Hello CCS friends,
I try to display " Hello world " on LCD display, but LCD don't display any character, even cursor also. I use inbuilt lcd.c library. My lcd model is JHD162A. I connect LCD in port B.
My code is
| Code: |
#include<16f873a.h>
#device adc=8
#use delay(clock=4000000)
#fuses NOWDT,XT, PUT, PROTECT, NODEBUG, BROWNOUT, NOLVP, CPD, NOWRT
#include <lcd.c>
#include <string.h>
///////////////////////////////void main function///////////////////////////////
void main()
{
lcd_init(); // init the LCD
delay_ms(100);
output_high(pin_a0);
lcd_putc("\fHello World\n");
while(true)
{
output_high(pin_a0);
delay_ms(200);
output_low(pin_a0);
delay_ms(200);
}// while
}
|
Please see my code and give the best solution. |

The CCS LCD.c file defaults to all connections to port D. If U wish to use PORTB then the line #define use_portb_lcd TRUE must be added in your program before the LCD.c file is included. Try it now  !! |
