scanI2CBus
Scan I2C bus on Arduino hardware for device address
Syntax
Description
Examples
Scan I2C Bus 1 on Arduino Hardware
Create a connection to an Arduino Due and scan the specified bus number. You can specify bus 1 only if you are using Arduino Due boards.
a = arduino('COM5','Due','Libraries','I2C'); scanI2CBus(a,1)
ans = 1×1 cell array
{'0x48'}
Input Arguments
a
— Arduino hardware connection
object
Arduino hardware connection created using arduino
,
specified as an object.
bus
— I2C bus number
0 (default) | numeric
I2C bus number specified as a number.
Output Arguments
addr
— I2C bus address
character vector
I2C bus address returned as a character vector or a cell array of character vectors.
Note
For more details on creating the I2C device
object using address returned by
the scanI2CBus
function on Bus 1 on the
Arduino Due board, ArduinoBLE, and, ArduinoBLE Sense, see Board Specific Issues, .
