• [x] Test firmware compilation, many boards/architectures
• [x] Test example compilation, many boards/architectures

Try LED and accelstepper:

• [ ] run on uno,mega
• [x] run on m0/m4

Finish

• [x] When done, add to library.properties, architectures
• [ ] get review & submit pr

Pin digital read/write, pin analog read, accelstepper

Tested:

Controller -> Target

Itsybitsy M0 -> Itsbitsy M4
Itsybitsy M4 -> Itsbitsy M0
Metro M0 -> Itsbitsy M4
Feather M4 -> Itsbitsy M4

Fails (also fails in pre-merge main branch):

• Uno -> Mega2560 (no i2c communication works)
• Mega2560 -> Uno (no i2c communication works)
