The last post went into the hardware details for our audio project. In this post, we’re going to cover the coding environment. Aside from the basics, there are some neat features in the microcontroller that we definitely want to use and that’s going to need some extra configuration.
The extra configuration steps sent me on a bit of a wild goose chase throughout the internet so I hope that by compiling most of what I learned into one post, you can get started more quickly.
I can’t believe that it has taken me this long to play around with Atmel microcontrollers. Sure, I’ve used the Arduino platform many times but I haven’t actually programmed an Atmel chip without using Arduino code. I’ve been really interested in using an AtTiny for a project and while I could burn in the Arduino bootloader, I decided that I would take this opportunity to get messy, take chances and make (a whole lot) of mistakes.
Every now and then, I like to play around in the Signal Processing world – more so in the audio realm than anything else. The thought that sound can be represented by an array containing a whole bunch of (seemingly arbitrary) numbers ready for manipulation is just awesome!. Yes, I had a lot of fun in my signal processing labs at school and I still love messing around with GNU Octave post-college.
