2. In the

Select Kinetis Processor or Board dialog box, select the MCU class or board

the project is using. Then, click

Next.

3. A new project is created. All of the required files are placed in dedicated folders:

board, CMSIS, drivers, source, startup and utilities. For a more detailed

description of the SDK project folder structure, refer to the MCUXpresso 2.x User

Guide.

6.2.5.6 Adding the SIGFOX software driver to the project

This section describes how to add the SIGFOX Software driver to the project.

1. Copy the content of

Sigfox_SDK_SW\SDK_SW_Driver to the source folder in the

newly created project.

2. In main.c, add the include statement highlighted in the figure below to enable the code

to access the SIGFOX software driver.

6.2.5.7 Setting up the project

Once the new project has been created and the SIGFOX software driver has been

added into it, the project must be set up. See Section 6.2.4 "The SIGFOX software

driver", which describes the driver's capabilities and what must be done to configure its

properties.

1. In order to get the SIGFOX software driver to run on the selected MCU, the user must

edit the board/pin_mux.c file to configure the SPI and GPIO pins being used. This

entails making the correct MCU pin selections (see Section 6.2.3 "Supported MCUs")

and then muxing them as needed. Use one of the example projects as a template for

this step. See the figure below.

2. In the file aml/common_aml.h, set the SDK_VERSION macro to SDK_KSDK

(MCUXpresso SDK 2.3).

3. In sf/sf_model.h, update the SF_MODEL macro according to the SIGFOX model

being used.

4. Create a variable of type sf_drv_data_t that will be passed to all used functions.

This variable stores MCU peripheral configuration data and SIGFOX software

driver internal data. This variable must be accessible during run-time and should be

declared either in the main() function or as a global variable.

5. Configure the SPI and pin settings in the driver configuration structure.

6. Set up the MCU peripherals that will be used by the SIGFOX software driver. There

are two options:

• Use the provided SF_SetupSPI() and SF_SetupGPIOs() functions, which will do the

necessary configuration.

• Code the peripheral initialization without using the provided functions.

In either case, the configuration structure must be modified to indicate the instances of

utilized peripherals.

7. Call the SIGFOX initialization function. The initialization function must be passed the

references to the already configured MCU peripherals, which is part of the driver data

structure, and the user configuration of the device itself.

6.2.5.8 Writing application code

All application code must reside in the source folder in the project directory. The code in

main.c may be modified but the original comments related to usage directions should be

retained.
