Hello, I have used LCD displays several times before, but this LCD is making me unhappy.
It is a 4x20 Blue Backlight LCD that just says QY-2004A, the thing is that it seems to work fine but restarts de PIC18F452, i think this is the problem because with an older LCD (i bought it before) everything works fine.
My concern is because i just bought two of this LCD`s and is strange that both are wrong, maybe someone had this problem before.
By the way i am using the connection as stated in the PicBasic Manual.
