Hmm, I don't quite get it as well...
The I2C_LCD option uses a PCF8574 interface. This indeed translates the HD44780 pinout to an I2C pinout.
I couldn't find any more on the manufacturers site or the github code regarding more differences.
There is one potential cause in the code.
Can you try "USE_I2C_LCD = 16x2" instead of "USE_I2C_LCD = True" ?

Hey, yeah, I've tried that too, no change.

Oh well, thanks a lot guys, if this doesn't work I will just go get myself Pirate Audio Line out and will take apart this screen and use it in some Arduino project.
really wanted this to work, bit seems to be something wrong.

But will install a clean image, and try again one more time. Will let you know if it changes anything.
