MIDI Quad IIc connection to MBHP_CORE_LPC17

[cosmosuave]

More questions arise as I am completing my SEQV4 after looking at the documentation I am trying to figure out which jumper connection on MBHP_CORE_LPC17 does the MIDI Quad IIc connect to? I need to get the right connectors for this.. Is it J4B on the core or pins on J5B or a combination of both?

 

Thanks...

The LPC17 Documentation says:
 

 

J4A IIC port. Interface to BankSticks or to MBHP_IIC_* modules like MBHP_IIC_MIDI.

 

 

J4B A second IIC port, which can also be used as an additional MIDI IN/OUT port (MIDI IN4/OUT4) if enabled in MIOS32 (add "#define MIOS32_UART_NUM 4" to the mios32_config.h file).

MIDI IN4 will be available on the J4B.SC. If a 6N138 based optocoupler circuit should be connected, replace the 2.2k pull-up R10 by 1k, or add a second 2.2k in parallel to get 1.1k effectively.
MIDI OUT4 will be available on the J4B.SD pin, it isn't required to remove R9 if already soldered - it doesn't hurt.

 

 

So either J4A or if that one in use then you can use J4B.

J4B it is then...

 

Thank you...
