Hello everyone: This circuit seems to be a phase detector, which can separate the real part (R) and imaginary part (Xc) of impedance Z into a DC voltage output. The following is my understanding: U4C ...
I used Microsoft's built-in WIFI configuration program and tried to connect to a hotspot (TKIP+WPA2-PSK) with the wrong password. The second time it prompted "Reauthenticating chenj..." it stopped (if...

Why does the sck of spi2 of stm32103VC not have waveform output, but mosi has waveform output? I changed two chips and it's still the same. I'm so depressed. [/size][/backcolor]:Sweat: Why is it like ...
Why doesn't the mplab+picc compiler prompt the error location after the compilation fails? I need to find the error word by word. How should I set the compiler options? I'm new to PIC, please help me ...
The reason is that I didn't know anything when I was setting up the computer, and there was no serial or parallel port. Later, I found that there were external serial and parallel ports on the motherb...
