Could be. Both the driver and sketch should default to 1000 but the driver also sends an Innnn# command to the nano to set its initial position to the value you entered in the chooser aswell. SF may be using a different startup path in the driver. Do you get any trace files when using the SF auto start method. If so you will see if there is an Innnn# command in there.

Hmmm. Maybe FM is using that value over the value the focuser initially has. I'll have to look into how these devices/drivers save and use the last position between connects or power down/up. More research

Does it work ok using the manual method. If so you can set the initial position in the chooser dialog. Maybe it is something to do with the way FM is filling in the chooser. When I get some more time Ill do some testing with FM. Are you sure you have the correct driver installed and registered.

Excellent. One question - why do you want to be Swiss?

I love it.

I have now updated the circuit schematic on the SF site. Here's a preview. This was produced using gEDA on Linux.

Cheers Mick. I have now uploaded the 2 required libraries to the Files section of the SF site so they are with the other project files https://sourceforge.net/projects/arduinoascomfocuser/files/Mark2/Software/V2.2.0/ Instructions on how to install them via the Arduno IDE are here: http://arduino.cc/en/Guide/Libraries Just download the zip files, don't unzip them, follow the instructions on the above page under the 'Automatic installation' section. Then recompile & upload the sketch and you should be good to go.

Thanks Mick. I was thinking the library code will be compiled into the sketch but it is only source code. The end user will need to install the libraries. Shame we can't distribute a pre-compiled binary of the sketch. Are the links in my previous post correct?

I think the problem is that the libraries required for the 1-wire and and Temperature sensor have not been installed on your PC. This will cause the error you are getting. If you can upload without compiling it will work but I don't think the arduino software will let you do that. I'll post some instructions on downloading and installing the libraries or look here http://arduino.cc/en/Guide/Libraries The libraries you need are: OneWire https://www.pjrc.com/teensy/td_libs_OneWire.html DallasTemperature http://milesburton.com/Main_Page?title=Dallas_Temperature_Control_Library I hope those are the correct links. Ill do some better instructions later and also include the required libraries on the SF site with the rest of the project files. Thanks for spotting that - I hadn't considered the fact that you have to compile the sketch in order to just upload it to the nano.

I have just reproduced the above problem by running the latest driver & FocusAAF2 applications (V2.2) but with the older (V2.1.3) sketch on the nano. Putting the V2.3 sketch on the nano cures the problem. For some reason my numbering schemes between the Driver & Arduino sketch have got out of step. From now on they will be numbered the same to avoid confusion.

It will work with or without the temp sensor attached. Make sure you have uninstalled the old version of AAF2 before downloading and installing V2.2 from sourceforge. Also make sure you upload latest arduino sketch to the nano.

You can only edit each post for a limited time after posting it I'm afraid. Not sure what the answer to the com port issue is.

Phew, you had me worried then.

Glad you got it installed so quickly. I'm still waiting for the temperature probe I ordered from China. I am planning to put a standard 1-wire RJ11 connector in my focuser case to connect it all up.

I have uploaded release 2.2.0 to the SF Site http://sourceforge.net/projects/arduinoascomfocuser/ This implements the Temperature sensor functionality. A big thanks to russellhq who worked out all the details for me. I have worked most of the code supplied into my project with minor mods. I will update the circuit diagram on the SF site with the DS18B20 connection details asap but it basically follows the diagram that russellhq posted; Don't worry if you don't want to fit the temperature sensor - the focuser will continue to work but will return a temperature of 0C to any applications that try to read it. I have added a simple temperature readout to the FocusAAF2 test utility - it should report the temperature 10s after connecting to the focuser and then every 10s until you disconnect. I don't have any client programs that display the temperature except BYEOS but that seems to have gone a bit flaky on me at the moment. As ever I would appreciate any feedback.

Don't ya just love those semi-colons

As Mick has suggested I snipped all the pins off the nano to allow it to fit in the small box I used. It is also soldered to a piece of veroboard and the excess pins snipped off. This was so I could use the pcb mounting slots in the box. If you do this make sure you break the veroboard tracks to avoid connecting pins on one side of the nano to the pins opposite.

250 posts till you can edit your own posts.

Thanks Mick - you beat me to the answer.

Hi Robert and thanks for downloading my project. The driver assembly is installed it just isn't registered so the rest of the system can 'see' it. Unfortunately I haven't worked out how to get the installer to automatically register the driver correctly yet. There is a work-round where you can register it manually using the regasm utility, which is part of the .net framework already installed on your PC.The details are in this topic at post #57 (on page 3). I need to find the time to sort this out once and for all but other projects and commitments (like work!) keep getting in the way.

Thanks for trying Gina

Oops, sorry I misread who the last message was from

Thanks Gina, looks like you will have 2 credits in the sketch

The latest on my Sourceforge site is V2.1.3 http://sourceforge.net/projects/arduinoascomfocuser/files/Mark2/Software/V2.1.3/

Thats strange - I ordered one of those last night. I thought it would be handy to have a probe to position wherever it was needed to get the correct temperature.
