oh, my mistake, yes, it should be uplinkDataReady = 0.

I don't remember that.  I might have changed it and thought I changed it back, as the conditions for the errors are right.  Might have been my sleep deprivation  Bangs Head

I've been trying to get the clock precisely, using what you suggested, but its a bit off from the mission timer.  I might have to manually hit enter instead of queueing it to make it work.  I was thinking of setting it to 10 seconds, and then have the queue wait as normal until the 10 seconds is up, then send a signal manually.

Thanks for the fixes!  Happy

About the clock: Another possibility might be to determine the difference between mission time and the clock after a first (absolute) update (again a hard one, perhaps reading downlink telementry like GroundStation.exe ?) and then to use V55 to increment/decrement the clock, which shouldn't be timing critical as it's relative, but I have not even tried V55...

Just tried it, and its rather simple.  Just add the hours, minutes, and seconds to it.  I'll check the telemetry client to see how to fetch the time, but I'd prefer this over the other way.

Sounds good!

I added a mini feature to PAMFD for development/testing purpose: On the GNC screen there's now a KILR button = "Kill rotation", which sets the angular velocity to zero each timestep. It's a poor dirty cheat for lamers like me, who aren't able to control spacecraft attitude properly with the minimum impulse controller while marking a star in the sextant...  What? Wink

I also did some very cosmetical display changes, besides that the new stuff is working fine, great work!  Happy

always helps for dev  Thumbs Up

isn't there a mode to keep the stack relatively still?

Also, i'm going down to the cape tomorrow for about a week or so to see the launch, so I'll be gone for a while.

Yes, there are attitude hold modes, but the deathbands are much too large for having a star really not moving in the sextant. Of course, if you have the right stuff, you don't need that and move the sexant and control the spacecraft simultaneously.  Happy

Also, i'm going down to the cape tomorrow for about a week or so to see the launch, so I'll be gone for a while.

Wow, now I'm getting really jealous...  Wink
Have a nice trip, I hope there are no scrubs and you can see the launch!

hope so too.  I'll be visiting the Saturn V center as well, so expect some pictures  Happy

Ok, got the Clock Update function to work, which is a mix of the two methods.  The MFD does not like to read data from the AGC for whatever reason (probably a timestep issue), so I went around it by setting the clock to 00:00:00, and right as its all finished being inputted into the agc, the current mission time is taken at that exact moment, and V55 is run to add the current mission time to the current clock.

It's committed to the CVS

Thanks, looks good, but I don't know how to test that this is really precise...
Anyway, for me it's fine for now, I only added a "V37E00E" at the end of the clock update to turn off the UPLINK light.

By the way: Did you have the chance to see the shuttle launch?  Happy

Well, as long as its close enough.  I'm pretty sure its precise enough.

And I did see the launch.  Only saw it going up for a bit before it hit the clouds, but still awesome to watch.  I have pictures, but works been too busy lately.
