Microsecond-Level Delay Made Easy! Precise Timing Control Using STM32 Hardware Timers

In embedded development, precise delay control is crucial for many applications, especially in scenarios such as sensor sampling and protocol timing control. Traditional methods of implementing delays often rely on simple for loops; however, this approach not only lacks precision but also wastes a significant amount of CPU resources during long delays. To improve delay … Read more
