while I'm using PORTC for LCD input, every thing is fine. but LCD is blank while I'm using PORTB. why !?
Code:
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;
void main() {
TRISB = 0;
Lcd_Init(); // LCD display initialization
Lcd_Cmd(_LCD_CURSOR_OFF); // LCD command (cursor off)
Lcd_Cmd(_LCD_CLEAR); // LCD command (clear LCD)
LCD_OUT(1 ,1 ,"HELLO");
LCD_OUT(2 ,2 ,"222222222222");
LCD_OUT(3 ,3 ,"333333333333");
LCD_OUT(4 ,3 ,"444444444444");
}
