Error when running a task file with position tracking sensor

[CGomes]

Hi!

I'm trying to measure x and y positions using the sensor PMW3360. I'm loading the hardware definition file attached below and running the task 'task.py' also attached. Inside my devices folder, I have the code 'sensor.py'.

When I run the task I get the following error, which I'm not sure how to solve. Any help would be greatly appreciated. Thank you very much!

Error: Unable to setup state machine.

Hi,

I think the issue is occurring because the MotionDetector_2ch class in the file sensor.py is designed to work with a modified version of the pyControl framework developed by Mostafa (see discuss thread here), so when you try and use it with standard pyControl you get this error.   I suggest you contact him or the person who provided the sensor.py code, to ask for help in getting it working.  I think the version of pyControl you need is in this branch of Mostafa's github but i'm not 100% sure as i did not develop this code. 

best,

Thomas
