DFPlayer - how to pause after each song

userHead projekty 2015-04-21 14:35:13 7122 Views14 Replies
Hi,
Is there a simple solution how to do it without external MCU ? Just on switches and appropriate wiring.
Player must pause after each song and wait for the trigger.
I must play play list in loop.

I've looked into the datasheet but I don't get it.

Thanks

Too bad. For my application this is essential.

One more question.
Is there a possibility that dfPalyer will remember last played song after power off?
What I want is to after power on DFPlayer start song in the remembered location.
Is it possible without MCU?

Standby Current is 20mA accoring to the datasheet.

2015-05-13 13:17:27 What about the current consumption?
Can it be lower?
Actual measured consumption is around 15mA. But I need to set approx 5mA.

Thanks for a TIP... but:
This is very budget project, I do not use any MCU - only passive components.
So no serial communication.

2015-05-07 17:35:35 Hi Projtkty,

have you tried this in Serial mode:

3.4.2 .Commands of Specify Volume
1). Our system power-on default volume is 30, if you want to set the volume, then directly send the
corresponding commands.
2).For example, specify the volume to 15, serial port to send commands: 7E FF 06 06 00 00 0F FF D5 EF
3).DH = 0x00; DL = 0x0F, 15 is converted to hexadecimal 0x000F, can refer to the instructions of playing
track section.

2015-05-07 14:20:03 Hi,
DFPlayer tested.
It defaulty stops after each song and wait for a NEXT or PREV switch to be short.

But here is another issue. After power on it sets a default volume on highest level.
How to make this default level somewhere in the middle?

More. Is the 20mA standby current a minimum value?
Is there something like sleep mode that consumes less?
How to set it while not playing using BUSY pin?

Normally I will disconnect module form power but this causes DFPlayer to start play from beginning after power on.
I need to play in cycle all of the time.

2015-04-27 21:00:51 Well,
Is it means that if this AD KEY will be shorted for all time the player will play all songs in loop?
I want to avoid adding MCU. This circuit must be as simple as could be.

2015-04-23 18:23:37 Hi,

i am not familiar with this module, but i checked the
https://www.dfrobot.com/wiki/index.php?title=DFPlayer_Mini_SKU:DFR0299#Connection_Diagram%20wiki%20page
1 AD Key
there is a key called "loop",is it what you want?


2 by the way, with MCU, you could check the player state,whether playing or not, so you could control the player by Serial mode. userHeadPic Leff
