STM32f103ZE 实现双串口通信。一个接收一个发送，同时也能动态给另外一个串口设置相关参数-STM32f103ZE dual serial communication. One receiving a transmission, but also can dynamically to another serial port settings related parameters

STM32 GPIO模拟IIC串口，实现AT24C16页读写-STM32 GPIO IIC simulation serial port and realize AT24C16 page to read and write

该源码公示了怎样使用STM32F407的串口进行收发数据，在keil5编译环境中进行编译。需要将STM32F407的串口1与USB串口相连，即可以实现电脑桌面串口调试助手的调试。-The source of the public how to use STM32F407 serial port to send and receive data, compiled in keil5 compilation environment. We need STM32F407 serial port 1 i
