I am a beginner to C language... I have alreaady initialized the LCD in my code...How do i display a message("HELLO" eg.) to LCD? I want to use it in function void but i do not know where to start...I want to make it simple if possible...There are samples that i found but the samples are complicated...
Your definition of lcdwrite has:
void lcdwrite(char *letter)
but your call to it is
lcdwrite('c');
Spot the mismatch?
