Python GPIO Error

[ikeg...@gmail.com]

Greetings. I ssh into my BB_B and I have followed this guide and everything works fine. However when I try typing this code to test my installation it doesn't work: 

1. python -c "import Adafruit_BBIO.GPIO as GPIO; print GPIO"
   
   

I get an error:

root@beaglebone:~/adafruit-beaglebone-io-python# python blink.py Traceback (most recent call last): File "blink.py", line 1, in <module> import Adafruit_BBIO.GPIO as GPIO ImportError: No module named GPIO

root@beaglebone:~/adafruit-beaglebone-io-python# python -c "import Adafruit_BBIO.GPIO as GPIO; print GPIO"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named GPIO
root@beaglebone:~/adafruit-beaglebone-io-python#

I tried to move along in the guide and typed this code into a new python file called blink.py:

import Adafruit_BBIO.GPIO as GPIO
import time
 
GPIO.setup("P8_10", GPIO.OUT)
 
while True:
 GPIO.output("P8_10", GPIO.HIGH)
 time.sleep(0.5)
 GPIO.output("P8_10", GPIO.LOW)
 time.sleep(0.5)

When I try to run blink.py I get a similar error to the one above:

root@beaglebone:~/adafruit-beaglebone-io-python# python blink.py Traceback (most recent call last): File "blink.py", line 1, in <module> import Adafruit_BBIO.GPIO as GPIO ImportError: No module named GPIO

So I know something is up with my GPIO ports but I just do not know what. Please help me.

Thanks for reading

See if Adafruit_BBIO installs correctly by running following commands separately:

opkg update

opkg install python-pip python-setuptools python-smbus

pip install Adafruit_BBIO

Changing the current directory should help.

Python is loading Adafruit_BBIO from the current (source) directory, which only contains the __init__.py file.   By changing the current directory, it will load it from the correct (installed) area, which contains the other pieces (such as GPIO.so)

I am using Beaglebone Black to run ultrasonic sensor. I am using the following code.

#!/usr/bin/env python
 
import BBIO.GPIO as GPIO                    # Import GPIO library
import time                                # Import time library
GPIO.setmode(GPIO.BCM)                     # Set GPIO pin numbering 
 
TRIG = 23                                  # Associate pin 23 to TRIG
ECHO = 24                                  # Associate pin 24 to ECHO
 
print "Distance measurement in progress"
 
GPIO.setup(TRIG, GPIO.OUT)                  # Set pin as GPIO out
GPIO.setup(ECHO, GPIO.IN)                   # Set pin as GPIO in
 
while True:
 
    GPIO.output(TRIG, False)                 # Set TRIG as LOW
    print "Waitng For Sensor To Settle"
    time.sleep(2)                            # Delay of 2 seconds
 
    GPIO.output(TRIG, True)                  # Set TRIG as HIGH
    time.sleep(0.00001)                      # Delay of 0.00001 seconds
    GPIO.output(TRIG, False)                 # Set TRIG as LOW
 
while GPIO.input(ECHO) == 0:               # Check whether the ECHO is LOW
    pulse_start = time.time()              # Saves the last known time of LOW pulse
 
while GPIO.input(ECHO) == 1:               # Check whether the ECHO is HIGH
 
    pulse_end = time.time()                # Saves the last known time of HIGH pulse 
 
    pulse_duration = pulse_end - pulse_start # Get pulse duration to a variable
 
    distance = pulse_duration * 17150        # Multiply pulse duration by 17150 to get distance
    distance = round(distance, 2)            # Round to two decimal points
 
    if distance > 2 and distance < 400:      # Check whether the distance is within range
        print "Distance:",distance - 0.5,"cm"  # Print distance with 0.5 cm calibration
    else:
        print "Out Of Range"                   # display out of range

While I try to implement it using the Beaglebone Black I am getting the following error.

"Traceback (most recent call last):

  File "ult.py", line 5, in <module>
    import BBIO.GPIO as GPIO                    # Import GPIO library
ImportError: No module named BBIO.GPIO"

I need help.

You do not say whether you have done this and are getting the error, but
have you installed the BBIO python library?

Hi I have the same problem but I don't know how to change the directory you mentioned, would you tell me how should I do it?
