IO Protocol information for OS port

[Ramon]

Hi,
I currently own a Robotino v2. I had successfully ported it to QNX operating system since the IO protocol documentation between the PC/104 and IO board was public.
Now I am planning to replace it with a Robotino v4. I would like to port the software as well to QNX operating system. Where could I get information on how to access IO data from the IO board?

I would like to be able to develop QNX code on the Robotino to autonomously command it.

Cheers,
Ramon

Hello Ramon,
we are working on a ros2 robotino node that directly communicates with Robotino4's IO board. I attached the code. You can take this to implement your QNX driver.

Thank you Christian.
I see that some code for Robotino3 is used in the Robotino4 implementation.
Is the following still valid for Robotino4?

Robotino3 and Robotino4 are identical in terms of the IO protocol.

Great. Thanks

Hello,

we also have a robotino 2, what should be revived for some student lab tasks. Unfortunately, a student who shoud care for that had given up and looked for some more easy project for his assigment (
Anyway, I would like to see the protolcol description for that interface, where the RPi had been attached in the proposed upgrade. Probably, we will do that as well, but I like to see the protocol first (serial on RS232 basis?).
Unfortunately, I was unable to find it, neither here nor via &oogl% ..

Probably, it could be reposted?

Thanks&Regards,
Jürgen

Its a serial protocol. I have not published the sources or documented the protocol somewhere.

Ahh ok, then I misunderstood Ramon's post and your answer ...it sounded like the protocol had been published. I wanted probably to give our robotino2 with that IO board and protocol to some students who could experiment with different boards and experiment with it. Looks like we then should do a full conversion to RPi as you described ...and shold work with ROS ...
