I just got the I2C multiplexer and hooked it to Arduino Uno. Default address 0X70
I copied the * TCA9548 I2CScanner.ino -- I2C bus scanner for Arduino sketch to the IDE. When I upload and open serial port the only message I get is 'TCAScanner ready!'
The script does not loop to get the 8 addresses. Currently I have not hooked any devices to the multiplexer.
I have the SCL/SDA/Vin(5v) and gnd connected. Nothing else is connected.
What am I doing wrong?
