Source code to get DS18B20 temperature feedback in nrf51822

[chianglin]

Hi,

I am using nrf51822 to get DS18B20's temperature data, but I am fail to do it.

Would you please give me an sample C source code which can get temperature data from DS18B20?

Thank you,

Hi Ives,

• Before adding new features, can you confirm that you are actually getting out the correct values from your temperature sensor?
• Could you also provide schematics on how your DS18b20 circuit is as well? (do you use a pull-up

I got this when testing your application:

Make sure that your circuit is like:

Hi Martin,

My DS18B20 hardware circuit is the same as you.

Let me check if there have any problem of hardware circuit, and then discuss with you.

Thank you for your assistance.
