Parallel I2S: falling edge instead of rising edge clock?

[michikite]

Is there a way to tell the esp32 to sample data at the falling edge of the clock instead of the rising edge, when sampling parallel data through i2s camera mode?

You can simply use the GPIO matrix to invert the signal. Use esp_rom_gpio_connect_in_signal() and pass true as the last argument.
