Pico W, Pico 2, and Pico 2 W, or one generic one is enough, knowing that the pins are the same on all of them?

Yesterday, I was battling kernel issues, and thought I had solved them… but 'lo and behold, they're back.

The device is a Raspberry Pi Pico RP2040 and the firmware is based on https://codeberg.org/sjlongland/modbus-ina219-bridge -- it works fine on other machines, just not the Ubuntu laptop at work.

The `usbtouchscreen` messages are a clue… it seems it's interacting and fouling up `cdc-acm`, if I remove it and re-plug, I get this:

```

```

So looks like I need to blacklist `usbtouchscreen`. No idea why this is even being loaded, there are 0 touchscreens on this machine, USB or otherwise.

#Zephyr #Ubuntu #RPIPico #RP2040

Took all of 5 minutes to “clean up” my #SBC set-up. I have downsized the SBC that I currently use. Now I am down to the following:

1) @PINE64 Rockpro64 which is my mini #Debian file server (black box with stickers)

2) #MangoPi Pro a D1 #riscv sbc for tinkering (small black box)

3) #RPipico emulating a 128K Macintosh (grey box)

4) #OrangePiRV2 (clear box) an 8core K1 riscv sbc also for tinkering.

All my other sbc are collecting dust in a box until I find a use or they end up in the e-recycling bin.

Not content with this success, I went on to write a pico C++ driver for the lsm6ds3 accelerometer using the pimoroni-i2c library as there did not appear to be any C++ drivers in the wild for this on #rpipico
This along with the touch screen C++ driver I converted from lvgl to the pimoroni-pico graphics will be published in my #presto examples once I have fully implemented the driver and written some simple boilerplate examples.

The PicoCalc uLisp Machine is a Clockwork Pi PicoCalc handheld computer that runs uLisp, a Lisp implementation for microcontrollers.

The Clockwork Pi PicoCalc features an RP2040/2350-based Raspberry Pi Pico or Pi Pico 2 board, and has a nice 320x320 4" colour IPS display and keyboard. uLisp provides a rich environment and tools.

The moment when the chinese clone is better than original, waveshare RP2040-Zero, it might have less GPIO, but USB-C port is the winner. I have no ideas what was RPI foundation thinking about using micro-usb port in theirs RPI Pico #rpipico #waveshare this will be brain of my next #handwired #keyboard

the Raspberry Pi Pico 2 W is available now.
just rare on stock.

Also, never ever send keycode for Enter on no event. Hihihi. Took me while to figure casting sleep on cp code revision.

Oh, RPI Pico 2! #rpipico

Unbrick Raspberry pi pico micropython - Restaurar firmware cuando falla código en main

A veces en nuestro código se provoca una excepción o realizamos alguna acción que rompe la ejecución demasiado pronto para que nos de tiempo a parar e insertar una corrección.

Os dejo una solución para reflashear por completo y dejar la pico como recién llegada para continuar el desarrollo.

Got an ISO mounted in NEXTSTEP on the NeXTstation with my new BlueSCSI v2 device. Awesome addition to the system.

Right angle vs vertical connectors! Which is more popular?

KF141 quick connectors: the right angle version is ahead by 3:1 after a week.

Pico silkscreen headers: right angle was a last minute decision. First instincts were right: vertical is ahead by a whopping 10:1..

#buspirate #openhardware #rpipico

RPi Pico is great, but the tiny misaligned pin labels are not. We asked Uncle to silkscreen the Pico pinout on 20p headers when we sent KF141s. We picked the best header out of 10 manufacturers and used a two-part silkscreen process that's extra sharp.

Warum einfach, wenn's auch kompliziert geht?

Maker community should be excited with this one. No audio support over Bluetooth as per the reporting though (actually had a project in mind for that, ah well, welcome all the same)

Modules arrived today. Various resolutions and bit depths. Plan to make the graphics lib code device agnostic. #rpipico #spi #tft

Needed a cross section of display modules to test my RPI PICO GFX LIB against. Cant make it hardware agnostic without some kit. Ordered a variety of interface tech (i2c, spi) bit depth (1bit to 65k) and sizes including a huge 2 inch display!

Hey @yezzer -- don't forget to try #MicroBlocks to program the #RPiPico. Lots of easy-to-load libraries supporting sensors, actuators, sophisticated add-on hw, and some fun kits, such as PicoBricks. Unlike other blocks languages, MicroBlocks is LIVE. Blocks in the IDE are kept in sync with blocks on the board. Click any block(s) to immediately activate! ⚡
