[Orange Pi 4 LTS - audio I2S output on GPIO ( 26 pin header ).]

Not exactly...

I did something byself - enabled i2s1, added i2s1 sound card (not sure if it works). 😄 But the GPIO overlay is too complicated for me.

 

        i2s1 {

            i2s1-2ch-bus {
                rockchip,pins = <0x04 0x03 0x01 0xb9 0x04 0x04 0x01 0xb9 0x04 0x05 0x01 0xb9 0x04 0x06 0x01 0xb9 0x04 0x07 0x01 0xb9>;
                phandle = <0x9b>;
            };
        };
 

Pins? GPIO? What addresses to write here?

Hi

 

I want to use the I2S GPIO output pins ( 26 pins ) on Orange Pi4 LTS to connect multi channel DAC.

Is it possible to overlay some pins?
