Serial Timeout with Moonlite Focuser

Hi, Jasem,

everything else in the log is irrelevant:
I can't turn on debugging of the driver. The button is non-responsive or it jumps immediately from 'ON' to 'DISABLE' (see ** in the log)

So I tried to verify what cxxone said about Kstars 3.0.0 . Of course Kstars doesn't know much about COM ports, but I used the INDI git tree to return to the commit contemporary of Kstars 3.0.0 ( git checkout a06fbccc544296333a59b585b2685f7573501952 ) recompiled it and used the last Kstars with the old indiserver (!).
Well cxxone was right, no more Timeout error and the focuser works perfectly.

Now I'm a bit stuck. The indiserver log doesn't say much about Moonlite.
Is there a way to enable debugging of the drivers from the command line when launching the indiserver ? I don't remember.

If you have an Arduino (UNO or Nano V3) it only takes 5 minutes to setup a working Moonlite (Bare, no need of a driver or a stepper motor to test ) ...
You just plug the Arduino to an USB port, use the IDE to upload the firmware and you're good to go. Really takes 5 minutes.

I've just tried and in order to turn driver logging on logging needs to be enabled in EKOS

In the logs window set verbosity to Verbose and set the Output to File.
Then logging in the INDI control panel can be enabled and remain on. I enable logging in the driver and check every box This gives a driver log in ~/.indi/logs/<date>/<driver>.

It's all a bit strange because any change in the EKOS logs settings seems to disable logging but setting verbose and file seems to cause the driver debug settings to remain.

Well here comes the MoonLite driver log.... I filtered the relevant infos to shorten the file.
It appears every serial Timeout occurs after a :GT# command (Get temperature). Sometimes the response seems to fit, and sometimes, it generates a Timeout.
One time, there is an incomplete answer (chars lost) without Timeout and not after a :GT# command. ( see ??????????? )
The response to the :GI# command (Is the motor moving ?) should have been “01” if the motor is moving, otherwise “00”
To be honest, I must say there is no physical temp probe so far, as I didn't receive the componant yet. The question now is why the Timeout only occurs sometimes?
And why did older versions did not lose chars (See my previous message), when this one does ?

What files exactly do I need to flash to Arduino UNO? I have one over here.

Thank you. I just finished testing this:

1. GT# command sometimes times out. I tried changed polling period to 1 second, which makes this timeout appear less, but it still happens at random times. Maybe the Arduino is looking for the sensor and taking quite a bit of time there? Not sure.
2. The board returns NOT MOVING even though when it is moving. It happens randomly, maybe 5-10% of the time, but it's definitely there. See screenshot below, I was at 13,000 steps and commanded it to 20,000 and at 14956, it decided to return 00# for the :GI# command. Why? beats me.

The reason you don't see these errors is because you're not running in a loop. Most of the time, these things work OK, but because the drivers continuous reads the value, you see them. The timeout error is not critical and can probably be improved with increasing the polling period. I even stopped reading temperature completely while in motion, but I still kept getting random time out commands.

Thanks a lot Jasem. :) So I guess I need to find a better firmware for my focuser :(
if someone has a good plan for this ...

Anyway, thanks again for your time and kindness.

The Moonlite hardware works well with the Moonlite driver. Better than leeching off other people's work.

Looking at that repository it's typcal linux. Precious about it's own copyright, with messages plastered over everything, while being completely contemptous of other peoples copyright, including part of MY ASCOM driver documentation.

Chris,

I'm sorry to hear this thing infringes some of your own copyrights.How would have I known ? At least, now everybody here knows it is faulty :) Thanks, Jasem !
You're not talking about the Linux world (remember, this thing runs under an Arduino, not under Linux, Windows or Mac.) You're talking about people who do not respect the work of others.
And this kind of people, you can find them on both side, Copyrights and Copylefts ;) Also, remember your beloved Mac runs under Darwin which is ... Free Software deriving from NextStep (Copyright) and BSD (Free Software). Only the GUI is Copyright. I guess things are never binary in the real world :)

Now, you've made your point and you were right to do so. Let's end this, this is not the place for that kind of discussion..

I'm not blaming you, you weren't to know of course. OTOH you were perfectly aware that this driver was built using MoonLite's proprierty work.It's the way that the whole open software scene seems to be, the most importand thing - frequently the only documentation - is a copyright message.Beloved Mac? You mut be thinking of someone else. I have an iPad which runs SkyDemon when I'm flying but for development Windows C#, RaspPi, occasionally Arduino or more likely Teensy, and PicAxe.Some of your points needed a reply but don't see a need to continue.

The sad thing is that it's easier to do this using a protocol that suits the Arduino and is more resilient.

You have something in mind ? Any suggestion ? I'm starting to think I'd better write it myself. I'm not a lazy man and I have some experience on the subject. ( But not with the Arduino .)
Any advice welcome as long as I can write it in C.
