I'm gonna send you a track. This is the most awesomest idea ever smile

Ok, I measured and swapped the bottom left and top middle pins of the GB cable and also figured that I did something wrong with me MIDI Out port (also swapped).

The schematic shows, in fact, the gameboy-end side of the cable.


Since it's my little monster, I may scream: IT LIIIIVES !!!! GWAHAHA!

Thank you very much, shizcake! smile

Yes, that's the schematic I'm working from. Thanks for the hint! I will post my results later.

Thanks for the replies.
Of course I set the sync mode to Midi Out. Ardiunoboy software is 1.2.3 (the newest one, I think)

My circuit is a little bit like Frankenstein's monster because I wanted to test everything before thinking about how to put everything inside a box, so I hope the annotations are helpful. There are no short circuits or loose connections. I tried to change the sides of the pins of the MIDI ports - I have no clue which way they have to go (the schematic is not very good at describing the MIDI pins).

Overview:

I guess you can't see very much here, but I uploaded it just for a overview of that beauty.

GB cable:

This is a part of the four-player-link-adapter thing. It was too hard to desolder it so I destroyed the PCB. The pins on the top layer are those of the flat side, the pins on the bottom are those of the shaped side of the plug.

Midi-In:

Midi-Out:

The 2K Ohm resistor that goes to the GND pin of the MIDI-Out is the pulldown resistor of the button. The 220 Ohm resistor goes to +5V.

Hey guys, nice to meet you.

I wanted to try out the MIDI-out function of LSDJ 4.7.3 (arduinoboy version) and built an Arduinoboy (using an Arduino Uno SMD Edition) so that I can hook it up to a SammichSID and a Korg Electribe.
The probem is: I don't get any MIDI signals.
I have checked the pinouts of the MIDI socket and the GB cable and LSDJ is playing some notes with Q commands.
Do you have an idea what I could possibly have done wrong? Or some common mistakes that I may have overseen?
As I don't need the MIDI-in I left that whole part away from the build (i.e. pins RX and 4 are not used) - could that be a problem?

Thank you very much.

//edit:
I added the MIDI-in so that I can look if I can connect via MAX. The Midi-in seems to work (as the status LED is flashing when I try to connect). But for whatever reason there is still nothing coming from the Midi-out sad
