Variable Initialization too large

Probably too much of a pain if you are running the PIC at 5V because of the extra regulator and level shifting required. There are quite a few PICs now that run at 3.3V and these SRAMs would work well with them.

yea agree....but since ill only have to level shift 2 pins.....ill go with it.....

i've decided to go with the external RAM....(as other methods wouldnt work -.-) ....

but i have a question....
how do i access the external RAM? .....by continuously reading/writing the SPI registers....

or is there an easier way of using it juz like how the built in RAm is used

I would take a sanity check at this point to see if you are in over your head. IFF you are only understanding a small part of what is going on in the system you need to start with blinking LEDs. We all did.

which part r u refering to? -.-....

ill try doing some reading up on srams 1st ...

thx anyway

Yes, that's how you would use it. The external RAM should only really be used for large sequential buffers, etc. Variables that need to be read/written, often and randomly, should be hosted in the GPRs on the PIC if at all possible.

thank you kchriste appreciated all da help uve given
