I'm getting basically the same problem, making the arrays passed into the filter function global only works when I call the same arrays. I getting the error again when I call 'dsp_filters_biquad()' twice but with different global arrays each time: samples[0] = dsp_filters_biquad(l_sample[0], b_c1, b...

Hi Andrew, I know this is an old thread, but I am very much interested in applying 8 channel FIRs of 2048 taps but at 16kHz using my XK-AUDIO-216-MC-AB MultiChannel Audio Platform if possible. I'm having problems inserting the DSP core while applying the convolution funciton 'dsp_filters_fir' from t...

I'm getting the same 'error: multi-tile main must consist of single non-empty par statements' and the above does not seem to work for me. I'm try to modify modify the 'app_usb_aud_xk_216_mc' application to first read data from a .txt file into an array that I will use as my FIR filter. I want to do ...

OK, I got it working. Weird, I tried placing the 'test.txt' file back in \AN10122_stimecomposer_reading_from_a_file\ and it successfully opened and printed to the Console. This was after I successfully ran the opposite AN10123 application, which WRITES to 'test.txt' file defaulted to location \AN101...

Hi. Strange, even when I place the test.txt file in \AN10122_xtimecomposer_reading_from_a_file\bin\ I get the same 'Error: _open failed' error. I see that the .xe is also in \bin\.

I'm trying to run the 'AN10122_xtimecoposer_reading_from_a_file' project, associated with the application note AN10122. I get error 'Error: _open failed' and am not sure why. - I was able to Build the project without any problems; I only had problems running it. - I'm using xTIMEcomposer ver 14.3.3 ...

1) Section 5.7.2 of the guide says for adding DSP I will probably want to free up Core functionality. I am not using SPDIF, ADAT, or MIDI. How could I do this? Would I just set the defined 'SPDIF_TX' in 'customdefines.h' of the 'app_usb_aud_xk_216_mc' application to 0? Is seems the other audio inter...

Thanks akp. That worked! I used a breakout board equipped with electret microphone and adjustable amplifier. For others trying to do that same thing, the microphones worked pretty well by powering the amplifier Vcc from the 5VA-GND3 header on the XCORE-200 MC board.

I recieved the same 'Unhandled exception: LOAD_STORE, data:xxxxxx' bug when implementing the 'dsp_filters_fir()' function of the 'lib_dsp' library, in a simulation using a signal array and a FIR. I noticed that these two arrays were declared inside main(). When I placed in outside of main as global ...

Hi infiniteimprobability, In regards to your post above on Thu Jan 18, 2018 11:48 pm - thank you this is a helpful template for DSP on real-time audio! I'm just now trying to equate this with the recommendations for writing DSP code for real audio described in Section 5.7.2 of 'USB Audio Design Guid...
