SYNOPSIS

xcmddc [ -l [-v] ] xcmddc [ -d POSITIONAL_NUMBER [--force-output] [--identify] ] xcmddc [ --i2c NODE_NAME [--force-output] [--identify] ] xcmddc [-h]

DESCRIPTION

The xcmddc tool fetches a monitors EDID data block over a i2c communication channel.

OPTIONS

-l list devices. Only devices which provide a EDID data block and the EDID’s header is valid will be counted.

-v show each device by its node name.

-d=POSITIONAL_NUMBER , -d POSITIONAL_NUMBER
  position in device list. The numbering of monitors starts with zero for the first device. To get the number of all available devices use "xcmddc -l". The EDID data block is dumped to stdout.

--force-output switch EDID header verificatcationn off.

--identify dump the error code as integer to stdout.

--i2c=NODE_NAME , --i2c NODE_NAME
  select the i2c device node file. The EDID data block is dumped to stdout. The --i2c option is much faster than the -d option. This is because of much fewer timeouts reuired for counting the valid i2c device with the -d option.

--force-output switch EDID header verification off.

--identify dump the error code as integer to stdout.

GENERAL OPTIONS

-v, --verbose
  increase verbosity

EXAMPLES

Count available i2c->monitor devices:
  xcmddc -l
List available i2c->monitor devices by name:
  xcmddc -lv
Dump EDID from first i2c node:
  xcmddc -d 0
Dump EDID by i2c device name:
  xcmddc --i2c /dev/i2c-5
