Building INDI Tutorials

INDI Library currently ships with seven tutorials in the examples subdirectory. To build the tutorials, first install some pre-requisties on Ubuntu:

sudo apt-get install cdbs libcfitsio-dev libnova-dev libusb-1.0-0-dev libjpeg-dev libusb-dev libtiff5-dev libftdi-dev fxload libkrb5-dev libcurl4-gnutls-dev libraw-dev libgphoto2-dev libgsl0-dev dkms libboost-regex-dev libgps-dev libdc1394-22-dev

Then checkout INDI Library code from Github and build it:

mkdir ~/Projects
cd ~/Projects
git clone https://github.com/indilib/indi.git
mkdir -p build/libindi
cd build/libindi
cmake -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Debug ~/Projects/indi/libindi
sudo make install

To run tutorial one for example, simply run:

indiserver -v examples/tutorial_one/tutorial_one

This will create an INDI server running tutorial one driver on port 7624 (by default) on the local machine. You can connect to the INDI server using any INDI compatible client such as KStars. If you are using KStars, perform the following steps:

    1. Select the Device Manager menu item from the Tools menu
    2. Select the client tab and add a new host

    3. Click Connect in the device manager to connect to INDI server running Tutorial One
    4. Client Connect/Disconnect to test tutorial one simple functionality in INDI Control Panel
    5. The INDI Library tutorials cover some of the basic aspects of INDI, namely:
Tutorial Driver Description
One Simple Device The most simple INDI driver. The tutorial covers what is required to build and run a minimal INDI driver.
Two Simple Telescope Implementation of a simple telescope driver using INDI event-driven framework
Three Simple CCD Implementation of a simple CCD driver that sends a randomly generated image to the client as FITS.
Four Skeleton Demonstration on how to utilize INDI's skeleton files to build driver properties externally.
Five Rain and Dome Demonstration of INDI Snooping functionality that enables inter-driver communication.
Six Client Application Implmentation of a simple client application that can connect to the Simple CCD driver and controls its temperature.
Seven Advanced Telescope Simulator Sample implementation of a telescope driver that utilizes INDI's Alignment Subsystem Infrastructure

In this tutorial we will create the most basic INDI driver: a simple device! The simple device performs no functions, it just connects and disconnects.

All INDI devices inherit from INDI::DefaultDevice. Some specialized classes like INDI::Telescope also inherits from INDI::DefaultDevice and specific telescope drivers then inherit from INDI::Telescope.

Let's checkout the header file for Simple Device, which is included in the INDI Library package

#include "indibase/defaultdevice.h"

class SimpleDevice : public INDI::DefaultDevice
{
public:
    SimpleDevice();

protected:
    bool Connect();
    bool Disconnect();
    const char *getDefaultName();

};
