Yup I’ve jumped to a bathtub test and bypassed the lovely soldering and coding… will revisit later but here’s the video :-

It’s taken me a while to officially start this project.  When I first bought my Mazda 3 I had envisaged making my own speedometer based off the Mazda CAN Bus but somehow never quite got around to it.

I even ended up buying 2 Chumbies for the purpose of hacking one and developing the same speedo (The chumby is such a great alarm clock I couldn’t live without one…).

There has been quite a bit of interest in the comments for source code/information etc etc.  So now I’m officially starting the mChumby project!  This first post is basically a brainstorming session write-up or a mini requirements specification on myself.  Feel free to comment on any ideas/improvements you think I can make.

(This post seems too wordy without a photo but I’m just too lazy)

Well this chronicles my first attempt at compiling a toolchain for programming ARM’s in ELF code.

Why do I need a toolchain for programming ARMs?

1. I found a LPC2378-STK development board in my room
2. I want to give ARM programming a try (PS WinAVR is great for programming AVRs)
3. I found I have some spare ARM7 LPC2378′s lying around (WTF?) and thought I’ll actually complete my Chumby Speedometer on my car project!
