I have an LG CRT monitor, bought in 2002, 17 flat screen, and now it has a problem, there is always a horizontal tilted light gray scan line, about 4 cm wide, the background is basically pure white, a...
I majored in measurement and control in my undergraduate studies, and I was exposed to 51, 430 and other single-chip microcomputers. I have heard people mention embedded systems. I would like to ask, ...
I would like to ask you seniors, for example, my load requires 3.3V voltage, 200mA continuous working current, LDO input voltage range is 1.6V~5.5V (as shown in the figure), Vin in the circuit is a ba...
Suddenly I found myself out of date. These questions were asked by eeworld experts last year or earlier. I just found out that I don't understand a lot here. Enough of the nonsense. I haven't had time...
