I2CSCAN(8)                BSD System Manager's Manual               I2CSCAN(8)

NAME
     i2cscan -- scan an IIC bus for devices

SYNOPSIS
     i2cscan [-r] i2cdev

DESCRIPTION
     The i2cscan utility scans the IIC bus (iic(4)) specified by i2cdev to
     determine which addresses respond.

     Available options:

     -r      scan using 1 byte reads instead of quick writes.

     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.

EXIT STATUS
     The i2cscan utility exits 0 on success, and >0 if an error occurs.
