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,
