Project: CapSense Proximity and UART

5.3.1

Project Overview

The project

CY8CKIT_040_Proximity_UART.cyprj

implements a capacitive proximity sensor con-

trolling the brightness of a LED. The project configures the sensor as a CapSense proximity widget
with SmartSense Auto-tuning.

Firmware Details on page 61

presents the firmware flow and explains

the firmware blocks in detail.
