The Real Time Clock (RTC) is a set of counters that measure time. It can continue to run even when the system loses power. The RTC clock in the LPC1768 microcontroller can be a separate 32Khz clock so...
I wrote a program similar to a plug-in for a software in wince. However, when I am operating the software, I don’t want others to see the process, so I hope to implement a function similar to a screen...
Circuit boards are the carriers of electronic circuits. Any circuit design needs to be installed on a circuit board to realize its function. Processing circuit boards is the most headache for amateur ...
It took me several months to make and write the code. Please support me. Using the 51+pdiusbd12 structure, I realized the HID device class and the custom device class. The HID device class has standar...
There are two problems. One is as shown in the figure, the output is this kind of wave, what I want is a square wave. The second is that no matter which pin I use as the output, P4.2 outputs a square ...
