The pins of stm32 have two uses: GPIO (general purpose io) and AFIO (alternate function io) For some pins (depending on the chip), neither of these two uses exists. For example, in 64-pin products, O...[Details]

STM32 has three startup modes. In RM0008 downloaded from the ST official website, you can find the startup-related configuration instructions: Translated into Chinese: The storage media corresp...[Details]

If you do not use an external crystal on the STM32, the connection method of OSC_IN and OSC_OUT If you use the internal RC oscillator instead of an external crystal, please follow the following metho...[Details]

I have encountered many problems when tinkering with LD driver recently. I will record them one by one below. Otherwise, who will remember who in five hundred years? 1. Configuration issues of multi-...[Details]
