RadioHead Packet Radio library for embedded microprocessors from http://www.airspayce.com/mikem/arduino/RadioHead/
Chnages from aprendiendoarduino
This is the RadioHead Packet Radio library for embedded microprocessors. It provides a complete object-oriented library for sending and receiving packetized messages via a variety of common data radios and other transports on a range of embedded microprocessors.
The version of the package that this documentation refers to can be downloaded from http://www.airspayce.com/mikem/arduino/RadioHead/RadioHead-1.83.zip You can find the latest version of the documentation at http://www.airspayce.com/mikem/arduino/RadioHead

RadioHead consists of 2 main sets of classes: Drivers and Managers.
Every RadioHead program will have an instance of a Driver to provide access to the data radio or transport, and usually a Manager that uses that driver to send and receive messages for the application. 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.
