In the first two designs, the clock generation part of the rangefinder was designed. Since the clock is obtained conveniently, square waves are not very conducive to measuring phase difference in actu...
Many peripherals have the same DMA and Interrupt event source and share the same flag. How to respond if they are both enabled at the same time? According to the current definition, if you respond to ...
I used the classic picture in the Chinese manual of LM5117 to make a board. At first, there was a voltage reduction, but when I measured it again, there was no current. After that, I tested it many ti...
I came back from Beijing last night. It was a 7-day internship. Apart from visiting and attending lectures, I had the rest of the time to myself. It was like a 7-day tour of Beijing. Hahaha, I'm offic...
This program is written to simulate the serial port hardware mechanism. When used, a timed interrupt can be set with a time interval of 1/4 baud rate. The receiving function is called once for ea...[Details]
