Hey im trying to interface a glcd with 89c51 mic. But when i creat a circuit and simulated it in proteus with a hex file im getting an error "proteus non- existent pin invert specified by invert LCD U1 LCD U2 ". And nothing is displayed.
It seems proteus is trying to include another IC "U2" in simulation. But it does not exist in the file, right?? Have you clicked in the link "LCD U1" & "LCD U2" in source column of error message box?? Try redrawing the circuit from start..
