It you're using a module with controller, try a google on the
controller chip part number for code examples to do your basic
graphics functions. Eg. (Toshiba) T6963, SED1520, KS(mumble) . There
are only a few common controller types for the graphic modules. Some
ARM microprocessor (almost microcontrollers, just missing the code
memory) chips have *built-in* controllers that work with displays that
have just drivers and no controller. A suitably programmed FPGA can
also be used with that kind of display. You have to spit out data
continuously at a fairly high rate to that kind of display, so it's
unlikely to be very attractive to try and do it in firmware.
