Software TODOs[edit]
Display drivers[edit]
Choose bit depth(s)
It seems the display supports a low power 8 color mode, with no backlight that might just be enough for low power watch app . .
Choose UI kit
Input[edit]
Since we only have UP, DOWN and CENTER we'll at-least need something like long press for Cancel / Back . .
Multimeter[edit]
This is the easiest of the following . .
Oscilloscope[edit]
High speed magic needed
Component tester[edit]
There seem to be a couple of "flavours" of this, some with very nicely commented code
