Hi, i tried to use IAR example about LCD for use my display hd44780.

I connected 6 pin (RS,E,DB4,DB5,DB6,DB7) for use it on 4bit configuration (i'm sure that the connection is good cause i used that on my old arduino board).

I only see first line of black simple, nothing else.

Can someone help me with that code or link some other library that work good on stm32vldiscovery.

Thx
