Your comments got me thinking further so I downloaded the "Full" version of PBP3 and installed MPLAB 8.9 and got my code to compile and run with out commenting out the line in the PBPINC file. I compared the Microchip INC files and found that MPSAM 5.49 that installed from the full PBP3 download only had entries for SPBRGL and SPBRGH while MPASM 5.56 (Installed with MPLAB-X) had SPBRG (the offending one) SPBRGL and SPBRGH. The data sheet for the pic refers to SPBRGL and SPBRGH as 2 8 bit registers but refers to SPBRG as the combined value of the 2 registers. In the MPASM 5.56 inc file (MPLAB-X) SPBRG and SPBRGL have the same address, so in effect that is saying that SPBRG abd SPBRGL are the same thing, thus, you are defining the same thing twice or in different places (as per the error message) when you are using MPLAX-X with MPASM 5.56 and PBP3 but not when you are using the older version of MPLAB with MPASM 5.49 and PBP3. My solution is to comment out the line out in the PBP3 .PBPINC file on the basis that I think PBP3 should be compatible to MPASM, rather than the other way round. I wonder if this could be considered a "bug" ? - which came first - the chicken or the egg? Chris
