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.
Firstly, we get the non-touch calibration results as baseline electrode counter;
Then, we start the Software-Trigger scan using polling method and interrupt method;
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.
