各位stm32牛人，求帮小弟解答一个有关STM32的TIM和DMA应用的问题：
小弟我在制作一个逆变器，要在TIM1的CH1和CH2通道上输出SPWM波，通过DMA的Channel5响应TIM1_UP的中断把SPWM波数组按顺序传递给TIM1的CH1输出完整的SPWM脉冲，但是CH2没有办法相应DMA了，不知道各位有没有合适的办法解决这个问题？
具体部分程序如下
RCC_APB2PeriphClockCmd( RCC_APB2Periph_TIM1 ,ENABLE);
TIM_TimeBaseStructure.TIM_Prescaler = 0;
TIM_TimeBaseStructure.TIM_CounterMode = TIM_CounterMode_Up;
TIM_TimeBaseStructure.TIM_Period = TimerPeriod-1;
TIM_TimeBaseStructure.TIM_ClockDivision = 0;
TIM_TimeBaseStructure.TIM_RepetitionCounter = 0;
TIM_TimeBaseInit(TIM1, &TIM_TimeBaseStructure);
TIM_TimeBaseInit(TIM2, &TIM_TimeBaseStructure);
TIM_DMACmd(TIM1, TIM_DMA_Update, ENABLE);
TIM_OCInitStructure.TIM_OCMode = TIM_OCMode_PWM1;
TIM_OCInitStructure.TIM_OutputState = TIM_OutputState_Enable;
TIM_OCInitStructure.TIM_Pulse = 0;
TIM_OCInitStructure.TIM_OCPolarity = TIM_OCPolarity_Low;
TIM_OCInitStructure.TIM_OCIdleState = TIM_OCIdleState_Set;
TIM_OC1Init(TIM1, &TIM_OCInitStructure);
TIM_Cmd(TIM1, ENABLE);
RCC_AHBPeriphClockCmd(RCC_AHBPeriph_DMA1, ENABLE);
DMA_DeInit(DMA1_Channel5);
DMA_InitStructure.DMA_PeripheralBaseAddr = (u32)TIM1_CCR1_Address;
DMA_InitStructure.DMA_MemoryBaseAddr = (u32)&Duty_Cycle_sinewavetable;
DMA_InitStructure.DMA_DIR = DMA_DIR_PeripheralDST;
DMA_InitStructure.DMA_BufferSize =SPWM_COUNT;
DMA_InitStructure.DMA_PeripheralInc = DMA_PeripheralInc_Disable;
DMA_InitStructure.DMA_MemoryInc = DMA_MemoryInc_Enable;
DMA_InitStructure.DMA_PeripheralDataSize = DMA_PeripheralDataSize_HalfWord;
DMA_InitStructure.DMA_MemoryDataSize = DMA_MemoryDataSize_HalfWord;
DMA_InitStructure.DMA_Mode = DMA_Mode_Circular;
DMA_InitStructure.DMA_Priority = DMA_Priority_High;
DMA_InitStructure.DMA_M2M = DMA_M2M_Disable;
DMA_Init(DMA1_Channel5, &DMA_InitStructure);
DMA_Cmd(DMA1_Channel5, ENABLE);
其实我看论坛里也曾经有人遇到这个问题，不知道哪位仁兄解决了没有？http://www.openedv.com/posts/list/9367.htm
