Hello,
I'm trying to put my head around how to write to the CFAG12864 display. I understand the selection of column ranges 1-64 and 65-128. The Column Y-address 0-63, 40-7F hex. The Page x-address B8-BF hex. And display data DB0-7.
What is the Z address? or the Display Start Line address from section '11. Detailed Explanation'
My understanding from the memory/Instruction Data map shown in Fig 1. at the bottom of section 11. is that writing to the display would be as follows,
Select Column CS1 or CS2
Write Y address (40-7F hex)
Write X address (B8-BF hex)
Write Display Data (0-F hex)
Write Display ON (3F hex)
Display data is displayed vertically not horizontally from DB0-DB7 under each Y column address within the defined x page. I'm I out to lunch?
What's Z (Display Start line) ???
Thank you,
