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 OpenCV 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
