ESP32 Forum

Hi,

I'm using the following method to connect a pin to a signal:

esp_rom_gpio_connect_out_signal(pin, signal, false, false);
gpio_hal_iomux_func_sel(GPIO_PIN_MUX_REG[pin], PIN_FUNC_GPIO);
gpio_set_drive_capability((gpio_num_t)pin, (gpio_drive_cap_t)3);

I found it somewhere on the internet, can't remember where, but it works fine. The question is if it is possible to disconnect the pin from a signal and connecting another pin without restarting ESP32?
I tried searching the include folder for something like esp_rom_gpio_disconnect_out_signal, but it doesn't exist.

You can't disconnect an output pin; it always needs to be driven by something. You can re-initialize it as a GPIO (esp-idf has gpio_reset_pin for that, should work on Arduino as well) and make it an input or something.,

Thank you for your reply. Since the pin is connected to LCD peripheral, is there something I have to keep in mind while doing it while it's in use? I'm changing the pixel format "on the fly". I don't mind if I get some artefact while it's being changed, if that's the only conncern.
