- You Reply: 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.
Regards,
Björn - You Reply: No, that wasn't the problem. Still blinking, with both cards.
- You Reply: 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.
