HiFi DACs for Orange Pi

segmentor

hello i want to make me one hifi.
i need to know if the orange pi mini 2 is compatible with:
1) volumio distro
https://volumio.org/
https://volumio.org/get-started/

2) this pcm5122 i2s dac board

@segmentor: see this thread for a Volumio port: http://www.orangepi.org/orangepi ... &extra=page%3D1

Regarding the DAC I cannot help further, still hoping for someone to help me get mine up and running...

Ok, the DAC arrived yesterday. Connected it to a RPi B running Volumio to test it, works great! I tr ...

According to the datasheet H3, i2s bus pins are: GPIO 28 LRCK, GPIO 29 BCK, GPIO 37 Data
Linux is ready to use a dac i2s? modules etc.
I can not help more but that has not yet arrived my board

Any news about this?

Anyone have tryed i2s really works on OPI?

Hi, i am waiting for arrives Orange PI PC and Audiophonics Dac sabre Es9023 i2s, then i will try the connectiorn

I have the same question

Unoqueva

my DAC must come soon, in my case it is a PCM5102.

I have also seen that in the boot file script.bin there is a section dedicated to the audio that I think should edit to activate the bus i2s

1. [pcm0]
   
2. daudio_used = 0
   
3. daudio_master = 4
   
4. daudio_select = 1
   
5. audio_format = 1
   
6. signal_inversion = 1
   
7. mclk_fs = 128
   
8. sample_resolution = 16
   
9. slot_width_select = 32
   
10. pcm_lrck_period = 32
    
11. pcm_lrckr_period = 1
    
12. msb_lsb_first = 0
    
13. sign_extend = 0
    
14. slot_index = 0
    
15. slot_width = 32
    
16. frame_width = 0
    
17. tx_data_mode = 0
    
18. rx_data_mode = 0
    
19. i2s_mclk = port:PA18<2><1><default><default>
    
20. i2s_bclk = port:PA19<2><1><default><default>
    
21. i2s_dout0 = port:PA20<2><1><default><default>
    
22. i2s_din = port:PA21<2><1><default><default>

Copy code

I think the line "daudio_used = 0" must be "daudio_used = 1" to operate the pin i2s

Muy bueno Unoqueva!

Giachi

in the code wrote from Unoqueva report

1. i2s_mclk = port:PA18<2><1><default><default>
   
2. i2s_bclk = port:PA19<2><1><default><default>
   
3. i2s_dout0 = port:PA20<2><1><default><default>
   
4. i2s_din = port:PA21<2><1><default><default>

Copy code

like here, then the connections for my board Teradak ES9023 i2s can be:

I am not fully sure, bacause in the code writed from Unoqueva PA18 is called MCLK and PA19 BLCK.

The Allwinner H3 datasheet show at pages 74 and 79 say
PA18 = PCM0_SYNC = I2S/PCM Sample Rate Clock/Sync
PA19 = PCM0_CLK = I2S/PCM Sample Rate Clock
PA20 = PCM0_DOUT = I2S/PCM Serial Data Output


I wrote a email to Allwinner... i wait what they will reply
