-RadioHead Packet Radio library for embedded microprocessors
-===========================================================
-
-This is a fork of the original RadioHead Packet Radio library for embedded microprocessors. It provides a complete object-oriented library for sending and receiving packetized messages via a variety of common data radios and other transports on a range of embedded microprocessors.
-
-**Please read the full documentation and licensing from the original author [site][3]**
-
-### features added with this fork
-=================================
-
-**Compatible with boards**    
-
-[LoRasPI][10], [Raspberry PI Lora Gateway][12], [Dragino Lora GPS HAT][13]

-- Added moteino modem setting on RF69 to be compatible with lowpowerlab RF69 configuration library
-- Added possibility to work with no IRQ connected for RF69 and RF95
-  - for example to get one more GPIO free 
-  - on Raspberry Pi, we do not have `attachInterrupt()` like with bcm2835 library
-- Added samples for multiples Raspberry Pi boards with RF69 and RF95 modules such as 
-  - [LoRasPI][10], simple RFM9x or RFM69HCW shield
-  - [iC880A or Linklabs Raspberry PI shield][11] with RFM9x or RFM69HCW onboard 
-  - [Raspberry PI Lora Gateway][12] with multiple RFM9x or RFM69HCW shield
-  - [Dragino Lora shield][13]
-  - Sample code are in [rf95][21], [rf69][20], [nrf24][22] and [multi_server][23], note that old sample NRF24 sample has been moved to nrf24 folder for consistency.
-- Added 2 samples test tools (for Raspberry PI) do detect RF69 and RF95 modules and check IRQ rising edge
-  - [spi_scan][9] sample code, scan and try to detect connected modules
-  - [irq_test][8] sample code, check a rising edge on a GPIO
-
-Sample code for Raspberry PI is located under [RadioHead/examples/raspi][7] folder.
-
-### Installation on Raspberry PI
-================================
-
-Clone repository
-```shell
-git clone https://github.com/hallard/RadioHead
-```
-
-**Connection and pins definition**
-
-Boards pins (Chip Select, IRQ line, Reset and LED) definition are set in the new [RadioHead/examples/raspi/RasPiBoards.h][24] file. In your code, you need to define board used and then, include the file definition like this
-```cpp
-// LoRasPi board 
-#define BOARD_LORASPI
-
-// Now we include RasPi_Boards.h so this will expose defined 
-// constants with CS/IRQ/RESET/on board LED pins definition
-#include "../RasPiBoards.h"
-
-// Your code start here
-#ifdef RF_RST_PIN
-// Blah blah do reset line
-#endif
-
-```
-
-Then in your code you'll have exposed RF_CS_PIN, RF_IRQ_PIN, RF_RST_PIN and RF_LED_PIN and you'll be able to do some `#ifdef RF_LED_LIN` for example. See [rf95_client][25] sample code.
-
-So you have 3 options to define the pins you want 
-
-- The board you have is already defined so just need to define it your source code (as explained above)
-- You can add your board into [RasPiBoards.h][24] and then define it your source code as above
-- You can manually define pins in your code and remove the board definition and `#include "../RasPiBoards.h"`
-
-To go further with examples :
-
-go to example folder here spi_scan
-```shell
-cd RadioHead/examples/raspi/spi_scan
-```
-Build executable
-```shell
-root@pi03(rw):~/RadioHead/examples/raspi/spi_scan# make
-g++ -DRASPBERRY_PI -DBCM2835_NO_DELAY_COMPATIBILITY -c -I../../.. spi_scan.c
-g++ spi_scan.o -lbcm2835  -o spi_scan
-root@pi03(rw):~/RadioHead/examples/raspi/spi_scan
-```
-And run 
-```shell
-root@pi03(rw):~/RadioHead/examples/raspi/spi_scan# ./spi_scan
-Checking register(0x42) with CS=GPIO06 => Nothing!
-Checking register(0x10) with CS=GPIO06 => Nothing!
-Checking register(0x42) with CS=GPIO08 => SX1276 RF95/96 (V=0x12)
-Checking register(0x10) with CS=GPIO08 => Nothing!
-Checking register(0x42) with CS=GPIO07 => Nothing!
-Checking register(0x10) with CS=GPIO07 => Nothing!
-Checking register(0x42) with CS=GPIO26 => Nothing!
-Checking register(0x10) with CS=GPIO26 => Nothing!
-```
-And voila! with [LoRasPi][10] board RFM95 dedected on SPI with GPIO8 (CE0)
-
-
-If I'm doing same test with [PI Lora Gateway][12] with 2 RFM95 (one 433MHz and one 868MHz) and one RFMHW69 433MHz on board like this    
-
-<img src="https://raw.githubusercontent.com/hallard/RPI-Lora-Gateway/master/images/RPI-Lora-Gateway-mounted.jpg" height="40%" width="40%" alt="Raspberry PI Lora Gateway/Node">   
-
-Here are the results when trying to detect the onboard modules:
-
-```shell
-root@pi01(rw):~/RadioHead/examples/raspi/spi_scan# ./spi_scan
-Checking register(0x42) with CS=GPIO06 => Nothing!
-Checking register(0x10) with CS=GPIO06 => Nothing!
-Checking register(0x42) with CS=GPIO08 => SX1276 RF95/96 (V=0x12)
-Checking register(0x10) with CS=GPIO08 => Nothing!
-Checking register(0x42) with CS=GPIO07 => SX1276 RF95/96 (V=0x12)
-Checking register(0x10) with CS=GPIO07 => Nothing!
-Checking register(0x42) with CS=GPIO26 => Unknown (V=0x01)
-Checking register(0x10) with CS=GPIO26 => SX1231 RFM69 (V=0x24)
-```
-
-Voila! 3 modules are seen, now let's try listenning packets with PI Lora [Gateway][12].
-
-My setup has another Raspberry Pi with RFM95 868MHZ [LoRasPI][10] shield running [`rf95_client`][25] sample and some [ULPnode][6] prototypes always running with on board RFM69 configured as Group ID 69 on 433MHz. I don't have a Lora 433MHz sender running so we won't receive anything on this one.
-
-Here the results starting from scratch
-
-**Client side**    
-
-<img src="https://raw.githubusercontent.com/hallard/RadioHead/master/examples/raspi/pictures/rf95_client.png" alt="RF95 client">

-**multi server side**

-
-It works!

-### Difference with original Author repo
-========================================
-
-Due to easier maintenance to keep in sync with original author lib, I've got 2 repo:    
-
-- My master one (this one) https://github.com/hallard/RadioHead that is the one you need if you want to use my projects or lib added features.
--  The one above has been forked to https://github.com/ch2i/RadioHead where I put the original version released by the author.
-
-Like this, I can do Pull Request from [ch2i][4] to [hallard][1] to add new features added by the author to my version. This mean that this [one][4] is just a github copy version of the latest original done by Mike, I don't do any change on this one. I know it's not the best way, but I didn't found a better solution for now, if you have better idea, just let me know.
