Overview

Wasatch.PY is a Python application-level driver for Wasatch Photonics spectrometers. It has been tested on Windows, Linux and MacOS platforms, and is directly used by Wasatch's own ENLIGHTEN™ spectroscopy desktop GUI.

If you'd like simpler, smaller examples of how to perform individual operations against Wasatch spectrometers from Python, please also see our Python Example Scripts repository.

History

This project can be viewed as a conceptual successor to the earlier WasatchUSB. The main differences are that while WasatchUSB was a copy-paste of key ENLIGHTEN functionality, Wasatch.PY literally is a dependency of ENLIGHTEN. As a result, when we fix or add ENLIGHTEN features, Wasatch.PY will be updated by necessity; making the same foundational interface available to all our users.

WasatchUSB, in contrast, had the potential to drift out-of-sync with ENLIGHTEN internals, such that customers and company might experience different results.
This new shared library exemplifies one of our core values: all about dogfooding!

Finally, the updated project name reflects the fact that this is specifically a Python binding and implementation; for other USB-capable interfaces, see our WasatchUSB or upcoming Wasatch.CPP libraries!

API

Until we draft proper API documentation, these are the standard settings which can be passed to device.change_setting(). Booleans should be passed with an argument of 1 (enable) or 0 (disable).

"laser_enable" (bool)
"integration" (int (milliseconds))
"detector_tec_setpoint_degC" (int)
"detector_tec_enable" (bool)
"degC_to_dac_coeffs" (string of 3 space-delimited floats, e.g. "1.1 2.2 3.3")
"laser_power_perc" (int, 0 to 100 inclusive)
"laser_temperature_setpoint_raw" (int, 0 to 127 inclusive)
"ccd_gain" (float)
"high_gain_mode_enable" (bool)
"ccd_trigger" (bool)
"scans_to_average" (int, 0 or 1 to disable)
"bad_pixel_mode" (wasatch.common.bad_pixel_mode_none or _average))
"log_level" (int, see Python logging levels)

Note that there are many more functions available in fid_hardware.py and sp_hardware.py (via devices.hardware) but these are not yet fully documented.

Dependencies

Wasatch.PY uses the Python 2.7 build of Miniconda for dependencies and package management.

Running the Demo

Following are the general usage instructions for the included command-line demo scripts. After find specific Anaconda setup instructions for Windows, MacOS and other tested platforms.

usage: demo.py [-h] [-l LOG_LEVEL] [-o BUS_ORDER] [-i INTEGRATION_TIME_MS]
			   [-s SCANS_TO_AVERAGE] [-w BOXCAR_HALF_WIDTH] [-d DELAY_MS]
			   [-f OUTFILE] [-m MAX] [-b]

Simple demo to acquire spectra from command-line interface

optional arguments:
  -h, --help            show this help message and exit
  -l LOG_LEVEL, --log-level LOG_LEVEL
						logging level [DEBUG,INFO,WARNING,ERROR,CRITICAL]
  -o BUS_ORDER, --bus-order BUS_ORDER
						usb device ordinal to connect
  -i INTEGRATION_TIME_MS, --integration-time-ms INTEGRATION_TIME_MS
						integration time (ms, default 10)
  -s SCANS_TO_AVERAGE, --scans-to-average SCANS_TO_AVERAGE
						scans to average (default 1)
  -w BOXCAR_HALF_WIDTH, --boxcar-half-width BOXCAR_HALF_WIDTH
						boxcar half-width (default 0)
  -d DELAY_MS, --delay-ms DELAY_MS
						delay between integrations (ms, default 1000)
  -f OUTFILE, --outfile OUTFILE
						output filename (e.g. path/to/spectra.csv)
  -m MAX, --max MAX     max spectra to acquire (default 0, unlimited)
  -b, --non-blocking    non-blocking USB interface

Microsoft Windows

The following session was run on Windows 10 using the Cmd shell of Git for Windows and Miniconda (Python 2.7):

Linux

IMPORTANT: For Linux, you must copy the file udev/10-wasatch.rules from the Wasatch.PY distribution to /etc/udev/rules.d, then HUP udev or reboot. This will require root (sudo) privs, and is required to give userland applications access to USB devices matching Wasatch VID/PID.

Known Issues

Non-Blocking doesn't work on MacOS

MacOS doesn't allow usb.core.find() to be called from a forked background process. This is the error message you get:

"The process has forked and you cannot use this CoreFoundation functionality 
 safely. You MUST exec()."

It probably traces back to this:

https://discussions.apple.com/message/5829688#message5829688

Will investigate workarounds pending prioritization, but since the default blocking mode works, this shouldn't be a major problem until we port ENLIGHTEN to MacOS.

Common Errors

LIBUSB error: No backend available (MacOS)

Using Homebrew, type:

$ brew install libusb
