Hello,

I am using ADC in triple regular simultaneously mode (circular mode using FIFO half threshold). EXTI11 is used for trigger the ADC.when I am reading ADC's value it is not coming in sequence .

When external trigger is timer(TIM2) then  I am getting all value in sequence.

How can I resolve this problem?

Thanks in advance.

Regards,

Make sure EXTI11 signal doesn't bounce. Check with a scope, making sure how frequently it triggers.
