6.8 Summary

This chapter has briefly described the operating principles of LCD displays when used in microcontroller based circuits.

The creation of user defined characters has been described with an example.

The LCD instructions and the LCD initialisation sequence have been given for both 4-bit and 8-bit interfaces. A C program is given to show how the LCD can be initialised from the first principles and how it can be used in a program.

mikroC Pro for PIC language provides a library of LCD functions that can be extremely useful while developing LCD based microcontroller projects. A list of the available functions is given, with examples to show how they can be called from C programs.
