Serial data with flow control help
Archiver
Posts: 46,084
Happy Newyear!!
I have been trying to get serial comms with flow control to work
between two BS2E's.
I got the program from the manual to work, so then proceded to add
it to my own program, which didn't work.
so i went back to the manual example and tried to get it to work
again, and guess what, I couldn't get it to go!!
OK so in case I have blown something up, I have tested each stamps
I/O functions for the pins concerned. Each stamp can output a high
on each pin, and each stamp can detect a high on each pin. I then
tested the serial out to a LCD on each pin and it works just fine.
I simply can't work out what is going on. Can anyone suggest
anything else I should be looking at?
Regards,
Dwain.

After about 69 hours of frustration, I have finally found what was amiss.
I was using a forward slash instead of a backslash in the pin definition
part of the code, which rather than generating an error, simply stopped the
flow control. Now there's a catch for young players!!
Thanks again.
Dwain.

Don't you just hate it when that happens. Although, a lesson well learned.
You will likely never make that mistake again!
