I saw a step-down circuit of the LM3478 chip, but I don't understand the peripheral circuit of the chip, especially pin 1 (Isen). According to the datasheet, it should always be in short-circuit prote...
Recently, when I was doing a synchronization test between a PC and a WinCE device, I found that there was no repllog.exe synchronization software in the WinCE system. It is said that repllog.exe must ...
I've recently been working on a PD protocol power bank, and I'm planning on making a bidirectional 65W power bank. The power supply in the PD protocol is negotiated between the source and the sink thr...
When introducing producers and consumers, it is mentioned that "get a full position" and "release an empty position". What does this mean? What is the purpose?...
I have been looking at it for an entire afternoon but still can't find any flaws. Some people say that the crystal oscillator is wrong, the delay is wrong, and what 1T and 12T, mine should be 12T, 1 m...
