Use Port C pins as digital I/O's?

If no analog inputs are required, is there an easy way to convert the 6 analog inputs to digital pins?

So instead of analog [0:5], Port C would be digital[14:19].

Thx in advance for any help with this!

I think you can just use them as digital pins 14-19 without doing anything special. That is, just call pinMode(), and digitalWrite(), etc. and they should work, although it’s not “officially-supported” so it might break in new releases of the software.

That seems to work. Doh!

Thanks for the help.
