PIC 18F4550 with LCD !
Posted: 23 May 2012 16:35
Hi
I am trying to get the LCD working with PIC18F4550 in EasyPIC6 board.
So I tried with this code :
// LCD module connections
sbit LCD_RS at RB4_bit;
sbit LCD_EN at RB5_bit;
sbit LCD_D4 at RB0_bit;
sbit LCD_D5 at RB1_bit;
sbit LCD_D6 at RB2_bit;
sbit LCD_D7 at RB3_bit;
sbit LCD_RS_Direction at TRISB4_bit;
sbit LCD_EN_Direction at TRISB5_bit;
sbit LCD_D4_Direction at TRISB0_bit;
sbit LCD_D5_Direction at TRISB1_bit;
sbit LCD_D6_Direction at TRISB2_bit;
sbit LCD_D7_Direction at TRISB3_bit;
// End LCD module connections
void main()
{
ADCON1 |= 0x0F;
CMCON |= 7;
Lcd_Init(&PORTB); // Initialize LCD connected to PORTD
Lcd_Cmd(Lcd_CLEAR); // Clear display
Lcd_Cmd(Lcd_CURSOR_OFF); // Turn cursor off
while(1)
{
delay_ms(1000);
Lcd_Out(1,1,text);
}
}
But the LCD dosen't show any message !
Can I find some HELP ? Please !
