Hi both,
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" ?
Regards, Hans
