I have allready been there and seen that, but it shows that a connetcion have to be made to the PIC 25+26 pins >>> those are the SAME as the DIN !!!

should they both (DIN + COM) be connected to the same place ??

that is two lines going to the PICs 25+26

If I understand the question, you want to have MIDI in and Out Ports AND a COM port? I don’t think this is possible:

(only one driver is allowed for the Rx Input of the PIC, either the 6N138, or the MAX232, or a second Core module)

(from the LTC Module descrition page)

If you really need this, I think you would have to use another CORE as a MidiMerger. Hope this helps.

As an afterthought - if you need both, but not at the same time, you could make them both and then put a switch on pins 25 & 26 to choose which interface is active.

those were my thoughts too, but (although i dont understand a word of german) i have seen this done in the “midibox-plus-hardware-tutorial” by Heico .

it is clearly seen on his backside of the box, and it is also seen in the explanation

Heico just built an option into his box which enables him to connect the MIDIbox directly with the gameport without a MIDI interface. But he isn’t able to use both, the MIDI-In and the Gameport plug, at the same time.

Best Regards, Thorsten.
