ST-Link下载Arduino IDE设置选项

通过串口下载
通过串口下载前提是已经设置好了nBOOT_SEL和nBoot0默认勾选项去掉。

需要注意一点的是，通过串口下载有几率会下载失败的情况。需要重新按一下RST复位。

修改串口1引脚
缺省的情况下，串口1是定义在PA1和PA0上的。将其修改到PA9和PA10上，可以调整，下面文件路径下的头文件的相关宏定义或者在代码中添加指定串口： Serial.setRx(PA10); Serial.setTx(PA9);

示例程序

/*
  Blink

  Turns an LED on for one second, then off for one second, repeatedly.

  Most Arduinos have an on-board LED you can control. On the UNO, MEGA and ZERO
  it is attached to digital pin 13, on MKR1000 on pin 6. LED_BUILTIN is set to
  the correct LED pin independent of which board is used.
  If you want to know what pin the on-board LED is connected to on your Arduino
  model, check the Technical Specs of your board at:
  https://www.arduino.cc/en/Main/Products
