【简介】
本文讲述了如何使用Clion开发GD32H7
【前言】
与Clion开发stm32的配置类似，只需要添加GD32特定的OpenOCD工具，以及更改GD32对应的GCC编译链接库，启动文件等资源即可，还有烧录时候的配置文件。具体配置过程请看：https://www.cnblogs.com/xutongxin/articles/17609760.html
【串口重定向】
printf
int _write (int fd, char *pBuffer, int size)
{
for (int i = 0; i < size; i++)
{
while(RESET == usart_flag_get(USART0, USART_FLAG_TC));//等待上一次串口数据发送完成
usart_data_transmit(USART0, pBuffer[i]);//写DR,串口1将发送数据
}
return size;
}
