AN2397 shows how to monitor CapSense data from PSoC 1 and CapSense controllers using the I2C or UART interface. With the tools described in this application note, you can view and log real-time sensor data for CapSense tuning and debugging.
Introduction
During the CapSense design process, you will need to monitor CapSense sensor data, such as raw count, baseline, and difference count, for tuning and debugging.
This document helps you to select the proper tool for viewing and logging CapSense sensor data. The two supported communication interfaces are I2C and UART. You should be familiar with CapSense sensing technology before you read this document. If you would like more information about general CapSense theory and operation, see Getting Started with CapSense.
- PSoC 1 and CapSense Controllers: Refer to the Selecting the Right Method section in this application note.
- PSoC 3 or PSoC 5LP: Refer to the “Tuner GUI” section in the PSoC 3 and PSoC 5LP CapSense Design Guide.
- PSoC 4: Refer to the “Manual Tuning Process” section in the PSoC 4 CapSense Design Guide.
