how can i use DMA?

Question asked by Sun_Woo.Lee on Mar 30, 2017

i have been stm32F303VDT chip

 

i use DAM with ADC3 ,4 with Trigger tim2 channel 3

Perfectly done

 

but I used timer2 so I must change trigger timer 3 .

so  i  changed timer 3 channel 4 but It is not executed.

 

The procedure is start DMA  next timer Start

 

HAL_ADC_Start_DMA(&hadc3, (uint32_t*) ADC_I_Result, ADC_NUM);
HAL_ADC_Start_DMA(&hadc4, (uint32_t*) ADC_Q_Result, ADC_NUM);

 

HAL_TIM_PWM_Start (&htim3, TIM_CHANNEL_4);

 

why can i used it?
