【瑞萨RA-eco-RA6M4评测】搭建编译环境并驱动LED灯
搭建开发板编译环境并驱动LED灯。一、下载软件
下载编译软件v6.5版，下载地址：https://github.com/renesas/fsp/releases#release-v6.5.0
下载完成后，安装软件；
二、配置硬件
2.1、在MDK工程中设置RASC
选择安装的6.5版本的rasc
2.2、配置开发板
根据开发板的硬件，配置时钟和LED灯对应的GPIO引脚
2.2.1、配置时钟
开发板上的时钟是12MHz
选择外部12MHz晶振
2.2.2、配置LED端口
LED部分电路图中对应的端口
配置LED端口
三、程序代码
3.1、fun_led.c
#include "hal_data.h"
#include "led/fun_led.h"
void init_led(void)
{
led1_off();
led2_off();
led3_off();
}
3.2、fun_led.h
