Good morning,

I am working with an Esp32S3 and I have pins that are configured as I2S peripheral pins.
(Bit CLK pin).

I would like to know if I can keep the same configuration for this pin (I2S Bit clk) and
configure it as output open drain with pullup at the same time ? (via gpio_config method).

Can the two configurations be available at the same time please ?

Best regards,

Thomas TRUILHE

Yes, it is possible. But not via the public (GPIO) API.
You can configure the pin as GPIO, then 'manually' reconnect the peripheral signal to that pin. Like this.
