Hi Flotul,

What is the baud rate of the Serial Module on the LCD? Most of the ones I have seen are either 2400 or 9600. With the internal clock at 4mhz the best you can hope for is 2400 because of the not so stable clock freq. I use a Seetron Serial LCD @2400 and it works fine. I have some other Serial LCD's that I am trying that I got from Wulfden.org but he has a different command structure that uses ? in fron of the command letter. I get data displayed but it's all running together. Always the time factor.

Try putting a crystal or resonator on your PIC and see if theat doesn't help.

HTH,
