Hi all, 
Thank you so much for all of your support and interest into this project so far and no credit to me at all, I have some great news. 

Hackaday user, gluons, has been working on writing the I2C drivers to correctly setup the TLV320AIC Audio Codec as well as the I2S drivers to generate sound and they were all written in MicroPython. The reason we wanted to do this is to build more confidence in the hardware design quickly so that we can now start software development  in C++ in hopes to perhaps write wrappers to already existing audio processing libraries. I have sent over a version of the DS-Pi to him and you can see what he's been able to do with it in the video linked to this post.

So the plan now is to clean up the hardware design and begin to try to use it in more typical applications. Will update you guys in due course, I will be off this summer on travel but will pick up the work again in late summer/ early autumn. When I am happy with where the hardware is, I will put the hardware up on Tindie for you guys to get your hands on it! :) 

Thank you again gluons and enjoy!
