SV: [basicstamps] DS2406/2407

Archiver

Greetings!

Works GREAT!
(After I changed it from 'Skip ROM' to 'Match ROM' and added ROM ID's so
that I can control more than one :-)

Trygve-

The following works for me to toggle PIO-B:

sram VAR BYTE
crc VAR BYTE
i VAR BYTE

again:
OWOUT 0,1,[noparse][[/noparse]$CC,$AA,$07,$00] ' cmd: read sram
OWIN 0,0,[noparse][[/noparse]sram]
DEBUG CR, HEX2 sram
OWOUT 0,1,[noparse][[/noparse]$CC,$55,$07,$00,sram ^ $40]
OWIN 0,0,[noparse][[/noparse]crc]
DEBUG CR,HEX2 crc
OWOUT 0,0,[noparse][[/noparse]$FF] ' serves as programming "pulse"
OWIN 0,0,[noparse][[/noparse]i] ' no apparent significance
PAUSE 5000
GOTO again


The above code was written per the algorithm depicted in the
datasheet's Figure 7, "Memory Function Flow Chart".
