i'm developing a prototype for presentation using the winbond ESD17240. trying to access my audio using the 'stand alone' setting (push-buttons) was causing undesirable delays. i'm determined to get the SPI working, and your code postings are great in concert with the SPI examples on the arduino site. thanks!
my application will require asking for PLAY_PTR and REC_PTR positions. looks like i'll be able to take saturday off this week!
by the way, i've worked with the winbond chips numerous times and have nothing but good results. great documentation on their website and very helpful reps. (shocking, i know!)
