In the actual project development process, we often need to get the running time of a section of code. The usual method is to use an oscilloscope to measure it. This blog post will use SysTick to acc...[Details]
After searching a lot of information, I finally understood the time base timer. I did not use any library functions but operated the registers directly. The following introduces the systick in STM32...[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]
After we understand the use of libopencm3, we find that libopencm3 is only suitable for small projects. Its biggest feature is the convenience of USB. So when we configure large projects, is there a ...[Details]
