Hi Graham,
Thanks for the suggestions. I would not have realized the need for soldering on JP8 or the what the code meant if you hadn't pointed it out for me. I've made a solder blob to enable JP8, and I also tried to use 4, 10, 52 and 53 to SS pin (keeping the numbers consistent for lines "pinMode(10, OUTPUT);" and "if(SD.begin(10))".) However I'm getting the same results as before... "Initialization failed." ...The only ideas I can come up with at the moment is that maybe my shield is busted, or perhaps I need a different library? I have SD.h for now, and I'm not sure how I can get SDfat library.
Please let me know if you have any more suggestions. Thanks again.
