  1. Hi all, I am brand new to FPGAs and am finding the documentation more confusing than enlightening regarded this issue. I am having considerable difficulty getting my PYNQ-Z1 board to output a voltage through the Arduino IO ports. Currently I have a complete circuit from Arduino IO 0 to a breadboard with an LED and resistor in series, and it connects back to the Arduino ground port. My code is as follows: In [1]: from pynq.overlays.base import BaseOverlay base = BaseOverlay("base.bit") from pynq.lib.arduino import Arduino_IO In [2]: x=Arduino_IO(base.ARDUINO,0,"out") x.write(1) However, I am getting an attribute error, which reads as follows: AttributeError ---->2 x=Arduino_IO(base.ARDUINO,0,"out") /opt/python3.6/lib/python3.6/site-packages/pynq/lib/arduino/arduino_io.py in __init__(self,mb_info,index,direction) ---->97 self.microblaze.start() Attribute Error: 'Arduino' object has no attribute 'start' What is "start" and how can I fix my code to properly output voltage? Thanks for your time.
