indi_getprop mount busy or not was created by pauledd

Hi
Inspired by EQASCOM's Polaris Alignment Tool I currently write my own one (c++ qt very-noob beginner project...) that talks to an indiserver.
At step 2 I want the mount to go to the home position and unpark.
File Attachment:


My current code simply sends the two commands for park and unpark.

void AlignmentDialog::slewHome()	// Park to Home and unpark
{
	QString program = "/usr/bin/indi_setprop";
	QStringList arguments;
	arguments << "-h" << ui->lineEdit->text() << "EQMod Mount.TELESCOPE_PARK.PARK=On";
	QProcess *myProcess = new QProcess(this);
	myProcess->start(program, arguments);
	myProcess->waitForFinished();
	arguments.clear();
	arguments << "-h" << ui->lineEdit->text() << "EQMod Mount.TELESCOPE_PARK.UNPARK=On";
	myProcess->start(program, arguments);
	myProcess->waitForFinished();
}

The problem with that is the mount tries to park and moves very short and then stops. I guess I have to add some check
for the mount being busy while moving to the park position and then issue the unpark command.
Does someone know which value from indi_getprop I can use for that?
The ones I found seem a bit strange to me because there are some busy even when the mount is not moving:
indi_getprop -h rp | grep STATUS
EQMod Mount.RASTATUS.RAInitialized=Ok
EQMod Mount.RASTATUS.RARunning=Busy
EQMod Mount.RASTATUS.RAGoto=Busy
EQMod Mount.RASTATUS.RAForward=Ok
EQMod Mount.RASTATUS.RAHighspeed=Busy
EQMod Mount.DESTATUS.DEInitialized=Ok
EQMod Mount.DESTATUS.DERunning=Busy
EQMod Mount.DESTATUS.DEGoto=Busy
EQMod Mount.DESTATUS.DEForward=Ok
EQMod Mount.DESTATUS.DEHighspeed=Busy
--= human, without Windows™ =--

It seems "Busy" means "Idle".
I will try to use EQMod Mount.DESTATUS.DEGoto / EQMod Mount.RASTATUS.RAGoto

you can get it here but it does not work as expected yet and the align routine is not added yet and its written to talk to "EQMod Mount" only. Use it at your own risk :pinch:

Please dont try it yet :whistle:
You could start indiserver with your mount and use "indi_getprop" to test if it communicates correctly and test some of the properties with "indi_setprop". My program does the same, in theory

should work now.

By the way and regarding the topic, I removed the function to park and unpark with one button. Instead I made separate buttons for that. Until I will try to find a way to check if the mount is busy or idle later one has to check visually if the park process has finished and because you already have to be next the mount to look through the polar scope.

I wouldn't be using indi_getprop, but I can see how it can be easier than writing the program as an INDI client. What's the use case for this? On field setup for visual north hemisphere polar alignment? This assumes there is no hand set?

If you have clear view to south you dont need this. Yes, its (in my case just north) pure visual alignment using polaris.
EQASCOM implemented this tool long ago eq-mod.sourceforge.net/docs/PolarScopeAlignment.pdf
I really need this because my telescope location only allows polaris alignment, I have no view to south.
I got quite good alignment results with this method.

Ok quick read on that it seems it is useful for slewing the RA so you can quickly adjust Alt/Az knobs to center Polaris in the polar scope. Otherwise, you'd have to guesstimate the relative orientation of Polaris and then move the RA axis manually in order to center it, but it might be off. With this procedure, the RA drive rotates precisely.

But it seems your program is doing a simpler approach?
