Clock with LCD and PIC 18F4620 v. 2.0

Press the button in the upper left to the latest version

Version 2.0 of this watch has been tested and has the following features:

1) Implement languages Italian, English and German runtime via the button PL3

2) Created printed circuit board (pcb)

3) Removed compensated oscillator from 10MHz and activated the 8MHz internal oscillator

4) Eliminated resistor of MCLR

5) Eliminate pull-up resistors on the buttons PL1 ~ PL5

6) When does NOT send more data synchronization via serial as it is under study the possibility of sending the EEPROM birthdays and holidays via RS232 so you can change or update without using the buttons.

Very soon, the mounting kit that includes the following components:

Printed circuit board (pcb), already programmed PIC 18F4620 (latest version), DS1306, DS32KHZ, LCD blue / white, Transistor, resistors and multi-turn trimmer, Capacitors, Sockets turned, buttons, LEDs, Buzzer, Lithium Battery, Male Strip and jumpers.

Thanks to the work of Daniele Bucciarelli was made the pcb below that is being tested and will not be long before the final version.

At first glance it might seem easy to find a suitable container, but ... this is not so.
