The TI-Nspire has a serial interface in the dock connector at the bottom of the calculator. The easiest way to access this reliably is to simply solder a wire onto it but that's obviously not an option for some people. A few people in the community have come up with some interesting designs for a home … Continue reading Idea for TI-Nspire serial adapter
Update: For a much more in-depth analysis of the problem, head over to Naked Security where Paul Ducklin explains the bug in much more detail. Gizmodo recently published an article about OS X Mountain Lion crashing when the text File:/// is typed into TextEdit, Spotlight, Mail or some other OS X apps. It's also reported … Continue reading File:/// crash in Mountain Lion workaround
Status updates are now available from the wiki entry on Hackspire.
I've completed a boot loader that loads Linux and ramdisks and replaces that TI-Nspire operating system in-place. This should have multiple improvements over the old one and values are not hard coded as much as possible. Github source
I've just begun a port of Linux to the TI-Nspire CX and I'm happy to say I have a minimal kernel booting successfully on the calculator! Here's the UART bootlog and you can see we actually make it to userland without crashing! The minimal port has support for the interrupt controller and the timer. UART … Continue reading Linux Kernel port to TI-Nspire CX
I found my old GameBoy Advance consoles and found that I've never done any development work on it and decided to play around with it. Unfortunately, I don't have a flashcart and it's difficult to find decent ones to buy on the internet anymore. The only option to actually upload code was to use the … Continue reading GameBoy Advance development
One of the biggest show-stoppers in writing a bFLT file loader for Ndless was the lack of documentation with the bFLT file format. Information was scattered everywhere and it was hard to find how to implement some specific feature. I decided to write a simple description of all the features in bFLT and how to … Continue reading bFLT format – implementation notes
I've been struggling for quite a while now on the best way to implement a movie player for the NSpire calculator. nPlayer was also born around the same time and I realised there were other's trying to do the same thing as I. I had to gain an edge over them. I immediately identified a … Continue reading A movie player for NSpire. Finally.
So, a few weeks ago, I posted something about using C++ with the Ndless framework. Unfortunately, while the compiler worked, the end binary kept crashing. I figured that it was because of the C++ vtables having invalid function pointers. The linker wasn't updating them correctly. This was the same problem when doing static declarations to … Continue reading ELF loader for Ndless
The more I work on nspire-gamekit, the more I think a object orientated programming language would be more suitable for the task. I'm currently playing around with C++ and getting it to work with the ndless SDK (which doesn't natively support C++). It is very likely I will consider making the whole project object orientated … Continue reading Getting a C++ compiler for Ndless
