PicoCalc Calc Firmware

This has been tested only with a Pico 2W.

Build, flash, and type "help".

Notes

Requires keyboard firmware update for battery display.

Issues

• Scrolling for history is still broken and doesn't work
• "long" inputs with errors doesn't line up properly somehow
• Directional key left/right goes two chars instead of one ???

Features

• Maths! It does uses the TinyExpr library, it isn't super fresh but it does work.

Current commands

flash: reset in flash mode
reset: soft reset
bat: get battery level
mem: show memory usage (broken)
ver: show version
uwu: ???
anything else will be fed to tinyexpr (he's hungry)

TODO

• Fix the history scroll issue
• Implement up/down for the history maybe
• Idk maybe commands history ?
• RTC with a hardware mod https://forum.clockworkpi.com/t/rtc-inside-the-case/16484/2
  • Implement time set time etc. (Could uses GP0/GP1 to avoid overlapping on the PSRAM pins, plus GP28 for the interrupt pin)
• Enable PSRAM ?
