Phatline Posted January 20, 2022 Report Posted January 20, 2022 (edited) 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. Edited January 21, 2022 by Phatline
Phatline Posted February 6, 2022 Author Report Posted February 6, 2022 (edited) 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 Edited February 11, 2022 by Phatline
Phatline Posted February 11, 2022 Author Report Posted February 11, 2022 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!
