urgent: generating coefficients for 2nd eq filter

Hello every one,

I am a bit confused between different Q & A that I found so far for coefficient calculation.

I have general Eq (2nd order filter) cell in my signal flow , It is set to be high pass filter.

The user can change

1- switch between Butterworth and Bessel

2- frequency

3-gain

4-slew

It is great if you send me a link or guide me how to do this conversion inside the mcu and also send the data to the DSP ( ADAU1467).

I also noticed that some of the equations or tables are not correct on the help menu.

Thanks, Semi
