Thanks, Andrew. I hadn’t gotten into Arduino, thinking it was for beginners just trying to blink lights and run motors on cheap little microcontrollers. It does seem like they have made the setup a lot easier than the ARM C++ universe. The audio support (hardware, libraries, examples, and documentation) seems pretty weak, though.
If I could make one request that would be hugely helpful: We need a tutorial that explains the callback framework. This seems to be the bedrock that all Daisy apps build upon. I am not talking about the function documentation or a code example on Github. I am talking about a real English tutorial that explains what is going on from analog into the codec, through the drivers and libraries, to the user app, and then back to analog out of the codec. A simple example program like tremolo would be perfect. Then you can explain how slower control functions like an LFO works within the framework of the real-time audio processing.
I think it would be really instructive for E-S folks to go back and look at the Spin FV-1 website:
at Spin Semiconductor - Knowledge base
You have to admit that they did a masterful job. They taught an army of folks how to build effects on their hardware, despite the primitive tools and bizarre instruction set. And no CS degree required!
