iam new to sd card function with pic. iam using pic32mx795f512l connected to explorer16 board. i got example code. but in that i need to buy pictail for sd board. whether i can access the sd card without sd pictail board by connecting directly the pins of sd card to explorer16? whether i need any pull up resistors for the sd card conection with the board?
 

The SD card spec tells to place pull-up resistors for all data and cmd lines, including those that are unused in the actual operation mode. That means, you should have pull-ups for MISO (SD card SDI) and the data lines unconnected in SPI mode.
