  1. So after installing that huge obsolete Xilink ISE WebPack Design tools which is what was needed to edit circuits for the Spartan 6 FPGA on the Papilio Pro, I went on to open the DesignLab IDE, click on new circuit, and then edit circuit to create and edit a new schematic when I get this error. The clicking of the edit button should have opened the ISE project navigator like in one these videos (https://www.youtube.com/watch?v=XHhU5JiKdUY) that show how to go about making FPGA circuits using the IDE. I am instead getting this error (see attachment), can anybody guess why? I have tried running the program as admin and I will try reinstalling the IDE, but I think the problem lies elsewhere.
  2. Hi! I am trying to use a Papilio Pro to run a stepper motor since the Teensy, Arduino microcontrollers proved insufficient for my purposes. I am interfacing the Papilio pro with the L6470 IC which is going to be the motor driver. My main problem is this - I am keen on using a Python module to control the stepper motor but I have no clue as to how to go about writing the code for the Papilio Pro which will be the board that will receive the bits sent via the Python code and will reroute it through the IC which will translate that in to stepper motion. The bits here are basically my position, speed values, etc. I have plans for sending entire waveforms, say, to make the motor oscillate between two positions and so on. I was wondering how I should go about this project?
