Made a wiki Euro-Midi-IO
Frontpanel and PCBs are ordered -l now wait for the prototype
can someone check the shematic - i may overlooked something:
Thx.
quick update… i debugged Rev.A with a view Wires
(and it works - almost),
by doing this i made Rev.B - and updatet the wiki.
For Rev. B i have to Cross J1 to J2, since i made a 1:1 Connection between this 2 Headers… - and that is not true… true would be:
I2>I4, I4>I2, O2>O4… and so on
I tryd this Variant for Midi-OUT Activity LEDs… as it works with NoteON-OFF Messages, it comes to its limits when transfairing high datarate - like midiclock. The steady Charge and discharge of C5, messes up the Datasignal, so it cant be used.
Since i already used all Pins of 74HC14, i now need a second HC14, or some other Buffercircuit (for 2x Midi-OUT Activity LED) - any Ideas for that are welcome!
