Thanks, That helped a lot.
I found an example ...mpide-150\hardware\pic32\libraries\SD\examples\ReadWrite\ReadWrite.pde.
I also had to change the default CS pin. It is 51 on the WF32.
Thanks again. You got me looking for the right thing.
I need to archive data from a serial eeprom to the sd card on the WF32.
My problem is that I can't find a sample sketch that uses the WF32 on-board SD card for user data storage and retrieval.
There was an Instructable for using the WF32 as a Web Server. The use of the SD card was embedded somewhere.
I never could find it.
Help will be very much appreciated.
