12bit ADC in dsPIC?

[beambase]

Iam using the dsPIC version of FC and doing a project on a 30F6012A. The 30F6012A has a 12 bit resoltion ADC but the standard ADC component will only use 10 bits. Is there a way to get the ADC component to work with all 12 bits?

Hi beambase,
If you use ReadAsInt, then if 10 bit then Maximum value would be 2y(10)-1 = 1023.
If 12 bit then maximum value should be 2y(12)-1=4095
Which is what I get in the simulation.

Not tried on hardware yet.

For people using PIC, there are also some of PIC devices that use 12 bit.
