      <TD CLASS=TABCOLOR2>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).<BR>

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.<BR>

MIDI OUT4 will be available on the J5B.SA pin, it isn't required to remove R11 if already soldered - it doesn't hurt.

Note also that in difference to the MBHP_CORE_STM32 module, the J15 ports have been rotated by 180 degrees! But the polarity is the same, which means that you can re-use the LCD cables which you made for the MBHP_CORE_STM32 module.<BR>
