  6. /// \mainpage RadioHead Packet Radio library for embedded microprocessors

  7. ///

  8. /// This is the RadioHead Packet Radio library for embedded microprocessors.

  9. /// It provides a complete object-oriented library for sending and receiving packetized messages

  10. /// via a variety of common data radios and other transports on a range of embedded microprocessors.

  11. ///

  12. /// The version of the package that this documentation refers to can be downloaded 

  13. /// from http://www.airspayce.com/mikem/arduino/RadioHead/RadioHead-1.61.zip

  14. /// You can find the latest version at http://www.airspayce.com/mikem/arduino/RadioHead

  15. ///

  16. /// You can also find online help and discussion at 

  17. /// http://groups.google.com/group/radiohead-arduino

  19. /// Do not contact the author directly, unless it is to discuss commercial licensing.

  20. /// Before asking a question or reporting a bug, please read 

  21. /// - http://en.wikipedia.org/wiki/Wikipedia:Reference_desk/How_to_ask_a_software_question

  24. ///

  25. /// \par Overview

  26. ///

  27. /// RadioHead consists of 2 main sets of classes: Drivers and Managers.

  28. ///

  29. /// - Drivers provide low level access to a range of different packet radios and other packetized message transports.

  30. /// - Managers provide high level message sending and receiving facilities for a range of different requirements.

  31. ///

  32. /// Every RadioHead program will have an instance of a Driver to provide access to the data radio or transport, 

  33. /// and a Manager that uses that driver to send and receive messages for the application. The programmer is required

  34. /// to instantiate a Driver and a Manager, and to initialise the Manager. Thereafter the facilities of the Manager

  35. /// can be used to send and receive messages.

  36. ///

  37. /// It is also possible to use a Driver on its own, without a Manager, although this only allows unaddressed, 

  38. /// unreliable transport via the Driver's facilities.

  39. ///

  40. /// In some specialised use cases, it is possible to instantiate more than one Driver and more than one Manager.

  41. ///

  42. /// A range of different common embedded microprocessor platforms are supported, allowing your project to run

  43. /// on your choice of processor.

  44. ///

  45. /// Example programs are included to show the main modes of use.

  46. ///

  203. ///

  204. /// \par History

  205. ///

  206. /// RadioHead was created in April 2014, substantially based on code from some of our other earlier Radio libraries:

  207. ///

  208. /// - RHMesh, RHRouter, RHReliableDatagram and RHDatagram are derived from the RF22 library version 1.39.

  209. /// - RH_RF22 is derived from the RF22 library version 1.39.

  210. /// - RH_RF69 is derived from the RF69 library version 1.2.

  211. /// - RH_ASK is based on the VirtualWire library version 1.26, after significant conversion to C++.

  212. /// - RH_Serial was new.

  213. /// - RH_NRF24 is based on the NRF24 library version 1.12, with some significant changes.

  214. ///

  215. /// During this combination and redevelopment, we have tried to retain all the processor dependencies and support from

  216. /// the libraries that were contributed by other people. However not all platforms can be tested by us, so if you

  217. /// find that support from some platform has not been successfully migrated, please feel free to fix it and send us a 

  218. /// patch.

  219. ///

  220. /// Users of RHMesh, RHRouter, RHReliableDatagram and RHDatagram in the previous RF22 library will find that their

  221. /// existing code will run mostly without modification. See the RH_RF22 documentation for more details.

  222. ///

  223. /// \par Installation

  224. ///

  225. /// Install in the usual way: unzip the distribution zip file to the libraries

  226. /// sub-folder of your sketchbook. 

  227. /// The example sketches will be visible in in your Arduino, mpide, maple-ide or whatever.

  228. /// http://arduino.cc/en/Guide/Libraries

  229. ///

  230. /// \par Building for Particle Photon

  231. ///

  232. /// The Photon is not supported by the Arduino IDE, so it takes a little effort to set up a build environment.

  233. /// Heres what we did to enable building of RadioHead example sketches on Linux, 

  234. /// but there are other ways to skin this cat.

  235. /// Basic reference for getting stated is: http://particle-firmware.readthedocs.org/en/develop/build/

  236. /// - Download the ARM gcc cross compiler binaries and unpack it in a suitable place:

  237. /// \code

  238. /// cd /tmp

  239. /// wget https://launchpad.net/gcc-arm-embedded/5.0/5-2015-q4-major/+download/gcc-arm-none-eabi-5_2-2015q4-20151219-linux.tar.bz2

  240. /// tar xvf gcc-arm-none-eabi-5_2-2015q4-20151219-linux.tar.bz2

  241. /// \endcode

  242. /// - If dfu-util and friends not installed on your platform, download dfu-util and friends to somewhere in your path

  243. /// \code

  244. /// cd ~/bin

  248. /// \endcode

  249. /// - Download the Particle firmware (contains headers and libraries require to compile Photon sketches) 

  250. ///   to a suitable place:

  251. /// \code

  252. /// cd /tmp

  253. /// wget https://github.com/spark/firmware/archive/develop.zip

  254. /// unzip develop.zip

  255. /// \endcode

  256. /// - Make a working area containing the RadioHead library source code and your RadioHead sketch. You must

  257. ///   rename the sketch from .pde or .ino to application.cpp

  258. /// \code

  259. /// cd /tmp

  260. /// mkdir RadioHead

  265. /// \endcode

  266. /// - Edit application.cpp and comment out any #include <SPI.h> so it looks like:

  267. /// \code

  268. ///   // #include <SPI.h>

  269. /// \endcode

  270. /// - Connect your Photon by USB. Put it in DFU mode as descibed in Photon documentation. Light should be flashing yellow

  271. /// - Compile the RadioHead sketch and install it as the user program (this does not update the rest of the

  272. ///   Photon firmware, just the user part:

  273. /// \code

  274. /// cd /tmp/firmware-develop/main

  275. /// PATH=$PATH:/tmp/gcc-arm-none-eabi-5_2-2015q4/bin make APPDIR=/tmp/RadioHead all PLATFORM=photon program-dfu

  276. /// \endcode

  277. /// - You should see RadioHead compile without errors and download the finished sketch into the Photon.
