When I applied for the display screen, I thought about developing and applying the NUCLEO-F746ZG motor into a product type, without flying wires, and it would look better. Now, after a week of concept...
I am very happy during the Chinese New Year, but after the Chinese New Year many companies will lay off employees. What do you think? Many companies in Shanghai are actively laying off employees. I am...
My idea is to use E3F-5DN1 photoelectric switch to drive P521 optocoupler. The photoelectric switch is NPN normally open and connected to 12V power supply. The photoelectric output is connected in ser...
I would like to ask all the experts, how should I choose the chip I need? Now I don’t even have the model, and the required functions are simple, so a 51 chip will do. Can you provide some chips for m...
When creating the wince platform, SMDK2410 - 1 error(s), 0 warning(s) appears during compilation, and in build.log it appears: 'findstr' is not recognized as an internal or external command, operable ...
I recently bought a DC water pump, 24v5A, and the power supply is a low-quality switching power supply, also 5A. I am a little worried that the startup current of the water pump is too large, but it s...
