i dont know how to solve it .and i'm would you please help me.. thank you!:
Have you written the LCD code... If you copied your code off the net, look for the LCD.c file and LCD.h file that goes with it.... There are generic LCD routines in Keil but I don't know where they are located.... They will be in a source (src) or samples directory where Keil was installed
just find and copy the content of lcd.h into your .c file and compile. then it will not give any error. plus keep in mind that if your keil is a free version, it will not link your .c file to hex file if size is greater that nearly 4kb...
