 +====== Introduction ======
 DIY Antenna Tracker and OSD using STM32F4 . DIY Antenna Tracker and OSD using STM32F4 .
  
-Ground side tracker. +This board is aimed at developersIt is currently being used to create ​an OSD for aircraft and to power an Antenna Tracker (in development). It is currently being used as the basis of  a  [[http://​en.playuav.com/​question/​4|Flight Controller]] by adding external components. (In development
-   Uses a Pololu style servo motor with encoder ​to give continuous Azimuth rotation +
-   Uses a standard RC Servo for elevation. +
-Airborne side  +
-   ​uses ​an OSD with telemetry via the video to send telemetry data to the tracker. +
-   or an Arduino ​basic option if you have a FrSky Telemetry RC system)+
  
-see my website http://​www.zoomworks.org/​fpv/​quantracker/​doc/​index.html for more info about the project.+=== Features ====
  
-See the Changelog file in this directory for changes after 16/07/2013+STM32F4 microcontroller
  
-Acknowledgments+Black, white or gray overlay colours.
  
-      With Grateful Acknowledgements ​to the prior work, on the OSD code of:+On-board switching regulator. The board can be powered by any voltage from 7 to 25 volts (or by a regulated 5 volt power)
  
-        Sami Korbonen(Openpilot.org) +The OSD can transmit or receive data via the video signal itself, so requiring no external transmission link for telemetry, though it can also simultaneouslyy transmit via a video audio channel or via a modem using a uart.

-        Special Thanks to Andrew Fernie for his work on the Hardware ​and Software.+Automatically detects NTSC or PAL video inputs ​and adjusts screen size accordingly.
  
-Dependencies+Default display output when there is no camera input or if the camera fails.
  
-   The GNU gcc compiler. The source code is written in C++11, and requires gcc4.7 or higher +Simple uploading of firmware via the serial port, using a standard 6 pin Arduino style FTDI to usb connector. The board can also be programmed using ST-Link.
-   to compile. +
-   ​available from +
  
-         ​https://​launchpad.net/​gcc-arm-embedded +2 dedicated electrically isolated serial ports (UART), so that the Video subsystem (Camera, Vtx and OSD) can be electrically isolated from noise in other circuitry to provide a clear picture but can still communicate fast and reliably with other parts of the system.

-         TODO May need some file dir renaming to get the directories right for compiling +
-       +
- +
-Once these are installed you will need to modify the paths in the Makefiles to suit your configuration. +
-See the file Sample-Dependencies.mk in the root directory for details of how to fill in dependencies +
- +
-The ground tracker relies on some means on the aircraft to get the telemetry back to the tracker +
- +
-The OSD can however be built as stand alone item. There are currenetly 2 customised example OSD,s in the quantracker/​examples directory. +
-airborne option to send the data to the tracker from the aircraft. +
- +
-So far there are several airborne options +
- +
-  1) Use the OSD airborne module which uses the Video link direct to send telemetry. +
-     ​This ​is currently in development but the design is all open source and in the repo. +
-     I hope to have a retail version soon. +
- +
-  2) using an Arduino Pro Mini microcontroller and an FrSky Rx ( simple cheap) +
- +
-     a) Use an Frsky Telemetry receiver and an Ardupilot to acquire the GPS data. +
-      The source code for this option can be downloaded from +
- +
-         https://​github.com/​kwikius/​mavlink_to_frsky +
- +
-     b) Use a GPS module attached direct to the Arduino and sending data down the FrSky telemetry link +
