Summary
FATFs is an open source file system software stack designed
for microcontrollers to easily access multiple media sources
during run-time. This small footprint low-overhead software
supports FAT32, FAT16 and FAT12 formats using an 8.3 file
name format. FatFs can be modified to use multiple media
sources (ATA, USD, SD Card, etc.). FatFs is an open source
module that can be used, modified, and/or republished
for personal, non-profit, education, R&D or commercial use
without any restriction.
Summary
Microchip has expanded its product portfolio to include a
wide variety of cost-effective PIC® microcontrollers without an
internal data EEPROM. Many applications store non-volatile
information in the Flash program memory using table write
and read operations. Applications that need to frequently
update this data may have greater endurance requirements
than the specified Flash endurance for the device. The
alternate solution of using an external, serial EEPROM
device may not be appropriate for cost-sensitive or pin-
constrained applications. This application library presents a
third alternative that addresses these issues. This algorithm
features an interface similar to an internal data EEPROM,
uses available program memory and can improve endurance
by a factor as high as 500.
