How to clean all the pins with GPIO_PortClear?

Hello,

It's not possible to use GPIO_PortClear so?

GPIO_PortClear((void*)base[i], 0u << pin[i]);‍‍

I want to turn off all the leds but that not works, only with 1u but turn on all the leds. I have changed the logic in pin_mux but not works to me.

The 7 segment led display that I'm using is common anode.

PIO_PortClear((void*)base[i], 0u << pin[i]);

does nothing because writing a 0 to that register has no effect.

You need

GPIO_PortSet((void*)base[i], 1u << pin[i]);
