A look at how to control the DFPlayer Mini module and MP3-T-16P v 3.0 using an Arduino Uno, Mega 2560 and ESP32. All code and more details available at www.digitaltown...
Thank you for your introduction. I wanna extend my Arduino hardware to playback Beatles songs while Hornby Beatles train stops at station. Thanks again from Hong Kong.
I guess most of the people didn't understand that the communication method is UART and thr baud is 9600.. You are sending a lot of data and you need the receiving side to be with a big buffer. If you let the player execute the command sent end empty the buffer and use all the data sent to him all will be ok. That's it, just a lack of memory.. 😊 100 milliseconds between commands is more than enough.
I have bought several from different vendors, connecting via UART has been impossible. I’ve tested with multiple arduino libraries and micropython. Never works as intended. I’ve ordered what I hope is the original. Let’s see if it works…
The short answer is no because the unit doesn't seem to read file names the way we would normally think of them. It just seems to run through the order they have been put on the SD card... and with a unit this cheap that's not surprising. The only work around is to load your tracks on the SD card, play through them and list the order and then use an array to draw the file names from as the track plays. The problem with this is if you change the tracks you have to start again.
Sorry I've not tried clips that short, I think the shortest I've done is 3 seconds. Have you tried formatting the card and only putting that single clip on. Gragmentation of any kind on the card is always a problem.
@@ThePackingtapetech I The sound on the ones I have has been identical to my ears to the old version. I do wonder about the quality of them but at the price I pay what can I expect.
so many cheap versions out there and many different problems, even how the tracks are added on the sd card, the only way to guarantee no problems is order direct from DFROBOT , but at $6 each vs the cheaper alternatives, I guess depends on budget and if that budget is worth the stress.
