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.
