Code:
DEFINE HSER_RCSTA 90h
DEFINE HSER_TXSTA 20h
DEFINE HSER_BRGH 0   <-- Don't exist
DEFINE HSER_SPBRG 64
DEFINE HSER_CLOERR 1  <-- HSER_CLROERR
@12MHZ what is the expected baudrate? 2400?
using the calc i done few month ago
@12 MHZ you must use the following
Code:
DEFINE HSER_RCSTA 90h
DEFINE HSER_TXSTA 20h
DEFINE HSER_SPBRG 77 ' 2400 Bauds
DEFINE HSER_CLROERR 1
about now?
