I am struggling to drive an LCD with a PIC18LF27K42.
The functions are all OK. They are working fine with a PIC18F14K50 with the same clock of 4MHz.
I suspect the error is in my configuration bits. I did review it without success.
Thanks for your help
I am using the following pin definitions:
define ENL LATCbits.LATC7 (OUT)
define RW LATCbits.LATC6 (OUT)
define RS LATCbits.LATC5 (OUT)
define DB7 LATAbits.LATA3 (OUT)
define DB6 LATAbits.LATA2 (OUT)
define DB5 LATAbits.LATA1 (out)
define DB4 LATAbits.LATA0 (out)
Before running the main() I am doing the following initialization:
PORTA = 0x00;
LATA = 0x00;
ANSELA = 0x00;
TRISA = 0xF0;
PORTB = 0x00;
LATB = 0x00;
ANSELB = 0x00;
TRISB = 0x1F;
PORTC = 0x00;
LATC = 0x00;
ANSELC = 0x00;
TRISC = 0x1F;
