ESP32 Forum

Hi,

I'd like use the GPIO43 on ESP32-S3 as Input.

I'm doing this (I don't know what I have to put on <XX>):
[Codebox]
gpio_iomux_in(GPIO_NUM_43, <XX>);
gpio_config_t config{BIT(43), GPIO_MODE_INPUT, GPIO_PULLUP_ENABLE, GPIO_PULLDOWN_DISABLE, GPIO_INTR_POSEDGE}; gpio_config(&config);
gpio_install_isr_service(0);
gpio_isr_handler_add(GPIO_NUM_43, button_handler, this);
[/Codebox]

How do I have to do to use the GPIO43 as Input?

Thank you

Hi,

I found the solution:

Note the gpio_set_direction is not needed, and generally you want to install the interrupt handler before you configure the GPIO to generate an interrupt.
