ADA2200: ACE File format for importing filters FAQs

We recently got the following question from a customer.

~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

I am using the following setup:

 

- ADA2200SDP-EVALZ  revision C

- EVAL-SDP-CB1Z  Revision 1.3

- ACE Software  Version 1.9.2639.1092

 

I’m trying to setup a Custom IIR Filter. The ACE software accepts a .txt file in the “IIR Coefficients File Path” section, at which I could place my own coefficients. But how does this file has to look like in terms of formatting and order? I could not find any information regarding this in the ADA2200 datasheet. I have also read the MT-234 file but it didn’t helped me either. Thank you in advance.

The files are formatted as:

Reg#  value

 

Where,

Reg# - is the register number as a decimal value.

Value – is the decimal register value.

 

So, to place into register 0x0011 the value 0xC0.  The file would contain:

17  192

 

I have attached a file as an example.  This file contains the coefficients from BP1 explained in MT-234.
