谢谢回复；是的，手册还没有详细看完。想先做个小测试。
#include <stdio.h>
#include "NUC1xx.h"
#include "Driver\DrvGPIO.h"
SYSCLK->PWRCON.OSC10K_EN = 1;
void main()
{
/* Enable External 12M Xtal */
DrvSYS_SetOscCtrl(E_SYS_XTL12M, ENABLE);
/* Waiting for 12M Xtal stable */
DrvSYS_Delay(5000);
/* Select UART Clock Source From 12MHz */
DrvSYS_SelectIPClockSource(E_SYS_UART_CLKSRC, 0);
DrvGPIO_Open(E_GPB,0,E_IO_OPENDRAIN);
DrvGPIO_Open(E_GPB,1,E_IO_OPENDRAIN);
while(1){
DrvGPIO_SetBit(E_GPB, 0);
DrvGPIO_SetBit(E_GPB, 1);
DrvSYS_Delay(50000);
DrvGPIO_ClrBit(E_GPB, 0);
DrvGPIO_ClrBit(E_GPB, 1);
DrvSYS_Delay(50000);
};
}
}
