Inside the loop, we first set the output pin on the microcontroller to HIGH (1), then we wait for half the amount of calculated period & then set the output pin to LOW (0) and again wait for half the amount of calculated period. This way, we are operating at 50% duty cycle. Here is a simple output audio I created using the above method
Which microcontroller for audio synthesis/processing ...
https://electronics.stackexchange.com/questions/139792/which-microcontroller-for-audio-synthesis-processing
I want to get started designing my own hardware (digital) audio devices for signal generation and processing. The end goal is to design products which will be part of a modular synthesizer system. I'm a bit of a beginner with hardware so I'm after some advice on an appropriate type of microcontroller to use.
