what doesnt work about the software SPI library? you will probably have to change how the SS pin operates

I was able to get the software SPI (i.e SCK pin wave) sync with the SS pin wave at the first bit.I will see if I am getting any sound from the codec at this point and then will later try and replicate the same in edison.

The above are my oscilloscope shots for the SS pin (yellow) and SCK pin(green).The first SCK pulse is actually little wider in width.Will it work?

Software SPI is working on the Due . Now I will try and replciate it on the edison.

looking at your picture again, there are 9 pulses on the first transfer. there should only be 8.
