Nano FAT Library created by Andres Olivares (andyolivares@gmail.com) Version 1.2 (see CHANGELOG for details)

The driver is capable of reading a root directory and its contents (sub-directories and files) using a PIC microcontroller.

Files can be read in user selectable data chunk sizes that must be multiples of 2. For example, data can be obtained in buffers of 1, 2, 4, 8, 16, 32, 64, 128, 256 and 512 bytes. The maximum buffer size allowed is 512 bytes. Any other buffer size will produce junk data or may cause an infinite loop in the program flow.

I'm 100% sure this driver implementation is not bug free, so if you find something that could be a bug, please let me know. If you are good enough to solve it for your own, please don't forget to share the resulting code with me, so others could benefit from it. Also, I'm sure that the code can be optimized to get better performance and/or a lower footprint. If you make any change to the code, the same sharing policies mentioned before apply.

The code provided is FREE FOR PERSONAL USE. If you need to use it for commercial purposes please contact me in order to make some agreement.
