gpsim, watching variables / ram
by Peter Chant

Rate this Message:
Gentlemen,
I'm having a bit of fun trying to watch my variables whilst simulating a 16F84. I can open the symbol viewer, right click on an item but it does not appear in the watch window. Well it did twice but I cannot replicate that. Alternatively, using the register viewer (RAM), either the simulation will not run with this window open, or I have got segmentation faults (not that I could replecate them when writing this email). The upshot is that I cannot see what the various registers are doing whilst simulating. Any ideas? BTW, speed of simulation combined with the breadboard view is very handy.

Which version of gtkextra do you have installed? There is a bug in older versions of gtkextra that cause the RAM window to hang. Unfortunately, I haven't updated my web page with the proper version of gtkextra - So if you've downloaded gtkextra from www.dattalo.com/gnupic/gpsim.html you're going to see this problem. (And my apologies in advance if this is the case). I just went in and updated the gpsim web page to reflect the more up-to-date information.

When we had our last discussions about gtkextra I think you stated it was no longer used my 0.21.11. Is it possible that I have old gtkextra stuff hanging around causing me problems?

Hmm, i wonder it its worth dropping my current quest and starting over with xwisp2. Looked all over the web site for mention of 2550 and found none, which is why I started doing my own. Seems that others are also interested and I think im nearly there so will continue... if it seems that im getting nowhere then I may drop the project and go for xwisp2.

For ready-made programmer, look at Microchip
PICkit 2 at US$35+shipment. It is a USB programmer and more. pickit-devel project is developing Linux based host software for PICkit 2. For DIY, maybe GTP-USB lite seems to be a good USB counterpart of Wisp628. http://perso.wanadoo.es/j1m/proyectos/gtpusblite/index.htm Together with WinPIC800, it is a nice programmer as well. It is not open source though so alternative firmware and host software needs to be developed for Linux.

For those interested:
At present my programmer is not working, but it does produce the waveforms that are shown in the programming spec so things are looking promising. It interfaces to the host computer via 3 wire RS232. It may be possible to use the power from the RS232 interface to power the programmer and provide vpp, but at present this is done by external PSU. Its wired up on a small peice of bodge board. The host computer sends the 3 bytes (as per programming spec) to the programmer that simply acts as a protocol converter turning the RS232 into clock, data, and vpp. The programmer then echos back the hiByte, which can be used to verify that the comms line is working and also read values from the device. The spare upper 4 bits of the command byte are used as programmer control bits.

Hi Peter, I'm not sure exactly what you're asking in context to what I stated in the past. So let me re-state the issue: gtkextra provides a set of widgets that extend gtk. gtkextra is a separate project from gtk. gpsim uses gtkextra's GtkSheet widget to implement the register window. Now, gpsim made the transition from gtk-1.2 to gtk-2.0 before gtkextra was fully ready. Borut and myself fixed a couple of gtkextra-2.0 bugs so that the code would at least compile and could be used. To add to the confusion, at the time we made these changes gtkextra-2.0 was being called gtkextra-1.1; and that's what you'll see on the gpsim webpage. Earlier this year the gtkextra maintainers fixed these same bugs. Somewhere around May or June gtkextra made the transition to "2.0". I hadn't noticed this announcement, so I continued with the gtkextra-1.1 series. Somewhere around June or July, people started complaining about gpsim "hanging". After some detective work, I discovered that the issue arose when gtkextra-2.0 or gtkextra-1.1 was used with gtk-2.6 and in particular with the row and column labels with the GtkSheet widget. I filed a bug report with gtkextra, but I got no feedback... So as a temporary measure, I turned off the row and column labels in the GtkSheet widget. Finally, a few weeks ago Adrian Portal asked me about a gpsim "stable" release that used gtkextra-2.1 "stable". I wasn't aware that gtkextra had a stable release! So I upgrade to the latest version of gtkextra and discovered that the GtkSheet row and column label bug had been fixed. Consequently, I took out the temporary work around in gpsim. This means if you're using an old version of gtkextra and a new version of gtk, then gpsim 's register window will probably cause gpsim to hang. To summarize, if you've upgraded to gpsim-0.21.11 you'll need to upgrade to gtkextra-2.1.

I did a make uninstall on gpsim and gtk+extra, on both old and new versions of the latter. I did the usual ./configure, make and make install for gtk+extra (2.1.1) . I did ./configure and make for gpsim 0.21.11, however compliation failed when running make, it could not find the right gtkextra library: <snip> /usr/lib/gcc-lib/i486-slackware-linux/3.3.4/../../../../i486-slackware-linux/bin/ld: cannot find -lgtkextra-x11-1.1 collect2: ld returned 1 exit status make[2]: *** [libgpsimgui.la] Error 1 make[2]: Leaving directory `/usr/src/gpsim-0.21.11/gui' make[1]: *** [all-recursive] Error 1 make[1]: Leaving directory `/usr/src/gpsim-0.21.11' make: *** [all] Error 2 root@phoenix:/usr/src/gpsim-0.21.11# It looks like gpsim 0.21.11 is looking for gtk+extra 1.1!

Also in the gpsim INSTALL file it does mention gtkextra-config, this does not exist in gtkextra 2.1.1 unless I am missing something. Am I doing something fundamentally wrong? I'm tempted to put in symbolic links for libgtkextra-x11-2.0* to libgtkextra-x11-1.0* but I'm concerned that that might only make things worse.

OK, I got gpsim built by running configure and then manually changing all of the makefiles t0 gtkextra-x11-2.0 from gtkextra-x11-1.1! A bit long winded, I am sure there is an easier way but I could not find it. The RAM window works fine and I can add values to the watch table using it. However, I cannot use the symbol table to add values to the watch table. Have I still got something screwy with my installation or is this normal?

I'm confused: Microchip's web page [1] makes it look like the pickit2 does not support the 18F devices. Does it? (In my case I want support for the 18F4550) Also: What's wrong with picp for using the Pickit2? There are so many choices & combinations! That's a good thing, right?

PICkit 2 does not support 18F chip yet. However Microchip is
working on it. If you look at the schematics, PICkit 2 is a programmer and more. With the open firmware source, it can be extended to support more PICs. It can do other things as well because it is designed to be very hackable. With its low price and high potential, it is a very good choice for those want a ready-made programmer.

I have released Xwisp2 version 1.8.1 today. Xwisp2 is an alternative support program for the Wisp628 programmer by Wouter van Ooijen. Xwisp2 does not need Python. New with this version: - Runs now really also on a Mac (many thanks 'Easy B.' for helping to fix the dependencies on X86 archticture) - some newer PICs added: 16F68x/90 for some others improved programming speed (with Wisp628 firmware 1.10, provided too) - some minor improvements Xwisp2 can be downloaded from my site, see below.
