				Hi,
 
im new here.
 
I don't know if ive done something wrong, but UART1 in the 18f45k80 VSM model doesn't seem to work.  UART2 works ok with and without interrupts, but when i switch connections in proteus and update code to look at UART1, it just plain seems to be dead.And this is with and without the interrupt enabled on UART1.  
 
When i opt for the software UART and use any other pins, it works as intended. Has anyone else experienced this?  Is it undocumented that the UART1 is not modelled?  I know from reading through the notes on the 18 series on Labcenter website that not all features are implemented, but no mention of the serial ports. |

				So ,have you gone through 100% of the source code for PROTEUS and confirmed that it will work as expected ?
 
For years, most understand that PROTEUS is NOT 100% functional. In fact it fails on the simplest of programs.
 
 
Have you actually used real hardware to confirm it's NOT a Proteus problem ? |

				Read the sticky at the top of the forum:
 
"No more Proteus questions"
 
The simulator in Proteus is full of faults, and worse, can make you think
 
things can work, that on a real chip will not, or tell you something does
 
not work when it does. 
 
 
IT IS A WASTE OF TIME.
