OneWire Temperature Display
Re: OneWire Temperature Display
Program looks ok. Check your hardware if you connected properly. What value of pullup resistor are you using? Have you got +5V to DQ pin?
Re: OneWire Temperature Display
I got 3.27 V to DQ pin My development board is Mikroelektronica LV-24-33 on board Pull up resistors is 10K
Then I gave externally +5V to Ds1820 Vdd pin but same results.
Thanks

Re: OneWire Temperature Display
Hello,
please, follow these links:
DS18S20 datasheet: http://datasheets.maxim-ic.com/en/ds/DS18S20.pdf
DS18B20 datasheet: http://datasheets.maxim-ic.com/en/ds/DS18B20.pdf
You can make a comparison between the two temperature sensors.
Best regards,

DS1820 and DS18S20 are the same sensor, which have a 9-bit resolution while DS18B20 has adjustable resolution from 9 to 12-bit.

Re: OneWire Temperature Display
one question , which line determines temperature refresh interval?
Thanks
Thanks
