Overview
The CapSense ExpressTM controller allows the control of 8 IOs configurable as capacitive sensing buttons or as 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. The user has the ability to configure buttons, outputs, and parameters through specific commands sent to the I2C port. The IOs have the flexibility in mapping to capacitive buttons and as standard GPIO functions such as interrupt output or input, LED drive and digital mapping of input to output using simple logical operations. This enables easy PCB trace routing and reduces the PCB size and stack up. CapSense Express products are designed for easy integration into complex products.
