FIR filtering on STM32F4

Hi,

in my application, I need to make signal filtering using digital filters.
I take ARM's DSP library and fir example, but it is not so useful for me, because there are samples stored in memory already and they are using block of data.

What I need is:

Every time I sample a new ADC value, put it to FIR and after FIR finishes, return new value out so I can transmit it over. 
I can't wait for about 10 samples, then do stuff and send. I need to do it each time.

I have FIR coeficients already done in matlab, there is working fine.
I don't know how to properly this set up using DSP libs.

I'm using f32 variables.
If anyone have a working example for that, please send just fir filtering part.

At least, point me to a good example where I can get useful infos about that.

Thanks.
