I have problem with atmega32 and char lcd 2x16 project
so , I need help
the problem :
when I add more code for my code that make the micro not work !
let's see
the code work well
Code: Select all
// LCD module connectionr
sbit LCD_RS at PORTD4_bit;
sbit LCD_EN at PORTD3_bit;
sbit LCD_D4 at PORTC2_bit;
sbit LCD_D5 at PORTC3_bit;
sbit LCD_D6 at PORTC4_bit;
sbit LCD_D7 at PORTC5_bit;
sbit LCD_RS_Direction at DDD4_bit;
sbit LCD_EN_Direction at DDD3_bit;
sbit LCD_D4_Direction at DDC2_bit;
sbit LCD_D5_Direction at DDC3_bit;
sbit LCD_D6_Direction at DDC4_bit;
sbit LCD_D7_Direction at DDC5_bit;
// End LCD module connections

what can I do ?? , what is the problem ???
notes
1. I use MikroC pro for AVR 3.5
2. programmer is USB-ASP
3. crystal 16M
