I'd like to create a program by which I can record and listen sound by using my board, STM32F746G-Disco. I'd like to use BSP library, however, I have some questions.

When I looked at the stm32746g_discovery_audio.c file, I saw that there are 2 global variables named haudio_out_sai and haudio_in_sai, and there are some functions that configures these sai components. Then do I need to enable and configure SAI components in CubeMX? Because in the documentation of the library, it is said that the functions configure the related components about the audio, but these functions don't take any SAI parameters so I cannot initialize them with the variables that CubeMX defines.

  • Do you start with empty project with only empty main.c? Or what is your starting point? Commented Jun 28, 2022 at 18:46
  • I will need to use XCUBEAI so I don't want to start with an empty project. Now I created a C project. My friends said that I need to enable everything involved in the program as a formality. I did that but I have still a problem as I mentioned in the other question. Commented Jul 17, 2022 at 8:57
