About this Code Example

The objective of this project is to demonstrate how to use the Capacitive Voltage Divider (CVD) feature of the ADCC module that can be found on many of Microchip’s newer 8-Bit PIC Microcontroller devices. This project will show how to get started with the ADCC module and make CVD measurements to detect a touch on a conductive sensor. The PIC16F19176 was used to emulate a simple eight key touch piano.
