 Arduion-STM32

stm32duino 让stm32 在arduino中使用

源代码：https://github.com/stm32duino/Arduino_Core_STM32

busybox文件位置   stm32duino 下有个stm32tool 项目，内含有busybox.exe

使用usb转TTL烧写

使用 PA9 PA10 端口

PA9接 RX ,PA10接 TX ，3.3接 STM32板子的3.3V(面包板上发现5V更稳定，有时3.3无法上传）,GND接GND

usb 转ttl  TX->PA10 RX ->PA9 GND->GND 3.3V ->3.3V 

指定串口管脚用法示例
使用ST官方Arduino库，可在STM32全系列开发板上进行如下实验。

注意：实例化串口对象需要加数字编号（Serialx中的x是串口编号，取值是1,2……）：

HardwareSerial Serialx(PA10, PA9);  //将Serialx(x=1-4)串口x的管脚，一定要带编号，如：Serial1
强调一下：不能实例化默认的串口：HardwareSerial Serial(PA10, PA9)
