UEXT and MIDI
« on: September 15, 2012, 06:59:13 PM »
Does anyone know-
MOD-MP3 UEXT modules work with MIDI messages.
In chip VS1053 this is provided.
If yes, how to send MIDI data through UEXT
*

I creat  new MIDI instrument based on OLIMEXINO-STM32 .
It successfully working in with a computer or other external MIDI devices.
I would like to create a device that is autonomous.

Yes, I know about SHIELD-MIDI.
   My question is whether it is possible to send MIDI information inside to the MP MOD-chip VS1053 trougt uext? In order to play in his own internal MIDI synthesizer who works in General MIDI 1 mode, and the resulting audio output.

VS1053 is connected by SPI to UEXT so it may be possible but we never try this
VS1053 is programmable DSP there is SDK on VLSI web site which you can use to write your own code which to run on it

I have built a MIDI synthesizer on-chip VS1103 base.
http://www.instructables.com/id/VSS1103b-Standalone-MIDI-Synthesizer/step2/Schematic-diagram/
Midi signal was sent through the RX

And I want to do the same with the original Olimex mod-mp3 module.
Do Olimex MOD-MP3 module could be a significant difference?

May be, would suffice if connect a single wire to the RX input MOD-MP3 board with MIDI output?
 sorry, I'm not an expert

well done!
VS1103 and VS1053 are from same family you have to check the schematic for the necessary changes and give it a try
