NAME

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

SYNOPSIS

9       eeprom [-d dev] [-a adr] [-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  (24C16s)  this  tool  works  with  1-byte
15       addresses!
16

NOTE

18       Don't forget to load your i2c chipset and the i2c-dev drivers.
19
20       Pages/addresses:
21           eeproms with more than 256 bytes appear as if they
22           were several eeproms with consecutive addresses on the bus
23           so we might as well address several separate eeproms with
24           increasing addresses
25

PARAMETERS

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