API 2 Version Difference

[LeanderM]

Hi everyone,

I have a question regarding API 2 for Robotino 2. The latest image for the Robotinos CF-Card contains the old version of the API 2, but if I want to run programs remotely e.g. from a laptop, only the newer version of API 2 is available for installation, which differs from the older Version.

Is there a newer CF-Card image containing the new version of API 2?
If not, how can I install the older API 2 on my laptop to be able to make use of it without having to program on the Robotinos directly?

Thanks in advance,
Leander

scroll down to CF card images(Robotino 1+2 until 2013) DEPRECATED

This should be API2 compatible.

Hi verbeek, thanks for your quick response!

The problem I am currently facing is that the API2 - which is part of the image you linked - differs from the API2 which is installable on your PC (e.g. the function setVelocity() of OmniDrive takes its first two arguments in mm/s on the API2 of the CF-Cards but in m/s on the installable API2, which doesn't seem compatible).

Hi,
you say "doesn't seem compatible". Is it or is it not? Did you try it? What happens?

[LeanderM]

I installed the newer API2 version and tried to modify the example programs of the Robotino 2's a bit. Trying to compile the modified program didn't work out at all, i get loads of errors - the whole example program (forward) doesn't seem to be compatible to the newer API2 version.

I also tried to extract the older API2 Version of the CF-Card Image but i can't find the .lib files, i suspect that there are none or other file types specifically for linux systems.

So currently i am not able to compile any Robotino programs on my Laptop.

And your Laptop is running ... Windows/Linux/MacOS?

[LeanderM]

My Laptop is running Windows

[verbeek]

What compiler are you using? Visual Studio 2019?

[LeanderM]

Yes, I also linked the include path of the installed API2

[verbeek]

Did you follow the instructions on

https://wiki.openrobotino.org/index.php?title=API2

[verbeek]

Linking an include path is impossible. You can link a library or you can add an include path. I would like you to follow the instructions. Use cmake to configure the example and then build the generated project with visual studio.

So the whole environment setup with CMake worked pretty well, thank you!
After building the test examples (example_circle) with the right IP of the robotino i want to adress and executing the resulting example_circle.exe, i instantly get "Com Error: Connection has been refused"

I am in the same subnet as the Robotino, which is connected to an external AP, i am also able to ping the Robotino i want to adress.
So I am not quite sure why the connection is being refused. I also tried running the .exe file as an admin and still get the same error message.

Hi, I will do some research on this next week. I will come back to you as soon as I find out whats going on.

[LeanderM]

Thank you very much!

[LeanderM]

Hi, were you able to find any solutions?
I still can not figure out why the connection is being refused. Also i am able to check the cameras of the robotinos via RobotinoView2, so it's definitely not a network problem.
