Multiple serial devices to one pic

[HenrikOlsson]

Hi,
HSERIN2 is for the second (E)USART on PICs that have two - which the 16F886 doesn't so that's out.

SERIN or SERIN2 would work, just remember that they are both software timed commands and they are "locking" the rest of your program if you aren't using assembler interrups or DT-INTS. What it means is that if you you are using HSERIN to receive data from the GPS and SERIN(2) to recieve data from the odomter you'll be in trouble if both transmitts at the same time.

You seem to indicate though that the main PIC asks the odometer for milage data so you are in control of when it sends it. In that case I'd say that SERIN(2) would work just fine.

Thank You. I have not connected the odometer pic to the speedometer yet but I did add this and the speedometer still works. hserin 250, readgps, .........
Along with: define hser_rcsta 90h
define hser_txsta 20h
define hser_baud 2400
So as soon as I build the board for the odometer I should be able to remove the lcd commands and add a hserout connect the correct pins and life should be good. I know famous last words. We shall see today I hope.
