USER Serial Port

This module allows you to open a serial port on your machine to communicate with hardware devices over a serial protocol.

Can be used to communicate with an Arduino.

Lets you receive in a text string format (ASCII ) and send values (text strings, array and MIDI/firmdata).

how to know my serial port number

If you need to know your device serial port number to use this module:

  • Windows: Check the device manager/port(COM & LPT)/

    You'll see something like: COM1, COM2,... This is the address of your serial port

  • Mac OSX: Open a terminal and type: ls /dev/tty copy the line you'll see, example: dev/tty.usbmodem1a1341

port

Sets here the port used by your serial device.

baudrate

Data transmission rate (bits/second), must be the same than your serial device (in your Arduino code for example). Tested with standard baudrates 9600, 57600, 115200.

rx buffer size

2 modes:

  • When > 0: Data Buffer size, up to 64 bytes (Each byte is composed of 8 bit character string).
  • When 0, switch to delimiter mode.

rx byte delimiter

Determines the delimiter value: when this value is reached your buffer is stored (in a circular loop similar to the circular record mode of the sampler)

on

Connect the module to the serial port

must be switched twice.

connected

Confirm the connection.

tx data (string)

Used to send 8-bit character strings data to the serial port,

tx data (array)

Used to send array data to the serial port.

Values cell values must be in the range of 0-255.

tx data (MIDI firmata)

Used to send MIDI/Firmdata to the serial port. Takes an incoming MIDI message and send it as a 3 bytes message without the channel information over the serial port. The channel information is ignored. This is a special format for the FIRMATA protocol.

clear rx buffer

Clear the buffer, useful, for example, when you turn the module OFF, then ON again

rx data

Data output.

rx buffer overflow

Indicates a data overflow.

saved in preset

Determines if parameters of this object are saved in the preset-panel.

fade preset

Parameters of the this object can cross faded when you recall a preset in the grid.

Optional setting, does not appear on all objects.

protocol

For experts: serial protocol used.

  • Parity
  • Char size
  • Stop bits

trace

level

Trace in the Usine console for debugging:

  • info: show only last action
  • debug: show only errors
  • verbose: show all
