I recently published Recently designed M1 card reader (LPC11U14)https://bbs.eeworld.com.cn/thread-298692-1-1.html, but I have not had time to explain the card operation. After a period of hard work, I...
I recently got an LPC4357 board, but after compiling the serial port program, it didn't work well, as if the system didn't start up. The sysinit() function and UART() function were written, and the lp...
Capacitors are widely used in audio components, such as filtering, anti-cross-coupling, high-frequency compensation, DC feedback, etc. However, if we break them down by function, manufacturing materia...
The interactive interface of the industrial computer is relatively simple, so it can be optimized to use minigui or not use a third-party graphics library. It is OK if it can run on the Linux virtual ...
