ADC in dual simultanious mode

Hello everyone!

I have issue with initializing ADC1 and ADC2 in regular simultanious mode + DMA.

I am using CubeMx and Hal drivers. Here is my configuration.

and I start ADCs with these functions.

HAL_ADC_Start(&hadc2);

HAL_ADCEx_MultiModeStart_DMA(&hadc1,(uint32_t *)adcData,3);

but no success. Cpu hangs after calling MX_ADC2_Init().

Is there anything wrong?

Any example or guide?

thanks a lot.

Hi,

The ADC examples provided within the

http://www.st.com/content/st_com/en/products/embedded-software/mcus-embedded-software/stm32-embedded-software/stm32cube-embedded-software/stm32cubef1.html

firmware Package can be a reference for your application and it can be updated depending on your needs:

STM32Cube_FW_F1_V1.4.0\Projects\STM3210C_EVAL\Examples\ADC\ADC_DualModeInterleaved

Have a look to the following application notes about ADC:

which help you for ADC users.

You can refer to this reference manual

thanks for your reply.

I've read these documents, but still I don't know what is wrong. My configuration in CubeMx is correct and I start the ADCs just like that example. However as I mentioned CPU hangs at MX_ADC2_Init() before calling:

HAL_ADC_Start(&hadc2);

HAL_ADCEx_MultiModeStart_DMA(&hadc1,(uint32_t *)adcData,3);

Is it possible that it is CubeMx bug?

thanks in advance
