Learning how to use USART

[richard]

The blinking LED on the transmitting PIC is working, and the LCD on the receiving PIC is working, but I'm not seeing any numbers being displayed.

given all things working display wise ,imho mike is leading you astray

tx unit:-

send = send + 1
hserout [send]

will send binary 0 to 9 , probably not the best idea but it is workable


ps weird baud rate


rx unit:-


hserin [dec data_in]
pause 5

will never work

1. its waiting for ascii numbers , the first non number will terminate routine
2. pause 5 why it serves no purpose and can cause framing errors


add this define
DEFINE HSER_CLROERR 1 ' Clear overrun error upon execution of every HSERIN command


rx unit:-
lcdout $fe, $94, dec data_in

if ok but it needs
hserin [data_in] to match data types

ps weird baud rate
