Accel 2 Click Mikroe Accel 2 Click features the STMicroelectronics LIS3DSH 3-axis accelerometer. The LIS3DSH embeds a FIFO buffer and two programmable state machines. This allows the developer to implement gesture recognition. User-defined programs can distinguish movement patterns like shake and double shake, face up or down, turn and double turn, and activate an interrupt upon their execution. Either I²C and SPI interfaces are available for communication with Mikroe Accel 2 Click and the target MCU.
