PowerBroker2 / DFPlayerMini_Fast

Fast and easy to understand Arduino library to use the DFPlayer Mini MP3 module from DFRobot.com. This is a huge improvement (both in terms of execution speed and simplicity) to the standard library provided by DFRobot.com.

DFPlayer mini volume level in all new chipsets #49

Hi PowerBroker, I just wanted to share what I figured out with the volume setting. With all these new chipsets coming out, I was unable to set the volume level in software and which you helped me work on a few months ago. I solved the issue, just increased the delay after the mp3.begin() in the setup from my 20ms to 1000 and now the volume is working again! Just wanted to share and say thank you for all your help too!

void setup() { Serial.begin(9600); mySerial.begin(9600); myMP3.begin(mySerial); delay(1000); myMP3.volume(SPEAKER_VOLUME); }

Thanks for sharing! What chipsets have you tested this with?

My pleasure! All MP3 DFplayers seem to work except the MP3-TF10P(something like that) labeled ones.

Hi, From library version 1.1.0 I have also added delay about 1000ms after begin() and it works well with many chips. And if this is new or not, In my case, if I call currentSdTrack with timeout 200ms(not default 100ms), the return value is -1. After I increase the threshold to respond to 500ms, then return value is valid. Actually I want to create new issue but I just post it here. Hope it will help another person who also use this amazing library. If you ask which chip? I have 8 different chips of it. From YX5200, GD3200B, MH2024K-24SS (24 pin), MH2024K-16SS (16 pin), and JL series (AC21xx, AA20xx, AS20xx, AA19xx) and not every chip has the same characteristics. Oh btw, some chips only works (even some chip not all command works) when there's no checksum in command(removing 2 bytes). most can process command with or without checksum. Thank you.
