Hello

I've successfuly installed tinymovr[GUI] (by use command pip3 install "Tinymover[GUI]") but when I try to start Tinymovr, I can see next messages:

C:\Users\beesj>tinymovr Traceback (most recent call last): File "C:\Users\beesj\AppData\Local\Programs\Python\Python311\Lib\site-packages\tinymovr\config\config.py", line 55, in get_bus_config return configs[0]


IndexError: list index out of range

The above exception was the direct cause of the following exception:

Traceback (most recent call last):
  File "<frozen runpy>", line 198, in _run_module_as_main
  File "<frozen runpy>", line 88, in _run_code

    raise can.CanInitializationError("No active interface found") from exc
can.exceptions.CanInitializationError: No active interface found

Can You help me in this problem? 

System is Win10, Python v3.11.4. Tinymovr rev5.2 is conneceted two ways to PC: via Serial port, and via USB-CAN-A (Waveshare). Each interface is operating, but it is to little to change configuration of Tinymovr. My target is in control device via Serial port, and use internal motor Hall sensors.

Hi @beesjot !

This error means that Tinymovr Studio is unable to detect a CAN bus interface. Upon startup, Studio tries to auto-detect a limited number of interface types, namely slcan and canine. For any other type, it needs to be specified as a command line argument (the bustype parameter), using the python-can compatible interface name.

For instance:

tinymovr --bus=socketcan

So you will need to find the python-can compatible interface name for your adapter first. Once you do that, you can pass it as an argument. If it is still not detected, it means that the python-can driver does not support channel auto-detection, and you will need to supply that as well, for instance:

tinymovr --bus=slcan --chan=/dev/ttyACM0

your chan parameter depends both on the OS as well as the device itself. For instance, in Windows, it is common to have a COM port as a channel:

tinymovr --bus=slcan --chan=COMXX

I hope this helps. I am converting this to a discussion as it is not an issue of studio. Please feel free to continue the discussion here.
