Audio Lite

[ik1xpv]

Hello List,

Referring to  low cost audio interface to add to Hermes-Lite (

https://groups.google.com/forum/#!msg/hermes-lite/LL2rtrSgdEY/QCAnPJ5fk-YJ ),

I had some results using a sigma delta DAC implemented into the FPGA.

I tried to save the code and some documentation in a fork of Hermes Lite at

https://github.com/ik1xpv/Hermes-Lite/

In the documentation 

https://github.com/ik1xpv/Hermes-Lite/blob/master/README.md

there are links to audio recordings. 

The samples have been recorded using a second PC running Audacity connected via cable to Hermes-Lite.

I apologize for my English and for errors in my first time use of Github.

Wow!  Congratulations Oscar!  That is a capital idea, and it sounds good too.

Very nice - simple, elegant, inexpensive and sounds great! I will add it to the next revision of the frontend card. Thanks for the detailed documentation and pictures. I have linked to your github fork and Rob's from the list welcome message and from the main github page now. Thanks also for digging into the RTL. Once I get what I am working on in order, I will pull in your changes.

73,

Steve
