Interface PIC12F615 with LCD display

[Okba_]

This is a simple project shows an interfacing of the microcontroller PIC12F615 with Lcd display. This interfacing uses only two lines one for data and the other for clock. A shift register is used here to receive data from the microcontroller and then send it to the Lcd display. A MikroC library called Serial Lcd display must be installed.
The shift register can be 74HC164, 74HC595, CD4094 or any serial in parallel out shift register.

You don't need to tie the unused data lines on the LCD low, it is best to leave them unconnected as the LCD has quite strong pull up resistors on them.
