Tumbleweed, I had very strong suspicions that the issues were in the communication lines. I changed the Baud rate from 19200 to 9600 and I haven't got anymore wrong data at the receiver. I remember...
Ioannis, yes I'm doing data validation checks all the time. The first byte of the array is always 174. If this condition is not met, then the reading is discarded.
There is no much code to show here. I know device A is sending the right data because I can see it with a logical analyzer. I know device B, like 1 out of 5 times, is reading some bytes wrong because...
I tried removing the 10k resistor and I'm still having the same problem. The PICs are in two different PCB boards. The serial communication is taking place over a 3ft cable. The cable has 2.5mm mono...
Another thing that could be causing problems is that SEROUT2/SERIN2 are software bit-banged (no hdw UART involved),
so device B must be sitting waiting at the SERIN2 for the first start bit before...

Since this question has come up again, I thought I'd throw this module out to the masses. It is something I worked on a while back, with DT's help. Amid life's other priorities, it got put on the shelf to collect dust.
The basic idea is that by adding the module as an INCLUDE and inserting a couple of commands inside your code, you can have the PIC send timing data to your PC via the hardware serial port. It's made for 18F PICs (although some 16Fs may work too). You also need a timer that is not being used for anything else.
1) Instructions are included, as well as a small example.
2) It worked well for me, and as I recall, DT in testing.
3) Use it however you want.
4) I won't be able to offer much support, but figure there are enough knowledgeable folks around here that can help those who need it.
