HDC Configuration of HDC1000 EVM GUI

Other Parts Discussed in Thread: HDC1000

Dear All

I'm reviewing the GUI of HDC1000 EVM.

I found the bellow problem.

If Software Reset is selected in HDC Configuration, Battery Status is changed "Voltage > 2.8V" to "Voltage < 2.8V".

I can not understand why Battery Status is changed.

I think that the register value of HDC Configuration has to be changed "0x1000" to "0x9000".

I want to know why.

Please refer to the bellow pictures.

- When Software Reset is selected

- When Normal Operation is selected

Thanks.

    Hi Chung,

    when you issue a software reset, the behaviour of the HDC1000 is very similar to the startup.

    The info on the battery status needs to be re-evaluated by the HDC1000 and it happens only after a request of measurement of RH or Temp.

    See the section of the DS related to the Voltage supply monitor,

    regards,

    Domenico
