MicroCode planning

[tballmsft]

MicroCode is currently a prototype. To take it to the next level, we have a number of workstreams.

Infrastructure (no user visible change)

• move off of jacdac-c, onto pxt-jacdac
• replace compiler with interpreter
• minimal program syntax with compiler (convert samples to using syntax)
• redo binary representation for extensibility
• create API for adding new tile
• unify representation of on-board and Jacdac peripherals?

Programming model

• comparison operators

User interface

• put in default tiles for sensor
• better UI when a Jacdac module is added to bus

Smart shield with RP2040

• MicroCode UI runs on RP2040
• Interpreter only on V2
• send program over Jacdac from RP2040 to V2
• interpreter events back to RP2040
• MakeCode Arcade support for full 320x240 on RP2040?
