Forgot to enter my script.

/* Jim Moroz's attempt to combine mux and AHT examples. program TCA and AHT V6.ino

copied and pasted from the library examples code from:

  1. BasicUaageini from the TCA9548A

  2. adafruit_aht10_testlib from the Adafruit AHT10

My compile error:

I2CMux.begin(Wire); // Wire instance is passed to the library

I2CMux.closeAll(); // Set a base state which we know (also the default state on power on)
