MPXA4115A picbasic code

[mark_s]

Thanks bitmaniac,

I have read Alain's explanation about "oversampling" and "rolling mean value" in a previous post but I'm still not clear why it is necessary to declare a DEFINE to do so.

I think, I don't understand what the DEFINE does.

Any clue for me?

Hello,
You are correct you should set the pic to 10 bits:
DEFINE ADC_BITS 10

If you study Darrel's example in the above link, bottom of the article.
You set your oversampling resolution in this line:


ADbits = 12 ; set to 12-bit resolution
