GLCD SED1520

[Mainul]

I was trying to write code for a 12232-2 GLCD  - 122×32 dots LCD Module, built in two SED 1520 LSI controller Using PICBasic Pro.  I can initialize the LCD, can write and display data to any desired line (0~3), but cannot set the column address. I have tried in many different ways, but it always starts from column 0.

I am including the Proteus file, PICBasic code that I was trying to develop and the data sheet for SED 1520, with expectation that someone, who has already written some code for this particular controller, will indicate me what I am doing wrong.

Thanks

margo,

Thanks for the information, though I have no idea about sordfish basic compiler. Well, in the mean time I have found the solution of my problem. When I tried to simulate the code in Proteus, It did not work as it was suppose to, but when I run the same code on a prototype board that I have made for the LCD to run with 16F877A, it works perfectly. It seems to be that something is wrong with the SED1520 Module in Proteus. I have written my font library for this LCD and everything is working perfectly on my board.
