Hi there,
thank you for your compliment.
Unfortunately the RTC module itself respectively how to configure a RTC with CubeMX isn’t a part of our daily work nor a necessary part for the Embedded Wizard solution.
I only can forward you to our ready-to-use example named ‘Example/BezierClock‘. Have you already seen that example?
It also uses the RTC from the STM32F746 Discovery board and the RTC module is configured in ‘TargetSpecific/ew_bsp_clock.c’. Maybe this could help you to find out how the RTC module have to be configured correctly.
Best regards,
Tim
