Is there any schematic diagram or development board description for three-phase asynchronous motor frequency conversion control based on STM32? I have seen brushless DC motors at the exhibition, but t...
I have experienced this myself, and it often happens in the group. The board is not soldered with a 32K crystal, but it works normally when you touch it, or it works sometimes well and sometimes not. ...
I now have an embedded liunux system board with a WLAN module. Now I hope it can communicate with the PC. After setting up the AP, it has always been able to communicate, but then after a period of ti...
To meet Xinxin's request, in order to complete this small project, although it is a software part, hardware debugging is also necessary. I dug out the 51 things that have been put away for a long time...
