I'm trying to get some servos working and these instructions are not working.
Error when running Servo_Example.py
IOError: [Errrno 2] No such file or directory.
When following these directions:
https://learn.adafruit.com/adafruit-16- ... pi-for-i2c
There is no file: raspi-blacklist.conf
And the feedback page does not work.
Also this command: sudo i2cdetect -y 1 or sudo i2cdetect -y 0
does not work.
Error: Could not open file
'/dev/i2c-0' or '/dev/i2c/0': no such file or directory
I checked and these is no dev/i2c folders.
It looks like no one has tested these instructions on the Raspberry OS.
Keep in mind I'm a Windows guru not a linux guy.

sudo raspi-config, under Advanced Options select i2c and enable it

Re: Adafruit 16 Channel Servo Driver and PI 2
Take a look at this post over in the RasPi forums: http://www.raspberrypi.org/forums/viewt ... 58#p675658
The gist of it is that the latest version of Raspbian uses a system called Device Tree Overlays to configure the GPIO pins. It's the direction Linux is going in the future, but getting there involves some turbulence. A lot of things that used to work don't any more, but the post explains how to set things up again.

Re: Adafruit 16 Channel Servo Driver and PI 2
Really, so now I need to be a Linux OS expert to get this stupid board working?
How about a Raspbian distro that actually works? Hell I even bought that stupid NOOBS SD card to avoid all this and that didn't work!
And people wonder why everyone uses windows.
This way too much bs for some hobbyist to do, and you should explain that on your sales page.

Clearly you don't remember Windows's rich history of DLL conflicts and Registry hacking.
Every operating system provides users with a basic working environment suitable to a set of standard use cases. People who want to work beyond that predefined set are expected to learn more about the operating system and hardware.
If that doesn't appeal to you, send a note to [email protected] with a link to this thread and the people there will arrange a refund...

Re: Adafruit 16 Channel Servo Driver and PI 2
Um, Yes I do, but that has nothing to do with loading a hardware device. And windows solved this problem at around 1995
The difference here is, it's a Raspberry OS, and a Raspberry add-on, and you guy obvious do have a base configuration ready to download and use.
I tried just disabling DT with 'Device_Tree=' that does not work.
Does anyone at Adafruit have it working? If so here's a thought, make a zip file for people to download...
