Well, I'm attempting to use an LCD-module with ATmega16 -controller. I met a confusing problem. I'm programming with CodeVisionAVR, which has a library of lcd functions.
When I wrote into main program:
lcd_gotoxy(0,0); lcd_putsf("hello world");
That resulted perfectly correct displaying of text "hello world" on the LCD, so the lcd and its connections seem to be ok.
BUT when I attempted to use lcd_putchar -function, which should display the value of a variable, a problem occured. So firstly, I declared a global variable h and set it to 1, by writing at the beginning of the code:
int h=1;
Then attempted to get it displayed by writing into the main program:
lcd_gotoxy(0,0); lcd_putchar(h);
But the "1" didn't get displayed. Instead, it displays || -looking character. As well did many other values of h, and some values displayed as |||
-character.
I also tried changing the data type of the h from int to char and unsigned char, but with same results. What might be wrong?
