GitLab

- 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

- Update littlewire makefile by @lnxbil for new hardware support
template

- Update main Makefile (CCFLAGS)
- Update examples_RPi Makefile (CCFLAGS)
- Update examples_RPi/gettingstarted.cpp with BBB/spidev pins example

https://github.com/TMRh20/RF24/commit/e2abd640a296e1be9b2abc0d27bbd5caa1affa78#commitcomment-9750201

Move to new template for:
- RPi (BCM2835)
- BBB (SPI_DEV)
- LittleWire

RPi can be forced to use SPIDEV by calling "sudo make install
RF24_SPIDEV=1"

Potential RPi 2 support via updated bcm2835.c (version 1.39)

- Created the appropriate files for Due and ATTiny under arch/Due and
arch/ATTiny
- Modify RF24_config.h to suit the new changes
- Modify detection for Arduino Due ( ARDUINO_SAM_DUE )
- Update RF24.cpp for cleaner Due detection

Due changes are tested and working
ATTiny changes compile but are untested

Merge master with updates branch

Some changes to get different revisions of NRF24L01+ modules working. by @dsbaha 

- remove additional toggle_features as already enabled in radio start

Address fix for attiny example sketch

The addresses are reversed when using with the GettingStarted sketch as
described in the comments. This causes the arduino and the tiny to both
be in receiver mode.

adapted python wrapper for RF24 interface changes in txStandBy and startFastWrite by @mz-fuzzy re #64 

Conflicts:
	RPi/pyRF24/pyRF24.cpp

- Add optional values for startFastWrite and txTimeout
#64

- Add optional startTx to startFastWrite() function:
a: Allows software to fully utilize FIFO buffers for buffering payloads
to the TX FIFO, while remaining in RX mode, instead of storing data in
RAM etc.
b: Default is still to start sending immediately unless startTx is
included and set to 0

Note: This will not work correctly if using ack-payloads. Tx FIFO is
flushed when switching between RX/TX modes to prevent data corruption.

- Added optional startTx to txStandBy(timeout,startTx)
a: Allows automated sending of buffered data, with indication of success
or failure for the bulk data transfer.
b: Default is still to not initiate sending, and not leave RX mode.
c: Calling this with startTx set to true will automatically call
radio.stopListening() to begin transmission.

Example:
radio.startFastWrite( &time, sizeof(unsigned long), false );
radio.startFastWrite( &time, sizeof(unsigned long), false );

if (!radio.txStandBy(100, true) ){  printf("failed.\n\r");  }
radio.startListening()

Using the handy hardware/firmware combination LittleWire by Ihsan
Kehribar, you can access the SPI bus on every libusb-capable machine.
This approach is far from fast, but it works for sending or receiving
simple commands.
