Recently, Nintendo updated a recruitment notice on its official website, stating that it will recruit power circuit designers (AC/DC, DC/DC) and announced specific job requirements. Nintendo may be pr
I remember when I was studying electronics, the textbook said that the average output voltage of a single-phase bridge rectifier circuit is 0.9*U2*(1+cos(alpha))/2. Why is the output of a 220V effecti
Based on the previous article on lighting up the LED light, we add a detection button input. When the button is pressed, the LED running light lights up, and when the button is released, the LED runni
The so-called constant voltage source is an output voltage that is "extremely stable" and does not change with the load. In order to ensure that the voltage remains unchanged, the output current must

Originally, I could download and debug normally using the emulator that I broke off from M0 (the compiled program also ran as expected). Now I have changed the PCB, and the debugging port of the circu
