5.1 My First Code Example
5.1.1 Project Objective
This example demonstrates how to operate the CapSense buttons and sliders. When you configure
CapSense buttons and sliders in the CSD wizard, the corresponding LEDs check the functionality of
CapSense buttons provided on the board.
The following user modules are used in the project:
■ CSD: The CSD (Capacitive sensing using a Sigma-Delta Modulator) provides CapSense func-
tionality using the switched capacitor technique with a sigma-delta modulator to convert the sens-
ing switched capacitor current to digital code.
■ LCD: The LCD module is used to display a horizontal bar graph when the CapSense slider is
touched.
■ LED (1–2): LEDs 1–2 glows when CapSense buttons are touched.
