Steve Koch 12:57, 30 June 2009 (EDT): Occurred to me this morning that I should be able to debug everything in new stop condition VI by directly comparing with the DLL (luckily, the board_read() function doesn't crash the system).

Steve Koch 14:22, 30 June 2009 (EDT): I'm looking at Richard's "compare stop condition values" (which is at the heart of the stop condition code), and there are two things:

• It does not actually check whether condition "contains ALL the bits set in returnval"...just at least one. This is not important, since we only do one at a time, I think.
• condition is int32, not unsigned int32; same with return val. I think it should be unsigned

I am not going to update either of these things in LabVIEW because I don't want to introduce unexpected behavior, even if it does look like a bug.

I think new stop condition VI is working (aside from footswitch)

Steve Koch 16:04, 30 June 2009 (EDT): It turned into a massive VI with weird case structures (in order to keep the "return" behavior of the C code), but I think it is working:

• numdatapoints seems to work
• number of datapoints within setpoint margin seems to work
• AOD limits work (soft and hard)
• data array full works
• ANDing conditions (80000000) seems to work
