Is it possible use this midi sampler with i2s pcm5102a

[ograndebe]

I Have an i2s pcm5102a DAC board here, I tried to read the code and see if it's possible to use this sampler with the DAC I Have, but I didn't find an answer.

Thank you

Hi,

yes it is possible. All projects do support this DAC

Good. There's some guide teaching how to wire and configure the headers?
It's not clear to me the proper configuration and wiring.

Hi. I found this markdown file that explains how to wire and make it work https://github.com/marcel-licence/ML_SynthTools/blob/main/extras/ml_pcm5102a.md .
I found an issue, when I define OUTPUT_SAW_TEST the https://github.com/marcel-licence/esp32_midi_sampler breaks the build. (I'll open an issue at the proper repository)

So, after wiring properly, and enabling NOTE_ON_AFTER_SETUP I had no sound (using esp32_midi_sampler). After that, I tried the https://github.com/marcel-licence/esp32_basic_synth I hear the sound.

I have many questions now, but I'll put the question in the proper places, Thank you in advance.

PS: I Believe that the build problem is related to lib version, I suggest that you start to create tags to manage library versions and in each example repository define the version requirement (my background is programming not electronics)

Hi, I would agree having tags might help but it is very hard to test the different possible configurations. I decided to create a central lib to be able to fix problems for all projects at the same time.
I've seen the question about the opto-coupler. It might be deleted?

I started to create some markdown but it is not all linked. I will try to get a better documentation in future for easier navigation to different topics.

Regarding the wiring; I've added some output visible in the serial monitor on startup.

Thank you very much for your feedback.
