I gotten everything but the READ_DISPLAY_DATA command to work properly. Is there a code snippet that shows this 'dummy read' that needs to be done? I have done a WRITE_DISPLAY_DATA (set to 0xff) (which turns an entire column on), and reset the Y address back one, and I cannot get the proper read result (always reads 00, instead of FF). Under READ_DISPLAY, the 'refer to the explanation of output register in "Function of each Block"' is a mystery in the 'datasheet'.
