serial
Provides methods for working with serial ports.
Return data buffer.
Returns:
CircularStringBuffer - Data buffer.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.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:
Name | Type | Description |
|---|---|---|
port | 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.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:
Name | Type | Description |
|---|---|---|
pattern | String | Text pattern. |
timeout | Number | optional Timeout in milliseconds. Default is 60 seconds. |
Write data to the port.
** Usage example:**
serial.write('Hello\r\n');
Parameters:
Name | Type | Description |
|---|---|---|
data | String|Array | Data to send. Either a string or an array of bytes. |
