RIT owns several Photo Research telespectroradiometers that are used across several departments. The devices are primarily used as calibration and characterization tools for source spectral power distributions and other absolute radiometric readings. Currently, psychtoolbox is used through MATLAB to record data from these instruments. However, because this toolbox is only supported under 32-bit versions of MATLAB (which are being phased out on campus), options for recording are limited

These command-line tools were written to help facilitate recording spectral measurements with these devices. They take advantage of POSIX-standard serial communications, so should be compatible with most Mac and Linux machines.

Currently, they do not autodetect the serial (or serial emulation USB) port being used. This must be passed in as a command line argument.

The port can be found by using ls /dev/tty.* from a terminal window, then plugging in the device and repeating the command. The new device present is the proper serial port.

GCC is required to build the binaries with the current Makefile.

Running PR650Control or PR655Control with no arguments at the command line will display instructions for command line use of these tools. Further documentation will be supplied as it is written. In the meantime, feel free to contact me with any questions or concerns!
