Comment #3 on issue 171 by robhamerling: ADC group change for several
18Fxxk22 PICs
http://code.google.com/p/jallib/issues/detail?id=171
While checking for other changes/errors/omissions related to ADC I
encountered something 'suspicious'. Some PICs use ANCONx registers to
control the analog/digital setting of pins. Up till now I found only one
type of setting:
for analog bit = 0, for digital bit = 1.
However in the datasheet of the 18f87K22 family (39960D page 358) I read
the reverse: for analog bit=1, for digital bit=0. When that is correct the
device files would have to be revised on this point (enable_digital_io),
but probably also the ADC libraries need revision.
BTW. While searching the Microchip forums I found an discussion about
problems with ADC and the 18f87k22 and mcc18. Maybe this is the same issue.
It seems this needs further investigation!
