Question

STMF407G-DISC1 LED are not changing in project, despite value changing correctly

Hello,

I made simpler project, where led is switched on button to represent binary, and there it works. Two RNG values (0-7 and 8-15) are generated and with button press switches between LED binary representation of two RNG values.

I made the same thing in main project and it don't work there. If first RNG number is 6 or 7 it work fine, but 0 to 5 LED dont change to other number.

I debuged it and the values are changing correctly, checked memory in Build Analiser and its fine there too, i have DSP filters there that change to same value and they works fine. What could be the reason why it dont work now.

main project:

    Variables you change in interrupt/callback will need to be volatile

    You could check the LED code by cycling through the mode value with a delay.

    Changing to volatile dont help, i dont think it is a issue because value are changing, changing filter work, but the same variable dont work with LED.

    LED cycling dont work too, but it work in fresh project.

    So is it ending up in the Error_Handler() or HardFault_Handler() ?

    Have you checked the GPIOD initialization / register in the debugger?

    Unfortunately "Not Working" is not an unduly helpful observation, you'll have to dig into WHY

    Break the problem down. Put sections onto their own functions. Do the cycling test, then investigate why the changing doesn't work.

    Make sure it's not stuck in an interrupt storm, where the main() loop never gets to execute.
