LC75824 LCD driver chip library for EFM8 microcontrollers

LC75824 is an LCD driver chip. It has 4 commons so it has 1/4 duty and supports 1/2 and 1/3 bias voltages. In addition to being able to directly drive up to 204 LCD segments, the LC75824E and LC75824W can also control up to 12 general-purpose output ports. Serial data input supports CCB format communication with the system controller.
The interface between the LCD driver and the microcontroller is done by using only 3 pins (CLK, CE and DATA).
I know this is an old and rare LCD driver but the library code can be used to adapt other LCD drivers. I use this because I have a broken Samsung MM-N7 audio system with a good display using this IC.
