I want to use them without arduino board, ..............is it possible to configure these mp3 modules as i want ?
Sorry no.This is an Arduino forum and you ask about a project that you do not want to use an Arduino with?
Maybe he wants to make his own stand alone board using the chip from the arduino? I do this all the time.
i want to use the mp3 player module that is meant to use with arduino as a standalone board,
but how do i set this mp3 module to work in that way - mode?
Resistor settings control mode in front of the module, marked with ABC character defaults module 010,
is it possible i use the sound module only for sound triggering with momentary switches, and then use this ds1669 circuit for volume control with buttons:
From the datasheet i see that the default settings for jumpers is 010 so 1 means empty and 0 means jumper (332 resistor)
And for the electronic volume control i search for a finished module to buy,
what DS1669 chip do i need 10 kOhms, 50 kOhms or 100 kOhms if i use with 1. mp3 module
and also what do you think about the sound quality
IO port selection control mode application (3.3K ground zero, to float a), the default value 010:
