stm32f207 ADC+TIMER+DMA / Poor Peripheral Library Examples

I'm looking to sample a signal (well, 2 actually - quadrature analog signals) at a fixed sample rate, but I'm baffled by the lack of any example in the Standard Peripheral Library on how to achieve this.

I would have thought that this would be a pretty standard example, i.e sample x points of a signal at y kHz and store result in memory location z.

Can anyone from ST comment on why such a basic (and imo fundamental) example is missing from the Standard Peripheral Library?

Does anybody else have an basic example of how this is achieved?  There are various incomplete snippets of code if you search in this forum, but elsewhere on the internet I've been able to find zilch.

I suspect I'm going to have to go read the manual in depth to figure this lot out...oh joy!

Many thanks.
