In reply to Saravann. lcd.h header file should be save in new text of same project. There will be two files in your project case Text1.c and lcd.h

Hi Sir,

Everytime I build and compile my program in keil, warning C206 always pops up and says:

LCD.C(37): warning C206: ‘Lcd8_init’: missing function-prototype

the Lcd8_init is properly declared and defined in your header file “lcd.h” and yet this warning is displayed. What might be the solution for this?

By the way sir, thanks for the examples. I learned a lot from you. The program is working properly both in simulation and hardware.

Thanks,

Cris
