LCD with PIC18F6490
PostPosted: Fri Mar 18, 2005 7:34 am     Reply with quote
Hello,

i'm trying to drive a LCD varitronix VIM828 with the PIC18LF6490. I'm using PCWH ver 3.214 with MPLAB v.7.01. I've use this code:
#include <18f6490.h>
#fuses HS,NOWDT,NOPROTECT
#use delay(clock=20000000)
byte CONST DIGIT_MAP[8] = {0x90,0xb7,0x19,0x36,0x45,0xff,0x00,0xaa};
#define DIGIT_1_CONFIG COM3+31,COM2+10,COM0+2,COM1+20,COM1+1,COM1+28,COM1+3,COM2+0


void main()
{
int i = 0;
setup_lcd(LCD_MUX14,1,ALL_LCD_PINS);

while (true)
{
for(i = 0; i<8; i++)
{
LCD_SYMBOL(0xff,DIGIT_1_CONFIG);
output_bit(PIN_C0,0);
output_bit(PIN_C1,1);
delay_ms(500);
output_bit(PIN_C0,1);
output_bit(PIN_C1,0);
delay_ms(500);
}
}
}

Someone know why I can't display nothing on the glass?
I connect bias resistor exactly like shown on page 263 of the data sheet.
I can't see any signal on the pin of the chip?
SOmeone can help me?

Thank you in advance

Roberto
