DSP28335——6路外部中断、3路PWM

/* 有问题可咨询 HRX 6路外部中断、3路PWM pwm1下层两路 对应外部中断3 4（奇数是靠近电机 偶数是远离电机） PWM2Z轴 对应外部中断1 2 PWM3中间轴 对应外部中断5 6 */ #include "DSP2833x_Device.h" // DSP2833x Headerfile Include File #include "DSP2833x_Examples.h" // DSP2833x Examples Include File interrupt void ISRExint1(void); // ExInt1 interrupt void ISRExint2(void); // ExInt2 interrupt void ISRExint3(void); // ExInt3 interrupt void ISRExint4(void); // ExInt4 interrupt void ISRExint5(void); // ExInt5 interrupt void ISRExint6(void); // ExInt6 Uint16 *ExRamStart = (Uint16 *)0x100000; void EPwmSetup(); int flag; Uint16 i; void configtestled(void); void main(void) { InitXintf16Gpio(); //zq // InitScibGpio(); IER = 0x0000; IFR = 0x0000; InitPieCtrl(); InitPieVectTable(); // Disable CPU interrupts and clear all CPU interrupt flags: InitSysCtrl(); DINT; InitPieCtrl(); IER = 0x0000; IFR = 0x0000; InitPieVectTable(); InitExInt(); EALLOW; PieVectTable.XINT1 = &ISRExint1; PieVectTable.XINT2 = &ISRExint2; PieVectTable.XINT3 = &ISRExint3; PieVectTable.XINT4 = &ISRExint4; PieVectTable.XINT5 = &ISRExint5; PieVectTable.XINT6 = &ISRExint6; EDIS; PieCtrlRegs.PIEIER1.bit.INTx4= 1; //ExInt1 PieCtrlRegs.PIEIER1.bit.INTx5= 1; //ExInt2 PieCtrlRegs.PIEIER12.bit.INTx1= 1; //ExInt3 PieCtrlRegs.PIEIER12.bit.INTx2= 1; //ExInt4 PieCtrlRegs.PIEIER12.bit.INTx3= 1; //ExInt5 PieCtrlRegs.PIEIER12.bit.INTx4= 1; //ExInt6
