Since the product requires a multi-output power supply, I used UC3842, and the circuit was referenced from someone else on the Internet.Now there are two situations in the debugging process: 1. The in
[size=4] Hex 80 is sent as a sync character before each transmission. The device acknowledges with hex 90. The data frame is then sent. Each frame begins with a header byte = hex 80. The other bytes o
Many years ago, a developer, seeking a deeper understanding of embedded systems, asked this question: How can I know and understand what my system is doing?
I was a little surprised by this question b
As shown in the figure, the D15 diode at the secondary end of the switching power supply has its open measurement waveform as shown below, green is the current, and orange is the voltage:
