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]
I encountered a problem when debugging the STM32 system clock setting: TIM2 timing 1Ms, TIM2 interrupt service function time++, LED state changes when time=100. After the program runs, I found that t...[Details]
The storage media corresponding to the three boot modes of STM32 are built-in to the chip, they are: 1. User Flash = Flash built into the chip 2.SRAM = RAM area built into the chip, which is the m...[Details]
