How to configure RG6 for ADC input?
PostPosted: Wed Sep 25, 2019 12:58 pm     Reply with quote

On file 24FJ1024GB606.h there's no RG6 pin in the ADC sector but in the datasheet says that is an analog pin, so how I must to do to configure RG6 and RB15 as analog channels?

Also I can't find in the datasheet a table with channel vs. port pin.

You don't. It is not an ADC analog input on the 24FJ1024GB606.

If you check the pin function tables, for this chip it gives:

C1IND/RP21/ICM1/OCM1A/PMA5/RG6

So the pin gives the RG6 I/O function, PMA5, The comparator 1 input D,
the MCCP1 input capture 1, and the MCCP1 output A. No ADC input.
The only analog function is the comparator input.

On the 610 versions of the chip, it does give AN17. Not on the 606
though.

For your chip it is table3.

On the 610, instead you see:

AN17/C1IND/RP21/ICM1/OCM1A/PMA5/RG6

You are right, I think, but it's a bit tricky, on page 153 of PDF file 30010074e.pdf ANSE have a note.

"ANSE9 is not available on 64-pin devices."

There's no note for ANSG register, that's why I assumed that can be an analog pin.

Yes. The reason there is no note, is the pin does still have an analog
function as the comparator input. RE9 doesn't even exist on the smaller
chips hence the bit is missing for this.
