I wa <noauthor@nospam.com> http://www.8051projects.net/forum-t9363.html what controller you are using?Fa32t library available online.. and can be ported to any AVR, PIC and ARM controller.[link]http://www Ajay<contact@nospam.com> http://www.8051projects.net/forum-t9363.html hi ajay thank for the fat32 link. i will go thro' it. yet I have not desided uc. but I am thinking to use one of from PIC32MX familily.
