Typically, microcontrollers are developed in a bare-metal mode, where a single while loop runs indefinitely. However, when there are multiple tasks to manage that need to switch back and forth rather than executing in a serial mode, an operating system must be assigned to the microcontroller. Common operating systems used for microcontrollers include UCOS, RTX, … Read more
