I am searching for an easy way to double buffer four channels (or more) using DMA like in the ADC_timer_dma example (at 9600hz).

I am not a programmer so it would probably take me a few weeks to be able to realise it myself. I hope someone already written a library, modified pedvide's library or can give me a hint what to do? My current solution is a cheap arduino as a sidekick, but that's not very elegant and a waste of money.
