Hi,

Got it ...

Devices affected: 16F1826, 16F1827
Date encountered: 08/2009
Error class: safe (always reported)

There are invalid port aliases in the PBP header file for these parts. The following assembly errors will be generated:

Symbol not previously defined (PORTC)
Symbol not previously defined (TRISC)
Workaround:

Edit the files 16F1826.BAS and 16F1827.BAS (found in the PBP install folder) as follows:

PORTL VAR PORTB
PORTH VAR PORTA ' PORTC invalid, change to PORTA
TRISL VAR TRISB
TRISH VAR TRISA ' TRISC invalid, change to TRISA
This is from a Melab's errata sheet Darrel Pointed at some times ago ....
I made the mod a while ago ... so couln't see what's wrong.

Have a nice evening

Alain
