Declaring memory space in external memory

HenkvW over 12 years ago

Hi,

I'm using the STM32F103ZD microcontroller. This uC is residing on some control board and is physically connected by it's address bus and data bus to an external 1M*16 SRAM memory chip.

I would like to declare a static buffer (which is larger than the onboard uC ram memory) in this external memory. Lets assume the external memory access starts at address 0x8000 0000.

My questions is: is it possible to declare such a static 'external' buffer in the source code, and if so, how should I declare this buffer?

Thanks in advance,

Henk
