Hi all, just an info.

Serial_hw_write library seems to  add a quite large latency for the real
signals. For example the following instructions:
serial_hw_write (address)
serial_hw_write (dataH)
serial_hw_write (dataL)
;_usec_delay ( 100 )
compiled on a 32MHz clock microcontroller are adding a measurable latency
of about 80uS which seems a bit weird.
If those instructions are chained in a critical time loop, a delay after
those three compiler instructions is mandatory, without it, the
communication may freeze. Actually this delay includes the communication
latency. I've used a logic analyzer to understand that behavior.
best wishes,
