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]
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]
background After the hardware engineer completed the PCB and schematic design, the routine was modified according to the tutorial of Zhengdian Atom to verify the correctness of the hardware. STM32F...[Details]
Although it is early summer, the Chinese smartphone market is still in the cold winter, just like Beijing in April with snow. For mobile phone brands caught in the middle, the cold is even more bit...[Details]
Recently, the "Smart Photovoltaic Industry Development Action Plan (2018-2020)" jointly issued by six departments has put this concept on the forefront. Photovoltaic smart solutions will become the ne...[Details]
Timing and protocol are two key points in digital system debugging, and they are also where logic analyzers can play their most valuable role. How can we use a logic analyzer to quickly complete wiri...[Details]
