This Python package (mightex_device) creates a class named MightexDevice, which contains an instance of serial_device2.SerialDevice and adds methods to it to interface to Mightex LED controllers.

Example Usage

from mightex_device import MightexDevice
dev = MightexDevice() # Might automatically find device if one available
# if it is not found automatically, specify port directly
dev = MightexDevice(port='/dev/ttyUSB0') # Linux
dev = MightexDevice(port='/dev/tty.usbmodem262471') # Mac OS X
dev = MightexDevice(port='COM3') # Windows
dev.get_serial_number()
'04-150824-007'
dev.get_channel_count()
4
channel = 0 # channel numbering starts at 0, not 1!
dev.get_mode(channel)
'disable'
dev.set_normal_parameters(channel,1000,30)
dev.get_normal_parameters(channel)
{'current': 30, 'current_max': 1000}
dev.set_mode_normal(channel)
dev.get_load_voltage(channel)
2622
dev.set_normal_current(channel,200)
dev.get_load_voltage(channel)

dev.set_mode_disable(channel)
dev.set_strobe_parameters(channel,100,1)
dev.get_strobe_parameters(channel)

from mightex_device import MightexDevices
devs = MightexDevices()  # Might automatically find all available devices
# if they are not found automatically, specify ports to use

Installation

https://github.com/janelia-python/python_setup

• Set controller to RS-232 mode.
• Use DB-9 serial port cable to connect controller to host computer with a USB to Serial Port RS-232 Converter. Install drivers for USB to Serial Port RS-232 Converter if necessary.

Linux and Mac OS X

mkdir -p ~/virtualenvs/mightex_device
virtualenv ~/virtualenvs/mightex_device
source ~/virtualenvs/mightex_device/bin/activate
pip install mightex_device

Windows

virtualenv C:\virtualenvs\mightex_device
C:\virtualenvs\mightex_device\Scripts\activate
