I've been playing with the VS1053 module from LC (this one )

So far I've managed to get it playing back mp3, flac and wav files from SDcard with, of course, better audio quality than the native PicoMite audio.
In addition I've got it supporting real-time midi. i.e. you can send it the various midi instructions (note on, note off, channel, etc.) and it will interpret them. The chip supports a maximum polyphony of 64, and the maximum sustained polyphony is 40.
the instruments supported are as below.
If I can get the various wrinkles sorted out I will include full support for this board into the PicoMite firmware

Sounds great

Ideal for midi files in the background.
Next PicoMite board with this chip?

Newer datasheet.

Don't know if any significant differences compared to Martin's.

If anyone has got one of these here is some firmware to play with

PicoMite.zip

PLAY VS1053 XCSpin, XDCSpin, DREQpin, XRSTpin [, fname$ [,interrupt]]

NB: OPTION SYSTEM SPI must be set up and wired to the MISO, MOSI, and SCK pins on the module
NB: OPTION AUDIO does not need to be set to use the VS1053
NB: maximum CPU speed for this module is 252MHZ

modes of use:

File playback
PLAY VS1053 XCSpin, XDCSpin, DREQpin, XRSTpin , fname$ [,interrupt]
Plays the file fname$ in the background. This can be a FLAC, MP3, WAV or MIDI file.
NB: The MIDI file must be in format 0, i.e. all tracks interleaved.
Use the optional parameter interrupt to trigger an MMBasic interrupt when playback is complete.

Real time MIDI
PLAY VS1053 XCSpin, XDCSpin, DREQpin, XRSTpin
This opens the VS1053 in real time MIDI mode meaning it responds to MIDI commands. To support this use:

PLAY NOTE ON channel, note, velocity
PLAY NOTE OFF channel, note [,velocity]
PLAY CMD cmd, data1 [,data2]

Together these allow you to use all the channels, instruments and notes the VS1053 is capable off

Use PLAY STOP to exit this mode

Feedback appreciated

There's a version of these VS1053 boards with a line in jack and an SD card slot. Are these usable too?

Is microphone support possible?

Should work but no promises. The issue is that connections to the VS1053 I/O pins configure how it behaves on boot. My code overrides these default configurations but I can't guarantee that I've caught them all. Hopefully I have as the board I picture is known to have an unusual default configuration which I had to override to get it to play mp3 etc.

Lots of midi files posted seem to be the wrong format for the VS1053 so I've included a format conversion program in MMB4W. Uses too much memory to be included in the PicoMite.

Use

PLAY CONVERT fname1$,fname2$

Is the file in that zip supposed to be MMBasic.exp (that is, exp rather than exe)?

Hi Pete

I have the same configuration
MAKER PI PICO card
Pico 2040
sound card as your (gp9,gp8,gp7,gp6)
PicoMite MMBasic Version 5.07.08RC20
OPTION SYSTEM SPI GP10,GP11,GP12
OPTION SDCARD GP15

you wrote

NB: OPTION SYSTEM SPI must be set up and wired to the MISO, MOSI, and SCK pins on the module
NB: OPTION AUDIO does not need to be set to use the VS1053
NB: maximum CPU speed for this module is 252MHZ

for that I send midi command and I receive

> play vs1053 gp9,gp8,gp7,gp6
Error : Audio not enabled
>

if I put option audio, I receive that

> option audio spi gp9,gp6,gp7

From the referenced post

Quote Note that like the MCP4822 the VS1053 uses a separate SPI port from that specified by OPTION SYSTEM SPI. A dedicated SPI channel is essential to allow it to be used in a H/W interrupt routine.

Yes but this thread refers to an experimental test version. As always the final version will be in the release candidate thread and documented there.

Hi,

is it possible to start an MP3 file at a certain point or can the file only be started from the beginning?

It would be great to build an audiobook reader that can memorize the position in the MP3 file and play it back from that position after switching it on again.

Would that be possible?

Frank
