tsi_v4_low_power_mode
Overview
The tsi_v4_low_power example shows how to use TSI_V4 driver in low power modes:
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 Hardware-Trigger scan using interrupt method to wakeup from low power modes through pad touch;
Note: you can select which low power mode you want to enter into.
Running the demo
When running successfully, the log output in terminal shall be similar as below:

Let’s move to the low power modes world!!!
Press specific key to enter stop mode. After enter stop modes, touch PAD XX to wakeup.
Please input the mode you want to enter! 0 ——> STOP MODE 1 ——> VLPS MODE 2 ——> LLS MODE 3 ——> VLLS1 MODE 4 ——> VLLS2 MODE 5 ——> VLLS3 MODE About to enter into STOP MODE! Great!!! You touched it!!!
Please input the mode you want to enter! 0 ——> STOP MODE 1 ——> VLPS MODE 2 ——> LLS MODE 3 ——> VLLS1 MODE 4 ——> VLLS2 MODE 5 ——> VLLS3 MODE About to enter into VLPS MODE! Great!!! You touched it!!!
Please input the mode you want to enter! 0 ——> STOP MODE 1 ——> VLPS MODE 2 ——> LLS MODE 3 ——> VLLS1 MODE 4 ——> VLLS2 MODE 5 ——> VLLS3 MODE About to enter into LLS MODE! Wakeup will lead to a interrupt flow, pay attention to it!!! Great!!! You touched it!!!
