Connect to AC101 codec.... Failed! #6

Hi Marcel,

My ESP32-devkit-board has just arrived and wanted to see what your project does. After flashing my devkit-board i see:

Connect to AC101 codec... Failed!
Failed!
Failed!
...

I read a post somewhere about that recently the exact used chips were changed. Just leaving this information here for others... I've not looked into a solution/workaround.

greetings, Sander

Hi, it seems this board does not have the AC101 equipped. The newer version uses the ES8388. You can try the I2C scanner first with the following settings:

define ES8388_PIN_SDA 18

define ES8388_PIN_SCL 23

You can find configurations on the internet, but I am also working on an update using the ES8388. Best regards

Has been fixed in the past. ES8388 supported in other projects. I've added the ES8388 driver which will be active by setting ES8388_ENABLED

Hi Marcel, thank you for your effort. Yesterday i tried it with the ES8388_ENABLED flag and things seemed to work. On my board a red led started blinking at a rate of +/- 2 Hz. In the Arduino log the output scrolled by at a fast rate. I'm not sure what to expect further. Anyway.. Thanks again for your effort and your reply. Hereby my confirmation that the flag does seem to work.

Hi, sounds great. To avoid to much log output you can turn of the VT100 (if enabled). It can be also caused by active ADC without pots connected.
