Please verify IIC address is 0x27 (7 bit) or 8 bit addressing (0x4E)
Attempting to use this display with STMICRO ARM Product STM32F0308- Discovery w/o luck. Have had IIC 4 Segment LED working so pretty sure IIC interface is working. Now this display shows two rows of LCD all on (all on in rows 1,3) and off Rows 2,4. -- This is very constant, (power on) and doesn't change when commands are sent.
Any advise would be greatly appreciated.
I thank you in advance,
