Hi, I hope at least some one on this list would have given a shot with the SSD1308 OLED display. Trying toget "Horizontal Memory Addressing Mode" working.. Does Horizontal Addressing Mode require a start and end like the other two ? According to the datasheet, once Horizontal mode is selected, once can keep writing to the memory pages till the last mapped segment. But somehow it doesn't seem to appear to be working the way I am looking at it or understanding it. ie, for me it is either not working or writing a single line. Maybe my understanding is incorrect. Hope that someone with a better understanding on it can shed a bit more light in there.
