Microsecond-Level Delay Design Solutions Generally, in an RTOS system with a clock of 1KHz, the minimum time for thread_sleep() is 1ms. In real-time control, there are situations where microsecond (us) level delays are required. What should we do in this case? There are two implementation approaches for microsecond-level delays: one is to increase the system … Read more

Introduction to FreeRTOS Interrupts The highest interrupt priority that can call interrupt-safe FreeRTOS API functions is determined by the interrupt service routine. Do not call interrupt-safe FreeRTOS API functions from any interrupt with a higher priority than this (the higher the priority, the lower the numerical value). The code is as follows (version FreeRTOS V202107.00): … Read more
Follow+Star Public Account Number, don’t miss the wonderful content Source | MultiMCU EDU Typically, the RTOS system tick is 1KHz, of course, there are cases of 100Hz or 10KHz. At 1KHz, the shortest system delay is 1ms, and in real-time control, there are situations that require microsecond (us) level delays. What should we do? There … Read more
