ES8388 - AiThinker - broken about wled HOT 17 CLOSED

Just checked and no error, but silence and no passthru, need to double check the config is right

from wled.

If the initialisation fails, we need that to be showing on the info page, not just silence

good point, I'll add a message tomorrow. I'll also check if a "frozen" message (discussed some month ago) can be added easily.

@netmindz I think we can close this now?

Let me just double check with this board as well as the LyraT

This one comes from four line display. It should not cause any problem, but you could check if disabling the usemod makes a difference.

I2C write failed with error=2

i2c error 2 is NACK when sending the address - either the Es8388 address (0x10) is wrong, or the I2C pins ( SDA=33 SCL=32) are wrong/swapped.

@netmindz: your I2C config seems to be correct, at least according to information I found here: https://www.pschatzmann.ch/home/2021/12/06/the-ai-thinker-audio-kit-experience-or-nothing-is-right/

So maybe its really some interference with four-line-display drivers. un-checking "enabled" in the fourline-display usermod setting, then reboot, might help.

I just tried the alternative pin combo for I2C on some boards and I get

AR: ES8388 Source (Line-In)
ES8388Source:: initialize();
PIN Manager: wire.begin successfull! I2C bus is active. SDA=18 SCL=23.
I2SSource:: initialize().
AR: I2S#0 driver without aPLL; fixed_mclk=0.
AR: 32 bits, Sample scaling factor = 1.0000
AR: I2S#0 driver installed in MASTER mode.
AR: FFT task started on core 0 [prio=1, min free stack=|| loopTask min free stack 4360
AR: sound input driver initialized successfully.

But still then silence and still no audio passthru

Looks like a step forward - no i2c errors means that AR could talk to the chip 👍

I'm annoyed i never took a screenshot of the setting when I had my board working, the notes on the docs are from @troyhacks and this board is notorious for having 3 variants

from wled.

Maybe this table helps: https://github.com/pschatzmann/arduino-audiokit/wiki/GPIO-Overview-by-Selected-Board

If SDA=18 SCL=23 works for you, then it seems you have the variant in column 7, with
SD=35, WS=25, SCK=5, MCLK=0.

Ah, great find @softhack007
