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