我正在使用ePWM 2转至2个不同的SCR，并且想要EPWM2 A之外的PWM与我想要的EPWM2B之外的PWM不同。 我该怎么做？ 这里的演示并不清楚如何使用A与B
这是我为初始化所做的操作-
#define T_PWM_BASE EPWM2_BASE // PWM A
#define U_PWM_BASE EPWM2_BASE // PWM B
//设置时基控制寄存器(TBCTL)
ePWM_setTimeBaseCounterMode (T_PWM_BASE，ePWM_counter_mode_ue_down)；
ePWM_DisablePhaseShiftLoad(T_PWM_base)；
ePWM_setPeriodLoadMode (T_PWM_BASE，ePWM_Period_Direct_load)；
ePWM_enableSyncOutPulseSource(T_PWM_base, ePWM_SYNC_Out_Pulse_on_software);
ePWM_setClockPrescaler (T_PWM_BASE，ePWM_Clock_diver_1，ePWM_HSCLOCK分配器_1)；
ePWM_setCountModeAfterSync (T_PWM_BASE，ePWM_COUNT_MODE_UP_After_sync)；
ePWM_setEmulation Mode(T_PWM_base, ePWM_emulation_free _run);
ePWM_setPhaseShift (T_PWM_BASE，0)；
//设置时基计数器寄存器(TBCTR )
ePWM_setTimeBaseCounter(T_PWM_BASE, 0);
//设置时基期间寄存器(TBPRD)
//初始设置为零
ePWM_setTimeBasePeriod (T_PWM_BASE，0)；
//设置计数器比较控制寄存器(CMPCTL)
ePWM_setCounterCompareShadowLoadMode (T_PWM_BASE，ePWM_counter_compare_A，ePWM_COMP_load_on_CNTR_ZERO)；
ePWM_setCounterCompareShadowLoadMode (U_PWM_BASE，ePWM_counter_compare_B，ePWM_COMP_load_on_CNTR_ZERO)；
//设置Action-Qualifier输出A寄存器(AQCTLA)
ePWM_setActionQualifierAction (T_PWM_BASE，ePWM_AQ_OUTPUT A，ePWM_AQ_OUTPUT高，ePWM_AQ_OUTPT_ON_TIMEBASE _UP_CMPA)；
ePWM_setActionQualifierAction (T_PWM_BASE，ePWM_AQ_OUTPT_A，ePWM_AQ_OUTPT_HIGH，ePWM_AQ_OUTPT_ON_TIMEBASE期间)；
ePWM_setActionQualifierAction (T_PWM_BASE，ePWM_AQ_OUTPUT A，ePWM_AQ_OUTPUT低，ePWM_AQ_OUTPT_ON_TIMEBASE向下_CMPA)；
ePWM_setActionQualifierAction (T_PWM_BASE，ePWM_AQ_OUTPUT A，ePWM_AQ_OUTPUT低，ePWM_AQ_OUTPT_ON_TIMEBASE _ZERO)；
ePWM_setActionQualifierAction (U_PWM_BASE，ePWM_counter_compare_B，ePWM_AQ_output_high，ePWM_AQ_output_on_timebase _up _CMBB)；
ePWM_setActionQualifierAction (U_PWM_BASE，ePWM_counter_compare_B，ePWM_AQ_output_high，ePWM_AQ_output_on_timebase)；
ePWM_setActionQualifierAction (U_PWM_BASE，ePWM_counter_compare_B，ePWM_AQ_output_low，ePWM_AQ_output_on_timebbase_down _CMBB)；
ePWM_setActionQualifierAction (U_PWM_BASE，ePWM_counter_compare_B，ePWM_AQ_output_low，ePWM_AQ_output_on_timebase _zero)；
//设置死带发生器控制寄存器(DBCTL)
ePWM_setDeadBandDelayMode(T_PWM_base, ePWM_DB_red, true)；
ePWM_setDeadBandDelayMode(T_PWM_base, ePWM_DB_FED，true)；
//选择EPWMA作为死区发生器的输入
ePWM_setRisingEdgeDeadBandDelayInput (T_PWM_BASE，ePWM_DB_INT_EPWMA)；
ePWM_setRisingEdgeDeadBandDelayInput (U_PWM_BASE，ePWM_DB_INPUT_EPWMB)；
//为有源高互补配置配置正确的极性。
ePWM_setDeadBandDelayPolarity (T_PWM_BASE，ePWM_DB_RED，ePWM_DB_POLICAL_ACTIVE_HIGH)；
ePWM_setDeadBandDelayPolarity (T_PWM_BASE，ePWM_DB_FED，ePWM_DB_POLICAL_ACTIVE_LOW)；
//设置死区上升边缘延迟寄存器(DBRD)
ePWM_setRisingEdgeDelayCount (T_PWM_BASE，SCR_DEADTIME)；
//设置死区下降边缘延迟寄存器(DBFED)
ePWM_setFallingEdgeDelayCount (T_PWM_BASE，SCR_DEADTIME)；
//设置PWM斩波器控制寄存器(PCCTL)
ePWM_DisableChopper (T_PWM_BASE)；
//设置跳闸区域选择寄存器(TZSEL)
ePWM_DisableTripZoneSignals (T_PWM_BASE，TZSEL_SIGNAL_ALL)；
//由于PWM被配置为上/下计数器，因此期间寄存器为
//设置为所需PWM周期的一半
ePWM_setTimeBasePeriod (T_PWM_BASE，SCR_PWM_FREQ)；
然后对于A与B，我尝试设置 ePWM_counter_compare_A与 ePWM_counter_compare_B
//更新T PWM占空比
void UpdateTPWM (内部双循环)
｛
fDutyCycle =双周期/ 100.0 ；
浮点周期=(浮点)(ePWM_getTimeBasePeriod (T_PWM_BASE))；
float cmpVal = fDutyCycle * Period；
ePWM_setCounterCompareValue (T_PWM_BASE，ePWM_counter_compare_A，cmpVal)；
}
//更新UCAP耦合器PWM占空比
void UpdateUCAPCoplingPWM (内部双循环)
｛
fDutyCycle =双周期/ 100.0 ；
浮点周期=(浮点)(ePWM_getTimeBasePeriod (U_PWM_BASE))；
float cmpVal = fDutyCycle * Period；
ePWM_setCounterCompareValue (U_PWM_BASE，ePWM_counter_compare_B，cmpVal)；
}
这是否能在EPWM2 A和EPWM2 B上输出不同的占空比？ 我是否错过了某些内容？
