Overview
The CapSense Express™ controller allows the control of 10 IOs configurable as one capacitive sensing slider (5 or 10 segments)[1] and the rest as buttons or GPIOs for driving LEDs or interrupt signals based on various button conditions. The GPIOs are also configurable for waking up the device from sleep based on an interrupt input.
