BS1 extra EEPROM ?

Sasha

Hie to everybody,
I need to add an extra EEPROM to BS1·to store some values (PINS directives) like this:
A:
PINS = %01111100
PINS = %01111110
PINS = %00110011
PINS = %00110011
PINS = %00110011
PINS = %01111110
PINS = %01111100
PINS = %00000000

B:
....
....
C:
....
etc.....

And after use this values in the BS1·like this:

main:
use value·"A" from external EEPROM
PAUSE 10
use value·"B" from external EEPROM
GOTO main

So, can you tell me what EEPROM to choose for external storage, circuit between BS1 and EEPROM and some simply source to learn and figured how it works
·Thank’s

If you’re going to store patterns in external EEPROM you won’t be storing them like that. You will simply store the actual patterns and then write a routine which accesses each pattern and sends it out to the I/O port. Note that since there are no built-in commands for accessing an EEPROM, you may need to write some yourself or look for some example code which demonstrates this. Take care.
