Hey,
I'm wondering is there different analog and digital grounds for the PIC18?
The device does have two grounding pins but they are both labeled the same (VSS). Also the data sheet refers to VSS in discussions and specifications on the ADC module (as well as digital parts). On measuring the resistance between the two ground pins I'm getting abut 2 Ohm implying the are indeed the same net.
I dont think there is too much point in extending my AGND to the PIC if it is wired to DGND internally, perhapps this could even be bad for my ground isolation...
any insights??
Thanks
