Picocalc

This is a handheld device made by Clockwork (the same company that makes the uConsole). I helped port uLisp to it. There's still some work to be done, all dependent on replacing the screen.

• [X] Replace the screen. It's in the mail, I guess it shows up when it shows up. Update: it's installed, and I used electrical tape to secure it in place.
• [X] I had no success finding devices on the i2c ports. I'd like to get i2c working, then add support for an RTC. Update: it appears to be working; at least, it shows the keyboard (0x1f). Update 2: the RTC works, using expansion port pins \(GP_4\) and \(GP_5\).
• [ ] Most of the function buttons don't do anything. Again, I should find a way to make these useful. For example, maybe an ability to bind keys to the F\(n\) buttons.
• [ ] Work out a mechanism for communicating with "backpacks," which are currently being prototyped as Game Boy-style cartridges. Right now, the ones I would like to see implemented are:
  • LoRa radio
  • Teensy coprocessor for additional compute (even better if it could be async)
  • Sensor package, such as PHT, air quality, radiation, etc.
  • IMU package for grins.
• [ ] Might be able to port the new editor and doc-browser.

I've ordered two:

1. Order #33774, placed on [2025-03-13 Thu], shipped on [2025-03-27 Thu], arrived on [2025-03-31 Mon].
2. Order #35912, placed on [2025-04-10 Thu]. I'm debating running the PicoMite BASIC firmware, but it could be interesting to build a Collapse Computing UI in ncurses with support for Meshtastic.
