Adpd1080 register setup vs adpd105

Hi there, 

we are currently working on a portable health monitoring system, and for our newer version we changed the ADPD105  to the ADPD1080. I tried to use the same register set up what we used previously for the 105 but is does not work, unfortunatelly. The led just blink one times when we start the program, but after that it's stop working. I read the documentation several times but i could not discover the differences beetween the two IC's main registers. 

What are the main differences beetween the two chip, are there any register setups what we sould change compare to the adpd105? 

Thank you for your help,

Marcell Berkes

  • Hello Marcell,

    The register setting looked fine. Please check your setup for a few questions below:

    1. You are using the ADPD1080 with remote trigger from the GPIO1 line. Is that hardware connection verified?  If this is different hardware than was used on 105 it could be an issue.

    2. Does the part work when triggered internally?

    3. Can you put a scope on the interrupt line?  A) does an interrupt get generated?  And B) if so, does it get cleared?   Does any data get read?

    Your description that “The led just blink one times when we start the program, but after that it's stop working" does suggest a triggering issue.

    Best regards,
