Using Systick timer to achieve delay 1. SysTick timer characteristics The SysTick timer is a 24-bit down counter, that is, when vlue is decremented to 0, an interrupt is triggered and the load va...[Details]
In the previous article, I wrote a simple GPIO running light test, which looked a bit monotonous. I was used to serial port debugging. If there was no serial port on the board, I had to find another ...[Details]
The day before yesterday, I learned about STM's Systick and found it quite useful for precise timing. When I used CVAVR before, I found that the delay.h in it was very useful. So, I used STM32's...[Details]
