The problem I saw with Ptgui was that almost after each software update the template format changed and what worked fine with the old version did not work anymore with the current version. In the end I gave up to spend time with it.

I just implemented this on my controller and it works like a charm. I bought a simple hot shoe cable and used two contacts (ground and x) to trigger an interrupt on my controller. Within the interrupt routine I'm setting a flag and check if it has been set after each trigger command. If the flag has...

Panoguy, did you ever figure out how to do the async motor control on the AVR? I couldn't tell from the posts. I wouldn't use something like that "pseudo-threading" library, as the overhead is unneeded for a fairly simple activity. !c Hi shutterdrone, no I did not implement asynch motor control, ev...

Who is still using NiMh cells ??? even the good old NiCd cells had much higher lifetime :lol:
Of course I was thinking of Lithium Ion or Lithium Fe cells.

Hi, not sure if this on the feature list already? it would be useful to display the battery voltage level of the motorized head in Papywizard. An additional command could request the battery level from the slave, let's say after each shot and update a small graph in Papywizard. For example a command...

Finally I implemented the firmware as additional function into the original Gigapanbot. So I can still use it without the Nokia and Papywizard. In addition to that I build a new board with minimal features and only one motor driver. This combo can be used nicely for pole panoramas or any other place...

A new release is available (2.1.16). I made a lot of modification on plugins architecture, for plugins using hardware (Merlin, PixOrb, PanoBot, Servo). Please, test it as much as you can, as I *really* want to release the stable version from this one (I know, I already said that several times!). Hi...

Don't forget that all plugins (yawAxis, pitchAxis, shutter) are independant, so you will receive twice F11 and F10, as the shutter also uses axis 1... Is it OK? You may need to keep track how many times an axis has been connected/disconnected. Thank you! Yes this should work, usually all used axis ...

In fact, I don't really know what the 'F' command does. Someone said that it is to check the axis controller presence. It returns nothing, so I don't know what is the goal (just using 'L' command is enough: if the axis does not work, the command will fail and that's it). I think we could remove it....

Let's say that the 'I' function is only the manual speed, and you always use the fastest speed for the goto function. We'll see later if we need an additional param for the goto speed... Is 1=slow, 2=normal, 3=fast ok for you? I would prefer the other way around, 0=fast 2=medium 4=slow this would c...

Using only 1 digit is fine for me. So, you are saying I don't need to implement the manual speed function (which is set using the home/begin PC keyboard buttons, or +- Nokia buttons)? Do you think it is interesting to add the speed limit param in the plugin, for the goto function? Or just always us...

Hi Frédéric
what is the difference between this two commands?
F<axis> Check axis
f<axis> Get status

If there is not real additional benefit to use both commands,
I would drop the F<axis> command from the Gigapanbot plugin.

One question is how do these current units report when you have gone past 360 degrees of rotation, and is it currently possible to ask for say '420 degrees'? Going past 360 is not important for stargazing, but it is for greater than 360 degree panoramas [i](overlap, looping past start point, timela...

I can show some examples; A while ago I made a similar panorama. In my case it covers only 290° and it is shot from 2 different locations. After I saw the result I was afraid that I did not move to the 3 position and finish the panorama. But the main reason for not shooting a 360° panorama was the v...

For the encoder, you only need 4 pins (2 per encoder, as they deliver quadratic signals). The problems is: is it possible to follow the rate of the encoder signals during a move? If you loose some pulses... Yes it is possible, the Atmega 168 can handle this easily. The encoder counter needs to be h...

Hi Frédéric your last advise was very helpful: The additional LF may cause some problems. Is it possible for you to only send CR? I have changed the code to send a CR only at EOL instead of CR / LF (which is the default as long it is not suppressed). Papywizard connects fine now and the communicatio...
