I don't have one on me right now. But I'm looking for one. But from what I can tell, I don't think its transmitting at all and the reason for my suspicion is that both pins are set to INPUT
before the write. (i.e. at the time of the write to TASKS_STARTTX
register, both pins are in INPUT
mode)
Shouldn't they be set to OUTPUT
if we are going to set the state of a pin?
