decode-dimms

Decode the information found in memory module SPD EEPROMs

root@kali:~# decode-dimms -h
Usage: /usr/bin/decode-dimms [-c] [-f [-b]] [-x|-X file [files..]]
       /usr/bin/decode-dimms -h

  -f, --format            Print nice html output
  -b, --bodyonly          Don't print html header
                          (useful for postprocessing the output)
      --side-by-side      Display all DIMMs side-by-side if possible
      --merge-cells       Merge neighbour cells with identical values
                          (side-by-side output only, default)
      --no-merge-cells    Don't merge neighbour cells with identical values
                          (side-by-side output only)
  -c, --checksum          Decode completely even if checksum fails
  -x,                     Read data from hexdump files
  -X,                     Same as -x except treat multibyte hex
                          data as little endian
  -h, --help              Display this usage summary

Hexdumps can be the output from hexdump, hexdump -C, i2cdump, eeprog and
likely many other progams producing hex dumps of one kind or another.  Note
that the default output of "hexdump" will be byte-swapped on little-endian
systems and you must use -X instead of -x, otherwise the dump will not be
parsed correctly.  It is better to use "hexdump -C", which is not ambiguous.

decode-edid

decode-vaio

Decode the information found in the Sony Vaio laptop identification EEPROMs

root@kali:~# decode-vaio -h
# Sony Vaio EEPROM Decoder version 1.7 by Jean Delvare

Vaio EEPROM not found.  Please make sure that the at24 or eeprom module is loaded.

i2c-stub-from-dump

Feed i2c-stub with dump files

root@kali:~# i2c-stub-from-dump -h
Usage: i2c-stub-from-dump <addr>[,<addr>,...] <dump file> [<dump file> ...]

i2cdetect

Detect I2C chips

root@kali:~# i2cdetect -h
Usage: i2cdetect [-y] [-a] [-q|-r] I2CBUS [FIRST LAST]
       i2cdetect -F I2CBUS
       i2cdetect -l
  I2CBUS is an integer or an I2C bus name
  If provided, FIRST and LAST limit the probing range.

i2cdump

Examine I2C registers

root@kali:~# i2cdump -h
Usage: i2cdump [-f] [-y] [-r first-last] [-a] I2CBUS ADDRESS [MODE [BANK [BANKREG]]]
  I2CBUS is an integer or an I2C bus name
  ADDRESS is an integer (0x08 - 0x77, or 0x00 - 0x7f if -a is given)
  MODE is one of:
    b (byte, default)
    w (word)
    W (word on even register addresses)
    i (I2C block)
    c (consecutive byte)
    Append p for SMBus PEC

i2cget

Read from I2C/SMBus chip registers

root@kali:~# i2cget -h
Usage: i2cget [-f] [-y] [-a] I2CBUS CHIP-ADDRESS [DATA-ADDRESS [MODE [LENGTH]]]
  I2CBUS is an integer or an I2C bus name
  ADDRESS is an integer (0x08 - 0x77, or 0x00 - 0x7f if -a is given)
  MODE is one of:
    b (read byte data, default)
    w (read word data)
    c (write byte/read byte)
    s (read SMBus block data)
    i (read I2C block data)
    Append p for SMBus PEC
  LENGTH is the I2C block data length (between 1 and 32, default 32)

i2cset

Set I2C registers

root@kali:~# i2cset -h
Usage: i2cset [-f] [-y] [-m MASK] [-r] [-a] I2CBUS CHIP-ADDRESS DATA-ADDRESS [VALUE] ... [MODE]
  I2CBUS is an integer or an I2C bus name
  ADDRESS is an integer (0x08 - 0x77, or 0x00 - 0x7f if -a is given)
  MODE is one of:
    c (byte, no value)
    b (byte data, default)
    w (word data)
    i (I2C block data)
    s (SMBus block data)
    Append p for SMBus PEC

i2ctransfer

Send user-defined I2C messages in one transfer

root@kali:~# i2ctransfer -h
Usage: i2ctransfer [OPTIONS] I2CBUS DESC [DATA] [DESC [DATA]]...
  OPTIONS: -a allow even reserved addresses
           -b print read data as binary, disables -v
           -f force access even if address is marked used
           -h this help text
           -v verbose mode
           -V version info
           -y yes to all confirmations
  I2CBUS is an integer or an I2C bus name
  DESC describes the transfer in the form: {r|w}LENGTH[@address]
    1) read/write-flag 2) LENGTH (range 0-65535, or '?')
    3) I2C address (use last one if omitted)
  DATA are LENGTH bytes for a write message. They can be shortened by a suffix:
    = (keep value constant until LENGTH)
    + (increase value by 1 until LENGTH)
    - (decrease value by 1 until LENGTH)
    p (use pseudo random generator until LENGTH with value as seed)

Example (bus 0, read 8 byte at offset 0x64 from EEPROM at 0x50):
  # i2ctransfer 0 w1@0x50 0x64 r8
Example (same EEPROM, at offset 0x42 write 0xff 0xfe ... 0xf0):
  # i2ctransfer 0 w17@0x50 0x42 0xff-

libi2c-dev

I2C devices are usually controlled by a kernel driver. Using this library it is also possible to access all devices on an adapter from userspace and without the knowledge of Linux kernel internals.

This package contains what you need for compiling sources that use this library in your own code.

Installed size: 34 KB
How to install: sudo apt install libi2c-dev

libi2c0

python3-smbus

This Python 3 module allows SMBus access through the I2C /dev interface on Linux hosts. The host kernel must have I2C support, I2C device interface support, and a bus adapter driver.
