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 conguration le 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.
