RE: Which Adafruit_BBIO Library AM I Running on My BBB?

[silver2row]

Hello,

I have tried to figure out which Adafruit_BBIO I am running on my BBB but to no avail. Do you know? How can I find out this info?

Try running this command:
python -c "import Adafruit_BBIO; print Adafruit_BBIO"

For example, this is the output on my beaglebone:

Code: Select all

debian@beaglebone:~$ python -c "import Adafruit_BBIO; print Adafruit_BBIO"
<module 'Adafruit_BBIO' from '/usr/local/lib/python2.7/dist-packages/Adafruit_BBIO-1.0.10-py2.7-linux-armv7l.egg/Adafruit_BBIO/__init__.pyc'>

Hello Sir,

I downgraded to 1.0.5 when that fellow Yoder was writing the I2C driver as Adafruit_I2C. I then upgraded to 1.0.10 again. I downgraded from kernel 4.14.x to 4.9.x again.

If you notice anything that is different on my system compared to your system, please let me know. I got 1.0.5 to work partially but not the 1.0.10 yet.

Seth

P.S. Thank you for the cmd to find out which Adafruit_BBIO is running on my system. Oh and sir, do I need Adafruit_Python_GPIO library to run specific software on my system? I do not have Adafruit_BBIO in that specific PATH. I tested your cmd and it stated:

Code: Select all

debian@beaglebone:~$ python -c "import Adafruit_BBIO; print Adafruit_BBIO"
Traceback (most recent call last):
  File "<string>", line 1, in <module>
ImportError: No module named Adafruit_BBIO

[silver2row]

Hello Sir,

I checked the PATH and Adafruit_BBIO is located where it should be, i.e. in usr/local/lib/python2.7/dist-packages.

Seth

P.S. There is nothing to see in my 1.0.10 Adafruit_BBIO software. I checked the file. It is empty.

[drewfustini]

Please try running python as root with sudo.

This will make sure Adafruit_BBIO is up-to-date.
sudo pip install --upgrade Adafruit_BBIO

This will print out which version is installed:
sudo python -c "import Adafruit_BBIO; print Adafruit_BBIO"

This will list the Adafruit libraries installed:
ls -ltar /usr/local/lib/python2.7/dist-packages/|grep -i adafruit

Hello Sir,

Seth here agan and again. I am receiving

Code: Select all

no module named Adafruit_BBIO

when I type in the cmd you gave me. I upgraded like you said w/ sudo and used sudo when applying the cmd.

Seth

[drewfustini]

You could also install from source using these commands:

Code: Select all

sudo apt-get update
sudo apt-get install build-essential python-dev python-pip -y
git clone git://github.com/adafruit/adafruit-beaglebone-io-python.git
cd adafruit-beaglebone-io-python
sudo python setup.py install

Hello...

I got it now. The Adafruit_BBIO is now installed and working...sort of. Now, as you know, I use the Motor Bridge Cape from Seeed Studio on a BBB/BBG/BBGW/BBBW. In my experience, the I2C driver has worked for me just by changing some software b/c Seeed Studio must have not known what the BBB.io people were doing at the time they produced the Motor Bridge Cape.

Anyway, no matter how trivial that is now, I have concerns w/ the software for the i2c driver in Adafruit_BBIO. Do I need Adafruit_Python_GPIO to work w/ adafruit-beaglebone-io-python?

Seth

P.S. I get errors. Please see below...

Code: Select all

Traceback (most recent call last):

Adafruit_BBIO implements its own GPIO and does not use Adafruit_Python_GPIO.

P.S. I get errors. Please see below...

Code: Select all

Traceback (most recent call last):
  File "mbcUse.py", line 1, in <module>

SyntaxError: invalid syntax

I believe the syntax should be:

Code: Select all

import Adafruit_GPIO.I2C as I2C

Take a look at the I2C test in the Adafruit_Python_GPIO module:
tests/test_I2C.py Line 82

Oops!

Hello,

How can I define Adafruit_GPIO?

Seth

[silver2row]

Hello,

Here is my output from my software being run as sudo python mbcUse.py from the MotorBridge.py library. First, the output:

Code: Select all

Traceback (most recent call last):
  File "mbcUse.py", line 1, in <module>
    import MotorBridge
  File "/home/debian/MotorBridgeCapeforBBG_BBB/BBG_MotorBridgeCape/MotorBridge.py", line 40, in <module>
    MotorBridge = Adafruit_GPIO.I2C(0x49)
NameError: name 'Adafruit_GPIO' is not defined

Second...the MotorBridge.py file as it has changed to suit the needs of the Adafruit_BBIO setup:

Code: Select all

# FileName : MotorBridge.py
# by Jiankai.li

from Adafruit_GPIO import (I2C, GPIO)
import Adafruit_GPIO.I2C as I2C
import Adafruit_BBIO.GPIO as GPIO
import time
Reset = "P9_23"
MotorBridge = Adafruit_GPIO.I2C(0x49)
GPIO.setup(Reset, GPIO.OUT)

ReadMode  = 0
WriteMode = 1
DeAddr    = 0X4B
ConfigValid =  0x3a6fb67c
DelayTime = 0.005

Seth

P.S. If this gives any insight into what I have constructed, please let me know your thoughts.

[silver2row]

Hello Sir,

I found config-pin at https://github.com/adafruit/adafruit-be ... -io-python. Do I need to situate config-pin, e.g. config-pin P9.21 i2c and config-pin P9.22 i2c?

I am asking b/c I found one of your posts on this message board and you stated your "current configuration" and I copied that configuration on my BBG in the uEnv.txt file but I still could not get the Motor Bridge Cape to recognize my software, Adafruit_BBIO, and the MotorBridge.py file (all jumbled together).

Seth

P.S. Here is some extra info:

Code: Select all

[    1.692282] pinctrl-single 44e10800.pinmux: pin PIN94 already requested by ocp:P9_20_pinmux; cannot claim for 4819c000.i2c

I got this from dmesg.

NameError: name 'Adafruit_GPIO' is not defined

You will need to import Adafruit_GPIO before using it. For example:

Code: Select all

import Adafruit_GPIO as GPIO

This test program demonstrates the usage:

Hello,

I got GitHub.com Desktop to do stuff. I cannot get anything updated on my side of things. Besides that being my issue, you are correct. I saw the link you posted. Thank you, sir. I was doing this instead of what you instructed:

Code: Select all

import Adafruit_BBIO.GPIO as GPIO

while I should have been doing this:

Code: Select all

import Adafruit_GPIO as GPIO

You saved my skin again sir. Thank you.

Seth
