Hello everyone, I use three adc blocks including ADC1, ADC2, ADC 3, and DMA to transmit data. However, DMA data transmission has lost data. Below is my code.

Looking forward to hearing from everyone.
Thanks you,

Your code miss dont use any DMA callback and too mix
ADC_EOC_SINGLE_CONV
plus AD1 AD2 ends two conversion in other moment as AD3 only one...
2022-12-10 07:57 PM
Can you say more about this? Where do I need to fix it now?
Looking forward to your reply.
Thanks you.

Can yu write more about what loses? Why you use EXTI for peak ?
Open and learn from examples in repository folder.
2022-12-11 12:54 AM
I am controlling the peak detector circuit. Therefore, it is necessary to use external interrupts. I've looked at examples and hardly any of these work.
2022-12-11 01:24 AM
Still nobody see here what loses?

In the following result, channels S, A, and C should be equal. but sometimes it's not equal or not nearly equal. look at the underlined values.
