DF Player Mini mp3 how drove it by pic16f88 by UART APPEND

[leo73]

Hello to MikroElectronic People
I rewrote together XmaxPako the WTV020-sd ad4 player module library in basic code in Lib Stock..........
Now I bought a DF Player Mini mp3 module but i have more problems to rewrite the pic basic driver code for this new Mp3 audio module.
There's a Arduino C Code in a web yet but not in Microbasic or MikroC code.
My Idea is Connect this module to the 16f88 pic using RB5 and RB2 as Pin UART Communication and Rewrite the Cod Basic and C Pic.

In Attacment there's DF Player Mini mp3 module documentation and some example about Arduino Code library, if someone read this post could me reply and help me?
Thank you so much.


my code is this but not work:

' ****************************************************************************
' UART pins is RB5 and RB2
'--> RB5/SS/TX/CK
'--> RB2/SDO/RX/DT
'-------------------------- SOME COMMAND EXAMPLES ----------------------------
'example 7E FF 06 03 00 00 01 FF D5 EF --> Play First song 001.mp3
'Send_Buffer[3]=0x03 Send_Buffer[6]=0x01
'example 7E FF 06 06 00 00 0F FF D5 EF --> set Volume to 15
'
' For example, select the first song played, serial transmission section: 7E FF 06 03 00 00 01 FF E6 EF(last FF and E6 isn't correct, some people suppose !!!! i don't know)
become >>> 7E FF 06 03 00 00 01 FE F7 EF
' 7E --- START command
' FF --- Version Information
' 06 --- Data length (not including parity)
' 03 --- Representative No.
' 00 --- If need to acknowledge [0x01: need answering, 0x00: do not need to return the response]
' 00 --- Tracks high byte [DH]
' 01 --- Tracks low byte [DL], represented here is the first song played
' FF --- Checksum high byte
' E6 --- Checksum low byte
' EF --- End Command
'
' For selections, if choose the 100th song, first convert 100 to hexadecimal, the default is double-byte, it is
' 0x0064.
' DH = 0x00; DL = 0x64 ----Command----> 7E FF 06 03 00 00 64 FF D5 EF
' If you choose to play the 1000th, first convert 1000 to hexadecimal, the default is double-byte, it is 0x03E8
' DH = 0x03; DL = 0xE8 ----Command----> 7E FF 06 03 00 03 E8 FF D5 EF
'
' For example, specify the volume to 15, serial port to send commands: ----- Command ------> 7E FF 06 06 00 00 0F FF D5 EF
' DH = 0x00; DL = 0x0F, 15 is converted to hexadecimal 0x000F, can refer to the instructions of playing, track section.
'
' Specify playback device –TF Card -----Command----> 7E FF 06 09 00 00 02 xx xx EF
' Specify folder 01 of 001.mp3 -----Command----> 7E FF 06 0F 00 01 01 xx xx EF
' Specify folder 11 of 100.mp3 -----Command----> 7E FF 06 0F 00 0B 64 xx xx EF

did it work ?

[leo73]

Yes it work, search the code in libstok site too.

[craftsman42]

ı cant find libstock about df mını player can you send me link?

[craftsman42]

by the way ı was find but it is not df mını player

[leo73]

Haaa no no , i'm sorry the code not work, i'm seaching to write a right code for this device !!!!
did you have some idea about this ??
It's passed many time about this problem, if you want i could search some arduino code and traslate it with you !!!

[leo73]

Or if you not need HI-FI application you can take this library:

https://libstock.mikroe.com/projects/vi ... 7-feb-2016

This is a drive for wtv020-sd device , you can play .ad4 audio file, it used for robots.

[craftsman42]

thanks a lot but ı cant to again have ı use max232? ıf honestly ı want to write library for df mini player on micro c . but ı cant change arduıno library to micro c
can you guide for me ?

[leo73]

Hi craftsman42
I''m tryed to traslate code another time (from arduino c) but the code don't work, we need some-one else us in this forum.
I put in attachment My code and Arduino so some-one can compare and understand were is the problem.
For a moment you can print the code below and compare, after see me your thinking !!!!!

[xvinny]

The pdf manual contains a lot of errors and things missing.
I'm writting a solution for PIC18F46K22, and when I finish, I`m gonna post here.

[xvinny]

I'm using DFPlayer with a PIC18F46K22.
The first thing that I discovered was that its manual has a lot of errors.
Second is that the application circuit in the manual has some problems like potential difference (on GND).
I'll post some tips and tricks using this audio module later.

[leo73]

Ok Xvinny we'll wait

[leo73]

Hello Xvinny,
What about the manuals i understood the problem, because today the manuals is wrote quickly and there's a lot of mistakes and no examples. This is one of reason because is hard to understand how program or use the electronic chips.

Thanks to everyone for the useful info. I'm also running a PIC16F88 controlling a DFPlyer mini.
