- Per suggestion by @nerdralph use SPI_HAS_TRANSACTION instead of
Arduino version for detection of transaction support

- Remove most Due specific code
- Update remaining SPI code using transaction functions

- Use SPI transactions for 1.6.0 and up

- Temporarily comment changes to begin() pending further testing/dev
- Maintain backwards compatibility by detecting Arduino IDE version

- tmp fix - remove virtual destructor for Arduino etc
- Replace bell with null per #91

- Push fix to updates branch

https://github.com/TMRh20/RF24/pull/83

- Found the prev. method of RPi detection was not working on rasbpmc
- Updated to check for BCM via /proc/cpuinfo  - idea taken from MRAA lib

- Define SPI config vars for non-Arduino systems:
RF24_BIT_ORDER, RF24_DATA_MODE, RF24_CLOCK_DIVIDER
- Allow use of standard RF24 constructor on RPi with default of 8Mhz SPI
clock speed
- Cleanup #ifdefs in RF24::csn();
- Fix compile on ATTiny

- Add BBB pin config to examples per @desertgourd #69
- BBB tested and working well with SPIDEV and MRAA: Thanks to
@desertgourd for all the testing, troubleshooting, etc
- Sync pin config info between all *.cpp examples
- Add links to related documentation in examples

Added ```busNo``` passing to mraa::Spi()... per @prophet-roshak suggestion to SPI.begin chagnes

Added ```busNo``` passing to mraa::Spi() object creation call so that SPI bus number now can be defined by user when instatiating RF24 object

- Add Template folder with example class declarations etc
- Add template info to modules section in doxygen
- Update related links etc for doxygen in RF24.h

- Change SPI API for Linux devices to specify bus number in
SPI.begin(0);
- Enable kernel to handle cs toggling with SPIDEV
- Comment out GPIO for CS pin with MRAA
- Prevent linux devices from toggling CSN in RF24.cpp
- Ensure all linux devices default to 0 or 1 for csn_pin
- Remove some #ifdefs from RF24.cpp via above changes

- Note: When using SPIDEV, if the pin used for CSN has been toggled via
GPIO, users may need to do the following, to enable the kernel to toggle
CSN:
``` sudo modprobe -r spi_bcm2708 ```
``` sudo modprobe spi_bcm2708  ```

- Code needs cleanup/review

#69 #74

- Add Portability section to docs
- Add source file browser to docs
- Filter out GPIO and SPI classes from docs, but include in file lists
- Update doxyfile

- Modify spidev writes for bbb/linux - Something seems to have changed
with spidev with the spi_ioc_transfer struct on my machine. This seems
closer to the spidevtest.c example, so hopefully keeps working???
- Prevent warnings via compatibility.c/.h
- Add spi.begin to align with RF24 spi functions

Inadequate testing appeared to indicate the CRC checking was at fault,
this was incorrect.

Seemed to be 2 separate bugs in transfer example:
Symptoms: Arduino would start reading 150+ KB/s and about 5000
payloads/second received after a period of time with transfers ongoing
continuously.
Fixes:
1. Remove the printf of Payload Count (same issue with %lu )
2. Prevent division into 0

- Move some optional parameters to advanced operation and vice-versa

All documentation to be contained on http://tmrh20.github.io

- Move all documentation out of github.com readmes and onto github.io
pages via source code/doxygen
- Update Transfer example (16-bit CRC)
- Update ATTiny example (pin configuration)
- Add readme files to clarify old/non-updated examples
- Add/Update documentation for various platforms
- Deleted old RPi folder under RF24/RPi/RPi

Beginning of documentation updates for coming changes, and the
consolidation of info from readme into source/doxygen
Still needs lots of work..

MRAA: Updated memory usage

Fixed issue with ARDUINO not issuing CS for radio

- MRAA support originally by @prophet-roshak #74
- Updated to migrate support files completely into arch/MRAA and
minimize changes to the source files
- Changes as per suggestions from @arfoll

- incorrect define prevents dual devices from sharing the SPI BUS
