Hi, I'm new to C, and Im trying to program pic mcu using fat16 lib I can read/write directory/files from MMC/SD card,but having trouble with what may seem to be simple to the gifted :) can anyone give some pointers or snippet on how I can track the previous directory I was on so I can go back everytime I press ESC for instance? and/or how I can list files 4 filename at a time (I'm using 4 lines LCD), I will be placing sequential number in front of the filename, I want to be able to copy the filename to a buffer, when the number in front of the filename is use as an input, so it could be used for subsequent operation. i.e. fopen
any help would be greatly appreciated. thanks.
