实验器材:
MiniSTM32F103开发板LD3320语音模块
实验目的:
学习串口的使用，实现STM32与51单片机的串口通讯
硬件资源:
1,PB11(USART3_RX)，PB10(USART3_TX)，PA9(USART3_TX)，DS0，DS1
2,LD3320
实验现象:
当说“左侧”DS0亮，DS1灭，串口打印“code is 0”；当说“右侧”DS0灭，DS1灭，串口打印“code is 1”；当说“全开”，DS0与DS1全亮 ，串口打印“code is 2” 。
注意事项:
1,STM32串口，51串口波特率以及电脑端串口调试助手波特率均为9600。
2,51的TX端口与STM32的PB11(USART3_RX)端口连接；51的RX端口不接；STM32的PB10(USART3_RX)端口与STM32的PA9(USART1_RX)端口连接。
3,DS0，DS1均为STM32Mini板板上硬件资源。
