I try to handle a lcd from 138 decoder.
E=Y6 decoder (address 6000h)
Rs=A0
R/W =Gnd
The lcd module aparently initilize, but don´t write nothing.

The A0 signal fall before that E could be the problem??
With the port 1, i try to mantain signal Rs (Now Rs=P1.7) in this form the signal Rs is assert before and after the Enable signal, but NOTHING!!

What happen??
I hope any good response.
Thanks, excuse my english!!
