STM32G070RBT6基于Arduino框架下点灯程序

---

✨说明：Arduino STM32系列开发环境搭建不在本示例范围内。

• 相关篇《【硬件开源电路】STM32G070RBT6开发板》
  

自制成本不超过10块钱.

通过ST-Link烧录演示

• 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。
• 串口下载Arduino IDE设置选项

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。

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:
