/// \class RH_RF24 RH_RF24.h <RH_RF24.h>
|
|
/// \brief Driver to send and receive unaddressed, unreliable datagrams via an RF24 and compatible radio transceiver.
|
|
///
|
|
/// Works with
|
|
/// - Silicon Labs Si4460/1/2/3/4 transceiver chips
|
|
/// - The equivalent HopeRF RF24/25/26/27 transceiver chips
|
|
/// - HopeRF Complete modules: RFM24W/26W/27W
|
|
///
|
|
/// \par Overview
|
|
///
|
|
/// This class provides basic functions for sending and receiving unaddressed,
|
|
/// unreliable datagrams of arbitrary length to 250 octets per packet.
|
|
///
|
|
/// Manager classes may use this class to implement reliable, addressed datagrams and streams,
|
|
/// mesh routers, repeaters, translators etc.
|
|
///
|
|
/// Naturally, for any 2 radios to communicate that must be configured to use the same frequency and
|
|
/// modulation scheme.
|
|
///
|
|
/// This Driver provides an object-oriented interface for sending and receiving data messages with Hope-RF
|
|
/// RF24 and compatible radio modules, such as the RFM24W module.
|
|
///
|
|
/// The Hope-RF (http://www.hoperf.com) RF24 family is a low-cost ISM transceiver
|
|
/// chip. It supports FSK, GFSK, OOK over a wide range of frequencies and
|
|
/// programmable data rates. HopeRF also sell these chips on modules which includes
|
|
/// a crystal and antenna coupling circuits: RFM24W, RFM26W and RFM27W
|
|
///
|
|
/// This Driver provides functions for sending and receiving messages of up
|
|
/// to 250 octets on any frequency supported by the RF24, in a range of
|
|
/// predefined data rates and frequency deviations. Frequency can be set
|
|
/// to any frequency from 142.0MHz to 1050.0MHz. Caution: most modules only support a more limited
|
|
/// range of frequencies due to antenna tuning.
|
|
///
|
|
/// Up to 2 RFM24 modules can be connected to an Arduino (3 on a Mega),
|
|
/// permitting the construction of translators and frequency changers, etc.
|
|
///
|
|
/// The following modulation types are suppported with a range of modem configurations for
|
|
/// common data rates and frequency deviations:
|
|
/// - OOK On-Off Keying
|
|
/// - GFSK Gaussian Frequency Shift Keying
|
|
/// - FSK Frequency Shift Keying
|
|
///
|
|
/// Support for other RF24 features such as on-chip temperature measurement,
|
|
/// transmitter power control etc is also provided.
|
|
///
|
|
/// RH_RF24 uses interrupts to detect and handle events in the radio chip. The RF24 family has
|
|
/// TX and RX FIFOs of 64 bytes, but through the use of interrupt, the RH_RF24 driver can send longer
|
|
/// messages by filling or emptying the FIFOs on-the-fly.
|
|
///
|
|
/// Tested on Anarduino Mini http://www.anarduino.com/mini/ with arduino-1.0.5
|
|
/// on OpenSuSE 13.1
|
|
///
|
|
/// \par Packet Format
|
|
///
|
|
/// All messages sent and received by this RH_RF24 Driver conform to this packet format:
|
|
///
|
|
/// - 4 octets PREAMBLE (configurable)
|
|
/// - 2 octets SYNC 0x2d, 0xd4 (configurable, so you can use this as a network filter)
|
|
/// - Field containing 1 octet of message length and 2 octet CRC protecting this field
|
|
/// - Field 2 containing at least 4 octets, and 2 octet CRC protecting this field:
|
|
/// + 4 octets HEADER: (TO, FROM, ID, FLAGS)
|
|
/// + 0 to 250 octets DATA
|
|
/// + 2 octets CRC, computed on HEADER and DATA
|
|
///

/// Caution: tying the radio SDN pin to ground (though it might appear from the data sheets to make sense)

|
/// does not always produce a reliable radio startup. So this driver controls the SDN pin directly.

/// Note: the GPIO0-TX_ANT and GPIO1-RX_ANT connections are not required for the 11dBm RFM24W,

/// If you have an Arduino Zero, you should note that you cannot use Pin 2 for the interrupt line

/// a wide range of predefined modem configurations schemes and speeds. However, you may want to
|
|
/// change the default behaviour of this library. There are several ways you can do this:
|
|
///
|
|
/// - Use the RH_RF24 API based on this documentation
|
|
/// - Create your own ModemConfig and pass it to setModemreeegisters()
|
|
/// - Generate a new radio_config_Si4460.h using the Silicon Labs WDS software package
|
|
/// - Write directly to the radio registers and properties using command() and set_properties()

/// The RSSI (Received Signal Strength Indicator) is measured and latched after the message sync bytes are received.
|
|
/// The latched RSSI is available from the lastRssi() member functionafter the complete message is received.
|
|
/// Although lastRssi()
|
|
/// supposedly returns a signed integer, in the case of this radio it actually returns an unsigned 8 bit integer (uint8_t)
|

/// and you will have to cast the return value to use it:
|
|
/// \code
|
|
/// uint8_t lastRssi = (uint8_t)rf24.lastRssi();
|
|
/// \endcode
|
|

|
|
///

|
/// 0x00 to 0x7f (for others)
|
|
/// 0x00 will yield no measurable power. For other settings there is a non-linear correlation with actual
|
|
/// RF power output (see below)
|
|
/// The default is 0x10. Eg:

/// \code

/// driver.setTxPower(0x10);
