PIC32单片机通过文件系统实现对SD卡的读写操作，调试通过，完整代码-When using Microchip original PICTail　Daughter Board for SD/MMC cards a few pins need to be reassigned to acomodate for the different I/O selection. Things are a little more complex when using a PIC32MX4 series Processor Module on the Explorer16 as some of the pins are further swapped to free up the I/Os multiplexed with the USB port pins.
