Hi! I am currently working with an STM32F746G discovery but I am experiencing difficulties to get the audiocodec working. I would like to plug in a 3.5mm aux jack into the blue jack on the board and get the ADC values from the audiocodec to further process them. I found out that I have to use the SAI2 interface but I am kind of stuck now. If you have used it already, could you give me some advice?

Mindblowing lecture sir crystal clear all things.

Button works only once for me. All became Ok after setting -O0 optimisation for compiler in C/C++ tab.

[@timmsagd]

EXTI0_IRQHandler() called two times if I press button once and compiler optimisation is higher than 0. To fix this trouble you can add "EXTI->PR |= EXTI_PR_PR0;" to clear interrupt flag.

It's better not to use delays while you are in EXTI15_10_IRQHandler ;)

Thanks for watching the video. tDelay was not the actual delay but it was a variable assignment to control the toggling frequency. Did I answer you?

Tnx for video, i understand what variable tDelay mean and why u use it. By delay i mean for cycle that making some delay for button bouncing , it's not very good practise to use delays in IRQ, i was loking for some bouncing function without delays. If you have such video i would like to see it, tnx.
