This denotes that a serial device is 15 dedicated to MIDI communication, either to an external MIDI device through a DIN5 16 or other connector, or to a known hardwired MIDI controller. This device must be a 17 child node of a serial node. 18 19 Can only be set to use standard baud rates corresponding to supported rates of the 20 parent serial device. If the standard MIDI baud of 31.25 kBaud is needed 21 (as would be the case if interfacing with arbitrary external MIDI devices), 22 configure the clocks of the parent serial device so that a requested baud of 38.4 kBaud 23 resuts in the standard MIDI baud rate, and set the 'current-speed' property to 38400 (default) 24 25properties: 26 compatible: 27 const: serial-midi 28 29 current-speed: 30 description: Baudrate to set the serial port to when this MIDI device is opened. 31 default: 38400 32 33required: 34 - compatible 35 36additionalProperties: false 37 38examples: 39 - | 40 serial { 41 midi { 42 compatible = "serial-midi"; 43 }; 44 }; 45 - | 46 serial { 47 midi { 48 compatible = "serial-midi"; 49 current-speed = <115200>; 50 }; 51 }; 52
