你好，在上面你说的中断函数名是PWMInterrupt，但是本人找对应的gld文件搜索连PWM这个字眼都没有。
还有一个就是查找手册中断这一章时，本人只看到PWM错误事件和故障事件。
在代码中定义PWMInterrupt也没报错，但是也没有进入PWMInterrupt函数。下面是在下写的代码。
- void pwm1_init()//RE0,RE1
- {
- PTPER=3125-1;//控制周期，越大频率也越小，14位寄存器，最大取值=2^14=16384
- PTCONbits.PTEN = 1; //PWM time base is on
- PTCONbits.PTMOD = 0b01; // operates in a Free-Running mode
- PTCONbits.PTCKPS = 0b11; // PWM time base input clock period is TCY (1:64 prescale)
- PWMCON1bits.PMOD1 = 1; //PWM I/O pin pair is in the Independent PWM Output mod
-
- PWMCON1bits.PEN1H = 1; //PWMxH pin is enabled for PWM output
- PWMCON1bits.PEN1L = 1; //PWMxL pin is enabled for PWM output
-
- PWMCON2bits.SEVOPS = 0; //PWM Special Event Trigger Output Postscale
- PWMCON2bits.IUE = 1; // Updates to the active PDC registers are immediate
-
- PDC1 = PTPER; //控制占空比,范围是(0~2)*PTPER
- }
- void pwmINT_init()
- {
- IPC14bits.PWMIP = 0b001;
- IEC3bits.PWMIE = 0b1;
- IFS3bits.PWMIF = 0b0;
-
- }
- void __attribute__((interrupt, no_auto_psv)) _PWMInterrupt()
- {
- if(IFS3bits.PWMIF == 1)
- {
- PTCONbits.PTEN = 1;
- IFS3bits.PWMIF = 0;
- }
- }
- int main()
- {
- pwmINT_init();
- pwm1_init();
- while(1);
- }
