How to Create a Low-Power Sensor

Open Touch Configurator

Select MCC and open Touch Configurator in the Resource Management (MCC) tab.

Create a Low-Power Sensor

Once the Touch Configurator is opened, in the Create tab, add the required number of buttons/sliders/wheels. Select the required sensor and click Configure as Low Power.

Event System Driven Low-Power

To create Event System Driven Low Power, once the sensor is configured as low-power, open Touch Configurator > Configure > Low Power > Configure event system (this option will be checked by default).

The following animation shows how to configure an event system-based low-power sensor.

Configure Low-Power Without Event System

To create a Low Power sensor without event system, open Touch Configurator > Configure > Low Power and uncheck Configure event system. To configure Low Power parameters, select Configure > Low Power. The following parameters can be configured according to user requirements: Low power Measurement Period, Touch inactivity timeout, and Low power Drift Wakeup.

You can see the parameter details by hovering the mouse over the parameter value drop-downs in the configurator.

The following animation shows how to configure a Low Power sensor without event system.

Configure Lump as Low Power

Initially, the required sensors are selected, and Lump is configured. A detailed description for creating a lump sensor is provided in the "How to Create a Lump Sensor" page. Select the Lump Sensor and click Configure as Low Power.

Once the lump sensor is configured as a low-power sensor, it can be set up either as Event system enabled or disabled, as given in Steps 3 and 4.

Important Notes: Update the specified hints in the Project Files and the Devices Resources tab.

From Device Resources > System, add SLPCTRL, which is added in the Project Graph/Builder.

Generate Low-Power Sensor Code
​​​​

Click Generate in the Resource Management (MCC) tab.

Add touch_process() and call the sleep instruction in the main > while() loop as shown.
