Hi everyone,
does anyone have any experience in using the at91sam7se (or at91sam9 with EBI)
static memory controller to hook-up to a 68 or 80 series interface?
In the datasheet, it is said that "The SMC can be configured to work with an
external LCD controller by setting the ACSS bit in the SMC_CSR
registers.....".
The problem is, in our case the display (a Densitron OLED display module with a
SEPS525 controller) has a shared data/address bus. In the at91sam7se data sheet,
this fact is overlooked as both data and address lines are shown in the timing
diagrams. Do I need external logic to multiplex these lines then? The datasheet
is pretty vague about it.
Before I commit myself head over heels into a scarcely documented set-up, it
would be of great value if someone could confirm Atmel's claim.
Thanks,
Ewout
