The DMA serves the EOC (self clearing), you'd be better using the DMA TC or HT signals.

I see HTIF but not TCIF and there is no error since none the other flags for stream 0 in DMA_LISR are not set..

(In my code, ADC_DMA_STREAM is DMA2_Stream0).

Strangely, by inspecting the destination array it looks as though it converted 4 of the 6 values (well, 3. the first one is zero) but DMA_S0NDTR is still 6 when I pause and look from the debugger meaning that it has not transferred any values at all.
