请问下G030F6 TIM3的UP事件无法DMA 还有这个片子的96-bit unique ID 貌似也没有找到
程序如下
/* TIM3 init function */
void MX_TIM3_Init(void)
{
  LL_TIM_InitTypeDef TIM_InitStruct = {0};

  /* Peripheral clock enable */
  LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_TIM3);

  /* TIM3 DMA Init */

  /* TIM3_UP Init */
  LL_DMA_SetPeriphRequest(DMA1, LL_DMA_CHANNEL_1, LL_DMAMUX_REQ_TIM3_UP);

  LL_DMA_SetDataTransferDirection(DMA1, LL_DMA_CHANNEL_1, LL_DMA_DIRECTION_MEMORY_TO_PERIPH);

  LL_DMA_SetChannelPriorityLevel(DMA1, LL_DMA_CHANNEL_1, LL_DMA_PRIORITY_VERYHIGH);

  LL_DMA_SetMode(DMA1, LL_DMA_CHANNEL_1, LL_DMA_MODE_CIRCULAR);

  LL_DMA_SetPeriphIncMode(DMA1, LL_DMA_CHANNEL_1, LL_DMA_PERIPH_NOINCREMENT);

  LL_DMA_SetMemoryIncMode(DMA1, LL_DMA_CHANNEL_1, LL_DMA_MEMORY_INCREMENT);

  LL_DMA_SetPeriphSize(DMA1, LL_DMA_CHANNEL_1, LL_DMA_PDATAALIGN_WORD);

  LL_DMA_SetMemorySize(DMA1, LL_DMA_CHANNEL_1, LL_DMA_MDATAALIGN_WORD);

   LL_DMA_ConfigAddresses(DMA1,LL_DMA_CHANNEL_1,(unsigned int)IO_TEST,(unsigned int)&GPIOB->BSRR,LL_DMA_DIRECTION_MEMORY_TO_PERIPH);
   LL_DMA_SetDataLength(DMA1,LL_DMA_CHANNEL_1,2);//Êý¾Ý³¤¶È¶¨Î»

DMA1_Channel1->CCR |= 0X01;//Ê¹ÄÜDMA

  TIM_InitStruct.Prescaler = 8;
  TIM_InitStruct.CounterMode = LL_TIM_COUNTERMODE_UP;
  TIM_InitStruct.Autoreload = 12;
  TIM_InitStruct.ClockDivision = LL_TIM_CLOCKDIVISION_DIV1;
  LL_TIM_Init(TIM3, &TIM_InitStruct);
  LL_TIM_DisableARRPreload(TIM3);
  LL_TIM_SetClockSource(TIM3, LL_TIM_CLOCKSOURCE_INTERNAL);
  LL_TIM_SetTriggerOutput(TIM3, LL_TIM_TRGO_RESET);
  LL_TIM_DisableMasterSlaveMode(TIM3);
   TIM3->CR1 |= 0X01;

}
不知道是G0不支持还是？
