Thanks Eric,

I read the document mentioned in the config files just now
and I wish I would have read that before bothering everybody.

I was sitting here pulling my hair out wondering where
I was going to get enough ios,what with all the encoder counters and pwms.

You confirmed what I thought the document
said.I feel much better now.

Thanks for your time

Terry
