When using hardware SPI1, the baud rate must be set to 2M due to project requirements. So the system clock (i.e. APB2) is set to 64M, and then divided by 32 to SPI1.Now the problem arises, the USB clo...
The light switch of the bedroom bulb is often fixed next to the door. It is very inconvenient to get up at night and look for the switch in the dark. If the switch is right next to you and can be move...
