HAL_TIMEx_MasterConfigSynchronization(&htim8, &sMasterConfig);

Configures the Master TIM to generate

a triggering event

(TIM_TRGO_UPDATE).

hadc1.Init.ExternalTrigConv = ADC_EXTERNALTRIGCONV_T8_TRGO;

hadc1.Init.DMAContinuousRequests = ENABLE;

hadc1.Init.EOCSelection = ENABLE;

HAL_ADC_Init(&hadc1);

The TIM8_TRGO event triggers

conversion for the regular group with

rising edge.

Since converted regular channel

values are stored into a unique data

DMA handle __HAL_LINKDMA(hadc, DMA_Handle, hdma_adc);

Associates the initialized DMA handle

to the ADC handle.
