I have one of these LCD shields connected to an Uno R3, and I wanted to display strings on the LCD using Matlab.
At first, I used Arduino IDE to test my soldering and ran the Example code for the Adafruit RGB Character LCD Shield and Library - it worked well, but my later work on Matlab wasn't that smooth.
I installed Arduino Support from MATLAB, and followed the steps here, but wasn't able to see any strings/backlight appearing on the LCD, nor were there errors.
I was wondering what I might have done wrong, and what I should do in order to achieve this. Attached is a picture of the LCD shield on top of the Uno R3.
Many thanks for the advice and help in advance.
