How to put a list into BS2P40

Archiver

Is it possible to put a list into the EEPROM memory of BS2P40, with
BS1 you could do this with the instructions read / write, but i've
been told this doesn't work anymore in the BS2. Are there other way's
to do this with BS2 ? Thanks Hans

Yes it is possible with all BS2 types using DATA statements, and
the commands READ/WRITE. Note that data storage arnges from address
0 upwards and program storage ranges from 2047 downwards.
See also the stamp manual (v2.0) for the commands DATA,READ & WRITE.
For BS2p (24 & 40) there is a further command STORE to select the
program slot for data storage.
Hope this helps

Of course READ and WRITE work with the BS2p family. Somebody was pulling
your leg. In the BS2 family, you use DATA statements instead of EEPROM.
Like this:

Name DATA "Jon Williams", CR, 0
Title DATA "Applications Engineer", CR, 0

You can then print this string using DEBUG with this subroutine:

Print_String:
READ eeAddr, char
IF (char = 0) THEN Print_Exit
DEBUG char
eeAddr = eeAddr + 1
GOTO Print_String

Print_Exit:
RETURN

To point at a string, you can do this:
eeAddr = Name
GOSUB Print_String

Note that by terminating the string with zero, CR [noparse][[/noparse]carriage return] can be
embedded in the DATA statement for printing.

And, on the BS2p family, there is a new command called STORE that tells the
BS2p which program bank you're writing to or reading from. This is very
handy for storing long lists of messages in a separate program bank, leaving
more room for your code.

Remember that you can download the manual at no charge -- that will keep you
from being suckered and frustrated by bad information.
