Luxbeam Introduction

Build Documentation HTML

Luxbeam is a python package that implements the protocol for programming Luxbeam DMD controller from VISITECH. The Luxbeam class implements the control protocol of Luxbeam digital micro-mirror device (DMD) controller. This is tested with Luxbeam 4600 controller and DLP9500UV DMD. In addition to equipment control from the Luxbeam class, the LuxbeamSeqeuncer class implements the support for composing sequencer code used in Luxbeam controller. This allows the user to compose the sequencer code using native python arithmetic operations and some of the flow controls.

Installation

Luxbeam can be installed from PyPI via:

pip install Luxbeam

One can also clone the repository to install it in the develop mode:

pip install -e .

Test

It is recommended to run the test cases to ensure LuxBeam is compatiable with your setup.

Run the tests in the test folder:

pytest test --ip="<IP address>"

Run the interactive tests:

pytest test --ip="<IP address>" --interactive -s

Example

import Luxbeam
from Luxbeam.sample import number_image

#  This is the equivalent example of displaying non-scrolling images in the LB 4600 user guide.

# Connect to the Luxbeam
luxbeam = Luxbeam.Luxbeam("192.168.0.10", timeout=1)  # modify the ip address if required.

# Prepare the image (display 123 on the DMD)
image = number_image(123, luxbeam.cols, luxbeam.rows)

# Set image type to 1 (binary). (One-time Operation)
luxbeam.set_image_type(1)

# Set inum size to 1080. (One-time Operation)
luxbeam.set_inum_size(luxbeam.rows)

# Disable the sequencer.
luxbeam.set_sequencer_state(Luxbeam.SEQ_CMD_RUN, Luxbeam.DISABLE)

# Set sequencer in reset-state
luxbeam.set_sequencer_state(Luxbeam.SEQ_CMD_RESET, Luxbeam.ENABLE)

# Load the image to inum = 0.
luxbeam.load_image(0, image)

# Compose the sequencer file.
seq = Luxbeam.LuxbeamSequencer()
for _ in seq.jump_loop_iter():  # A while-true loop
    seq.load_global(0, 400)  # Load data from Inum (0) to DMD
    seq.trig(Luxbeam.TRIG_MODE_NEGATIVE_EDGE, Luxbeam.TRIG_SOURCE_INTERNAL, 0)  # Neg. edge internal trigger
    seq.reset_global(40)  # Display contents on DMD

# View the generated sequence file
print(seq.dumps())

# Send sequence file.
luxbeam.load_sequence(seq.dumps())

# Take sequencer out of reset-state
luxbeam.set_sequencer_state(Luxbeam.SEQ_CMD_RESET, Luxbeam.DISABLE)

# Start the sequencer
luxbeam.set_sequencer_state(Luxbeam.SEQ_CMD_RUN, Luxbeam.ENABLE)
