ProsilicaIo module¶

Standard Scorpion python IO interface to Advantech Bionic Interface

Driver Version 1.1.0.13
ProsilicaIo.py = 1497

In the module there are three input/output classes for Prosilica GC750 camera:

* RS232 - serial communication via on board camera's serial port
* SyncIn - read sync input state
* SyncOut - control sync output state

1.0.0.1, 23nov2015, RL: std autodoc header
1.0.0.0, 25mar2012, RL: initial

Sample usage:

import ProsilicaIo
import time
try:
  cam = GetCamera('0')

  # Opens serial port on camera and return RS232 object
  rs232 = ProsilicaIo.open(cam, 115200, 8, ProsilicaIo.RS232.Parity.none, ProsilicaIo.RS232.StopBits.one)

  # Transmit string while ten symbols received
  while rs232.getRxLen() < 10:
        rs232.write("Hello world!\r\n")

  # Read received data and print
  print rs232.read()

  # Create object to read sync-in 1
  syncIn1 = ProsilicaIo.SyncIn(camera, 1)
  print syncIn1.IsSet()

  # Create object to control sync-out 2
  syncOut2 = ProsilicaIo.SyncOut(camera, 2)
  # Set high level on sync-out 2 for 1 second
  syncOut2.Set()
  time.sleep(1)
  syncOut2.Clear()

except Exception, msg:
  print msg

class ProsilicaIo.RS232(camera, baudRate=19200, dataBits=8, parity=0, stopBits=0)¶

Provides serial communication using camera on board RS232 port.

class Parity¶

none = 0¶

odd = 1¶

even = 2¶

class RS232.StopBits¶

one = 0¶

onePointFive = 1¶

two = 2¶

class RS232.ReceiveStatus¶

overrun = 1¶

framingError = 2¶

parityError = 4¶

clearAllErrors = 7¶

RS232.open()¶

opens serial port

RS232.close()¶

closes serial port

RS232.setup(baudRate=19200, dataBits=8, parity=0, stopBits=0)¶

set serial port parameters: baud rate, data bits, parity, stop bits

RS232.getRxLen()¶

returns count of bytes waiting in receive buffer

RS232.getRxStatus()¶

returns receive status: buffer overrun, framing error, parity error

RS232.clearRxErrors(clearMask=7)¶

Clears specified error bit in receive status.

RS232.read()¶

reads all data from receive buffer

RS232.write(data)¶

writes data in to transmit buffer and starts transmiting

ProsilicaIo.open(camera, baudRate=19200, dataBits=8, parity=0, stopBits=0)¶

class ProsilicaIo.SyncIn(camera, inputNo)¶

IsSet()¶

class ProsilicaIo.SyncOut(camera, outputNo, invert=False)¶

class SyncOutMode¶

AcquisitionTriggerReady = 'AcquisitionTriggerReady'¶

FrameTriggerReady = 'FrameTriggerReady'¶

FrameTrigger = 'FrameTrigger'¶

Exposing = 'Exposing'¶

FrameReadout = 'FrameReadout'¶

Imaging = 'Imaging'¶

SyncOut.Invert(invert)¶

SyncOut.IsSet()¶

SyncOut.SetMode(outputMode)¶
