simple LoRa example

These added examples are not LoRaWAN, instead they use LoRa transceiver chip directly.

added applications:

-DAPPLICATION="simple-tx"
-DAPPLICATION="simple-rx"
-DAPPLICATION="led-blink" 

added boards:

-DBOARD="NUCLEO-L031K6"
-DBOARD="NUCLEO-G071RB" 
-DBOARD="NUCLEO-G070RB" 
-DBOARD="NUCLEO-G031K8"
-DBOARD="NUCLEO-F446RE"

already existing radio chips:

-DMBED_RADIO_SHIELD="LR1110MB1XXS"
-DMBED_RADIO_SHIELD="SX1262MBXCAS"
-DMBED_RADIO_SHIELD="SX1261MBXBAS"

if you're using STM32L0xx MCU:

in directory src/boards/mcu/stm32:
git submodule update --init STM32CubeL0

or, if you're using STM32L1xx MCU:

in directory src/boards/mcu/stm32:
git submodule update --init STM32CubeL1

or, if you're using STM32L4xx MCU:

in directory src/boards/mcu/stm32:
git submodule update --init STM32CubeL4

or, if you're using STM32G0xx MCU:

in directory src/boards/mcu/stm32:
git submodule update --init STM32CubeG0

or, if you're using STM32F4xx MCU:

in directory src/boards/mcu/stm32:
git submodule update --init STM32CubeF4

if you're using LR1110 radio chip:

in directory src/radio/lr1110:
git submodule update --init lr1110_driver

running cmake

running cmake on windows

create a .ps1 script for running cmake, example to be run from your build directory:

cmake -G Ninja -DCMAKE_BUILD_TYPE=Release `
    -DCMAKE_TOOLCHAIN_FILE="../cmake/toolchain-arm-none-eabi.cmake" `
    -DTOOLCHAIN_PREFIX="C:/Program Files (x86)/GNU Arm Embedded Toolchain/9 2020-q2-update" `
    -DAPPLICATION="simple-tx" `
    -DMBED_RADIO_SHIELD="SX1262MBXCAS" `
    -DUSE_RADIO_DEBUG="ON" `
    -DBOARD="NUCLEO-G071RB" `
 ..

Above example uses ninja generator, if you dont have it, get ninja from https://ninja-build.org/

Recommened to use windows terminal instead of powershell.

If you've never run .ps1 script before, you need to allow them to run.

running cmake on linux

create a .sh script for running cmake, example to be run from your build directory:

cmake -G Ninja -DCMAKE_BUILD_TYPE=Release \
    -DCMAKE_TOOLCHAIN_FILE="../cmake/toolchain-arm-none-eabi.cmake" \
    -DTOOLCHAIN_PREFIX="/home/youruser/gcc-arm-none-eabi-9-2020-q2-update" \
    -DAPPLICATION="simple-tx" \
    -DMBED_RADIO_SHIELD="SX1262MBXCAS" \
    -DUSE_RADIO_DEBUG="ON" \
    -DBOARD="NUCLEO-G071RB" \
 ..

building with IDE

install cmake_ide_generator.

in your build directory, run query-cmake prior to running cmake, then after cmake completes, json will then be present, permitting IDE project files to be generated.

building with stm32CubeIDE

in your build directory run stm32cubeide-parse-reply after running cmake

you will then see .project and .cproject files, which can be imported into IDE as existing project.
