lcdpcf8574

Driver source code for HD44780 based LCD via I²C chip PCF8574 on Raspberry Pi. I have used PCF8574 I²C bus expander Chip for this purpose. This helps limited number of Raspberry Pi's pins to be better utilized. The best part is, those two pins also can be re-used because they are I²C pins, you can connect upto 127 additional devices.

Please take note that this code is based on the Python code posted by ufux at https://gist.github.com/ufux/6094977.

To build go to the source directory via a terminal.

$ make

$ sudo make install

That's it.

Enjoy!
