    Thank you for your response... I've looked at the two links that you posted and I understand now how to write the data to the CGRAM registers. How though, do I tell the LCD a specific location to display the created character? I've attached a jpeg of how I want to display these 5x7s. As you can see, the top left of the I starts in the 3rd character location of the first line. So I need to figure out first how to write that to CGRAM and then how to display it in that particular location. I'm hoping that I can write one location of CGRAM, display it, then overrite that location to display something different in a different location. Any thoughts? If anyone has an idea of how I can get my LCD to properly display what I have attached, I would greatly appreciate any of your help with this.

    Thanks again in advance.
