AN42137 - Capsense™ Express Software Tool
The CapSense Express Controller enables the control of a maximum of 10 IOs configurable as either capacitive sensing elements (used as buttons or combined to form a slider), or GPIOs, driving LEDs or interrupt signals, based on various IO conditions. The GPIOs are also configurable with interrupt for waking up the device from sleep. The user can configure buttons, outputs, and parameters, through specific commands sent to the I2C port. The IOs pin mapping flexibility (capacitive elements and GPIO functions) enables easy PCB trace routing and reduces the PCB size and stack up. CapSense Express products are designed for easy integration into complex products.
