Naujas puslapis

Mini mp3 grotuvas skirtas veikti su mikrovaldikliais.

[[Vaizdas:Setupdfplayer schema.png|800px]]

Galimi pavadinimai:
* DFPlayer
* MP3-TF-16P
* MP3-TF-16P V3.0

= ESP32 Pajungimas =

* ESP32 PIN 16 (hardware serial2 rx) -> DFPlayer TX
* ESP32 PIN 17 (hardware serial2 tx) -> DFPlayer RX
* ESP32 3V3 -> DFPlayer VCC
* ESP32 GND -> DFPlayer GND
* Taip pat prie RX ir GND dedamas 100k rezistorius.
* Speaker (mono) + DFPlayer SPK1
* Speaker (mono) - DFPlayer SPK2

Žinotina, kad žmonės naudoja ir stereo su šiuo grotuvu (asmeniškai neišbandyta).
Naudojama arduino biblioteka: https://github.com/Makuna/DFMiniMp3

Pavyzdys groja atsitiktinius įrašus iš [[SD Kortelė|microSD]] kortelės, suformatuotos kaip FAT32 palaikoma iki 32GB kortelės. Išbandyta su Good Ram MicroSDHC I 32GB. Taip pat reikalinga tam tikra hierarchija failų sistemoja, norint, kad tinkamai veiktų, plačiau galima paskaityti bibliotekos autoriaus repozitorijoje.
