Hi 

Thanks many lots help to us.

Now We have question for about this,

I want to know about this one , we confuse which is Correct or best?

Data sheet Page 17 about  " Automatic VS Manual Control"

  ADC_Control [ ADC ON ]  set to  "0",  this mean is Stable time keep for 500usec

 when AD converter strated by Automatic.  recomnded  "Automatic Mode".

But

Data sheet 18   about  " ADC Application Notes"

 If  AD Conveter started  at  ADC_ON  = 0,  become to "look up and stop working"

and need  "Reset"  .

We confuse about these Page17, 18 comment, which is correct ??

Thanks and Regard

Jasper

    Jasper,

     

    Locks up if you set ADC_ON=0 and start converting CONVERT[CONV]=1

    If you just have ADC_ON=0 with CONVERT[CONV]=0 then no lock up.

    If you have ADC_ON=0 with CONVERT[CONV]=1 then it will lock up.

     

    You do these steps like in datasheet.

    1. Set to 6uS.

    2. ADC_ON=1

    3. CONVERT[CONV]=1.

     

    You can set ADC_ON=0 to save power.

    Does it make sense?
