Coding Environment

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.

Here’s what we’re going to cover:

  • Simplicity Studio IDE Introduction
  • Creating a New Project
  • Using EMLIB libraries
  • Enabling FPU and CMSIS DSP Extensions

Hardware Setup

There are a lot of musically savvy engineers who, after their first signal processing course, use their newfound knowledge to build an effects pedal of sorts. I definitely put myself in this category.

Over the next while, I will be messing around with different audio processing methods like filtering, reverberation, wavetables and whatever I feel like playing around with.

For this post, I am going to go through the hardware setup. The firmware setup will be covered in the next post.

The analog front end schematic and a physical implementation example is provided below.
