Really? You make a post just to point out a typo?

:-?
In the funny world of lcd displays, the (0,0) is top left, which is quite different from conventional x,y co-ordinates in the math books. I think this is confusing sometimes.
There are alot of little things like this to get used to with microcontrollers 
... such as counting starting at 0, I made many a mistake when first starting out.. always start counting at 1 and mess things up. 
And I got an LCD that has 131x131 pixels... and it's the same way! Makes for a hassle when you're trying to remember exactly where that pixel would be on the screen.
