FreeRTOS on the Raspberry Pi Pico (RP2040) Part 4: Mutex

FreeRTOS is an open source Real Time OS available for a wide range of microcontrollers and this video is part 4 in a series on using FreeRTOS on RP2040 based boards such as the Raspberry Pi Pico. In this video we show you how the FreeRTOS mutexes work and we briefly cover how to use mutexes, what they are and when not to use them. By the end of this tutorial you will have a project which explains how mutexes can affect and protect shared resources.
