If i want to connect a core module to a midimerger module, can i simply leave of the second optocoupler and directly attach J11 Midi Out from the core to RA4 of the pic16f877 midimerger?
The info on the core page seems to suggest this, but since it’s not explicitly given as an example I figured I would ask.
Thanks in advance.
Yes, it should work as long as devices share the same PSU ground.. And I’m not sure If that 1.2K pullup resistor in the midi input is actually needed if optocoupler is omitted?!
Bye, MOebius
The 1.2k pull-up doesn’t hurt (it isn’t required so long you don’t plan to disconnect the MIDI Out driver during runtime)
Best Regards, Thorsten.
