ok, I did switched the inputs on the back of LCD and the character just runs on continuously =/. I suppose that is how I had it originally then. So now I have the TX coming from the PIC (or MAX3232) to TX pin of LCD(pin 3).

Thank you Troy for your quick response! :)

The thing is that it does that even when I am not running the code whatsoever..not even for the first time. Before I even compile, the character there runs across the screen.

I checked the wires and connections they are good. I only have the ground ...

Hi,

I finally got the LCD to communicate with my PIC. I have it the PIC connected to a MAX3232 chip which converts TTL signals to RS232 and from there I have it connected to the serial interface of the LCD. I've been working on this issue for almost a week now and I still can't figure out why the ...

A max3232 should've solved the problem..it takes the TTL inputs from the PIC and ouputs RS232 signals to a DB9 connector..and to LCD.

No need to go through that soldering stuff.

Troy, much thanks

I added a line of code to shut off flow control and that did it..for the most part. Now I can print to screen! XD ...except that..when i turn off the LCD and turn it back on it prints weird character non stop ..another thing to tackle but finally got something going. Much thanks!!

Thanks Troy for looking over my problem I really appreciate it! :)

Thanks for letting me know about the flow control I will make those changes and let you know of what happened. I have my PIC connected to a MAX3232 which converts TTL singnals to common RS-232 and from there I have it connected to ...

Hi! :)

I've been trying to make my LCD (LK204-25) clear it's screen. I'm using a PIC (PIC24HJ12GP201) to connect to my LCD. I think I read through the forum that PICs output as TTL so the LCD would have to have the jumpers soldered for TTL is this correct? I've changed to TTL and just as trying ...
