-
- #| MCU Name
- #| You _MUST_ set this to match the board you are using
- #| type "make clean" after changing this, so all files will be rebuilt
- #|
- #| "at90usb162" # Teensy 1.0

- #| Compiler flag to set the C Standard level.

- #| Processor frequency.
- #| Normally the first thing your program should do is set the clock prescaler,
- #| so your program will run at the correct speed. You should also set this
- #| variable to same clock speed. The _delay_ms() macro uses this, and many
- #| examples use this variable to calculate timings. Do not add a "UL" here.
