Successfully got the 16x2 and 20x4 character lcds working with the I2C backpack.
Yes you do need to be careful in setting lcd.begin(16,2) or lcd.begin(20,4) else, well, spaghetti display!
Now looking at configuring multiple Lcds on the I2C bus.
What is the limiting number of Lcds that can be supported - the tutorial says 7 - but where does this limit of 7 come from?
Is there example code and method to configure multiple Lcds?
