Category: None Group: None >Status: Pending >Priority: 1 Private: No Submitted By: marco_gaio (marco_gaio) Assigned to: Nobody/Anonymous (nobody) Summary: Can't find PORTA_bits definition for PIC16F84A Initial Comment: Dear all, I cannot find the definition of PORTA_bits, RA0, RA1 and so on for PIC16F84A and for many PICs (if not all, I didn't check) with 14 bit core. I already posted a similar topic and got a reply to download the latest SDCC version. The point is that I downoaded the latesd SDCC 6.0 for Win32 from: http://sourceforge.net/project/showfiles.php?group_id=599. I also downloaded the latest 6.0 tar archive of the sources (sdcc-src-2.6.0.tar), and had a look inside some headers (pic16f84a.h, pic16f819.h, ..) but I couldn't find the aforementioned definition. I can find it in the pic16 port, but I couldn't copy the same definitions inside my pic16f84a.h file. What am I missing? Thanks a lot, be patient since I'm new to SDCC.

I'm new both to SDCC and to this kind of forum, sorry if I put some confusion into it. Thanks again also to Raphael, I will look for the nightly sources and try as suggested. I'll let you know. Regards, Marco ---------------------------------------------------------------------- Comment By: Maarten Brock (maartenbrock) Date: 2006-11-24 14:23 Message: Logged In: YES user_id=888171 Originator: NO Marco, There is no version 6.0 of SDCC. At our speed that will take another 40 years. Apart from the official releases we also have nightly snapshots available from our website. When Raphael said to get the latest he meant those snapshots (or get source code directly from SVN). And instead of opening a new tracker item you also could have added to your previous one. Since you logged in when filing that report you even could have reopened it. I've set this one pending now so it will close automatically if you do not respond within several weeks but will reopen automatically if you do. Hope This Helps Maarten ---------------------------------------------------------------------- Comment By: Raphael Neider (tecodev) Date: 2006-11-24 14:19 Message: Logged In: YES user_id=1115835 Originator: NO Hmmm, my mistake. 1. The PORTA_bits declaration is only available in the nightly snapshots (e.g., sdcc-snapshot-*-4482.tar.bz2); the 2.6.0 release did not have them. 2. Even the snapshots only have few PORTx_bits declarations, namely the 16f84 and 16f84a. So, your best start for now would be to copy pic16fXXX.h and pic16fXXX.c from the library sources into your project, modify them according to your needs and link them into your project. You might need to specify --nostdlib so as to prevent sdcc from linking with the (unmodified) pic16fXXX.{o,lib} from the library, but then you will have to manually link against libsdcc.lib. In other words, you might need to use sdcc -mpic14 -mpic16f84a --nostdlib -L/path/to/sdcc/pic/libraries -llibsdcc.lib main.c helper1.o helper2.o helper3.o pic16f84a.o until I or someone else comes up with a script to regenerate the device headers/libraries with appropriate declarations and definitions. Sorry for the confusion, Raphael ---------------------------------------------------------------------- You can respond by visiting: https://sourceforge.net/tracker/?func=detail&atid=200599&aid=1602242&group_id=599 |
