DFRduino Player keeps blinking
bjoerngiesler 2012-06-06 11:08:49 5100 Views8 Replies Hi,
can someone please help me? I'm going crazy. I have a DFRduino player here, also 2 different µSD (not SDHC) cards, in 1GB (Kingston) and 2GB (SanDisk). I've FAT-formatted both of them again and again, and after seeing the junk dotfiles MacOS puts on the card, I've made sure to format the cards on PC. So now they contain just 3 MP3 files following 8.3 convention, named "test.mp3", "yes.mp3" and "no.mp3".
Still the player just keeps on blinking after power-up, which according to the manual means it can't read the SD card. Can someone tell me what to do to the card to get the player to recognize it?
Thanks a lot,
Björn

bjoerngiesler 2012-06-13 01:33:42 Hi,
looking at the player source, it seems that the player will only work if:
[list]
[*]there is a directory named "sound" in the root of the card
[*]that directory contains files ending in "wma", "wav", "mid" or "mp3"
[/list]
So the blinking light signals not only problems reading the card, but it will also blink if there is no "\sound" or if there are no playable files in that directory. I'm pretty sure that my card doesn't have that structure (I'm currently at work and can't look), so that may be the problem.
Looking at the Wiki, the subdirectory is actually mentioned, but only as an aside in the sample section. It would be a really good idea to put that in the "Support SD Card" section. Right now, that section states "If the green led do not flash, it means the SD card is working properly", and that is very misleading.

bjoerngiesler 2012-06-08 19:03:51 Hi Bjorn,
Did you buy the player directly from us? I think the player might be faulty. Generally Kingston or SanDisk are acceptable cards for this player. We have discontinued the player because we have found some issues with it. We are redesigning it and we will release a new player when we have managed to remove all the bugs.
If you bought the player directly from us please send me an email to techsupport AT dfrobot DOT com
and provide your order number. If you did not buy it from us, still write me an email and we will see about getting you a tested functioning player replacement.

Do you have a DC supply you can connect to the arduino, anything between 6 to 9 volts would be good.
Sometimes the USB cable will not supply enough power to the Arduino to support other connected devices.

Hector 2012-06-06 21:23:54 Sure. I'm connecting it to the Arduino as shown in the Wiki -- +5V and GND, Analog 4&5 pins all from the Arduino. The Arduino itself is powered by the USB cable from the PC. bjoerngiesler
bjoerngiesler 2012-06-06 19:51:57 Hi Bjorn,
How are you providing power to the player? who are you connecting it? Are you using an Arduino?
