Hello,

Are you sure you’re configuring the right GPIOs?

Enabled RCC clock for the GPIO ports?

PS: please in next time either you put the source code in the comment using </> button or simply attach it.

Please don't attach code screenshots.

Thank you.

where is RCC clock for the GPIO ports in CUBEIDE and how to enable this

ST Technical Moderator

Hello,

You need to use CubeMx (in CubeIDE) to configure the peripherals and generate the corresponding code.

I've attached a project running on F411-DISCO board toggling the 4 LEDs. I didn't test it but should work.

Your attached project running fine and all LED is toggling but , what is the issue in my code . can you please help me.

Always use CubeMx to generate a code template.

This does the necessary initialization of the GPIOs including the clock enabling.

Thereafter, simply one line code to toggle LEDs.

refer to the snapshot, and Click the Right-Top Corner to generate the Code.

The one you have circled up is to setup the parameters.
