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
CPU is an important part of digital processing systems. In my view, microcontrollers, microprocessors, and DSPs can all be referred to as CPUs, with their emphasis differing. Specifically, traditional microcontrollers are more focused on embedded computing, such as the commonly used 51, AVR, and ARM chips, which not only contain computational and control functions but … Read more
