KiCad (kicad.org) is a FOSS application for designing circuits and printed circuit boards. It was used to create the circuit schematics for this project.
There are three KiCad circuit projects in this directory:
- LCD_Test_Generator, a 250Hz AC square wave generator for testing bare LCD displays using a PICLF19156 MCU
- LCD_Test_Generator_PIC12F1572, the same generator, but using a smaller, cheaper PIC12F1572 MCU
- LCD_Demo, a demonstration of driving an LCD from a PICLF19156 MCU
To open any of these KiCad circuit projects, open in KiCad the *.pro file in the respective directory.
