First, the PCON register is not supported in gpsim. The good news is I just added it and will try to get a 0.20.10 out within 24hrs with the change. gpsim doesn't fully simulate the reset conditions, so the POR and BOR bits will essentially be general purpose bits. (Upon startup, both bits will be cleared. After a reset, they'll also [improperly] be cleared). I'm going to try to get an RPM built to simplify the install problems everyone is having with gpsim.

This is great !!! such only say and you make the changes, I hope some day learn more of C, C++, and can adding me contribution to Gnupic. > I'm going to try to get an RPM built to simplify the install problems > everyone is having with gpsim. In me opinion this is a shape easy of install and uninstall, to install news versions. > Scott thanks again :) Nestor A.
