i2cscan
— scan an
IIC bus for devices
i2cscan |
[-r ] i2cdev |
The i2cscan
utility scans the
Inter-Integrated Circuit bus
(iic(4)) specified by
i2cdev to determine which addresses respond.
i2cdev can be specified with or without the /dev prefix. For example, /dev/iic0 or iic0.
Available options:
-r
WARNING: Using this utility can access some devices in such a manner as to leave them in an unstable or unusable state. It can also lock up the entire iic(4) bus. Don't use this utility unless you know what you're doing and can accept all sorts of unforeseen consequences.
The i2cscan
utility exits 0 on
success, and >0 if an error occurs.
Scan the first IIC bus found on the system for devices:
i2cscan /dev/iic0
