I am a beginner in STM32. Now I want to use STM32 to measure the high level time of a pulse. I only know that I can use the capture mode of the timer, but I don’t know how to configure it after readin...
The keyboard IC is AU9462, input: USB HOST; output: keyboard matrix + 3-way USB HOST. I used this IC to expand the USB HOST, but found that the system could not start (it started under CE5.0, but enco...
[backcolor=rgb(239, 245, 249)]I would like to ask the experts, U3-19 is connected to the microcontroller pin, whether it is a high level or a low level can turn on the TLE4254, and the EN pin of the T...
