Pi-Pan README

NOTICE! You can Raspbian images with the Pi-Pan software pre-installed at the bottom of this page.

Required Operating System for Pi-Pan

Pi-Pan works with standard Raspbian distribution.
You can download it here:

http://www.raspberrypi.org/downloads

Pi-Pan Software and installation

Download appropriate GZ file from following url, and move it on your Raspberry Pi:

http://www.mindsensors.com/largefiles/pi-pan-2017-Stretch.tar.gz (For RPi 3 Model B)

http://www.mindsensors.com/largefiles/pi-pan-2016-Jessie.tar.gz (For RPi 3 Model B)

http://www.mindsensors.com/largefiles/pi-pan-2015-Jessie.tar.gz (For RPI 2 or RPi B+ with 2015 or newer Raspbian Jessie images.)

http://www.mindsensors.com/largefiles/pi-pan-for-2015-wheezy.tar.gz (For RPI 2 or RPi B+ with 2015 or newer Raspbian Wheezy images.)

Alternately, to download on your Raspberry Pi directly, run following command (use the appropriate file-name from the documents above):

cd
wget -O pi-pan.tar.gz http://www.mindsensors.com/largefiles/(file-name)

unzip the file with following command (use the appropriate file name):

tar -zxvf pi-pan.tar.gz

Pi-Pan uses ServoBlaster; For simplicity of installation, a copy of ServoBlaster is included with PiPan software. To install it run following command:

cd pi-pan
sudo ./install-pi-pan.bash

If you find yourself having issues at this point in Raspbian Stretch, you may have to run this command before running the install script:

sudo apt-get -y install python-smbus

How to Connect Pi-Pan board on your Pi

The Pi-Pan controller board connects on the Pi as in adjacent picture. (On all models of Raspberry Pi, Pin 2 is the corner pin).

Note how the PiPan Board fits on Pi

Before you assemble Pi-Pan head assembly

Bring the servos to neutral position. To do that:

Attach the controller board on GPIO pins (as in picture above).
Attach Servo wires on servo pins. (Connect the wire so the yellow-orange wire is near the white line on the PCB).
- Tilt servo (top servo) is on S5
- Pan servo (bottom servo) is on S4
Power the Raspberry Pi (Minimum power 5V, 1.2amps)

Now, to bring the servos to neutral position. run following command:

cd pi-pan
python ./neutral_servo.py

Assemble Pi-Pan with instructions from url below:
http://www.mindsensors.com/content/27-assembly-instructions-for-pi-pan-kit

After you assemble the Pi-Pan assembly

Check that you have connected servo pins correctly.
To check Pan servo, run following command:

python ./check-pan.py

To check Tilt servo, run following command:

python ./check-tilt.py

Try the demo program, run following command:

python ./demo-pi-pan.py

To Use Pi-Light

First pin on Pi-Light connector has a White square background. Also there is a White square near the first pin on controller board.

While connecting cable from Pi-Light to controller board, ensure that
the pins with White square backgrounds match on both ends.

To install required packages and enable I2C support, run following:

cd pi-pan
sudo ./install-pilight.bash

Restart your Raspberry Pi to finish configuration, run command:

sudo reboot

To check that Pi-Light is working, run:

python ./check-pilight.py

Troubleshooting Pi-Light (Optional)

Install I2C tools for troubleshooting, using following command:
(i2c-tools are not needed for Pi-Light to function).

sudo apt-get install i2c-tools

To check for i2c device. run following command:
(I2C address of Pi-Light is 18.)
For Model B:

sudo i2cdetect 1

For Model A:

sudo i2cdetect 0

result should look like this (address 18 indicates Pi-Light is found there):

WARNING! This program can confuse your I2C bus, cause data loss and worse!
I will probe file /dev/i2c-1.
I will probe address range 0x03-0x77.
