Debugging the RP2350’s ARM + RISC-V cores was… an adventure
- GDB refusing to launch
- Too many breakpoints on RISC-V
- Switching architecture not as seamless as I thaught for debugging
You can read about it here: https://embeddedjourneys.com/blog/rpi-pico-debugging-multi-core-arm-risc-v/
Good to know as well that I only have 4 breakpoints available on my pico 2 with RISC-V, while I seem to have a lot more available when using the ARM architecture. #pico2 #RPIDebugProbe #debugging
This is how I take my Pico 2 on-the-go! 😅

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)

The Pico 2 W now sends MQTT messages to Home Assistant, via the Mosquitto broker add-on.
The sensor is read by adding the following snippet to HA configuration.yaml:
...
mqtt:
sensor:
- name: "Temperature"
state_topic: "weather/inside"
suggested_display_precision: 1
unit_of_measurement: "°C"
value_template: "{{ value_json.temperature }}"
- name: "Humidity"
state_topic: "weather/inside"
unit_of_measurement: "%"
value_template: "{{ value_json.humidity }}"
- name: "Pressure"
state_topic: "weather/inside"
unit_of_measurement: "hPa"
value_template: "{{ value_json.pressure }}"
...
I also added the InfluxDB add-on, for possible longer data retention.

Right now, I only have a BME280 sensor and a Pico 2 W, solar power will have to wait. Sensor readings look good!
Raspberry Pi Pico 2 W with MicroPython on OpenSUSE Leap 16.0.
The terminal emulator minicom is not available on Leap, but picocom is:
$ sudo zypper install picocom
$ sudo usermod -aG dialout $USER
Log out, and back in.
$ picocom --quiet --baud 115200 /dev/ttyACM0
Type Ctrl-a Ctrl-x to exit.
Thonny IDE can be installed as a flatpak from flathub.
The minicom terminal emulator can be used from a Tumbleweed distrobox, but then you need to setup udev rules, see link.
The #MZ700 emulation for the #Pico MZ is nearly finished! Documentation to write and update, plus testing on #RC2014 cards and #Pico2 hardware left to do. Hoping to have version 3.0.0 released by the end of the month. #RetroComputing

Very nice new gadget, the #PicoCalc by #ClockworkPi! 🤩 Got mine a few days ago and am currently learning a lot about how it works. Documentation is a bit sparse, currently. You have to study many forum posts on forum.clockworkpi.com, there's currently no "gettings started" guide. – A bit disappointing: No Python (neither Micro-, nor Circuit-) out of the box. But folks (not ClockworkPi) are working on it. – If you're into Forth: it's already there. #RaspberryPi #Pico #Pico2 #MMBasic
Мурмулируем Mac 128K
Есть у меня хобби: портирование всякого-разного под Мурмулятор , и попалась мне на глаза реализация одного из самых древних "маков" - Macintosh 128K: https://github.com/evansm7/pico-mac . - Это же почти готовая прошивка под Мурмулятор, - подумал я. Основное отличие - другая распиновка VGA, да и реализация периферии немного отличается. После того, как в профильном чате ТГ канала этот эмулятор тоже упомянули пару раз, как кандидата на портирование, взялся за него и я.
