Yesterday afternoon when I was at work, I suddenly received an unfamiliar phone call. When I answered it (my boss happened to walk in at that time, I couldn't hear the words on the other end clearly),...
I recently made a circuit for SD card interface level conversion, a bidirectional circuit that converts 3.3V to 1.8V, and saw the forum activity. I applied for it by the way.Click the chip link in the...
I used the serial communication class in EVC advanced programming to receive data and the character variables can be displayed normally. I want to know how to display the hexadecimal data I received. ...
Is XINTF buffered? How many clock cycles does it take for the CPU to directly read and write XINTF? Does it not need to wait? Or does it need to wait for the number of cycles set in XTIMING?...
I recently encountered a safety capacitor. The information said that the X capacitor is connected between L and N to suppress differential mode interference. My question is: when this safety capacitor...
