Be wary of this. A client ordered a dozen of the cheapest SD cards he could find, only for me to find that they broke the SD spec in ways that might work on a PC card reader, but not in SPI mode using a microcontroller. I spent a lot of time trying to figure out why my code didn't work, only to later figure out that it was the SD card. --=20 Martin K. --=20 http://www.piclist.com PIC/SX FAQ & list archive View/change your membership options at http://mailman.mit.edu/mailman/listinfo/piclist .
