How to receive 16 I2S channels

Hi guys, my goal is to receive 16 I2S channels from 16 audio sources. The USB Audio Reference project operates with I2S via 1-bit ports. Does anyone try to connect 4*I2S channels to 4-bit port or 8*I2S channels to 8-bit port and get audio data? Yes, in this case, I have to modify audio.xc and use ma...

Re: 64ch USB audio driver cannot be recognized by the windowsPC, but 61ch can.

Hi stanrance,
could you please explain your realization of connecting 8 pcs. CS5368 to the XMOS?
Do you use 8 TDM interfaces or 32 I2S interfaces?
Do you use lib_i2s with arrays of 1-bit ports or do you modify lib_i2s to use multi-bit ports?

Re: Generate and update factory image, replace factory with dfu

Hi twittich, I work with USB Audio project but the main idea is the same. I burn into the FLASH 3 items: Loader + "factory" firmware image with DFU + current firmware image (with or without DFU). The Loader polls the button state on the board at the power-up and boots either "factory&...

Re: dfu

"dfucons info" shows only devices with DFU interface. XMOS xtag-3 has not DFU interface. Be sure DFU is enabled in your "xmos microphone array control" firmware.

Re: DFU Process got stuck in XU224 board

Hi,
I did nothing for my XE216 board. Build error appeared when I built my test branch. DFU in original project works correctly.

Try to clean project before build or manually delete .build & bin folders.
I use xTIMEcomposer 14.2.4

Re: AN00231 SPDIF-Receive-to-I2S-output-using-ASRC x->192kHz

Are you sure you have set #define DEFAULT_FREQ_HZ_I2S 192000 ? non_fs in your console output is 0x1000000. It's like i2s rate is 48k. check main.xc -> asrc() uses defines, not digital values fs_code_t in_fs_code = samp_rate_to_code(DEFAULT_FREQ_HZ_SPDIF); //Sample rate code 0..5 fs_code_t out_fs_cod...
