.SH NAME
|
|
eeprom \- reads and writes 24Cxx EEPROMs connected to I2C serial bus
|
|
.SH SYNOPSIS
|
|
.B eeprom
|
|
[-d dev] [-a addr] [-p pgs] [-w] [-y] [-f file]
|
|
.SH DESCRIPTION
|
|
.B eeprom
|
|
can be used for reading from / writing to I2C EEPROMs like the popular
|
|
24C16, 24C08, 24C04, etc.
|
|
In contrast to
|
|
.B eeprommer
|
|
which supports 24C256-type EEPROMs,
|
|
this tool works with 1-byte addresses!
|
|
.SH NOTES
|
|
Don't forget to load your i2c chipset and the i2c-dev drivers.
|
|
.P
|
|
Pages/addresses:
|
|
EEPROMs with more than 256 bytes appear as if they
|
|
were several EEPROMs with consecutive addresses on the bus
|
|
so we might as well address several separate EEPROMs with
|
|
increasing addresses
|
|
