Mini Lector de MP3 DFPlayer

Ceux-ci sont vraiment faciles à utiliser en tant qu'appareil autonome utilisant les broches IO ou le système ADKEY et peuvent également être contrôlés avec un microcontrôleur. J'ai trouvé des fonctions mal étiquetées sur les broches IO1 et IO2 (vol +/- prev/next) dans le manuel, planche à pain d'abord pour confirmer. Pour 2 des 3 projets pour lesquels je les ai utilisés, je n'ai pas eu besoin d'un microcontrôleur, l'utilisation d'un microcontrôleur était plus difficile. Je pense que la plupart des gens pourront consulter le manuel et se faire une idée de la mesure dans laquelle leurs compétences seront adaptées pour combiner cela avec un microcontrôleur.

The player is great but the documentation is terrible. Found a similar product with the same pin outs and commands and was able to get this product working with the documentation from the other product on my Parallax Propeller. I may submit an Object in the OBEX for it.

These are really easy to work with as a stand alone device using either the IO pins or the ADKEY system and can also be controlled with a microcontroller. I did find some mislabeled functions on pins IO1&IO2 (vol +/- prev/next) in the manual, breadboard this first to confirm. For 2 out of 3 of the projects that I've used these for I haven't needed a microcontroller, using a microcontroller was more challenging. I figure that most folk will be able to look at the manual and get an idea of how well their skills will be suited to combining this with a microcontroller.

wow .. that's a great little player for just $11.00. Once you get past the hieroglyphic manual, and the outright errors in the checksum calculations in their examples, it works beautifully. Clean, quality audio....again only $11.00....wow. Would have been 5 stars except for the manual

Documentation is missing some information and was wrong in some areas! Use SDFormatter app, not the format provided by Windows, to format an SD card. The player itself works well after a few google searches for example code.
