serial

Provides methods for working with serial ports.

getBuffer

Return data buffer.

Returns:

CircularStringBuffer - Data buffer.

list

Returns list of available ports.

See https://github.com/EmergingTechnologyAdvisors/node-serialport#module_serialport--SerialPort.list for details about the structure of returned values.

Returns:

Array.<Object> - Array of port descriptions.

open

Opens a serial port.

Data from the opened port will be automatically read line by line into a circular buffer. Once the buffer reaches it's maximum capacity specified by bufferSize argument, eldest entries are evicted to make room for new data.

** Serial port properties with default values:**

{
 baudRate: 9600,
 dataBits: 8,        // Must be one of: 8, 7, 6, or 5.
 stopBits: 1,        // Must be one of: 1 or 2.
 parity: 'none'      // Must be one of: 'none', 'even', 'mark', 'odd', 'space'.
 rtscts: false,
 xon: false,
 xoff: false,
 xany: false
}

Parameters:

NameTypeDescription

String

Path to serial port. E.g. '/dev/tty-usbserial1', 'COM5', etc.

opts

Object

Port properties.

bufferSize

Number

optional Size of the input data buffer. Default is 65536 bytes.

Returns:

SerialPort - SerialPort object.

waitForText

Waits for text to appear in the input data buffer.

Text pattern can be any of the supported string matching patterns(on the top of page).

Parameters:

NameTypeDescription

pattern

String

Text pattern.

timeout
