External memory interface

Andrew Messier

Hello,

I'm using an STR710fz2 ARM7 processor, and I need to interface with the external memory bus. The datasheet discusses timing and wait states, but I haven't seen any software application examples that actually show how to implement this interface. Does anyone have any example code?

Thanks,
Andy

    Yes, if you have external memory connected to bank 0 (address lines, data line, CS0 and RD/WR) and it works with 3 wait states or less.

    You can also create a region of memory called something like EXT0 that the compiler and linker know of and have variables assigned to this region, possibly even all of your variables.
