Problem with code for a digital thermometer & thermostat model using ds1620 and 89c51
hi,
i made a digital thermometer & thermostat model using ds1620 and 89c51 on proteus. but there is a problem..
only value put in for high temprature limit is working and nothing happens for low temperature limit...means alarm goes on when temperature rises 50°c and nothing happens when temperature goes below 20°c. i have tried a lot but failed to correct the code......can anyone here correct the code:|
thats not a connection problem.. infact high signal is not appearing at pin 6 of ds1620 when temperature goes beloow 20°c.......
problem is some where in the code but cant find where:!:
