Precise Delay Method in Cortex-M Kernel (ns Level)

by

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
