STM32CubeMX6.3.0 DAC+DMA+TIM

I use STM32CubeMX6.3.0 to config DAC ,DMA ,TIM2,and gererate projec for MDK,

the initial order is below(auto create by STM32CubeMX6.3.0):

 MX_GPIO_Init();

MX_DAC_Init();

MX_DMA_Init();

 MX_TIM2_Init();

​then I create a buffer for sin wave,data,and start DAC:

HAL_TIM_Base_Start(&htim2);

 HAL_DAC_Start_DMA(&hdac,DAC_CHANNEL_1,(uint32_t *)sin_wave,256,DAC_ALIGN_12B_R);

​but no wave !

I must change the initial order manually to below:

 MX_GPIO_Init();

MX_DMA_Init();

MX_DAC_Init();

 MX_TIM2_Init();

then the sin wave is generated by DAC+DMA+TIM2.

is this a bug for STM32CubeMX6.3.0?

Hi @bmo.1​ ,

This issue should be already fixed with STM32CubeMX 6.4 available currently.
