    the project is event timer control system using rf gates


    its hard to write each of the blocks here without describing in full all the software components and their functions

    but as an overview the hardware has

    2 x spi buses , rf devices sd card , 32m flash
    software spi for rtc ( to be changed to IC2 on next update)

    usb/ serial for updates/ terminal services / other support hardware / remote displays

    sound / horn control modual
    4x 4 matrix keyboard
    option 1 - 240-x 64 GLCD
    option 2 - 240x128 GLCD with touch screen ( to be done yet)
    spi 32meg flash - holds fonts / banners . terminal strings/ event dephaplts , time records of events , system controls / update temp bootcode


    the hardware is simple stuff really but coding wise it takes a space for all the options anf fuctions for the rf compontes and thier many options , and trying to make t work well woth only 64mhz is also a challenge.

    without access to most of varables when using the hardware from the other cpu , alot duplication is needed as well addtional interface code from what i am thinking ,

    i guess thats price you pay for the 128k limit and project thats getting to big

    it real shame that pbp cant make use of the larger pics , even if it were just the code space

    Is it possible to have two versions of the board, one for each LCD?

    That would make for an easy "split line", and have common code for most of the logic (easier to maintain).

    You keep talking about code duplication, Maybe you should look at turning some of it into subroutines and save some space?
