    I just started with picaxe and so far had no problems, got a good grip on i/o and adc and decided to move on and interface to an lcd. I can get the lcd working (tho i am using the code in their manual as a starting point) but i am having problems to write at specific locations of the lcd. I played with 16x2 and 20x4 but can't figure out how to print to it apart of starting at the beginning of the matrix. I can get the all string to scroll (again i used the demo code with slight changes). Obviously i am missing something and although i found resources on the web i can't figure out what i am doing wrong.
    My lcd is parallel connected to the picaxe and is set to 4bit. Also is any difference between 16x2 and 20x4? The 20x4 print only on lines 1 and 3 while 16x2 print on both lines?
