In my previous two articles, we examined the core components to an RT600 hardware design using the code name “Super-Monkey”. The objective of the Super-Monkey project to produce minimal configuration design example using RT685 audio crossover MCU that would support my real-time audio processing projects. There is quite a bit IO available on the RT685, but I chose to constrain my design to the most common functions for real-time audio. My applications generally use professional, “flagship quality” audio codecs for musical instrument signal processing. Using this as a guide, the process of coming up with a minimal IO complement was simplified. It is time to now time reveal the Super-Monkey design!
