我有把int ISR_T1_Interrupt(void)改成void ISR_T1_Interrupt(void) 不過還是不行><

請教一下:我想設定TIMER1的中斷功能並且每1ms進入中斷副程式執行。初始化時timer1相關暫存器我都有開啟(如t1_on, t1_int_enable, ti_pripr7, )並且清除t1的專斷旗標。但是不巧的是他初始化完就一直於主程式迴圈裡並不會因timer1計數1ms就進入中斷副程式。我不曉得是我站存器少設了什麼還是要有特別的指令去呼叫持是過來執行中斷副程式，我是只用c language. 麻煩你了^^

#define __dsPIC30F2020__
#include <p30F2020.h>
#include <timer.h>
#define FCY 424628450/32 //CLK/8/4

void Init_TMR1(void);

unsigned char second = 0;
unsigned char onesecond = 0;
unsigned int milisec = 0;



int ISR_T1_Interrupt(void)
{
milisec = milisec+1 ;
if(milisec == 1000)
{
milisec = 0;
onesecond = 1;
}
IFS0bits.T1IF = 0;
}

int main(void)
{
ADPCFG = 0XFFFF;
TRISB = 0X0000;

Init_TMR1();
onesecond = 0;
while(1)
{
if(onesecond)
{
onesecond = 0;
second = second+1;
LATB = second;
}

}

}



void Init_TMR1(void)
{
IEC0bits.T1IE = 1 ;//Enable the interrupt function
IFS0bits.T1IF = 0 ;//Clear the interrupt flag for initial setting
IPC0 = 0x7000 ; //The highest Priority level 7
PR1 = FCY/1000 ; //Calculate the FCY with 1m Sec
T1CON = 0x8000 ; //Turn on timer1, prescale 1:1
