AI-Thinker A1S Audioboard
Hello;
have such a board here... with a lot of reading I got an Arduino code to work
this Board has an integreted ES8388 I2S Audiochip on board
has some body expierieces to got it to run with annex basic? or could it be integrated as a "module"?
I have already tried all possible settings in the "config"
the ESP works in itself but I get no audio (stream) to hear wifi at all is ook
Thank you for your efforts
Ron

Re: AI-Thinker A1S Audioboard
in the attachment still the data sheet of the Es8388
- this would have to be initialized before use annex play.xxxx
It worked once when I switched from Arduino to Annex
the initialization probably remained in memory
could somebody help me writ a suroutine for I2s initialisation ??? found this still

Re: AI-Thinker A1S Audioboard
hi, thanks
but i have used the pinouts from the working ...ino code doesnt work
the es8388 must be initialized unconditionally is also done at Arduino have changed a post see please3 above

As I said I have already tried it and it ran once when changing from Arduino to Annex must have been the initialization still in memory[Local Link Removed for Guests] wrote: [Local Link Removed for Guests]Wed Mar 22, 2023 4:04 pmyou should set BCLK=27, WSEL=25, DOUT=26 but, looking at the code, it seems that the DAC requires the MCLK signal that is not actually supported.Code: [Local Link Removed for Guests]

Re: AI-Thinker A1S Audioboard
I even took pictures because I was so happy but after a power off nothing worked anymore

Re: AI-Thinker A1S Audioboard
You can still play with Arduino, it's so easy to use
Unfortunately the MCLK signal is not considered as most of the I2S DAC do not use it

Re: AI-Thinker A1S Audioboard
If I wanted to, I wouldn't have asked here - can you help me write such an init code?[Local Link Removed for Guests] wrote: [Local Link Removed for Guests]Wed Mar 22, 2023 4:25 pm You can still play with Arduino, it's so easy to use

Re: AI-Thinker A1S Audioboard
With peek and poke should be possible ... maybe the guy that asked for these functions can do the job
this is what must be done
The datasheet is here
https://www.espressif.com/sites/default ... ual_en.pdf
starting from page 48
edit:
probably is simpler to integrate in the code?
