Hi Bianchi, unfortunately it seems that the board doesn't allow send private message. In the "Contact bianchi" portlet no button or object appear.
Maybe I don't know the exact procedure to do that.

Thanks.

Hi!

That's right, this is a public forum. We don't use private messages here because we want everybody to be able to benefit from solving problems here. When a problem is solved here, we want everybody to be able see the answer.

Hi Panu at the moment I don't need to submit a particular problem, but maybe in the future. I'm currently working on a project using the VS1053 and a STM32 board nucleo 152 LE.

It would be nice for me to share fiendship with another member interested in VLSI product and STM32 microcontroller. And this forum would be useful also for that in my opinion :-).

If this is not a problem I try to share my email for bianchi: dario.vicenzo74"at"gmail.com

I hope this doesn't hurt the forum administrators.

Thanks.

Hi Panu

I've been trying to get the hello.mp3 file to play - I have a PIC24F with the VS1063a. I was able to get the sine test to work, but, no such luck with this audible. What is the right value for CLOCKF that I should use? I have a 12.288Mhz xtal on the VS1063. Looks like people who have posted code here seem to have got the audible to work with different values for CLOCKF - Im not sure I see a pattern here. For some values, I hear a clipped sound, but hear nothing for others. I havent quite got my head around how to arrive at the right number to get this file to work. I'd appreciate your input.

Thanks!

The hello should be low enough bitrate (and mono) so it should play with the default 1.0x clock. SCI_CLOCKF should not matter, so the issue is probably elsewhere - like DREQ or chip select handling, SPI clock speed, or just some program logic (byte order, sending the correct number of bytes from the correct location in the array).

Hi,

I’m trying to play the “Hello” mp3 using a PIC24 and a VS1053b integrated in the Adafruit “VS1053 Breakout”.
Playing the Hello following the code posted in the first page of this thread results in random sound outputs. It is like the SV1053 is not been “done” with the decoding and the next bytes overwrite the old ones, resulting in some kind of broken “Hello”: for example a fraction of the word Hello with a ‘pip’ ( “Hel” plus “pip”), etc.

If I use the PIC24-Hardware SPI the distortion gets worse. I tested the code using more PIC24s and Breakouts having the same results.

[Please note that the Adafruit VS1053 shared the SPI with a SDCARD]

Hi, almen_80!

Check that your microcontroller obeys the DREQ signal: short circuit it low and check that your MCU really stops sending the data.

Hi Panu,

DREQ is defined low at start. I put a 2 seconds delay after sending the Hello but the chip is still unable to play the whole data or is playing it wrong.


Are there other registers that could help checking the state of the chip?
