I am hooking something that uses PTB in polling mode, and I can't call the Mon, 23 Nov 2009 20:50:46 GMT xrli2002 http://tech.groups.yahoo.com/group/psychtoolbox/message/10320 http://tech.groups.yahoo.com/group/psychtoolbox/message/10320 You could do this way: tOffset=now*24*3600-GetSecs; % offset between now and GetSecs myTime=datenum(V)-tOffset; % convert date vector V into GetSecs time But Mon, 23 Nov 2009 18:30:39 GMT Theresa http://tech.groups.yahoo.com/group/psychtoolbox/message/10319 http://tech.groups.yahoo.com/group/psychtoolbox/message/10319 I am using the DAQ Toolbox to retrieve data coming into an analog-to-digital converter. I can get a time stamp for when the converter is triggered to start Mon, 23 Nov 2009 18:28:27 GMT Schneider, Keith A. http://tech.groups.yahoo.com/group/psychtoolbox/message/10318 http://tech.groups.yahoo.com/group/psychtoolbox/message/10318 Hi Mike, Check the archives of this list for details about the FORP box. The problem is that in its normal mode, the key press impulses the FORP box sends out Mon, 23 Nov 2009 10:41:23 GMT Micheal Astley http://tech.groups.yahoo.com/group/psychtoolbox/message/10317 http://tech.groups.yahoo.com/group/psychtoolbox/message/10317 Hi All, I've seen some messages about this but following each of the suggested options hasn't gotten me anywhere so far.

The demos worked beautifully, I could see the difference between the 8 bit and 14 bit resolution Sun, 22 Nov 2009 01:14:03 GMT Mario http://tech.groups.yahoo.com/group/psychtoolbox/message/10315 http://tech.groups.yahoo.com/group/psychtoolbox/message/10315 Now "edit KbWait.m" and look at lines 115 - 122 to see what it actually does different and be amazed!

I run the latest beta and I use daq=DaqFind; and foo= DaqDin(daq, 2); but I've checked, even if I don't specify the parameters, Fri, 20 Nov 2009 04:16:36 GMT Mario http://tech.groups.yahoo.com/group/psychtoolbox/message/10312 http://tech.groups.yahoo.com/group/psychtoolbox/message/10312 Hi Susan, you are doing everything correctly. It automatically sets a 32 bit floating point resolution for the framebuffer, which corresponds to 23 bits Fri, 20 Nov 2009 02:01:10 GMT Susan Wardle http://tech.groups.yahoo.com/group/psychtoolbox/message/10311 http://tech.groups.yahoo.com/group/psychtoolbox/message/10311 Hi all, I am trying to use bit stealing on a Mitsubishi 2070SB monitor. I added the PsychImaging commands below and use luminance values between 0-1 as Thu, 19 Nov 2009 06:17:46 GMT hal.croves http://tech.groups.yahoo.com/group/psychtoolbox/message/10310 http://tech.groups.yahoo.com/group/psychtoolbox/message/10310 thanks! that solved it. hal.
