Recently, a reader asked this question: Why is the default configuration of the RTOS system tick (Tick) 1000? Can I set it to 100, 10000, or 2000? Many beginners have this question, including myself when I first learned about RTOS. I was confused about the different values for tick configuration and their impacts. Today, let’s … Read more
This article introduces a precise delay method in the Cortex-M kernel. Introduction Why learn this delay method? Many times when we run an operating system, we generally occupy a hardware timer – SysTick, and the clock tick of our operating system is generally set to 100-1000HZ, which means an interrupt occurs every 1ms – 10ms. … Read more
