Hi,
ResponderEliminarEverything about the final version is described here, including all the schematics and PCB design files: http://arduinosynth.blogspot.com.es/2012/09/codigo-fuente-y-memoria.html
But I'm afraid that almost everything is on Spanish.
Regards,
Jose
Thank you very much! Will take a look regardless of Spanish language that I do not know. I am looking at the scematics and I have 3 questions (for now):
Eliminar- Does this circuit supports Common Anode RGB LED Matrix 8x8 (like GTM2088ARGB-21)
- What is that opto coupler 6N138 used for?
- Could I get yours skype handle or email?
Sincerely,
Marko
-Yes, the circuit is for common anode RGB matrix.
Eliminar-The opto coupler is for the MIDI input. The MIDI specification defines a input stage that must be optocoupled, in order to add protection and remove the need to possibly adapt voltage levels.
-I prefer if you use the blog comments to ask, so everyone may see the possible questions about the project ;-)
