20x4 LCD only displays 16x2 output?? (I2C) - s1100 - 04-11-24 Hardware: 20x4 LCD w/ I2C backpack Only displays 2 lines in 16x2 mode... the other 2 lines are blank Config info: "USE_I2C_LCD = True" --> displays 16x2 "USE_I2C_LCD = 20x4" --> no output "USE_I2C_LCD = 16x2" --> no output ("USE_HD44780_16x2_LCD = False" in all cases) Anything else to try?  Thanks for input/ideas RE: 20x4 LCD only displays 16x2 output??
