mruby、mruby/c（PicoRuby）のペリフェラルAPI共通規格のドキュメントを整備したい

やりたいこと

  • mruby、mruby/c（PicoRuby）のペリフェラルAPI共通規格のドキュメントを整備したい

ペリフェラルとは

  • マイコンの入出力に関する各種の規格
  • 今回の対象になりそうなのは、GPIO, ADC, I2C, API, UART, PWM

mruby、mruby/cの「共通規格」とは

  • 軽量Rubyフォーラム（mrubyのメンテ主体）、九州工業大およびITOC（mruby/cのメンテ主体）の共同の取り組み
  • マイコンでのRuby利用を促進するため、標準的なAPI規格を策定する（している）。そして公開したい（←これが重要）

Debug a Pi Pico app with Picoprobe（WSL2）

Run Powershell as an admin

  • usbipd list to find the Picoprobe's BUSID
  • If the BUSID is 2-2,
  • usbipd wsl attach --busid 2-2

On a terminal

  • openocd

On another terminal

  • gdb-pico [project].elf
