That's fine. I was just curious if there was some other debug level, that
might note connect/disconnect of the port, or other useful things that were
less constant, also might exist. I've removed it totally for now.

Fifthly - Look into using the two PRU's to help offload some tasks. Also
look into using using specific external hardware to offload even more from
the CPU.
Could also be that your routines need some tightening up. Have you done any
cycle counting on your code ? Checked the generated ASM ?
