How to use WF32 on board uSD card in Digilent Microcontroller Boards Posted May 6, 2019 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.
