Based on Linux Read-Write control of EERROM
Abstract
This article focuses on realizing read/writes control access method of
EEPROM under the linux development environment. The Linux operating
system as a emerming operating system, has strong core, open - source, easy to
expand and the reduction and the rich hardware support and so on, its embedded
application has the real-time processing ability, widely applies in the intelligent
equipment, the smart instrument measuring appliance, the information electric
appliance domain. Along with the computation technology to the
microminiaturization, the network direction developing, the embedded software
enhanced the tradition industrial control, medical, the work and even the home
use expense class electronic products added value and the usability enormously,
the market application prospect is extremely broad. The project necessary
software is playing the core and the soul role in the information system.
This design is in EduKit2410 experiment platform, carries on the
read-write visit through the write program in AT24C04 of EEPROM
component AT24C04, grasps the access method under the Linux of write-read in
EEPROM component, then read and compare it. Through examineing AT24C04
of EEPROM component and the processor I

the driver work is normal, comparing the result of write data and read date.
