The circuit is based on pic18f2455 with 2×16 lcd (hd44780) and it displays the date and time. There are source c and other header files prepared on mplab ide, there are also schematics and pcb files prepared with eagle. It is a good resource for people who do programming with c language.
PIC 18F2455 LCD clock This circuit for an LCD clock with a 16×2 dot matrix LCD display is implemented with a PIC18F2455 based alarm and calendar and just a few components. The display is connected to JP2. HD44780 is a compatible display.
LCD Clock Material list:
R1-R7 Pull-up resistors 10kOhm
C1, C2 22pF ceramic capacitors
