i2ctool
The
i2ctool
allows for scanning, reading, and writing of the
I2c
bus devices.
To read and write to devices on the
i2c
bus, use the
i2ctool
. The
i2ctool
also scans the
i2c
busses and reports what devices are
found. The scan reads address 0x0 from all the devices in the address range of 0x0 to 0x7f on all
i2c
busses present. The
i2ctool
does
not automatically traverse MUXes along the
i2c
bus. Other tools use this tool to read
i2c
device information and pass the results back
through a named pipe.
Tests
To test, the
i2ctool
has a
configuration
file
that lists all the devices on the busses. The tool runs through the list and tries to reach the
devices. The
i2ctool
reports when a device is not returning data.
