OLEDs / 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...

page 13 of the data sheet says to set reg 0x03 (clock div) to 0x90 to get 90 frames/sec, but the seps525 data sheet says to make it 0x30 for 90 hz. can you update your data sheet? thanx, good product btw!!
