hello everyone,

I am doing small project, I will explain what my product is.

It has 2 sounds in a memory and I need 2 buttons for each sound and one button to pause and play.
so I choose this as cheap chip for do it.

But I do not know how to get the keys I want ., I mean they have provided next , previous, play, stop , keys. but How to dedicate one key for one sound and other key for other.

I got one method. I load only 2 sounds to chip. so if chip does not load sounds as loop, then next key is for sound 2 and previous key is for sound 1. will it load music files as loop, I mean after final mp3 files reads, then will it start from 1st or repeat last one?

or any other method without extra micro controller.

thank you
