Firstly, the utility refuses to access the DTP-94 with 'new_disprd failed with "Instrument Access Failed" ' when using the '-N' switch to avoid having to remove the eye-one from the screen every testing round.
OK, I'll change that to be a warning rather than an error.
Without using the '-N' switch the patches read, but the display window appears to hangrandomly with the spinning egg-timer replacement, resulting in 15 measurement of the same patch. When the reading does complete, attempting to save the matrix results in the program crashing immediately, with no file saved. Have you any suggestions for what I could be doing wrong? I did get it to work once when I got a chance to try it quickly on Wednesday, but could not reproduce the success. The file seemed valid and plausible.
I don't seem to be able to reproduce this problem (I'm assuming this is with the DTP94 rather than whatever spectrometer you were using ?), but then I don't have two displays on my Vista test box. You could try removing the USB driver and re-installing it from V1.3.0 (Device manager, Uninstall, "Delete driver software..", Scan for hardware changes, Update driver software, Browse my computer, Argyll_V1.3.0\libusb1, ...) I'm not sure how to reproduce the crash either. An alternative to using the interactive mode is to create a test chart (say "targen -v -d3 -f0 -e0 -m3 test"), measuring it using dispread with the two instruments, and then using ccmxmake -f file1.ti3,file2.ti3 etc...
On the more trivial matters, the ccmxmake -h text reads: 'usage: ccmxmake [-options] output.sp'. I presume this should read .ccmx?
Thanks. Graeme Gill.
