Re: When will there be SliceKits available?

MuellerNick - It is going to take a little while to get these back in the distribution network. As a gesture of goodwill, how about we ship you a bare (tested) board without all of the usual kit contents?

If this works for you, can you provide a shipping address (PM me).

Re: When will there be SliceKits available?

OK, there has been some movement on this although not a firm date quite yet. We have located some stock but it needs to be re-tested. The person responsible for this is out of office currently so I'll hope to get an answer on ETA next week.

Re: XCORE-200 Multichannel Audio DSP App Note?

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 inte...
