I am sorry for a late reply. I want to thank both of you, for all your help and advices. I will follow what you two have said.
I was very busy for the last two days. After work, I was trying to figure out, why I was only able to access two lines of my LCD. I feel somewhat silly now, it was a really basic error that was not a part of my LCD controller, but the one that was telling this controller what to do. I'm glad I got that solved now.
Thanks again! :thumbsup:
