SainSmart IIC/ I2C/TWI Serial 2004 20x4 LCD Module ---

edited December 2014 in Code Issues
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,
