Suggest improvements in my data acquisition system

[vishwas1523]

so this is my data acquisition system, i want you to suggest some improvements in it. as the adc + dma ping pong buffer is working fine, but after that the conversion and its transmission via dma+uart ping-pong buffer is so much miserable. there is no synch between these buffers.
here is my project:

PS: i am using stm32 nucleo f446re

Basically your way ADC- > DMA - > 2 buffers , is good.

But to get it automatic in sync , just set the DMA to circular and use callbacks .

In half / full callback you move the data from the block to your ...big buffer for analysis, or whatever you want to do.

to enable callbacks generated by Cube:
