The deepsleep does not need to disable the SysTick, it is off
already in suspend mode. It looks like out D21 MCU does not
need to keep the flash on during sleep, we got a newer chip
revision.

| Helmut Tschemernjak | 47:ec1183094b71 | 7 | This library represents a common SX1276 module driver supporting SX1276 |
| Helmut Tschemernjak | 47:ec1183094b71 | 8 | based modules. The approach is to support multiple OS versions including |
| Helmut Tschemernjak | 47:ec1183094b71 | 9 | mbed, Arduino and Linux using the same driver code and little |
| Helmut Tschemernjak | 47:ec1183094b71 | 10 | adjustments for the different OS version. The SX1276 driver is based on |
| Helmut Tschemernjak | 47:ec1183094b71 | 11 | the Semtech 1276 code which can be seen in the revisions of this library |
| Helmut Tschemernjak | 47:ec1183094b71 | 12 | repository. |

| Helmut Tschemernjak | 46:e78a1d0391ac | 14 | ## Supported LoRa Modules |
| Helmut Tschemernjak | 46:e78a1d0391ac | 15 | |
| Helmut Tschemernjak | 46:e78a1d0391ac | 16 | The following Lora modules are supported: |
| Helmut Tschemernjak | 46:e78a1d0391ac | 17 | - HopeRF RFM95 |
| Helmut Tschemernjak | 46:e78a1d0391ac | 18 | - Murata MURATA_SX1276 (CMWX1ZZABZ-078, used the STM B_L072Z_LRWAN1 board) |
| Helmut Tschemernjak | 46:e78a1d0391ac | 19 | - SX1276MB1MAS (433, 868 MHz version) |
| Helmut Tschemernjak | 46:e78a1d0391ac | 20 | - SX1276MB1LAS (433, 915 MHz version) |
| Helmut Tschemernjak | 46:e78a1d0391ac | 21 | |
| Helmut Tschemernjak | 46:e78a1d0391ac | 22 | ## Getting Started for Developers |
| Helmut Tschemernjak | 46:e78a1d0391ac | 23 | Import the mbed sample project: |
| Helmut Tschemernjak | 46:e78a1d0391ac | 24 | http://developer.mbed.org/users/Helmut64/code/STM32L0_LoRa |
| Helmut Tschemernjak | 46:e78a1d0391ac | 25 | - It includes a PingPong sample code |
| Helmut Tschemernjak | 46:e78a1d0391ac | 26 | - It includes a PinMap.h which allows to define the LoRa SPI, |
| Helmut Tschemernjak | 47:ec1183094b71 | 27 | DIO interrupt, reset and antenna pins. |
| Helmut Tschemernjak | 47:ec1183094b71 | 28 | The STM32L0_LoRa is a turnkey sample application for the STM B_L072Z_LRWAN1, |
| Helmut Tschemernjak | 47:ec1183094b71 | 29 | however it will work with all other mbed based boards by adjusting the PinMap.h |
| Helmut Tschemernjak | 46:e78a1d0391ac | 30 | |
| Helmut Tschemernjak | 46:e78a1d0391ac | 31 | ## Developers help needed |
| Helmut Tschemernjak | 46:e78a1d0391ac | 32 | A list of tasks is documented in the file: LoRa_TODO.txt |
| Helmut Tschemernjak | 47:ec1183094b71 | 33 | I (Helmut Tschemernjak) spend a very significant time to complete the |
| Helmut Tschemernjak | 47:ec1183094b71 | 34 | initial version of the SX1276Generic packet driver. Enhancements, |
| Helmut Tschemernjak | 47:ec1183094b71 | 35 | further module support and tuning is more than welcome. Please send me |
| Helmut Tschemernjak | 47:ec1183094b71 | 36 | your patches via mbed. Also questions can be submitted in the mbed |
| Helmut Tschemernjak | 47:ec1183094b71 | 37 | “Questions” area or a personal message via mbed. |
| Helmut Tschemernjak | 46:e78a1d0391ac | 38 | |
| Helmut Tschemernjak | 46:e78a1d0391ac | 39 | ## Future developments |
| Helmut Tschemernjak | 47:ec1183094b71 | 40 | I work in a advanced private protocol using basic LoRa modules to |
| Helmut Tschemernjak | 47:ec1183094b71 | 41 | communicate between simple nodes (battery powered) and stations |
| Helmut Tschemernjak | 47:ec1183094b71 | 42 | (permanent power). The station should support thousands of nodes running |
| Helmut Tschemernjak | 47:ec1183094b71 | 43 | on an Linux based OS using this 1276Generic driver or the LoRa |
| Helmut Tschemernjak | 47:ec1183094b71 | 44 | concentrator module. The station should also work on mbed or Arduino |
| Helmut Tschemernjak | 47:ec1183094b71 | 45 | assuming sufficient memory is provided. I believe there is an |
| Helmut Tschemernjak | 47:ec1183094b71 | 46 | opportunity to do a better protocol compared to the official LoRa |
| Helmut Tschemernjak | 47:ec1183094b71 | 47 | protocol which requires an Concentrator, a LoRa server and an |
| Helmut Tschemernjak | 47:ec1183094b71 | 48 | application server. The idea is to over only efficient, reliable and |
| Helmut Tschemernjak | 47:ec1183094b71 | 49 | secure communication between the nodes and the stations. Further |
| Helmut Tschemernjak | 47:ec1183094b71 | 50 | forwarding to MQTT and other network services can be handled separately |
| Helmut Tschemernjak | 47:ec1183094b71 | 51 | on the station. |
