先看主程序

int main(void)
{

//系統(tǒng)初始化，只要就是一些時(shí)鐘配置，F(xiàn)LASH配置等等啊，對(duì)于我們初學(xué)者，先不管
SystemInit();

LED_GPIO_Config();

while (1)
{
LED1( ON ); // 亮
Delay(0x6FFFEF);
LED1( OFF ); // 滅

LED2( ON );
Delay(0x6FFFEF);
LED2( OFF );

LED3( ON );
Delay(0x6FFFEF);
LED3( OFF );

LED4( ON );
Delay(0x6FFFEF);
LED4( OFF );
}
