haha steve , well i hate not having enough space . and 128k on the chip is waisted by the many menus, specific fonts / graphic symbols in the program space .

I am not sure if i can use any of it for real program space , i dont think its possible.

i was close to puting on 32MBit storage as the cost differance was about 8c per chip more , but i think 8mbit storage should be enough to hold the menus / and special fonts / banners i need for the moment


I am currently using a software spi , and i am hoping it will be quick enough to get the data off in no noticeble lag time

ill still need to use the SD card for data loging so the file is easly moved from the device to the computer for further work. so that has to still be done

i get these chips friday and will need to install a 5v tollerant buffer IC to the CE pin as the cpu runs at 5v . not sure if a resistor in line and pullup on ce pin to the 3v3 would be a good idea for this chip ?

to get this chip running i was hoping to find a common command set structure in PBP for the flash to allow for read /write / protect / access to mem block examples

any links you got for that ?
.

from what i can see i should not need the hardware write protect connected to the cpu at this point , or the hold ,

as i emailed you yesterday i was feeling very unsure about haveing menu data /stored config parmenters /etc sitting on a Sd card that could be removed - it just invites a problem
