Hi -
Does anyone have experience driving a 4x40 parallel LCD with this backpack? I understand that 4x40 units have two enable pins. It is not clear reading the specification of the i2c / SPI if the backpack will work.
Thank you for your advice.

Can you recommend a 4x40 display that works with the unit?
