Cubemx 4.18 ADC Configuration change

Posted on December 21, 2016 at 14:31

Good morning,

In my project I use STM32F303RC and I have two ADCs working with DMAs and triggered by a timer. ADC1 has two analog channels to be sampled, ADC4 only one. While I was working with CubeMX 4.17 I had no problems.

Then I updated CubeMX to 4.18. I did not change my program at all, but ADC1 stopped working correctly.

For some reason in the ADC1 configuration CubeMX added this part:

/**Configure the ADC multi-mode

*/

multimode.DMAAccessMode = ADC_DMAACCESSMODE_DISABLED;

multimode.TwoSamplingDelay = ADC_TWOSAMPLINGDELAY_1CYCLE;

if (HAL_ADCEx_MultiModeConfigChannel(&hadc1, &multimode) != HAL_OK)

{

Error_Handler();

}

This caused the ADC1 to work correctly only in DEBUG mode but not in RUN mode. It took me a bit to find out that this was the cause. When I remove this initialization everything works fine again.

Now, my question is very easy: Is this Multi-mode correct, and I am doing something wrong not considering it, or it is inserted when it should not be?

Thank you very much!

regards

Leo
