- Adjusted spi writes (delay vs no delay)
- Re-enabled buffer flushes on start/stop listening
- Adjusted delay for transfernb()
- Testing indicates that with gettingstarted_call_response example, ack
responses may not be written soon enough if CPU load is high on RPi. eg:
testing indicates this is a limitation of the hardware, not the driver.

- Moved printf.h to root library folder
- Modified printf.h for better compatibility with Arduino Due and Teensy
- Fixed some potential bugs preventing Teensy from working
- Improved Due support and performance
- may help correct issue #7

- moved radio.flush_tx(); to public
- adjusted call_response example to use tx_flush();
- adjusted write_payload, read_payload

- added delays to stop/start listening on RPi
- removed buffer flushes on start/stop listening for RPi
- added modified transfernbd function to BCM library - one has no
delays, also removed one delay period from both by waiting for RX data
- modified transfernb function to stop sending if RX fifo is full
- added delay to stoplistening for arduino etc. (actually seems to
improve performance)
- tests on-par with Arduino performance

- Added _BV define for Due
- adjusted defines

- Adjusted define in RF24_Config.h for teensy
- Teensy doesn't seem to support extended SPI methods, may not perform
as well as on Due
- Currently compiles, but is untested with teensy

- Changed from using reinterpret cast to memcpy for storing pipe0
address

Updated examples to use proper include path

https://github.com/TMRh20/RF24/issues/6

- Added setAddressWidth()  - allows address widths of 3 to 5 bytes
(24,32 or 40 bits)
- Addresses can now be specified via a byte array
- Thanks to Zephyrr for suggestion

Since RPi behaves more like a PC than Arduino, users should be able to
execute various programs without powering down the radio module, where
an Arduino needs to be re-programmed between code changes, so a full
power-down is not such a dramatic step.

Makefile fixes

Restore closeReadingPipe merge for mysensors

Restore closeReadingPipe to be compatible with mysensors

- Enabled use of hardware CS1 pin
- Removed custom_cs code for software driven CSN
- Modified BCM driver to allow use of hardware SPI pins not in use while
SPI is active.
- Updated constructor in examples

Added support for hardware SPI on RPI per jscrane fork:
- Fixed a few bugs with single SPI transfers
- Aligned with optimized RF24 library fork
- Updated bmc2835 files per
http://www.airspayce.com/mikem/bcm2835/index.html
- Merged bcm files with changes from
https://github.com/farconada/RF24Network
- Added example files
- Added setup info to readme

- fixed mistake with changes to setPALevel prior to pushing

- Using status register is faster to read TX FIFO status - Zephyrr (GitHub)
- Fixed typo on FLUSH_RX cmd
- Added support for pwr levels on SI24R1 chips with smaller code

- Updated some example files and tests
- Small changes to minimize code size

For nRF24L01+ to go from power down mode to TX or RX mode it must first
pass through stand-by mode.
There must be a delay of Tpd2stby (see Table 16.) after the nRF24L01+
leaves power down mode before
the CEis set high.

5ms is the maximum defined in the v1.0 datasheet

- Added new function: enableDynamicAck()  to enable single-write NOACK
payloads (merge closer with gcopeland fork)
- Added single NOACK writes for write(), writeFast(), startWrite() and
startFastWrite()
- powerUp() now checks to see if radio is powered on. No delay if
powered up.
- radio must still be powered up manually if powered down manually
- use setRetries function in begin()
- set CE low on powerDown
- updated readme

ATTiny support pulled in from https://github.com/jscrane/RF24
- SPI support for ATTiny is included with the library. Do NOT include
SPI.h with tiny.

Pin info etc can be found at:
http://programmablehardware.blogspot.ca/2013/09/rf24-with-attiny84.html

ATTiny 85 Example:
RF24 radio(4,3);    // CE: 4  CS: 3

Merge improved write_payload() and read_payload()  - looks good and passes my testing.

Restructured based on needing or not needing blank padding

Found that Due would send multiple payloads or fail in writing in some
cases. Change ensures single-payload transmission using write().
- Updated pingpair_dyn.ino example sketch to conform with available()
changes
- Slight doc update

- SPI transfer fix to read every available byte in the payload with
payloads less than 32 bytes with dynamic payload size disabled.

- Tested and now fully functional on Arduino Due
- Added support for the extended SPI functions: brings Due performance
up to par with Due managing the CSN   pin and settings
- Corrected issues with printDetails() on Due
- Changed added variables to staticly defined types: ie: uint16_t
instead of unsigned int
- I think this will work on all ARM based boards that use the Arduino
libs
- Added maskIRQ function - to be used in RF24Network sleep mode
- Changed csn(int mode) to csn(bool mode)
- Updated GettingStarted_CallResponse.ino example: Capture start time
AFTER printing to serial so measurement is more accurate

- Found I could create a hang condition on startup with some code.
a: Now power up the radio on begin() to simplify things
b: Increase delay to 5ms for powerUp, although it should only take 2ms
tops, this prevents the hanging condition.

- Initial support for Due and ATTiny boards
- Fix for 0 timeout period causing hang
- Remove unnecessary delays from startWrite
- Cleaned up/Updated example files
- Optimization is nearing completion

- For use in noisy or low signal scenarios
- Allows user specified timeout period of extended duration
- Modified txStandBy() and writeBlocking() functions to rely on a user
defined timeout period, automatic retries and payload reUse

for use in wireless audio sketch, needed to move startWrite() to a
public function
