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....
High efficiency and low standby power consumption are two major challenges in today's switching power supply design. Resonant topology or LLC topology is becoming increasingly popular because it ca...[Details]
