I have 2 PIC16F876 processors and I am trying to comunnicate serially between them. I need to send 3 nimbers. I have tried numerous configurations, but can not get a reliable transfeer. I get a variety ov numbers but not the values that I asigned to the variables I am using an LCD display as a test device simply to view the results. Whats wrong?
Display program
AX VAR BYTE
BX VAR BYTE
CX VAR BYTE
DEFINE LCD_DREG PORTB
DEFINE LCD_DBIT 4
DEFINE LCD_RSREG PORTB
DEFINE LCD_RSBIT 1
DEFINE LCD_EREG PORTB
DEFINE LCD_EBIT 3
DEFINE LCD_BITS 4
DEFINE LCD_LINES 2
DEFINE LCD_RWREG PORTB
DEFINE LCD_RWBIT 2

SERIN PORTC.3,0,3500,LOOP1,["A"],#AX,#BX,#CX
LCDOUT $FE,$C0,#AX
LCDOUT $FE,$C0 + 4,#BX
LCDOUT $FE,$C0 + 8,#CX
PAUSE 3000
GOTO LOOP1
;Program for outputing the data

AX = 2
BX = 150
CX = 1
