I want to implement an interface similar to CSizingControlBar, but EVC does not support the NCCALCSIZE_PARAMS structure. I don't know if there is any way to solve this problem. Or whether such an inte...
It's been a while since I got the board, but I haven't had time to post a thread. Today I'll talk about the first power-on. The first time I burned the demo program, I used SWD debugging. After downlo...
1. Use assembly language by using the preprocessing directives #asm and #endasm. The assembly language written by the user can be followed by #asm and ended before #endasm. As shown below: #asm /*Asse...
I saw KDY master took up the banner on the forum, so I had nothing to say. I signed up, passed the review, and the board was finally sent to me! [[i] This post was last edited by ydcman on 2013-6-20 2...
I need to design a signal generating circuit with a frequency of 20M, a low level of 4V, and a high level that can be adjusted between 20V and 50V. I hope all the experts can give me some advice....
