tsi_v5_mutual_cap

Overview

The tsi_v5_mutual_cap example shows how to use TSI_V5 driver in mutual-cap mode:

In this example , we make use of the available electrodes on board to show driver usage.

  1. Firstly, we get the non-touch calibration results as baseline electrode counter;

  2. Then, we start the Software-Trigger scan using polling method and interrupt method;

  3. Then, we start the Hardware-Trigger scan using interrupt method.

Running the demo

When running successfully, the log output in terminal shall be similar as below:

TSI_V5 Mutual-Cap mode Example Start!

Please do not touch pad KEY3 when in calibration process! Calibrated counters for mutual-cap pad KEY3 is: 2198

NOW, comes to the software trigger scan using polling method! Mutual-cap pad KEY3 Normal mode counter is: 2200

NOW, comes to the software trigger scan using interrupt method! Mutual-cap pad KEY3 Normal mode counter is: 2198

NOW, comes to the hardware trigger scan method! After running, touch pad KEY3 each time, you will see LED toggles.
