NAME

6       eeprom - reads and writes 24Cxx EEPROMs connected to I2C serial bus
7

SYNOPSIS

9       eeprom [-d dev] [-a addr] [-p pgs] [-w] [-y] [-f file]
10

DESCRIPTION

12       eeprom  can  be used for reading from / writing to I2C EEPROMs like the
13       popular 24C16, 24C08, 24C04, etc.  In contrast to eeprommer which  sup‐
14       ports 24C256-type EEPROMs, this tool works with 1-byte addresses!
15

NOTES

17       Don't forget to load your i2c chipset and the i2c-dev drivers.
18
19       Pages/addresses:
20           EEPROMs with more than 256 bytes appear as if they
21           were several EEPROMs with consecutive addresses on the bus
22           so we might as well address several separate EEPROMs with
23           increasing addresses
24

PARAMETERS

26       dev    device (default /dev/i2c-0)
27
28       addr   base address of EEPROM (default 0xA0)
29
30       pgs    number of pages to read (default 8)
31
32       -w     write to EEPROM (default is reading!)
33
34       -y     suppress warning when writing (default is to warn!)
35
36       -f file
37              copy  EEPROM  contents  to/from  file  (default for read is test
38              only; for write is all zeros)
