using a bs2 to program a DS1620 to run in stand alone mode

Hello all,
first time asking a question.
I want to program a DS1620 with a Thigh and Tlow so it can run in stand alone mode.

I have succussfully run programs that collect information from the DS1620 and send it to the PC screen via debug plus.

if someone has a sample program i'd be grateful.

i've attached my latest attempt at the program. smilewinkgrin.gif

    Welcome!

    Sample program and advice:
    www.emesys.com/OL2d1620.htm#thermostat

    For example, commenting your code, the following sets the upper threshold at 20 degrees Celsius:

    THi = 20   ' whole degrees Celsius
HIGH RST ' Now activate it again and send the..
SHIFTOUT DQ,CLK,LSBFIRST,[noparse][[/noparse]WHiT, THi*2\9] ' Write the THi setting
' note: WHiT followed by "," not "+"
'          THi * 2 because the THi * 2 has to  be units of 0.5 degC
'           \9 is needed to send all 9 bits
LOW RST ' Done--deactivate.
PAUSE 100
