I am working on a 18V to 36V boost circuit recently, but I found a problem with the inductor. When the load is reduced, the voltage drops. I adjust the feedback part to boost the voltage, but it canno...
As shown in the figure above, when does HAL248 output a low level and when does it output a high level? The explanation above is not very clear and I don’t understand it. I would like to ask the big g...
I'm using DS18B20 when doing a project. There's one part of the example program that comes with the disk that I always think has a problem. Can you help me check if it's the problem?unsigned char ID[5...
Still having the problem with applying for an English address. It seems that neither switching the language nor modifying the address can result in the application.I have no solution and went to the T...
[backcolor=rgb(239, 245, 249)]I would like to ask you a question. When the output of an AC power supply is connected to a motor, how can we prevent the reverse electromotive force of the motor, that i...
