readme.md Code to read and write EDID chips over I2C 2023-04-02 17:29:13 +02:00

Read and Write EDID

Read and write EDID data over an I2C bus.

Usage

Load the Linux kernel module:

modprobe i2c-dev

Adapt the I2C bus device /dev/i2c-4 in the examples below to whatever matches your hardware setup.

Note: Be very careful to write to the correct bus! Failing to do so may seriously damage your hardware!

To read an EDID, run (as root):

./edidread -d /dev/i2c-4 > edid.bin

To write an EDID, run (as root):

./edidwrite -d /dev/i2c-4 < edid.bin

Note: The edidread tool writes binary data to stdout which is potentially dangerous. Redirect the output into a file or pipe.
