static void toggle_led ( uint8_t  mask )

inlinestatic

Toggle LED.

Newer megaAVR devices can toggle a I/O pin by writing to PIN register, while on older ones this needs to be done by a read-modify-write operation. This function abstract these differences.

Parameters

mask	Mask of port LEDs to toggle
