STM32F405RG weird ADC spikes

[mbless]

I found the problem. Processing large amount of data in MATLAB was bad idea. The code I wrote process 128MB of data. Somewhere in my code data is getting corrupted I don't know why.

Now, I process the data in little chunks which results in correct output. Thank you all

I do image processing of~200MB images with several loaded in RAM at once. MATLAB is not the issue.

Probably some off-by-one, buffer overflow, or similar coding error.
