Here, it’s worth mentioning that a design encompassing all three requirements will merit the use of a full-fledged operating system.

WebRTOS APIs. The RTOS APIs handle creation and destruction of threads in Arm Mbed OS 5, as well as mechanisms for safe interthread communication. Threads are a core component of Mbed OS 5 (even your main function starts in a thread of its own), so understanding how to work with them is an important part of developing applications for Mbed OS 5. WebAn in-depth explanation of the tasks and their distribution among the three microcontrollers follows.
