How many channels in and out?

What sample rates?

Hardware solutions only, or is software DSP also OK?

Hi,

I'm very slowly exploring the potential of http://www.st.com/content/st_com/zh/products/evaluation-tools/product-evaluation-tools/mcu-eval-tools/stm32-mcu-eval-tools/stm32-mcu-nucleo/nucleo-f767zi.html.

That board has the potential for:
- SPDIF in, I2S in, Async USB in,
- sofware DSP (using outputs of Charlies ACD tools :-)
- up to 4 stereo channels (I2S or SPDIF).

But no cool configuaration tool la MiniDSP. Only C code (which as a tradeoff gives access to all the hardware features).

My objective is to have an operational USB=>Soft DSP=> 2 SPDIF stereo channels.

I propose this just in case you love those types of things and would be happy to investigate that option. This is for sure not the shortest path.

JMF

The miniDSP miniSHARC is DSP in and out. I2S, not S/PDIF.

Najda looks really nice. Does it accept external clock? Is there digital only version?

I have the stm32f769 disco board, and it rocks. You might consider it... spdif in and out, with a touchscreen and sd card slot for storage. Total cost is 80 bucks from mouser.

Thanks! This looks interesting... Do I read the specs correctly and it supports 5 I2S interfaces: 2 SAI + 6/3 SPI/I2S?
