Back to Basics – Audio Output on the Raspberry Pico using PWM
In one of my past Blogs I have described how to implement a simple tone generator using a Repeating Timer for the Raspberry Pico with the C++ SDK. This time I want to describe an approach which is a little bit more versatile: The Pico provides no built-in DAC and thus we have no real analog output, but we can generate PWM signals on all pins – so if we use a basic PWM frequency Read more…
