Mini how-to "mbed-os-example-blinky"

You can compile the project using mbed compiler online or locally on your PC.

MBED Compiler on-line

The following steps will show you how to compile the project via browser:

1. Go to the Sensor Node page.

2. Click on the + Add to your Mbed Compiler button.


3. From the mbed-os-example-blinky page click on the Import into the Compiler button.


4. From the following form import the project:


5. Once imported check if you selected the right platform, on the right of the screen you should have this:


If there is another platform please click on it and select the Avnet Silica ST Sensor

6. Now you are able to compile the project just clicking on compile button:


7. After the compilation you will download automatically the firmware


8. Copy the binary file mbed-os-example-blinky.bin into the mass-storage TilePlus of the SensorNode board.


The following steps will show you how to compile the project on your PC:

1. Clone this repository with the command:

$ mbed import https://os.mbed.com/teams/Avnet-Silica/code/mbed-os-example-blinky/


The cloning process requires few minutes.

2. Enter in the directory and compile the project:

$ cd mbed-os-example-blinky
$ mbed compile -m SILICA_SENSOR_NODE -t GCC_ARM

3. Once compiled copy the binary file mbed-os-example-blinky.bin into the mass-storage TilePlus of the SensorNode board.


You will find the mbed-os-example-blinky.bin file at:
"mbed-os-example-blinky\BUILD\SILICA_SENSOR_NODE\GCC_ARM" directory.


Please close with jumpers the following pins marked as yellow in order to power supply the board via micro-usb cable.


In the red rectangles, with this configuration is not important if you have connected the battery and if the switch is closed or open.

# Getting started with Blinky on mbed OS

This guide reviews the steps required to get Blinky working on an mbed OS platform.

Please install [mbed CLI](https://github.com/ARMmbed/mbed-cli#installing-mbed-cli).

## Import the example application

From the command-line, import the example:

mbed import mbed-os-example-blinky
cd mbed-os-example-blinky

### Now compile

Invoke `mbed compile`, and specify the name of your platform and your favorite toolchain (`GCC_ARM`, `ARM`, `IAR`). For example, for the ARM Compiler 5:

mbed compile -m K64F -t ARM

Your PC may take a few minutes to compile your code. At the end, you see the following result:

### Program your board

1. Connect your mbed device to the computer over USB.
1. Copy the binary file to the mbed device.
1. Press the reset button to start the program.

The LED on your platform turns on and off.

## Export the project to Keil MDK, and debug your application

From the command-line, run the following command:

mbed export -m K64F -i uvision

To debug the application:

1. Start uVision.
1. Import the uVision project generated earlier.
1. Compile your application, and generate an `.axf` file.
1. Make sure uVision is configured to debug over CMSIS-DAP (From the Project menu > Options for Target '...' > Debug tab > Use CMSIS-DAP Debugger).
1. Set breakpoints, and start a debug session.

## Troubleshooting

1. Make sure `mbed-cli` is working correctly and its version is `>1.0.0`

 mbed --version

 If not, you can update it:

 pip install mbed-cli --upgrade

2. If using Keil MDK, make sure you have a license installed. [MDK-Lite](http://www.keil.com/arm/mdk.asp) has a 32 KB restriction on code size.
