As Howard said, OnStep cannot use the UART interface.

You can still use the TMC2209, but you are limited to microstepping of: 64,32,16,or 8.
Not a real limitation though, since it covers the range we use it at.

ZWO Asair and ZWO Asair PRO both runs on RPI


But they don’t handle hardware directly. I’ve exactly the same setup with my RP4. Think about OnStep as the electronics integrated inside your mount. The ASIAir will connect to your mount, not substitute your mount’s electronics.

Let the best tool do the task they are meant to do. If you need to control things from a raspberry pi there's a great project called indilib https://www.indilib.org/forum/development/1406-re-driver-onstep-lx200-like-for-indi.html

Thanks, that explains it. Being from the engineering world I guess I never thought about it that way. Minor revisions were always 01 thru 99. Now that I think about it that was only for readability.

I am not in favor of purely numeric versions numbers, elegant but not in common usage. Having the minor revision as a two digit number would solve the problem for me.

Orion XT10 Conversion with WEMOS R32 ESP32 and CNC Shield + some questions

bukl
 

Hi together,
I just finished converting my Orion XT10 Dobsonian to a GOTO with OnStep. First of all thanks for this great piece of Software to everyone who is involved in this.
From mechanical point of view, I mostly copied John K.´s built: https://onstep.groups.io/g/main/message/13894
But had to redesign all 3D-Printed parts since I was able to slice his STLs.

Here are some photos of my build:


The Parts I used:
quantity part price/piece € link
2 NEMA17 Stepper with 100:1 Gearbox 32,02 https://www.ebay.de/itm/392172995039
2 TMC2130 6,82 https://www.ebay.de/itm/274430359012
1 GT2 Belt 9mm 1360mm 6,32 https://www.ebay.de/itm/283708953451
1 GT2 Belt 9mm 784mm 5,35 https://www.ebay.de/itm/283708953451
1 WEMOS R32 D1 ESP32 5,73 https://www.aliexpress.com/item/32920335664.html
1 CNC Shield V3 5,8 https://www.aliexpress.com/item/2044795124.html
       
  Sum 100,88  


Although so far I had no chance to use it outside everything seems to be working fine.
Nevertheless, after using it in conjunction with the Android App I´ve got some questions:

 

Home Position

  • ·         It seems that I have to start the controller with the telescope pointing at Alt 0° Az 180°, otherwise I will not be able to align and the limits will be all over the place
  • ·         This is very inconvenient for me since I have to loosen the belts in order to manually move the telescope
  • ·         Is there a way for OnStep to figure out the limits after the alignment? I meat after I pointed it at one star OnStep should be able to figure out at which angle its pointing

Infinite Azimuth

  • ·         The way my telescope is built it is able to rotate an infinite amount of times, but when I tell it to go from Az 350° to Az 10° it turns 340° instead of going the short path of only 20°
  • ·         Can I somehow configure OnStep to allow this?

Offset between OnStep and Stellarium

  • ·         When I tell OnStep to track eg Mars from the OnStep App and then switch to the Stellarium App the circle that shows where the telescope is point is slightly offset from Mars. When tell is to track Mars from Stellarium directly the circle is spot on
  • ·         Since its been only cloudy nights so far I was able tell which of the two apps is right
  • ·         Does anybody know this problem?

ESP32 WIFI

  • ·         The ESP32 has built in WIFI which is not used by OnStep so far
  • ·         Are the any plans to implement this or should I just get an ESP8266?

Many thanks and best regards

Ok, let me qualify that last statement.  OnStep does not support UART mode for any TMCxxxx driver.

I also have no plans to add that feature at this time.

That way there is no confusion, and 5.21 will always be more than 5.07.
So you are saying the app was checking for version 4.07 or greater? I am still trying to understand what the logic behind this is. 4.21 is not greater than 4.7 this is what Martin reports in the first post.
Agree it is a bit confusing.  The "." isn't really a decimal point only a separator.

Major 4 minor 7 is < major 4 minor 21.

For some unknown reason I am not getting the needs >= 4.7 message and spiral is working.  I have no clue why since It went from fail to working without changing anything.  I am starting to question my sanity.  One thing I did seem to notice was that the onstep version splash screen on the Android app did not consistently appear...but I can’t swear to this.  At this point my problem is nominally solved and I thank everyone for their help.

Hi to all i really hope that someone could help me.
I bought MKS Gen L v1.0 board and fysetc TMC2209 v3 stepper drivers.
Problem is i dont know how to connect them in UART i tried everything and watch all tutorials i could find but on all others TMC2209 there are 3 pins on top, but on fysetc there are just two... https://wiki.fysetc.com/Silent2209/
I dont understand schematic, so i would appreciate if someone can tell me what to do.
Thanks in advance

That is correct!
Problem is when ordering components you don't always get that information.

Great piece of software. Is there a new version?


Re: OneStep on raspberry pi

Rafael Barberá Córdoba
 

I don't understand your motivations. What OnStep does, in the end, is controlling some pieces of hardware (motors). Here perfect timing and a simpler execution path is the goal. And for this, microcontrollers are vast superior. Yes is more difficult to build fancy UI using it or adding complex software, but there is not need at this level. OnStep is a very modular system with multiple microcontrollers each one performing a dedicated task. Take for example WiFi add-on. Is not only software. You need to add a dedicated micro to handle it. Why? because is simpler and more testable. You have OnStep main controller communicating via serial interface. You add another micro with WiFi capabilities talking via serial with the main OnStep one and bang, you have WiFi capabilities "built in" your system.

You need more high level software? perfect, add it to other computer and use ASCOM / INDI to communicate with OnStep ecosystem. I've done with a Mac. Now, I'm running all the software I need inside a Raspberry Pi 4. This RP4 connects via WiFi with the add-on that talks via serie interface with OnStep. Complex? Perhaps, but I only interact with one system (KStars/Ekos). At this level of modularity I was able to test each component independently and I can put a new connection at each interface. For example, I also use SkySafari on my phone to connect directly via WiFi with the mount to control it when I'm at the eyepiece.

If you put all this possibilities on a Raspberry and also tries to run the top level software (KStars/Ekos) on it you will have a lot of food on the same plate. And you need to enable all the communications with the external world (a ton of users prefer to use Windows software connecting with ASCOM). I think that the goal you have is enormous and I don't see any advantage.

I like a lot having OnStep so close to the metal. It's completely autonomous and does one thing extraordinarily well: controlling the mount. All the other task are delegates to other micros / computers.


Re: OneStep on raspberry pi

I was thinking of writing all the code from scratch in python or even reUse the C code but yeah the Arduino Libs used will be a major undertaking, I understand these are two very different universe but still wanted thoughts of people who have done this/tried this. from what i gather from all your views it will not be much of a port rather it will be parallel project from scratch. I was under impression some clever hack of running arduino code on  Rpi and pinMapping. Thanks everyone for your input

I rather meant that in the future we should make the numbers explicit so no confusion can ever occur.
That is also why I advocate purely numeric version numbers (e.g. 042101 rather than 4.21b), which can be checked easier in the code all the way down to the major/minor/patch).

I did not mean that 4.7 > 4.21, since it works correctly in my case, and for others.

Martin's situation is something else.
