This video shows how to program the GPIO with Model Based Design Toolbox to obtain the speed reference for the BLDC speed closed loop control system.
We discuss about:
- How to implement a simple program to read data from the GPIO
- How to test in real time with FreeMaster
- How to transform GPI pulses into a speed reference data that represents the rpm.
- How to implement from scratch a Simulink model to cover the GPIO functionality
