Thanks Guys
The the circuit does use the R/W, RS & E1 Pins
So just to confirm, the "remote" LCD should be "Faster" than the "main" LCD and the "remote" R/W should be grounded?
This is because the faster "Remote" LCD will process the data before the "main" LCD send a confirmation on the R/W pin to continue? Sorry, I'm a newbie on PICs nevermind LCDs.... LOL
If my understanding is correct, then would it not be better to make the "main" LCD faster and ground the R/W and rather use the slower remote LCD trigger the R/W, therefore making it safer as if there is any issues due to capacitance of long cabling the remote would always be last to process and trigger, and knowing the "main" would have finnished already? Hope that makes sense, but of cause it could only make sence if my above statement is true........
