If I create an array the same size as the display and create my images in that (I know I would end up with 8 pixel columns in each location if I used a char array) then send this to the display. Things I am not sure about - drawing the graphics in the array (must be possible, just not sure where to start) and secondly, how to update (send to LCD) only the bits of the display which have changed (unless I have a second array and compare??)

Any idea on the location of get/set pixel routines??
