interfacing DS18B20 digital temperature sensor to nRF52810

[srinivasa m]

Hi everyone,

I have used the this code (https://github.com/sigurdnev/Nordic-DS18B20) to interface ds18b20 digital temperature sensor to nRF52810.

it is giving the temperature value as -0.0625 constantly.

same code i checked with nRF52832, it is giving correctly.

i have used 10k pullup.

could any one help me on this ds18b20 interface to nRF52810 temperature reading.

Hi. You should use resistor 4.7k or less

thanks for the reply

I have checked with  2.7k resistor, with that resistor also same value(-0.0625) getting

I have one doubt that is there any code compatibility issue?

I  have used S112 soft device

-0.0625°C is initial value of DS18B20. It seems like there is no delay (700ms min) after reset DS18B20. Try to use another driver. And what about voltage? Is it 3.3V?

can you please suggest me any working driver for nrf52810

supply voltage is 3.3v only

I have solved the issue and now I can able to read the data properly

thanks for the support
