STM32MP1 support available in SW4STM32

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world.
And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4; you can download a short video showcasing this on the ac6-tools website (registration required).

Make a simpel tone on Stm32F7

HI

This one give me a tone, but it do not stop...it continue and the stm32f7 do frezee ........anybody with an idea ?

  1. include “stm32746g_discovery_audio.h”
  2. include “stm32f7xx_hal_sai.h”
  3. include “stm32f7xx_hal_i2s.h”
  4. include “main.h”
  5. include “GUI.h”
  6. include “DIALOG.h”
  7. include “WM.h”
