ESP32 having two MIDI INs

[copych]

Hello, I'd like to have two MIDI IN ports on ESP32, using UART0 @115200 baud and UART2 @32150 baud simultaneously. I use MIDI_CREATE_CUSTOM_INSTANCE, and UART2 seems to work well, while UART0 gives errors in hairless midi log. Please, is there some working example?

This seems to work

#ifdef MIDI_VIA_SERIAL
  // default settings for Hairless midi is 115200 8-N-1
  struct CustomBaudRateSettings : public MIDI_NAMESPACE::DefaultSerialSettings {
    static const long BaudRate = 115200;
  };
  MIDI_NAMESPACE::SerialMIDI<HardwareSerial, CustomBaudRateSettings> serialMIDI(Serial);
  MIDI_NAMESPACE::MidiInterface<MIDI_NAMESPACE::SerialMIDI<HardwareSerial, CustomBaudRateSettings>> MIDI((MIDI_NAMESPACE::SerialMIDI<HardwareSerial, CustomBaudRateSettings>&)serialMIDI);
#endif

#ifdef MIDI_VIA_SERIAL2
  // MIDI port on UART2,   pins 16 (RX) and 17 (TX) prohibited, as they are used for PSRAM  
  struct Serial2MIDISettings : public midi::DefaultSettings{
    static const long BaudRate = 31250;
    static const int8_t RxPin  = MIDIRX_PIN;
    static const int8_t TxPin  = MIDITX_PIN; 
  };
  MIDI_NAMESPACE::SerialMIDI<HardwareSerial> Serial2MIDI2(Serial2);
  MIDI_NAMESPACE::MidiInterface<MIDI_NAMESPACE::SerialMIDI<HardwareSerial, Serial2MIDISettings>> MIDI2((MIDI_NAMESPACE::SerialMIDI<HardwareSerial, Serial2MIDISettings>&)Serial2MIDI2); 
#endif 

void setup() {
#ifdef MIDI_VIA_SERIAL
    Serial.begin(115200, SERIAL_8N1); 
#endif
#ifdef MIDI_VIA_SERIAL2
  pinMode( MIDIRX_PIN , INPUT_PULLDOWN);
  pinMode( MIDITX_PIN , OUTPUT); 
  Serial2.begin( 31250, SERIAL_8N1, MIDIRX_PIN, MIDITX_PIN );
#endif
}
