ANNOUNCE: Squeezelite-ESP32 (dedicated thread)

[philippe_44]

Could you please explain where in the manual you found the number of the i2c parameter for the dac_config?

I cannot find the number of the i2c parameter of dac_config in this document. In which section did you see it?

What does the i2c parameter mean within the dac_config? Is this the i2c address or something else?

If it would be the address, should´nt it be 0x10 as this post said?

Not 100% sure of your question, but the syntax of dac_config is in the README of the squeezelite-esp32 project. It has nothing to do with ES82388. ES8388 gives you the value to set, but the syntax is what I "invented" for squeezelite-esp32

[mboxler]

I was basing dac_config on this. I'm confused

[philippe_44]

This is from the FCC document? I'm not sure we should not better trust the schematics

[philippe_44]

I would rather say

model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=32

or

model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=34

or

model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=16

or

model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=17

(I'm not sure what I did for i2c address, if there is a left shift for the R/W bit or not)

[jofland]

I think do should be 25. IO25 (ESP32) ---> I2S_SDIN (ES8388)

Leave the quotes off the value you are changing to...

{"reg":"4","val":60}

Have you played with the register functions in the browser UI? You can display/change resisters from there as well.
It's in the Advanced section.

Mike

I am not sure with or without quotes for the values. I asked before and philippe said with quotes.

No, I have not played with the register functions.



Regarding the documentation:

I'm not sure I know what to believe when I look at the schematics. Maybe you're right and GPIO5 is not BCLK but I'm not sure SCL and SDA are 33/32, they are I2C_SCL not I2C_SCL_ESP, so I think they are 23 & 18

[ATTACH]35299[/ATTACH]

I have seen this too and am confused too. If you look at the next schematics (yellow background) in this document you get more confused...


Regarding the i2c address:

Edit:

From the ES8388 User Guide

The chip address for I2C is 0x20 if CE pin is pulled down to DGND. The chip address for I2C is 0x22 if CE pin is pulled up to PVDD.

Maybe this will work in dac_config???

model=I2S,bck=27,ws=26,do=25,sda=33,scl=32,i2c=32

Thanks for this hint. Although I have read the Readme a few times, I may have overseen it.

bck=<gpio>,ws=<gpio>,do=<gpio>[,mute=<gpio>[:0|1][,model=TAS57xx|TAS5713|AC101|I2S][,sda=<gpio>,scl=gpio[,[B]i2c=<addr>[/B]]]

Which notation <addr> should be? Decimal?

i2c in dac_config uses the address. So we should try one of the following:
* 0x10 as resulted from the test sketch posted some pages above
* 0x20 see mboxler
* 0x22 see mboxler

I do not think we should use 16, 17, 32 or 34 as address as mentioned some posts before.


To sum up: There are to many permutations to try. I would like to find some parameters we can consider to be sure and fix. So we can reduce complexity.

[mboxler]

Sorry, I didn't state something right.

I leave quotes off both values...

{"reg":4,"val":60}

Here's what I have in dac_controlset

{ "init": [ {"reg":45,"val":52}, {"reg":45,"val":48}, {"reg":53,"val":8}, {"reg":54,"val":81}, {"reg":64,"val":24} ] }

It seems to correctly change the registers for me.

- @addr is decimal and should be 16 or 17. I looked at my code () and I do the left shift for the R/W bit
- You can leave the quote off, I always forgot that - my bad
- I think you should try

model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=16
model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=17

Don't forget as well that this board has an amplifier that uses GPIO 21 for power up, so use "set_gpio" to "21=amp"

I have one of the ESP32-A1S boards with ES8388 and am happy to work through the permutations if that's helpful, I'll need step by step instructions though as I haven't set up Squeezelite-ESP32 before.

I suspect all new ESP32-A1S boards now come with ES8388. For reference I bought mine from the AliExpress store linked from the Squeezelite-ESP32 Github readme.

[piPlayer]

When I try to start playback with the toggle command after booting, nothing happens. Once I have started playback with the play command, then the toggle command also works as desired. Only the first attempt after startup does not work with toggle.

No ideas?

I have now contacted many sellers on Aliexpress,all of them confirmed the boards have ES8388 chip

I don't have time right now, but I'll look at that in a few days

[piPlayer]

I don't have time right now, but I'll look at that in a few days

Ok thanks. I don't want to rush you.

[jofland]

OK, time for the next tries

Don't forget as well that this board has an amplifier that uses GPIO 21 for power up, so use "set_gpio" to "21=amp"

Of course I set this. My log shows the amp power up.

I leave quotes off both values...

{"reg":4,"val":60}

Here's what I have in dac_controlset

{ "init": [ {"reg":45,"val":52}, {"reg":45,"val":48}, {"reg":53,"val":8}, {"reg":54,"val":81}, {"reg":64,"val":24} ] }

Thanks, I removed the qoutes and added the curly brackets, although "init" is the only element in the json list. Looks like:
{"init":[{"reg":8,"val":0}, {"reg":4,"val":60}]}

I would rather say
model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=32
or
model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=34

Because of our confusion with the documentation I still do not know which the right values for ws, do, sda and scl are. I will do some permutations and document it here. Tonic or someone else then can take over and document the next permutations until we have a working configuration.

@Tonic: For installation follow philippes manual of post #1 and my post #916 https://forums.slimdevices.com/showt...=1#post1025722
But install software I2S-4MFlash.16.699.master-cmake instead of A1S


For the permutations (out of our confusion from the documentation)

ws = {25, 26}
do = {26, 25, 35}
(of course ws != do)

sda = {33, 18}
scl = {32, 23}
(probably only first elements 33/32 together or second elements 18/23 together)

i2c = {16, 17}
({10, 32, 34) maybe also possible)

reg8: set bit7 to 0
reg4: set bit7 and bit6 to 0 and bit2 - bit 5 to 1
(use explicit setting of the bit or only change the necessary bits (with "and"/"or")
==> Maybe some assembler expert could help here

Let us start with the following permutations until we have success (sound):
* fix: dac_controlset = {"init":[{"reg":8,"val":0}, {"reg":4,"val":60}]}
* playing: 128kb/s CBR, mp3
* reboot after each permutation

Permutation of i2c
model=i2s,bck=27,ws=26,do=25,sda=33,scl=32,i2c=16 ==> I can her something from the speaker, but only random noise; no music; changing volume has no effect on noise; [0;33mW (6170) DAC core: I2C write failed
model=i2s,bck=27,ws=26,do=25,sda=33,scl=32,i2c=17 ==> random noise; changing volume has no effect on noise; [0;33mW (6160) DAC core: I2C write failed

Switch ws and do; change sda/scl; permutation of i2c
model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=16 ==> random noise; changing volume has no effect on noise; [0;32mI (6170) DAC core: DAC uses I2C port:0, sda:18, scl:23
model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=17 ==> random noise; changing volume has no effect on noise; [0;33mW (6160) DAC core: I2C write failed
model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=10 ==> random noise; changing volume has no effect on noise; [0;33mW (6160) DAC core: I2C write failed
model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=32 ==> random noise; changing volume has no effect on noise; [0;33mW (6160) DAC core: I2C write failed
model=i2s,bck=27,ws=25,do=26,sda=18,scl=23,i2c=14 ==> random noise; changing volume has no effect on noise; [0;33mW (6160) DAC core: I2C write failed

==> I guess sda=18,scl=23,i2c=16 could be right because of missing error in the log?

Permutaion of ws and do again
model=i2s,bck=27,ws=26,do=25,sda=18,scl=23,i2c=16 ==> random noise; changing volume has no effect on noise; [0;32mI (6160) DAC core: DAC uses I2C port:0, sda:18, scl:23
model=i2s,bck=27,ws=25,do=35,sda=33,scl=32,i2c=16 ==> no sound; [0;33mW (6160) DAC core: I2C write failed
model=i2s,bck=27,ws=26,do=35,sda=18,scl=23,i2c=16 ==> random noise; changing volume has no effect on noise; [0;32mI (6160) DAC core: DAC uses I2C port:0, sda:18, scl:23

What do you think?

Maybe now it is time for the registers?

[jofland]

One interesting thing:

If I use sda=33,scl=32 the "Scan I2C bus for devices" shows up nothing.

If I use sda=18,scl=23 I get

     0  1  2  3  4  5  6  7  8  9  a  b  c  d  e  f
00: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
10: 10 -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
20: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
30: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
40: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
50: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
60: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
70: -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- -- 
------------------------------------------------------------------------------------
Detected the following devices (names provided by https://i2cdevices.org/addresses).
16 [10h]- VEML7700 VML6075
------------------------------------------------------------------------------------

So it is definitively sda=18,scl=23 and i2c=16 (decimal) = 10 (hex).


Reading the registers 4 and 8 by "Read registers visible through the I2C bus" gives me:

I (293230) messaging: i2cget
0x3c 
I (297640) messaging: i2cget
0x00

That is what I set in the dac_controlset.

[jofland]

Setting reg4 = 48 turns sound (noise) on; reg4 = 12 turns it of. So the speaker output is mapped to OUT1.

Setting reg8 to 0, 128, 1 or 127 makes no difference to the random noise. Actually there is no change in master or slave mode recognizable.

==> So I assume next we should concentrate on bck, ws and do.
