这是我的程序,虽然片子不一样,但希望高手能帮忙介绍下思路,非常谢谢!

#include "p30f4012.h"

_FOSC(CSW_FSCM_OFF&HS);
_FWDT(WDT_OFF);
_FBORPOR(PBOR_OFF&MCLR_EN);
_FGS(CODE_PROT_OFF);

void delay(unsigned int tt01)
{
while(--tt01){;}
}

void __attribute__((__interrupt__))_T2Interrupt(void)
{
IFS0bits.T2IF=0;
T2CONbits.TON=0;
_RD1=!_RD1;
TMR2=0;
T1CONbits.TON=1;

}

void __attribute__((__interrupt__))_T1Interrupt(void)
{
IFS0bits.T1IF=0;
T1CONbits.TON=0;
t=TMR1;
TMR1=0;
T2CONbits.TON=1;
}

int main(void)
{
_RD1=0;
TRISD=0xFFF0;
T1CON=0x0030;
TMR1=0;
IEC0bits.T1IE=1;
IFS0bits.T1IF=0;
T1CONbits.TON=1;


T2CON=0x0030;
TMR2=0;
PR2=t;
IEC0bits.T2IE=1;
IFS0bits.T2IF=0;

delay(30000);
IFS0bits.T1IF=1;
delay(50000);

}
