The picture below is the finished board, and the result is the same as the simulation. The purpose is that the first-stage op amp collects a current signal and sends it to the second stage for amplifi...
I am using 149. When I use the multi-function programmer to burn the program, it always makes two "dong" sounds and fails to burn. In the past, when this happened, I just replaced it with a 149, but I...
The TIM3 PWM mode generates a waveform (with a fixed number), the first part is normal, but at the end, there is a momentary high level, but then it slowly becomes low, like a sawtooth peak? ? What is...
This is a document I compiled when I was doing an event before. It is a summary of some experts' experience. Maybe you have encountered such a problem before, so come and have a look.I also hope that ...
