seps525 col/row line troubles
« on: August 15, 2018, 09:37:16 PM »
I have the 160x128 oled module that I have been trying to get working for the last or year or so, I'm trying to dispay three 20x20 images, but they only display correctly when the row and column start at '0' (zero)
when I set the colmn to start at 0-19 and row 0-19 the image is fine, when I change the columns, for example, to 20-39, the image gets scrambled, the more I move the colums to the right or increment, the worse the image...

as you can see , the more I move the  image toward column 159 the worse it gets... the image always starts at 0,0 then finshes at the programed column
