Hi Rui and Sara,
Thank you for the interesting article.
May I ask why you chose to use button interrupts rather than polling the button states in loop()?
I looked at the library example:
https://github.com/bluejunimo/YX5300_ESP32/blob/main/examples/volume_control_buttons/volume_control_buttons.ino
Mainly to check if it also used interrupts, and whether it had a comment saying why so, but it doesn’t use button interrupts.
My initial question (to myself) was “is the library able to cope with being called from two different contexts (loop(), ISR) at the same time?” That’s why I looked at the example.
I suppose the only way that could happen is if the user was adjusting the volume at (roughly) the same time they pressed one of the buttons.
In the worst case, the mp3 object could be in the middle of processing a call from loop() and then the ISR would access the mp3 object. I haven’t checked the library source code to see if it copes with this situation.
I’m thinking of making a project with one of those modules. I may investigate the library source, although I’ll probably use some FreeRTOS feature to provide mutual exclusion, because I don’t know how easily I’ll be able to understand the library code.
Best regards
Dave

Hello, do you know if we can use this with an lcd screen output along with bluetooth connection?

Can you take the audio out of the yx5300 and feed it into PAM 8403?

Hi.
Thanks for your comment.
Can you please clarify your question? I’m not sure that I understood it.

Hi.
I’m not familiar with that module.
It seems to work with serial commands too.
But probably uses a different chip.
On the DFPlayer product page they provide a sample code.

Sara

Such a good tutorial, do you have any experience with DFPlayer Mini? what difference there is between DFPlayer Mini and YX5300?

how do you print this off with out the extra.
It looks interesting
can you make it in to an audio streaming monitor?

In the past I’ve had a bit of issues getting mp3.playTrack(x); to play the correct file I want. I probably was getting the folder/file format wrong and this article lays it out well, but, I found that it played the correct track if you add the audio files one at a time and keep track of the order you added them. For example, if you add three files, one after the other, then run mp3.playTrack(2); it’ll play the second file you added. Hope this helps someone!
