GE Device

Connect and request Subrecord and Waveform:

device = GEDevice()
device.connect('/dev/ttyUSB0')

device.request(subtype=device.DISPL, waveform_set=['PLETH', 'ECG1'])

device.collect(True)

To clear the buffer input:

device.clear_buffer()

To stop the data collecting:

device.collect(False)

class pycollect.device.FakeDevice(raw_file)

Bases: object

Debugger class for simulate the input data.

__init__(raw_file)

Establish the connection and handle the data input from monitor.

Parameters:raw_file (str, optional) – Input file with raw data.

__read_raw__()

Return generator with the input raw data.

Returns:Generator for single bytes. Return type:Generator

close()

Close the serial port.

connect(port, timeout)

Establish the connection and debug an unrelated serial device.

Parameters:

• port (str) – Serial port.
• timeout (integer) – Timeout for serial comunication.

read(size)

Return the input raw file one byte at time.

Parameters:size (int) – Buffer input size to read. Returns:Array with raw data. Return type:list

writable()

Check if serial port is writable..

Returns:Port writable. Return type:bool

write(data)

Write on serial port if available.

Parameters:data (bytes) – Desired object to write in serial port.

class pycollect.device.GEDevice(raw_file=None)

Bases: object

Establish the connection and handle the data input from monitor.

__init__(raw_file=None)

Establish the connection and handle the data input from monitor.

Parameters:raw_file (str, optional) – Read from local file, no serial.

clear_buffer()

Crear the data buffer, not the serial input buffer.

close()

Close serial port

collect(flag=True, size=4096)

Enable or disable the continuous data reading.

Parameters:

• flag (bool, True) – Enable or disable the continuous data reading.
• size (integer, 2**12) – Input buffer size.

connect(port, timeout=1)

Establish the connection with the CARESCAPE Monitor Bx50.

• Baudrate: 19200
• Parity: even
• Stop bits: 1
• bytesize: 8 bits
• rtscts: True

Parameters:

• port (str) – Serial port address.
• timeout (int, in secods) – Serial port read and write timeout.

create_waveform_set(waveform_set)

Generate Waveform set.

Parameters:waveform_set (array) – List of waveform types. Returns:A list of integer that represent the waveforms desired. Return type:list

on_connection_loss()

Overwritable method.

read(size=4096)

Write into the data buffer the bytes readed from serial port.

Parameters:size (integer, 2**12) – Input buffer size.

request(subtype=None, waveform_set=None, interval=1)

Create and send a data request of Subrecord or/and Waveform type.

Parameters:

• subtype (subrecord type object) – DISPL, TREND_10S or TREND_60S
• waveform_set (array) – List of waveform types.
• interval (int, in seconds) – If subtype is DISPL interval is accepted and must be an integer equal or greater to 1.

request_multiple_wave_transfer(wave_set, transmission_type)

Create and send header of Waveform type.

Parameters:

• wave_set (array) – List of constants that represents each waveform type requested, if list lenghth is less than 8, the last integer must be 255.
• transmission_type (transmission type object) – WF_REQ_CONT_START for start start transmission, WF_REQ_CONT_STOP for stop it and WF_REQ_TIMED_START for request a timed transmission.

request_transfer(subtype, interval)

Create and send header of Subrecord type.

Parameters:

• subtype (subrecord type object) – DISPL, TREND_10S or TREND_60S
• interval (int, in seconds) – If subtype is DISPL interval is accepted and must be an integer equal or greater to 5

stop()

Send the request for stop the Subrecords and Waveform transmission.

stop_transfer()

Send the request for stop the Subrecords transmission.

stop_wave_transfer()

Send the request for stop the Waveform transmission.

write_buffer(data)

Check if device is writeble and send the data.

Parameters:data (bytes array) – Bytes with the header that bust sent to the device.
