LDC1312 Reading data after an interrupt.

Hello Frank,

You should use sleep mode for device configuration only. No data is converted once the device is in sleep mode.

Hi Natalia,

The problem was not being able to read the data registers in sleep mode.

I am now reading the CH0 data in active mode and exiting the routine in sleep mode a timer sets the device in active mode every 20 MS for a conversion that triggers an interrupt. this way the device is mostly in sleep mode and not converting.

Thought I could read all the registers in sleep mode, all except data it seems...

Thanks

Frank

Hello Frank,

What you are seeing is correct. You can read any registers besides DATA when the device is in sleep mode. I apologize for inconvinience, but this is how the device is designed. Thus, there is nothing I can do about it at this point. Please, let me know if you have any other questions.

Best Regards,

Hi Natallia,

Not really an inconvenience more of a bit more of a power drain on our solar panel and battery system. We like sleep mode.
I have suggested some updates to the business unit to clarify some things in the data sheet.

Thanks

Frank

Frank,

You could use low power mode in the case when you need to keep on converting @ low current. I am a part of the Business Unit. I sent you a friend request. Please, accept it so I can give you my info and we can discuss further.
