/// RH_ASK works with ATTiny85, using Arduino 1.0.5 and tinycore from
/// https://code.google.com/p/arduino-tiny/downloads/detail?name=arduino-tiny-0100-0018.zip
/// Tested with the examples ask_transmitter and ask_receiver on ATTiny85.
/// Caution: The RAM memory requirements on an ATTiny85 are *very* tight. Even the bare bones
/// ask_transmitter sketch barely fits in eh RAM available on the ATTiny85. Its unlikely to work on
/// smaller ATTinys such as the ATTiny45 etc. If you have wierd behaviour, consider
/// reducing the size of RH_ASK_MAX_PAYLOAD_LEN to the minimum you can work with.
/// Caution: the default internal clock speed on an ATTiny85 is 1MHz. You MUST set the internal clock speed
/// to 8MHz. You can do this with Arduino IDE, tineycore and ArduinoISP by setting the board type to "ATtiny85@8MHz',
/// setting theProgrammer to 'Arduino as ISP' and selecting Tools->Burn Bootloader. This does not actually burn a
/// bootloader into the tiny, it just changes the fuses so the chip runs at 8MHz.
/// If you run the chip at 1MHz, you will get RK_ASK speeds 1/8th of the expected.
///
/// Initialise RH_ASK for ATTiny85 like this:
/// // #include <SPI.h> // comment this out, not needed
/// RH_ASK driver(2000, 4, 3); // 200bps, TX on D3 (pin 2), RX on D4 (pin 3)
/// then:
/// Connect D3 (pin 2) as the output to the transmitter
/// Connect D4 (pin 3) as the input from the receiver.
///
///
/// For testing purposes you can connect 2 Arduino RH_ASK instances directly, by
/// connecting pin 12 of one to 11 of the other and vice versa, like this for a duplex connection:
///
/// \code
/// Arduino 1 wires Arduino 1
/// D11-----------------------------D12
/// D12-----------------------------D11
/// GND-----------------------------GND
/// \endcode
///
/// You can also connect 2 RH_ASK instances over a suitable analog
/// transmitter/receiver, such as the audio channel of an A/V transmitter/receiver. You may need
/// buffers at each end of the connection to convert the 0-5V digital output to a suitable analog voltage.
///
/// Measured power output from RFM85 at 5V was 18dBm.
