Split topic: oneTesla MIDI interrupter

[Laci]

I would like to try out this interrupter Can you please tell me some informations about your interrupter?Can it play songs from SD card or has it got MIDI input?Do you have a schematic about it?

[futurist]

It can play .omd songs from SD card and also has a MIDI input

Here you can find firmware, schematics and MIDI > .omd converter

You can build one easily using atmega328p board, 16x2 LCD and SD card breakout board. Just connect everything and flash the firmware

I can't see the 4050  IC in your picture.Is it necessary?

[futurist]

I removed part of the code for SD card reader because I don't use it
If you're going to use SD card you need that IC and 3.3V regulator. It's non-inverting buffer which converts 5V atmega328p logic to 3.3V needed for SD card

I made it and it is working.Do you know how to convert MIDI files to OMD?

[futurist]

OMD converter
http://onetesla.com/media/omdconvert.exe

[Laci]

Already downloaded it,but when I run it,the command line flashes,and turns off.If I open the omdconvert.exe in command line,it shows the "usage",the "arguments" and I can't continue the program,because the cmd starts a new command.

In the onetesla firmware the README file shows that Visual Studio or GCE should be used.Is this a possible problem because I don't have the Visual Studio IDE installed?

[Mads Barnkob]

I got visual studio tools installed, not sure if that is required, but if their readme says to have it, it doesn't hurt to try.

Here is my command prompt just running the program

Code: [Select]

D:\sync\Dokumenter\Højspænding\Midi\Midi til Tesla coil\Tesla coil midi>omdconvert
Usage: omdconv.exe <file name> [arguments]
Arguments:
-v: verbose mode
Her I supply a midi file to convert and a read_m.omd files appears in the folder afterwards.

Code: [Select]

D:\sync\Dokumenter\Højspænding\Midi\Midi til Tesla coil\Tesla coil midi>omdconvert read_m.mid

D:\sync\Dokumenter\Højspænding\Midi\Midi til Tesla coil\Tesla coil midi>

Best way to use it:  make a desktop shortcut to the omdconvert.exe.
Then just drag and drop midi files to the shortcut; the omd will end up in same directory as midi file.

Thank you very much Garyf!I tried everything but I could not get it to work.This does the trick.
