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
Ⅰ Introduction In addition to the “General Configuration” in the FreeRTOSConfig.h configuration file, the content of other configurations is relatively less used by beginners and is also relatively difficult to understand. To give beginners a general understanding, this article continues to discuss the content of FreeRTOSConfig.h configuration, and further discussions will be combined with applications … Read more
