The lecture content itself is excellent. The explanation of techniques used in freeRTOS and methods of communication between tasks is well done. However, most people who come here don't know how to set up freeRTOS from the beginning, and that content is missing. In the end, you have to find that content and study it again from the beginning. I am willing to change my rating to 5 stars if an explanation is added on how to set up freeRTOS or how to set it up arbitrarily in other libraries.
