/*For some reason in our board, which I've been explained but I'm not capable of explaining it again, including LED1 and LED4 being part of usb serial,
|
||
|
|
we can't use plain pinMode and digitalWrite on those pins (at least the output ones, for what I've tried so far), so we gotta use registers and modify them manually
|
||
|
|
While this is a bit of a PITA, runs faster on the the uC
|
||
|
|
Also using Arduino Micro bootloader, seems to work fine
|
||
|
|
If Arduino Micro bl doesn't appear to work right, try the Sparkfun ProMicro ones
