Re: how to change microphone ports in usb-audio-mic-array-software?

As the support replied to my question, it is not possible to group ports up. So there is no way to get external microphones running at the Xmos XCore Array Microphone board, as the pdm_library expects a 8-bit port as input and the expansion-header of the microphone-array board is only adrassable wit...

Re: Duplicating PDM Mic Data

I´m not a professional in Xmos-programming. But as far as I understood the lib-mic-array the function mic_array_pdm_rx ist written in assembler and you can find the code in lib_mic_array/src/pdm_rx.S .

Re: PDM-Mic to USB on xCore-200 explorer kit

I got a bit further with this project. I got the usb-functionality running and proved that my Software works, as long as I use an external 11,2896MHz clock as pdm-mclock and clocking PORT_MCLK_COUNT which is used by the usb-functions. I took this clock from the microphone-array board. But I would li...

Re: Problem Trying To Access Examples, from within xTIMEcomposer

After the problem was solved for me on both of my computers (in university and at home) my tutor installed Xtimecomposer on his laptop. Setup is the same like my university-computer: Windows 10, Java 8 update 191, same Network. But on his laptop we get the issue again. The debug.log looks like the o...

Increasing the connection timeout to 100000 works as well for my computer at university, which generated the logfile.

Re: Problem Trying To Access Examples, from within xTIMEcomposer

Thanks bear118. This problem is proving very difficult to replicate because it seems to be very specific to certain Windows computers. Myself and several colleagues have tried to replicate but so far with no luck. We are continuing to try. Please could someone who is experiencing this problem run t...

Re: how to change microphone ports in usb-audio-mic-array-software?

Thank you verry much! Is there a possibility to group 4 one-Bit ports to one 4-bit port? I can adress all microphone-pins with XS1_PORT_8B but the pins of the expansion-header are only adressable like XS1_PORT_1G, XS1_PORT_1H, XS1_PORT_1I and so on... But it would be nice if I could define a PORT_PD...
