[Shailesh Bakshi]

Dear Team,

I am try to customize the  some of the parameter of HTS221 temperature and humidity sensor used in thingy52 board, However if I change any of the parameter then I am not able any output of the temperature sensor in thingy aap

Hi,

However if I change any of the parameter

What parameters did you change ?

Thanks for reply!,

By default  sensor is running with following configuration:

AV_CONF(10h) : 0x1B

CTRL_REG1(20h) : 00

I want use (HTS221) sensor with following configuration:

AV_CONF (10h) = 0x1F

CTRL_REG1 (20h) = 0x87

It might be the CTRL_REG1 that is causing the issue.

If you only change AV_CONF to 1F, and keep CTRL_REG1 at 00, does it work then ?

[Shailesh Bakshi]

Yes it is working

Ok. The Thingy:52 humidity driver is doing one-shot readings, see this link. So it looks like your configuration of the CTRL_REG1 register is not compatible with the way the Thingy:52 humidity driver is designed to work.
