I am trying to fed a 240x64px graphical display with my msp430x149. That needs an array of 15360bit (boolean information) about a shown pixel or not. So I will need at minimum 1920byte of RAM to store that array in the µc. We only have 2k RAM in our MSP. So it is afaik impossible to manage the display-data at this way.
what kind of controller does your display have? usualy does the LCD controller store the image. so you dont need to keep it once again in the mcu.
The other idea is to calculate all graphs or singns while sending every bit to the graphic-controller. But that will not be very easy and also not very fast.
well, you have to calculate your graphics anyway. you have to transmit the data to the display anyway. sure you're faster transmitting images of 8 pixels width (or height depending on the LCD controller) but then how many display updates do you need to do per second ;-)
there is a gfx_lcd in the examples (see mspgcc CVS or the examples folder in the windows installer) that one is for a T6963 controller, maybe it fits for your display too...
