https://wiki.onion.io/Tutorials/Python-I2C-LCD-Display works fine with my 2X 16 but would only populate 3 lines of a 4X20. 4th line just not happening

@andrew-mackay

Trying the tutorial with an Omega2+, but the LCD does not show up in i2cdetect and the sample code from the tutorial is not generating any errors message when it runs.

Did you make any changes to any steps in the tutorial? (Double checked wiring, connections, and screen contrast).

Thanks in advance.
