stm32串口中断收发例程_查询发送中断接收，采用3.5库-stm32 serial interrupt transceiver routines _ query sent interrupt reception, with 3.5 library

使用软件: keil5 硬件资源: 1,DS0(连接在PA8) 2,串口1(波特率:9600,PA9/PA10连接在板载USB转串口芯片CH340上面) 3,ALIENTEK 2.8/3.5/4.3/7寸TFTLCD模块(通过GPIO驱动,连接关系见lcd.h) 4,按键KEY0(PC5)/KEY_UP(PA0,也称之为WK_UP) 5,DAC(STM32内部DAC通道1,通过PA4输出) 6,ADC(STM32内部ADC1_CH1,连接

STM32硬件i2c驱动MAG3110，并将地磁信号串口打印(Hardware I2C driver MAG3110)

STM32串口5的收发程序代码，程序用的是寄存器写的，有一定的参考价值。(STM32 serial 5 of the transceiver code, the program is written in register, and has a certain reference value)
