STM has an example project called “Audio playback and recording using the STM32F4DISCOVERY” - application note AN3997 was made to give instructions on how to use it. But even with this application note I can’t seem to get it to run.
When I open the project, System Workbench doesn’t recognise it as a C project. I tried to Configure and Detect Nested Projects and it set up two C projects: MEDIA_InFLASH and MEDIA_USB_KEY which are the workspaces for running the program with the internal flash and USB respectively. However, neither of these have src or inc folders and they both throw up a lot of errors. I tried setting up a new C project and copying across all the relevant subfolders and got more errors - missing include files, unrecognised functions and variables.
I’ve had a lot of frustration getting this example code to do what it’s intended for. Am I missing something obvious?
I have attached the application note.
