帮我写一个利用F28335编程产生应用不对称规则采样法生成的对称三相SPWM波的代码

好的，我可以回答这个问题。以下是利用F28335编程产生应用不对称规则采样法生成的对称三相SPWM波的代码：

#include <DSP2833x_Device.h>
#include <DSP2833x_Examples.h>

#define PWM_PERIOD 500 // PWM周期为500个计数器时钟周期
#define PWM_DEADBAND 100 // 死区时间为100个计数器时钟周期

Uint16 pwm1, pwm2, pwm3; // 三相PWM占空比
Uint16 pwm_deadband = PWM_DEADBAND / 2; // 死区时间的一半

void main(void)
{
    InitSysCtrl(); // 初始化系统时钟
    InitPieCtrl(); // 初始化PIE中断控制器
    InitPieVectTable(); // 初始化PIE中断向量表

    EALLOW;
    PieVectTable.EPWM1_INT = &EPWM1_ISR; // 将EPWM1中断向量表指向EPWM1_ISR函数
    EDIS;

    InitEPwm1(); // 初始化EPWM1

    IER |= M_INT3; // 使能EPWM1中断
    EINT; // 使能全局中断

    while(1)
    {
        // 产生对称三相SPWM波
        pwm1 = (Uint16)(PWM_PERIOD / 2 * (1 + sin(2 * PI * 1 / 3)));
        pwm2 = (Uint16)(PWM_PERIOD / 2 * (1 + sin(2 * PI * 2 / 3)));
        pwm3 = (Uint16)(PWM_PERIOD / 2 * (1 + sin(2 * PI * 3 / 3)));

        // 更新EPWM1的占空比
        EPwm1Regs.CMPA.half.CMPA = pwm1;
        EPwm1Regs.CMPB = pwm2;
        EPwm1Regs.CMPC = pwm3;
    }
}

    EPwm1Regs.DBCTL.bit.IN_MODE = DBA_ALL;
    EPwm1Regs.DBRED = pwm_deadband;
    EPwm1Regs.DBFED = pwm_deadband;

    // 配置EPWM1的占空比
    EPwm1Regs.CMPA.half.CMPA = ;
    EPwm1Regs.CMPB = ;
    EPwm1Regs.CMPC = ;

    // 配置EPWM1的动态比较模式
    EPwm1Regs.AQCTLA.bit.CAU = AQ_SET;
    EPwm1Regs.AQCTLA.bit.CAD = AQ_CLEAR;
    EPwm1Regs.AQCTLB.bit.CBU = AQ_SET;

    EPwm1Regs.AQCTLC.bit.CCU = AQ_SET;
    EPwm1Regs.AQCTLC.bit.CCD = AQ_CLEAR;

    EDIS;
}

interrupt void EPWM1_ISR(void)
{

    EPwm1Regs.ETCLR.bit.INT = 1;

    // 更新EPWM1的占空比
    EPwm1Regs.CMPA.half.CMPA = pwm1;
