Multiple SERIN's

[crocodilebobbie]

Hi:

I found this same problem when the serin command does not get
what it is looking for. If the strings do not get to the SERIN in the right
format, then the serin just hangs up the PIC. The PIC is waiting for the
correct number format.

for example.

SERIN PortC.0, t300, [170,170,TempIn]

if the numbers 170 are not transmitted, or arrive correctly, the PIC hangs
waiting for the correct "strings"

Why don't you connect all the Serial pins up to the same pin?

Use Serin with the "Flag" or "Qualifier" to acknowledge good data.

You can have bi-directional via one pin...a slave and/or master.

When you use Serin on 3 different pins...You can still use the Qualifier, but I would use a very short "timeout". And either way, there is no guarantee you will lose a packet or two sometime or another. You may have to keep sending until you receive your data from the chip, them send a "receive" bit.
