INDIGO is the next generation of INDI, based on layered architecture and software bus.

This is the list of requirements taken into the consideration:

  1. No GPL dependency to allow commercial use under application stores licenses.
  2. ANSI C for portability and to allow simple wrapping into .Net, Java, GOlang, Objective-C or Swift in future
  3. Layered architecture to allow direct linking of the drivers into applications and or to replace wire protocol.
  4. Atomic approach to device drivers. E.g. if camera has imaging and guiding chip, driver should expose two independent simple devices instead of one complex. It is much easier and transparent for client.
  5. Drivers should support hot-plug at least for USB devices. If device is connected/disconnected while driver is running, its properties should appear/disappear on the bus.

This is already done


  1. INDIGO Bus framework
  2. XML adapter for client and server side
  3. indigo_server_standalone - server with built-in drivers
  4. indigo_server - server with loadable (indigo .so/.dylib and indi executables) drivers
  5. INDIGO Server for macOS wrapper
  6. Integrated HTTP server for BLOB download & server control (= web based INDI control panel)
  7. indigo_prop_tool - command line tool to list and set properties


  1. CCD (with wheel, guider and focuser) simulator
  2. Mount simulator
  3. Atik CCD (Titan, 3xx/4xx/One with built in wheel, VS/Infinity, 11000/4000) driver
  4. Atik EFW2 filterwheel driver
  5. SX CCD driver
  6. SX wheel driver
  7. Shoestring FCUSB focuser driver
  8. SSAG/QHY5 CCD driver
  9. ASI wheel driver
  10. IIDC CCD driver
  11. ASI CCD driver
  12. NexStar mount driver (supports Celestron NexStar and Sky-Watcher mounts)
  13. LX200 mount driver (supports Meade mounts and EQMac)
  14. FLI filter wheel driver
  15. FLI CCD driver
  16. FLI focuser driver (testers needed)
  17. USB_Focus v3 driver
  18. SBIG CCD driver (with guider, guider CCD and external guider head)
  19. SBIG Filter wheel driver (part of CCD driver)
  20. ASCOM driver for INDIGO Camera
  21. ASCOM driver for INDIGO Filter Wheel
  22. QHY CCD driver (NOTE: Maybe unstable due to inherited instability in the QHY SDK)
  23. ZWO USB-ST4 port
  24. Meade DSI Camera driver
  25. Takahashi Temma mount driver
  26. ICA (ImageCapture API) driver for DSLRs (Mac only)
  27. GPS Simulator
  28. NMEA 0183 GPS driver
  29. Andor CCD driver (32/64-bit Intel Linux only)
  30. WeMacro Rail focuser driver (platform independent USB & Mac only bluetooth)
  31. EQMac guider driver (Mac only)
  32. Apogee CCD driver
  33. Moravian Intruments CCD and filter wheel driver
  34. HID Joystick AUX driver
  35. CGUSBST4 guider driver
  36. Brightstar Quantum filter wheel driver (untested)

This is under development

  1. ASCOM driver for INDIGO mount
  2. ASCOM driver for INDIGO focuser
  3. Apogee filter wheel driver
  4. GPhoto2 CCD driver
  5. SynScan (EQMod) mount driver

How to build INDIGO


Ubuntu / Debian / Raspbian

sudo apt-get install build-essential autoconf autotools-dev libtool cmake libudev-dev libavahi-compat-libdnssd-dev libusb-1.0-0-dev fxload libcurl4-gnutls-dev libgphoto2-dev git curl

It is advised to remove libraw1394-dev

sudo apt-get remove libraw1394-dev


dnf install automake autoconf cmake libtool gcc gcc-c++ libusb-devel avahi-compat-libdns_sd-devel libudev-devel libgphoto2-devel git curl

It is advised to remove libraw1394-devel

dnf remove libraw1394-devel


Install XCode and download and build autoconf, automake and libtool (use tools/ script).

Get code and build it

git clone

cd indigo

make all



bin/indigo_server indigo_ccd_asi [other drivers]

and connect from any INDIGO/INDI client to port 7624...
