1000 Threads found on edaboard.com: Pic 2x16 Lcd
I think, your RS pin from lcd1 is connected to a floating pin on pic (RE0) and your code is putting RB0 to ground.
are you supposed to connect RS to RB0 ?
I don't know basic pro, I use C. Make sure you're initialising lcd properly in your code (with specified minimum delays).
I've simulated same lcd with 8051 and (...)

No, the lcd needs to be initialized by the micro, through some commands.
Are you running anything on the pic? Perhaps the code is not right, or the timing, or... there are a few things that can go wrong.

This is an 2x16 lcd COG. It uses a 24 pin header.

You have to use A/D converter of pic and implement a conversion table on code based on sensor chart.
for displaying on the lcd screen, i think you have an in-built controller on lcd.
