Can someone confirm whether the TDM mode can be operated in slave mode (FS is an input to the XCore). The example AN00162_i2s only talks about TDM master mode but talks about both master and slave modes for i2s.
Thanks,
Shaminda

Re: TDM signal capture using xCore multi channel audio EVM
Yes, the array microphone product seems very interesting. I have already contacted xMOS sales department to purchase the microphone array. However it is only offered to selected customers at this point and I am waiting for a response. If you are from XMOS can I directly reach out to you do discuss p...

Re: TDM signal capture using xCore multi channel audio EVM
I think I clearly need to modify the software to receive the TDM format of the mic array. The mic array uses a TI codec chip that uses TI DSP (TDM) format (The lines; bit clock, FS and data. Frame sync is followed by a multi channel data stream as shown). Does anyone have an idea what software examp...

Re: TDM signal capture using xCore multi channel audio EVM
Yes, The microphone array emits a time division multiplexed signal (7 microphone channels ) as shown in the .png file (contains data, bit clock and frame sync signals). I need to capture the audio using the host.

TDM signal capture using xCore multi channel audio EVM
Hi, I am trying to get a multi channel TDM signal captured and sent to Matlab data acquisition toolbox. To convert TDM to USB I am trying to us the xCORE-200 multichannel Audio dev board. I am new to xCORE and would really appreciate if you can point to a good example to get started. The microphone ...

TDM to USB audio
<t>Status: Under development<br/> License: BSD<br/> <br/> The objective of the project is to obtian a TDM multi microphone array signal by the computer using USB interface. The xCORE -200 audio platfrom is used here. There are 5 input TDM channels and the microphone array in in the master mode. My o...
