+ 
+// VERY DRAFT CODE! Needs serious rework/refactoring 
+ 
+/* Introduction
+ * ------------
+ * SD and MMC cards support a number of interfaces, but common to them all
+ * is one based on SPI. This is the one I'm implmenting because it means
+ * it is much more portable even though not so performant, and we already 
+ * have the mbed SPI Interface!
+ *
+ * The main reference I'm using is Chapter 7, "SPI Mode" of: 
+ *  http://www.sdcard.org/developers/tech/sdcard/pls/Simplified_Physical_Layer_Spec.pdf
+ *
+ * SPI Startup
+ * -----------
+ * The SD card powers up in SD mode. The SPI interface mode is selected by
+ * asserting CS low and sending the reset command (CMD0). The card will 
+ * respond with a (R1) response.
+ *
+ * CMD8 is optionally sent to determine the voltage range supported, and 
+ * indirectly determine whether it is a version 1.x SD/non-SD card or 
+ * version 2.x. I'll just ignore this for now.
+ *
+ * ACMD41 is repeatedly issued to initialise the card, until "in idle"
+ * (bit 0) of the R1 response goes to '0', indicating it is initialised.
+ *
+ * You should also indicate whether the host supports High Capicity cards,
+ * and check whether the card is high capacity - i'll also ignore this
+ *
+ * SPI Protocol
+ * ------------
+ * The SD SPI protocol is based on transactions made up of 8-bit words, with
+ * the host starting every bus transaction by asserting the CS signal low. The
+ * card always responds to commands, data blocks and errors.
+ * 
+ * The protocol supports a CRC, but by default it is off (except for the 
+ * first reset CMD0, where the CRC can just be pre-calculated, and CMD8)
+ * I'll leave the CRC off I think! 
+ * 
+ * Standard capacity cards have variable data block sizes, whereas High 
+ * Capacity cards fix the size of data block to 512 bytes. I'll therefore
+ * just always use the Standard Capacity cards with a block size of 512 bytes.
+ * This is set with CMD16.
+ *
+ * You can read and write single blocks (CMD17, CMD25) or multiple blocks 
+ * (CMD18, CMD25). For simplicity, I'll just use single block accesses. When
+ * the card gets a read command, it responds with a response token, and then 
+ * a data token or an error.
+ * 
+ * SPI Command Format
+ * ------------------
+ * Commands are 6-bytes long, containing the command, 32-bit argument, and CRC.
+ *
+ * +---------------+------------+------------+-----------+----------+--------------+
+ * | 01 | cmd[5:0] | arg[31:24] | arg[23:16] | arg[15:8] | arg[7:0] | crc[6:0] | 1 |
+ * +---------------+------------+------------+-----------+----------+--------------+
+ *
+ * As I'm not using CRC, I can fix that byte to what is needed for CMD0 (0x95)
+ *
+ * All Application Specific commands shall be preceded with APP_CMD (CMD55).
+ *
+ * SPI Response Format
+ * -------------------
+ * The main response format (R1) is a status byte (normally zero). Key flags:
+ *  idle - 1 if the card is in an idle state/initialising 
+ *  cmd  - 1 if an illegal command code was detected
+ *
+ *    +-------------------------------------------------+
+ * R1 | 0 | arg | addr | seq | crc | cmd | erase | idle |
+ *    +-------------------------------------------------+
+ *
+ * R1b is the same, except it is followed by a busy signal (zeros) until
+ * the first non-zero byte when it is ready again.
+ *
+ * Data Response Token
+ * -------------------
+ * Every data block written to the card is acknowledged by a byte 
+ * response token
+ *
+ * +----------------------+
+ * | xxx | 0 | status | 1 |
+ * +----------------------+
+ *              010 - OK!
+ *              101 - CRC Error
+ *              110 - Write Error
+ *
+ * Single Block Read and Write
+ * ---------------------------
+ *
+ * Block transfers have a byte header, followed by the data, followed
+ * by a 16-bit CRC. In our case, the data will always be 512 bytes.
+ *  
+ * +------+---------+---------+- -  - -+---------+-----------+----------+
+ * | 0xFE | data[0] | data[1] |        | data[n] | crc[15:8] | crc[7:0] | 
+ * +------+---------+---------+- -  - -+---------+-----------+----------+

+Move finished tasks to Done section:
+
+TODOs:
+- add support for Linux - add sx1276-Linux-hal.h/cpp
+- Add support to provide the send/receive packet buffer,
+  no need to allocate packet data in the sx1276 driver. Can be provided
+  Rx/Tx parameters, this avoids double memory usage
+- Add support for larger Lora packets (can be up to 2048 bytes)
+  this feature is not so important, however the current implementation
+  is very basic.
+- It is a little bit strange that RX/TX/Cad Timeout Timer calling the
+  some handler OnTimeoutIrq. Maybe we just need a single timer, or 
+  it is a good idea to split the OnTimeoutIrq function into separate
+  callbacks for RX/TX/Cad timeouts
+- Test if the SX1276 timeouts. Does rx/tx/sync really uses three different
+  timers or just one at a time.
+- Add API to set the LNA gain
+ 
+
+
+Done:
+- Started a Generic SX1276 driver to support all SX1276 modules (May-2017 Helmut)
+- Migrated typedefs code into sx1276.h (7-May-2017 Helmut)
+- Migrated enum code into sx1276.h/radio.h (7-May-2017 Helmut)
+- Verify the Murata ANT Switch code
+- MURATA PA_BOOST case,is _antSwitchTXBoost right? (Same as STM sample code)
+- Check of the MURATA TCXO config is correct (implemented, check JP9 on STM L0 board)
+- Make the timers more generic and move the OS code into the HAL layer. (May 2017 Helmut)
+- Removed pull down on dio=-dio5 for L151 &LPC11U6X which make no sense to me. May 2017 Helmut
+- Added radio API support to receive the MaxMTUSize (May 2017 Helmut)
+- Added Send optional Send() parameter to include a header,
+  this saves additional buffers. (May 2017 Helmut)
+- Added proper void * type from sending data, uint8_t * is not appropriate (May 2017 Helmut)
+- Use also void pointer for FiFo Write/Read and regular SPI Read/Write
+- Added return value to Init, we check for a radio availability (May 2017 Helmut)
+- Added a RxSignalPending which verifies if we have a signal pending in receive state. (May 2017 Helmut)
+- Added LoRa bandwidth mapping table, now the SetRx/Tx frequency is in Hz. (May 2017 Helmut)
+- Enabled MURATA_SX1276 for the MURATA_SX1276 chip (May 2017 Helmut)
+- Made SetRfTxPower public to allow easily power TX changes (May 2017 Helmut)
+- Added userData and userThisPtr into the radio events, this allows to call C++ 
+  functions and in can include a context via the userData
+- Add support for Cad detection before sending a packet, already done in higher 
+  level protocols
+- Added initial Arduino support, needs more testing/completion.
+- Support for Arduino completed, initial version works.
+- Added GetFrequency support
+  The Murata’s Frequency shift using an TCXO us about 58 Hz
+  The RFM95 against Murata is about 3300 Hz
+  RFM95 against RFM95 testing will follow.

+# SX1276Generic Driver
+/*
+* (c) 2017 Helmut Tschemernjak (Helmut64 on mbed).
+* 30826 Garbsen (Hannover) Germany
+*/
+
+This library represents a common SX1276 module driver supporting SX1276
+based modules. The approach is to support multiple OS versions including
+mbed, Arduino and Linux using the same driver code and little
+adjustments for the different OS version. The SX1276 driver is based on
+the Semtech 1276 code which can be seen in the revisions of this library
+repository.
+
+## Supported LoRa Modules
+
+The following Lora modules are supported:
+- HopeRF RFM95
+- Murata MURATA_SX1276 (CMWX1ZZABZ-078, used the STM B_L072Z_LRWAN1 board)
+- SX1276MB1MAS (433, 868 MHz version)
+- SX1276MB1LAS (433, 915 MHz version)
+
+## Getting Started for Developers
+Import the mbed sample project:
+http://developer.mbed.org/users/Helmut64/code/STM32L0_LoRa
+- It includes a PingPong sample code
+- It includes a PinMap.h which allows to define the LoRa SPI,
+DIO interrupt, reset and antenna pins.
+The STM32L0_LoRa is a turnkey sample application for the STM B_L072Z_LRWAN1,
+however it will work with all other mbed based boards by adjusting the PinMap.h
+
+## Developers help needed
+A list of tasks is documented in the file: LoRa_TODO.txt
+I (Helmut Tschemernjak) spend a very significant time to complete the
+initial version of the SX1276Generic packet driver. Enhancements,
+further module support and tuning is more than welcome. Please send me
+your patches via mbed. Also questions can be submitted in the mbed
+“Questions” area or a personal message via mbed.
+
+## Future developments
+I work in a advanced private protocol using basic LoRa modules to
+communicate between simple nodes (battery powered) and stations
+(permanent power). The station should support thousands of nodes running
+on an Linux based OS using this 1276Generic driver or the LoRa
+concentrator module. The station should also work on mbed or Arduino
+assuming sufficient memory is provided. I believe there is an
+opportunity to do a better protocol compared to the official LoRa
+protocol which requires an Concentrator, a LoRa server and an
+application server. The idea is to over only efficient, reliable and
+secure communication between the nodes and the stations. Further
+forwarding to MQTT and other network services can be handled separately
+on the station.
