group assignment:

• demonstrate and compare the toolchains and development workflows for available embedded architectures

press boot button while you plug it in

Arduino

1. press boot + plug in
2. board shows up as unknown UF2 board
3. reset through button, then select the right port after it pops up
4. make sure you have the right board selected
5. press the arrow to flash the program onto the board
6. yay!
7. note: need to install libraries in Library Manager if needed

MicroPython

• Flashing MicroPython onto RP2040
  • plug board in while holding BOOT
  • RPI-RP2 folder/drive shows up
  • after downloading the .uf2 file on micropython.org (this is the MicroPython firmware), drag it onto the RPI-RP2 drive to upload it
  • XIAO RP2040 MicroPython download
  • board kept ejecting itself/rebooting automatically — this is correct and means that MicroPython installed
• VSCode - MicroPico
  • 
  • have to use RP Pico instead (no RP2040)
  • install the MicroPico extension to write code
  • open VSCode with a new project (main.py)
  • install the MicroPico (by Paul Ober) extension for MicroPython
  • you can do PlatformIO, but that runs Arduino
  • this extension lets you use Cmd+Shift+P for the MicroPico command palette
  • in the MicroPico command palette, initialize project
  • in the MicroPico command palette, upload ws2812.py project to board
  • in the MicroPico command palette, run current file on board while on blink-echo.py
• Thonny
  • Seeed Studio XIAO RP2040 with MicroPython
  • don't need to enter boot when plugging in because we assume .uf2 is already flashed
  • save ws2812.py to Raspberry Pi Pico (File → Save As)
  • 
  • ran the hello_led_counter.py example
  • it counts!

Rust

1. download Rust - curl command
2. download extension for Rust on VSCode
