Communication mode based on STM32F1 single chip microcomputer
Universal synchronous asynchronous transceiver (USART)USART introductionFull duplex asynchronous communication.The interface is connected with other devices through three pins (receive Rx, send TX and clock output CK) (at least RX and TX are required for any USART two-way communication)The sender provides a clock for synchronous transmission.Th ...

STM32 clock system
Overall design of STM32 clockClock source: pure internal (inaccurate), internal and external (the oscillation circuit generated by the clock is internal, but the crystal oscillator is external), pure external (a clock is directly connected from the outside).There are several independent clocks inside the single chip microcomputer.PLL clock: pha ...
