中斷函數宣告錯誤了，改一下:
void __attribute__((interrupt, no_auto_psv)) _T1Interrupt(void)

程式中RA0腳位為輸出timer1所中斷的時間週期但是RA0卻都一直維持在初值所設定的HIGH電位~請問有大大知道問題出在哪嘛?
#include <p33FJ12MC201.h> _FGS (GSS_OFF & GCP_OFF& GWRP_OFF); _FOSCSEL(FNOSC_PRIPLL & IESO_OFF); _FOSC (FCKSM_CSDCMD & OSCIOFNC_OFF & POSCMD_HS); _FWDT(FWDTEN_OFF); _FPOR(PWMPIN_ON & HPOL_ON & LPOL_OFF & FPWRT_PWR1); _FICD ( JTAGEN_OFF & ICS_PGD1); int main(void) { ADPCFG=0xffff; TRISA = 0xfffe; LATA = 0x0001; IPC0bits.T1IP = 6; IEC0bits.T1IE = 0; T1CON = 0x8000; PR1 = 2949; while(1) { } } void __T1Interrupt(void) { PORTAbits.RA0 = ~PORTAbits.RA0 ; IFS0bits.T1IF = 0; }
