I'm wondering, when I was drawing a PCB, the top wiring was red, but it turned green once it was connected to the pad. What's going on? It's fine if it's not connected. The bottom blue wiring is also ...
It's nothing, I just saw the forum statistics that the number of water versions today has reached 199, so I came to make it the 200th, which is also a small historical moment....
When using AD to sample the power frequency voltage signal, after conditioning, the signal is sampled at 0.2V-2.8V for 50us. Because multiple zero-crossing signals may be sent by mistake due to interf...
