How hard would it be to add a nanoseconds delay to delay.h?
It would probably have to be a busy wait with compensation for the current CPU frequency.
I'm not sure what you mean, Peter?
Busy wait is a loop of some number of NOP instructions, as opposed to relying on some CPU peripheral such as a timer to signal elapsed time. The number of NOP instructions has to be calculated from the current CPU frequency.
