Is there any example source file regarding audio processing and filtering utilizing BF592 EZ-KIT?
There is a BF592 Talkthrough code posted earlier. It is available here:
Thank you for your answer. Is there any FIR or IIR filter sample codes for BF592 EZ-KIT?
There are FIR and IIR filter implementation codes for Blackfin processors in the VDSP installation directory. You can find it in the path:
...\Analog Devices\VisualDSP 5.0\Blackfin\lib\src\libdsp
Since BF59x is memory limited, one could use the Processor Tools Utility ROM as a way to include the commonly used C & DSP libraries.
This is explained in detail here: http://www.analog.com/static/imported-files/application_notes/EE-351rev2.pdf
Is now any example source file regarding audio processing and filtering utilizing BF592 EZ-KIT? I want to build a High pass filter wiht the BF592 EZ-Kit and teste this with scope? Any ideas?
Thank you Forward
Someone any Ideas about example source file about filtering on the BF592 EZ-Kit via Debug Agent?
Did you get a chance to go through the filter examples I had suggested in my earlier reply?More specifically, the codes iir_fr16.asm, iir_fr32.asm, fir_fr16.asm,fir_fr32.asm can be of help to you as I think FIR filter can be used to realize a high pass filter.
thank you for your Answer Vinod. I take here a fir_fr16.asm and try the filtering. Here is my source code.Maybe you will find my mistake.
Not sure if you are aware of, but SSM2603 codec on BF592 EZ-KIT by default enables digital high-pass filter contained in the ADC digital filters (by using ADCHPF bit in the Digital Audio Path register) to remove the DC offset from the input singal and has following chara (as mentioned in datasheet).
If you are looking for different HPF corner freq, then as Prasanth has suggested, you can realise it using functions residing in GP ROM of processor.
