Yes it is. The controller inside the LCD refrshes the display with data from the DDRAM...so from an interface point of view you treat the display as RAM. Write a byte to an address, which specifies its location on the screen (for 128x64 usually aranged by columns and rows) and it will display the data. Plenty of example code on the net for both assembly and C....even basic...and its not too difficult to see what the code is doing so you can translate it from one language to another.
