    New Filter Component - How To Use?

       Hi Everyone,


      How do we go about using the new filter component? I would like to try the new filter component as follows:


      1) 12 bit data input


      2) Basic Hamming window FIR lowpass filter


      12 bit sample data conceptual code:


      //Global variables


      int16 data[128] = {...};//Some array of input values that I will import from another program


      int16 output[256];//Empty array that will hold the filter's output (big enough to account for size increase due to convolution)


      uint16 i;//Counter for main loop


      void main()






           for(i = 0; i < 128; i++)






                CyDelay(1);//Be sure that filter has finished its operation


                output[i] = Filter_Read16();




      //Print the data to the test terminal upon completion




      Is this the right way to go about using the filter? How do I choose the Readxx() function? Does the Read24() function give me the highest precision? Or will the Read16() be sufficent and scale properly?
