I wrote a program using UART on an Arduino Nano.
I then modified it to run on an ATTiny85 - I didn't delete the UART code - it was only referenced in a macro that was not used - and I had intended to go and modify this later - to get the data logged out without using USB comms (using a 'bare' 85)
Compiling gave lots of port D unknown error messages (true) - but clicking on 'Error results - bookmark all' crashes FC (closes after 10s or so).
