Nucleo Boards Programming with the STM32CubelDE Sample Chapter:FreeRTOS for the STM32 MCU

摘要

Most complex real-time systems require a number of tasks (or programs) to be processed almost at the same time. For example, consider an extremely simple real-time system that is required to flash an LED at required intervals, and at the same time monitor for a keypress from a keyboard. One solution would be to scan the keyboard in a loop at regular intervals while flashing the LED at the same time. Although this approach may work for a simple example, in most complex real-time systems a multitasking approach should be implemented.
