Here's an announcement I've wanted to make for a while: I'm releasing my microcontroller simulator, MCUS. It's a fairly simple simulator designed to aid in teaching the OCR 2008 A-level electronics syllabus to UK students. As far as I know, it's the only simulator available which follows the new syllabus (for which OCR have deigned to write their own simple assembly language, obsoleting any previous simulators used in schools).
It's already had three releases (this is the fourth), but I didn't want to make the 0.1.x releases too public, as they were mainly for testing the program at school. The 0.2.0 release was a brown paper bag release, due to a bad GTK+ version dependency, and some files necessary for the Windows zip package not being included.
It's available on the MCUS project page, with 0.2.1 being the latest release. A Windows installer is available too, built with NSIS; as well as a simple zip package of the installed directory tree on Windows, since the program's relocatable.
My school is already using it, and I'm releasing it in the hope of other schools being able to make use of it. As always, it's open source, released under the GPLv3+.
Future plans include a graph to visualise the ADC waveform, and the addition of more simulated input and output hardware.
I've just finished converting the site to use WordPress instead of the custom software I'd previously been using. It'd been getting too time-consuming to keep everything maintained and up-to-date with the latest things going on on the Internet, and I'd been reduced to making posts via phpMyAdmin due to various things breaking. Hopefully, this should be better, and a lot less hassle to keep running. I apologise if the transition has messed up the feed for anyone, but I've tried my hardest to redirect all the old URLs, so things should keep working as before.
Recently, I had to compile my computing coursework for Windows, as the person for whom it's written only uses Windows. Much to my delight, once I'd figured out the terminology and basic principles, getting it to cross-compile for Windows using MinGW was quite easy! Since I couldn't find much documentation on the process while doing it, I've written up the steps I took, and perhaps someone else will find them useful.
Last month, I also managed to write up some API documentation for totem-pl-parser, which has been on the to-do list for a little while. It was quite easy to get the hang of gtk-doc, too, and once I'd got started, the documentation got done quite quickly. If anyone's implementing anything using totem-pl-parser, I'd appreciate any feedback on the usefulness of the documentation, as it can always be improved.
I'm writing something for Totem, and I want a GtkTreeView to have more rows added to it as you scroll down.
So far I've got it adding more rows nicely when you get to about 80% of the way down the GtkAdjustment, by listening to the adjustment's "changed" signal, but then it keeps on adding rows (ideally it should only add 20 at a time then stop), and the handle of the scrollbar screws up. I presume this is something to do with the fact that the handle is grabbed at the time, and so probably can't resize, or something.
Anyway, has anybody implemented anything similar before (or seen such a feature somewhere) so that I can see where I'm going wrong? I could've sworn I'd seen something similar before (I'm not original enough to think up such features myself ), but I can't find it. Answers on a postcard, please.
