Identify Punch and Flex Hand Gestures Using Machine Learning Algorithm on STMicroelectronics STM32 Processor Boards

Use the Embedded Coder® Coder™ Support Package for STMicroelectronics® STM32 Processor Boards to identify punch and flex hand gestures using a machine learning algorithm. The example is deployed on an STM Nucleo board that uses an external sensor (LSM6DSL) available in sensor shield (X-NUCLEO-IKS01A2) to identify the hand gestures. The output from the machine learning algorithm, after identifying whether a hand gesture is a punch or a flex, is transmitted to the serial port where 0 represents a punch and 1 represents a flex.
