// Supports RF24/RF26 and RFM24/RFM26 modules in FIFO mode
// also Si4464/63/62/61/60-A1
// Si4063 is the same but Tx only
//
// Per http://www.hoperf.cn/upload/rf/RFM24.pdf
// and http://www.hoperf.cn/upload/rf/RFM26.pdf
// Sigh: the HopeRF documentation is utter rubbish: full of errors and incomplete. The Si446x docs are better:

/////////////////////////////////////////////////////////////////////
/// \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
///
/// \par Connecting RFM-24 to Arduino
///
/// For RFM24/RFM26 and Teensy 3.1 or Anarduino Mini
/// \code
/// Teensy RFM-24/RFM26
/// GND----------GND (ground in)
/// 3V3----------VCC (3.3V in)
/// interrupt 2 pin D2-----------NIRQ (interrupt request out)
/// SS pin D10----------NSEL (chip select in)
/// SCK pin D13----------SCK (SPI clock in)
/// MOSI pin D11----------SDI (SPI Data in)
/// MISO pin D12----------SDO (SPI data out)
/// D9-----------SDN (shutdown in)
/// /--GPIO0 (GPIO0 out to control transmitter antenna TX_ANT)
/// \--TX_ANT (TX antenna control in) RFM22B only
/// /--GPIO1 (GPIO1 out to control receiver antenna RX_ANT)
/// \--RX_ANT (RX antenna control in) RFM22B only
/// \endcode
/// 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,
/// which has no antenna switch.
///
/// \par Customising
///
/// The library will work out of the box with the provided examples, over the full frequency range and with
/// 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()
///
/// \par RSSI
///
/// 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
/// The units of RSSI are arbitrary and relative, with larger unsigned numbers indicating a stronger signal. Values up to 255
/// are seen with radios in close proximity to each other. Lower limit of receivable strength is about 70.
///
/// \par Transmitter Power
///
/// You can control the transmitter power on the RF24/25/26/27 transceiver
/// with the RH_RF24::setTxPower() function. The argument can be any of
/// 0x00 to 0x4f (for RFM24/Si4460) or
/// 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);
/// \endcode
///
/// We have made some actual power measurements against
/// programmed power
/// - Anarduino Mini with RFM24-433 and RFM26-433 at Vcc = 3.3V, in CW mode, 434MHz
/// - 10cm RG58C/U soldered direct to RFM69 module ANT and GND
/// - bnc connecteor
/// - 12dB attenuator
/// - BNC-SMA adapter
/// - MiniKits AD8307 HF/VHF Power Head (calibrated against Rohde&Schwartz 806.2020 test set)
/// - Digitech QM-1460 digital multimeter
/// \code
/// Program power Measured Power dBm
/// HEX RFM24 RFM26
/// 0x00 not measurable not measurable
/// 0x01 -20.4 -20.6
/// 0x0f 2.4 4.8
/// 0x1f 9.4 11.0
/// 0x2f 11.2 14.2
/// 0x3f 11.6 16.4
/// 0x4f 11.6 18.0
/// 0x5f 18.6
/// 0x6f 19.0
/// 0x7f 19.2
/// \endcode
/// Caution: the actual radiated power output will depend heavily on the power supply voltage and the antenna.
