STM32F103VET6基于Arduino开发框架下串口和软串口通讯示例

• 📌相关篇《【硬件开源电路】STM32F103VCT6开发板》

• 🌺通讯演示：
  

✨本示例来源于STM32核心固件自带例程。

• 📢对于STM32F103VET6芯片，Arduino开发环境下，默认串口是：PA10，PA9，对于不同系列的STM32默认串口引脚不一定是这个两个引脚上，这一点需要注意。

📝示例代码

/*
  Software serial multiple serial test

 Receives from the hardware serial, sends to software serial.
 Receives from software serial, sends to hardware serial.

 The circuit:
 * RX is digital pin 10 (connect to TX of other device)
 * TX is digital pin 11 (connect to RX of other device)

#include <SoftwareSerial.h>

SoftwareSerial mySerial(PC11, PC10); // RX, TX

void setup() 
  // Open serial communications and wait for port to open:
   Serial.begin(115200, SERIAL_8N1);//PA10,PA9
  while (!Serial) 
    ; // wait for serial port to connect. Needed for native USB port only
  


  Serial.println("Goodnight moon!");

  // set the data rate for the SoftwareSerial port
  mySerial.begin(4800);
  mySerial.println("Hello, world?");


void loop()  // run over and over
  if (mySerial.available()) 
    Serial.write(mySerial.read());
  
  if (Serial.available()) 
    mySerial.write(Serial.read());
