eeprog(8) System Administration eeprog(8)NAME
eeprog - reads and writes 24Cxx EEPROMs connected to I2C serial bus.
SYNOPSIS
eeprog [-fqxdh] [-16|-8] [-r addr[:count]|-w addr] <device> <i2c-addr>
DESCRIPTION
eeprog uses the SMBus protocol used by most of the recent chipsets.
NOTE
Don't forget to load your i2c chipset and the i2c-dev drivers.
The following environment variables could be set instead of the command line arguments:
EEPROG_DEV device
EEPROG_I2C_ADDR i2c-addr
PARAMETERS
Address modes
-8 Use 8bit address mode for 24c0x...24C16 [default]
-16 Use 16bit address mode for 24c32...24C256
Actions
-r addr[:count]
Read count (1 if omitted) bytes from addr and print them to the standard output
-w addr
Write input (stdin) at address addr of the EEPROM
-h Print this help
Options
-x Set hex output mode
-d Dummy mode, display what *would* have been done
-f Disable warnings and don't ask confirmation
-q Quiet mode
Bus
device Device file representing the I2C bus (eg. /dev/i2c-0)
i2c-addr
I2C bus address of the EEPROM (eg. 0x3A)
EXAMPLES
Read 64 bytes from the EEPROM at address 0x54 on bus 0 starting at address 123 (decimal)
eeprog /dev/i2c-0 0x54 -r 123:64
Print the hex codes of the first 32 bytes read from bus 1 at address 0x22
eeprog /dev/i2c-1 0x51 -x -r 0x22:0x20
Write the current timestamp at address 0x200 of the EEPROM on bus 0 at address 0x33
date | eeprog /dev/i2c-0 0x33 -w 0x200

ACPISMBUS(4) BSD Kernel Interfaces Manual ACPISMBUS(4)NAME
acpismbus -- ACPI SMBus Control Method Interface
SYNOPSIS
acpismbus* at acpi?
iic* at acpismbus?
DESCRIPTION
The acpismbus driver supports instances of the ACPI SMBus Control Method Interface. This enables i2c access to bus segments which might not
otherwise be accessible due to missing "native" driver support. The SMBus Process Call protocol is not supported. All other SMBus protocols
are supported to the extent that the underlying controller supports them.
SEE ALSO acpi(4), iic(4)HISTORY
The acpismbus driver appeared in NetBSD 6.0.
BUGS
Although acpismbus SMBus Alerts can be associated with individual devices, this capability is ignored. When an acpismbus SMBus Alert is gen-
erated, all devices on the i2c bus segment which have registered an interrupt routine are notified.
The SMBus CMI protocol defines a method to provide a list of devices on an i2c bus segment and their addresses. The acpismbus driver makes
no attempt to retrieve or process this device list.
There is currently no way to determine if the i2c controller managed by an instance of the ACPI SMBus CMI can also be accessed using a native
device driver. Therefore, the acpismbus driver should not be enabled by default. If both a native driver and the acpismbus driver attempt
to access the same i2c bus segment, the results are undefined.

I am new to Unix so will really appreciate if someone can guide me on this.
What I want to do is:
Step1: Read binary file - pick first 2 bytes, convert from hex to decimal. Read the next 3 bytes as well.
2 bytes will specify the number of bytes 'n' that I want to read and write... (1 Reply)

Hi All,
For Linux Kernel 2.6.26 :
I am using a I2C bus for command interface from my system when connecting to different devices. I have different I2C frequency requirements from different devices. Can you please suggest me a way to set the I2C frequency based on the device in use at runtime?... (0 Replies)
