: retval = scanI2Cbus (ar) ¶

: retval = scanI2Cbus (ar, bus) ¶

Scan arduino for devices on the I2C bus.

Inputs

ar - arduino object connected to a arduino board.

bus - bus number to scan I2C devices, when multiple buses are available. If the bus is not specified, it will default to 0.

Outputs

retval - cell array of addresses as strings in format of "0xXX".

Example

# create arduino connection.
ar = arduino();
# scan for devices on the I2C bus
scanI2Cbus (ar)
# output is each detected i2c address as a string
ans =
{
 [1,1] = 0x50
}
