Hi there,
Thanks for your updating!
@funax, glad to hear it works. Yes, there may be some card unsupported.
Yes, from the datasheet of vs1053 it appears it could play m4a, however we did not test that. We only tested the function listed on the music shield user manual.
If you want to test it, I don’t think it need extra configuration, just as playing normal music file.
We have one record button, multi-used with play/stop button.
You mean it is not convenient to use record function as described in the user manual?
We may give up so many buttons, replaced by rotation switch in the next version.
Regards,
