很高兴收到了瑞萨电子给与的地奇星RA6E2开发板，这个板子和STM32F103RC8T6板子很像，但是因为地奇星RA6E2是100MHz Arm® Cortex®-M33内核架构的核心板，比STM32F103RC8T6板子强一个内核级别，所以很开心，用这个板子做很多低功耗的应用了。
话不多少了，直接上干货。
论坛给出了原理图，非常的好用。
有原理图可知，LED连接的是P402引脚，所以只需要配好P402设置为输出即可
生成代码，打开KEIL工程
加入主函数，即可

板子预先的LED是闪烁的，但是闪的很快，我就改个慢的，防止蠢货说是一样的！！！！！
烧录代码，即可看到LED以1500ms的周期进行交替点亮熄灭
