Poblem with tps65811 ADC (repost in correct forum)


I'm using tps65811 to control power on my Atmega128RFA1 based design.

It works fine except  provideing power to the system and managing battery charging.

Howevr i'm stuck The problem is that my adc readings are always 0 on all channles

II wonder if somebody can have post a code sample to be sure that i'm not doing something wrong.


P.S. My.ti  rgeistration form is seriously screwed, shows text in chinese.  I can't  register my own account and have to use a college's account

  • Hi Thierry, 

    As for the power rails not coming up I would suggest you look into the state diagram and sequencing in the datasheet on pages 34 - 39. 

    for the ADCs, I would recommend to you the state machine in the datasheet on page 76 and read through pages 67-76. 

    Follow these state machines and see if that matches what you are doing.
