Sample code integrated with HDC2010

[beemavishnu]

Hello,

I am using nRF52832, SDK_15.3.0, S132 SoftDevice and Segger for flashing the image.

Is there any sample code integrated with HDC2010 Temperature & Humidity sensor over TWI for reference.

I want to integrate into ble_app_blinky.

Thanks & Regards

Hi,

Unfortunately we don't have any sample code for this in our SDK

Hello Vishnu,

I am trying to get my HDC2010 working with the nordic chip but i keep getting a NACK every time i try to talk to it. It returns a NACK before i send any of the register addresses or the data which makes me think that its something to do with the HDC address. From my understanding the address of the sensor is 0x40 but i may be mistaken. Also do you also include the write/read bit in the address or do you send the address as a 7-bit number?

Thanks.

The easiest way to answer this is to use the TWI Scanner example - it will tell you the address as used by the Nordic routines.

Thank you very much for the reply, although it doesn't seem to be working correctly. Its not finding any devices on the TWI although I have both the HDC2010 and an LIS2 on that and the accelerometer has been tested and works fine. I've enabled the TWIM0 instance in the sdk_config of the project because those were not enabled but i still cant seem to get any of the sensors showing up.
