Haawking-IDE 点亮LED灯

学习过程记录：
①听刘学长讲解
②看别人操作
③自己动手操作
④课后练习

具体学习内容：

int main(void)
{
InitSysCtrl(); //Initializes the System Control registers to a known state.
LED_Init();
while(1){
EALLOW; // 打开寄存器写保护
GpioDataRegs.GPASET.bit.GPIO0 = 1; // 输出高电平
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms

GpioDataRegs.GPACLEAR.bit.GPIO0 = 1; // 输出低电平
DELAY_US(30000); //30000us = 30ms

DELAY_US(30000); //30000us = 30ms
DELAY_US(30000); //30000us = 30ms
EDIS; // 关闭寄存器写保护
}
return 0;

点亮一个小灯，用延时器达到闪烁的效果
需要注意的是，DSP延时有上限只能通过叠加使用。
