YX5300 connected to Giga R1

Projects Programming

Hello,

I have uploaded the code below and get no errors.

When I push the play button there is no sound from the mp3 on the sd-card.

The tracks are named 001.mp3, 002.mp3 and 003.mp3 and are in the root of the sd-card.

The connections are: RX of YX5300 to TX (pin 1) and TX of YX5300 to RX(pin 0).

When I monitor the packet it looks oké.

Set volume at 20.

Packet: 0x7E 0xFF 0x06 0x06 0x00 0x00 0x14 0xEF

Play with index

Packet: 0x7E 0xFF 0x06 0x03 0x00 0x00 0x01 0xEF

Next track

Packet: 0x7E 0xFF 0x06 0x03 0x00 0x00 0x02 0xEF

Stop playing

Packet: 0x7E 0xFF 0x06 0x16 0x00 0x00 0x00 0xEF

joined ground ?

Giga R1 is a 3.3V device, what about your YX5300?

3

It is connected to gnd and 5V of the Giga and de red led on the yx5300 is on.

4

Is your YX5300 a 5V or a 3.3V device ? (What voltage will be set on its Tx if the module sends a 1 ?)

5

The voltage on Tx is 3.1V.

6

I found the problem.

I connected the Tx → Rx and Rx → Tx.

That didn’t work and after seeing some pictures of the YX5300 board I saw that the lables on my board were different than on the pictures.

So I chanced the connections (Tx → Tx, Rx → Rx) and now my board is working like it should.

thanks for sharing the solution
