Adafruit 16-Channel Servo Driver smbus not defined

Post by nonlinearmind »

I'm trying to get a Servo motor running using the tutorial.

I've changed the smbus settings for the RPi revision and keep getting the following error from line (30) that I changed in Adafruit_PWM_Servo_Driver.py

Code: Select all

self.i2c = Adafruit_I2C(address, bus=smbus.SMBus(1))
NameError: global name 'smbus' is not defined
What am I doing wrong??

Did you install the smbus library?

Before you start, you'll need to have the python smbus library installed, run apt-get install python-smbus

I had it installed. Here's what I get back when I run Servo_Example.py:

pi@raspberrypi ~/Adafruit-Raspberry-Pi-Python-Code/Adafruit_PWM_Servo_Driver $ sudo python Servo_Example.py
Traceback (most recent call last):
File "Servo_Example.py", line 12, in <module>
pwm = PWM(0x40, debug=True)
File "/home/pi/Adafruit-Raspberry-Pi-Python-Code/Adafruit_PWM_Servo_Driver/Adafruit_PWM_Servo_Driver.py", line 30, in __init__
self.i2c = Adafruit_I2C(address, bus=smbus.SMBus(1))
NameError: global name 'smbus' is not defined
