Hello Vishnu,

Thank you very much for your reply. From what i can see the code is pretty much the same so it may be a hardware issue. Again thank you very much for the help.

Hello,

By using TWI scanner example I am able to find the address of HDC2010 as 0x40. Attached are the files I implemented and its working fine. I took reference from TI code and there are some other sample exampled code. I modified to Noridc and working fine.

devzone.nordicsemi.com/.../hdc2010_5F00_operations.c devzone.nordicsemi.com/.../hdc2010_5F00_operations.h

Thanks & Regards

Vishnu Beema

I apologise for that. I completely forgot to set the SCL and SDA pins to the ones i am using. After setting that the accelerometer is discovered on the correct address but still no HDC2010.

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.

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.

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.

Hi,

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