Python camera control using MicroManager device drivers
Raw
python_camera_micromanager.py
# This python code uses MicroManager device drivers to control a camera.
# Tested on Hamamatsu Orca Flash 4 camera, should work similarly on other cameras.
# Original idea: Kay Schink @koschink
# Gist implementation: Nikita Vladimirov @nvladimus
#Environment setup instructions: https://micro-manager.org/wiki/Using_the_Micro-Manager_python_library

import matplotlib.pyplot as plt
#load camera and set it up

mmc.getVersionInfo()
mmc.loadDevice('Camera', 'HamamatsuHam', 'HamamatsuHam_DCAM')
mmc.initializeAllDevices()
mmc.setCameraDevice('Camera')
#Optional block: set an output trigger for synchronization with other devices
#mmc.getDevicePropertyNames('Camera') #execute if forgot prop names
#mmc.getProperty('Camera','OUTPUT TRIGGER PERIOD UNITS') #seconds
#mmc.getAllowedPropertyValues('Camera','OUTPUT TRIGGER KIND[0]') #check what's allowed

plt.imshow(img, cmap='gray')
# pretty image should be displayed here
mmc.reset() #say good bye
