I am trying to figure out what changed with V5. If I use a GrovePi+, the V2 works flawlessly, both RGB and text, and the V5 shows text but the background colour doesn't work properly. By that I mean I get the wrong colours (mostly various shades of white) and it flashes like crazy. Yes, V5 has had an I2C address change and I adjusted the python code accordingly. I have a friend with a V4, and they report 0x62 and 0x70, no 0x3e for them. Help? |

Hello I've got the same problem and I solves the issue
In the Cpp file the "_initialized = 1;" line in "void rgb_lcd::begin" function is placed at the end of the function.
So all previous "command" function don't work because they test "_initialized" before doing the job.
To Fix place the "_initialized = 1;" line at the begining of the function
i.e. After "_wire->begin();" line 75
and all become OK
This is a clue that the lib was provided without Testing it (:-(
