Motor control by gestures with System Workbench for Linux on STM32MP1 MCU (video presentation)

In the following video we showcase an assymetric application showing interaction between real-time and multimedia activities through OpenAMP:

On Cortex A7

We run a Linux kernel and rootfs generated using System Workbench for Linux

We capture images from the camera using gstreamer

We analyze it using OpenVG to detect the number of fingers raised

We display the camera output and the analysis output in a graphical interface built with QT

Depending on the fingers configuration, we send speed and direction orders to the Cortex-M4 through OpenAMP

On Cortex M4

We receive speed and direction orders from the Cortex-A7 through OpenAMP

We control a motor, using two timers of the Cortex-M4 configured to generate PWM control signals to the motor
