PWM -> ADC & DMA

[oeliks]

Hi, I want to​ trigger ADC with PWM, transfer it to array by DMA.

But first I have problem with setting dma.

......

Question 1.

Do I have to start HAL_ADC_Start before I use HAL_ADC​_Start_DMA

Or will this second function start adc & dma?

Question 2.

Want to set buffer that will collect 10 samples on single channel adc.

Buffer[10];

HAL_ADC_Start_DMA((&hadc), (uint32_t*)Buffer, 1);

​will this work?
