默认调试串口是STLink虚拟的，使用串口助手连接“默认的D1D0”是接收到不数据的，因为那是Serial2。

For STM32F103C8T6 board, the default Serial is actually mapped to the 2nd serial port of the chip. This port is wired to the on-board ST-link. You can then plug your PC to the USB-port of the ST-link and get Serial Monitor on Arduino IDE right away.

串口1

Serial1的使用

/* 
HardwareSerial Serial1(PA10, PA9);

// the setup function runs once when you press reset or power the board
void setup() {
  // initialize digital pin LED_BUILTIN as an output.
  pinMode(LED_BUILTIN, OUTPUT);
  Serial.begin(115200);
  // Serial1.begin(115200);
  Serial1.begin(115200);
}

// the loop function runs over and over again forever
void loop() {
  digitalWrite(LED_BUILTIN, HIGH);  // turn the LED on (HIGH is the voltage level)
  delay(1000);                      // wait for a second
  digitalWrite(LED_BUILTIN, LOW);   // turn the LED off by making the voltage LOW
  delay(1000);                      // wait for a second
  Serial.println("Hello World! Here is Serial");
  // Serial1.println("Hello World! Here is Serial1");
  Serial1.println("Hello World! Here is Serial1");
}
