- Thu Jun 18, 2015 8:51 am #20821 I'm kind of behind the curve on this... how do I compile this example on a Win PC with Eclipse? The makefile is not in a format that Eclipse will digest.. or am I doing something wrong??
I have compiled other examples and modified them to my liking before so the toolchain is set right in place.
Thanks,
Nir

I am trying the delta-sigma output with a pair of computer speakers, the sound is really great.

With earphones, I have a little white noise, but the sound is good.

- Fri Jun 19, 2015 12:58 am #20881 Hello, I am planning to do a similar project http://esp8266.ru/forum/threads/internet-radioprijomnik-na-wifi-esd-12e.363/ on the basi s of this project http://www.serasidis.gr/circuits/Arduino_WebRadio_player/Arduino_WebRadio_player.htm here and I found your project, and there is a more detailed description and connection diagrams? Is there a firmware module ESP12E with 4MB flash?e ESP12E with 4MB flash?
