The programmer is required /// to instantiate a Driver and a Manager, and to initialise the Manager. Thereafter the facilities of the Manager /// can be used to send and receive messages. /// /// It is also possible to use a Driver on its own, without a Manager, although this only allows unaddressed, /// unreliable transport via the Driver's facilities. /// /// In some specialised use cases, it is possible to instantiate more than one Driver and more than one Manager. /// /// A range of different common embedded microprocessor platforms are supported, allowing your project to run /// on your choice of processor. /// /// Example programs are included to show the main modes of use. /// /// \par Drivers /// /// The following Drivers are provided: /// /// - RH_RF22 /// Works with Hope-RF /// RF22B and RF23B based transceivers, and compatible chips and modules, /// including the RFM22B transceiver module such as /// this bare module: http://www.sparkfun.com/products/10153 /// and this shield: http://www.sparkfun.com/products/11018 /// and this board: http://www.anarduino.com/miniwireless /// and RF23BP modules such as: http://www.anarduino.com/details.jsp?pid=130 /// Supports GFSK, FSK and OOK.
