Posted on July 04, 2016 at 01:00I am trying to use the STM32 for audio applications, the end goal being to create a dsp effects unit. I'd like to be able to set up a sample rate for the output instead of it being based on however long the code within the while(1) loop takes to execute, which would change based on what kind of processing it is doing.
The main thing I need out of a sample rate is the ability to set up precise delay times, where the number of samples in a delay has a stable relationship to an amount of time. I also need to control the sample rate to prevent memory issues in this application, since if the while loop is running very fast my sampled delay buffer will fill up very quickly and I will not be able to achieve longer delay times.
This is my first experience programming microcontrollers, in the past I have mainly worked in a computer environment. Sample rate is always one of the first things that gets set up in my experience with audio programming. Is there a reason that wouldn't apply when using a microcontroller?
