    Hello everyone, this is my first post here. I am looking to start a new project with a Graphic LCD display. I want to use a serial connection to free up pins on my PIC and possibly remotely mount the GLCD, and running 3-4 line can be done with a phone cord. My problem is cost for a serial module. So i thought i might try to make my own. So i looked on ebay for a display and i found one that is pretty cheap..$ 14.00 Blue BL/Whit letters.

    So i looked at the data sheet here:

    Pin 15 is for SERIAL/PARALLEL SELECTION ... So if i am right, i can select serial and i dont need D0-D7 pins connected to my PIC, they are 8-bit parallel line. I can use a serial connection or I2C. This would greatly lower the number of pins need from my PIC to run the GLCD....also i am using Proton PICBasic.

    So my question is how to interface the GLCD with serial signal form my PIC? How do i connect the pic to the GLCD??

    Thank You!! :D

    Try this link:
    That's the 2nd part. Click on the "2-Wire LCD Interface" link to get the background.

    You will sacrifice a great deal of speed by using a serial interface. It will also cost you in terms of uC memory due to the additional code required.
