I recently read "Carbon Empire" written by Bai Haijun, and I always felt like writing something. The author thinks:
Global warming is a big lie, and the slogan of low-carbon economy is a political plo...
I learned about makefile today and tried to write a very simple makefile, but it always gives me an error. There is a tab before the command line, and the encoding is utf-8. When I enter the command l...
When I was studying, I didn't connect it to the "Microcomputer Principles" I learned some time ago. In fact, it talked about buses and timing diagrams.
But I didn’t think about it when I was learning ...
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
Traditional broadcasting systems generally need to be operated manually at a fixed time, and can only realize one-way broadcasting with few functions. Traditional bell ringing equipment has a singl...[Details]
