Dev Kit Description
The STEVAL-ICB002V1 daughterboard is based on the STMPE821 8-channel capacitive touch key controller. This board connects to the STEVALPCC009V3 interface board, which acts as the motherboard, to form the STM32-based capacitive touch demonstration application designed to evaluate the functioning of the STMPE821 device. The STMPE821 is a GPIO (general purpose input/output) port expander with a built-in capacitive touchkey controller. The device is capable of interfacing with a main digital ASIC/controller using the 2-line communication protocol I2C. The STM32 microcontroller is used as the main digital controller to interface the STMPE821 device, and utilizes the capacitive touchkey controller, GPIO controller and PWM controller features of the STMPE821 in the application. The STMPE821 device controls 3 different touchkeys using the integrated capacitive touchkey controller. Touch events are indicated on LEDs using the GPIO controller, and the corresponding PWM frequency is generated on a separate LED using the PWM controller.
