I'm currently planning out a project that involves building a OSC controller using an ARM chip. I hope I will be able to use scheme to write the firmware for the device, that would be swell (and much more fun than using ASM).
I experimented with other languages/things before for embedded programming. I think forth would be great if it worked the way my brain does. Otherwise, there are good reasons everybody uses C.
I have very little experience programming so i figured an embedded system would give me a good "ground up" approach to learning some programming. I've heard good things about lua, i was considering ADA (rock solid stability is key for this project) or smalltalk. I'm still in the planning stages of everything involving this project and infact i'm going to build a midibox first to get familiar with embedded systems and circuit design. Some people have made some impressive controllers, and synths with the project.
