简介
在上一篇文章中我们已经对环境进行了搭建,并且构建了固件。那么本章节我们将对应原理图来Toggle LED灯。

根据原理图得知,此块开发板上搭载的是一个RGBLED灯珠,其中使用LED0, LED1和LED2分别控制三颗LED的点亮。

根据代码的宏定义得知, LED1 是 红色, LED1是绿色,LED2是蓝色。

int main(void)
{
int count = 0;
printf("Hello World!\n");
while (1) {
LED_On(LED1);
MXC_Delay(500000);
LED_Off(LED1);
MXC_Delay(500000);
printf("count : %d\n", count++);
}
}原本的代码中之后LED1的点亮,我们把其他的也加上去
int main(void)
{
int count = 0;
printf("Hello World!\n");
while (1)
{
LED_On(LED1);
MXC_Delay(500000);
LED_Off(LED1);
MXC_Delay(500000);
LED_On(LED2);
MXC_Delay(500000);
LED_Off(LED2);
MXC_Delay(500000);
LED_On(LED3);
MXC_Delay(500000);
LED_Off(LED3);
MXC_Delay(500000);
printf("count : %d\n", count++);
}
}然后使用Ctrl+ shif + b 打开构建选项,选择构建。
构建完成。

然后进行烧录。

烧录成功,接下来我们来看下效果,
