I own several PI 1011_0's. (2/2/2)
I have used them exclusively as digital input and receiving callbacks on state changes.
However I now need to send "serial" data (ie: morse code cw) output to a digital output pin.
Is there an API method that I can provide a series of bits to be sent out at a timed rate?
Or am i 100% responsible for the timing of digital output?
