h1. Compiling from source

h2. With gcc4mbed

It is possible to compile the software from source and make a binary image that runs on the mbed.

# MBED online compiler (at http://mbed.org): You need an account on mbed.org and a Internet connection. 

# GCC4MBED offline compiler, using GCC. Download at (https://github.com/adamgreen/gcc4mbed)

You can use GCC4MBED on your platform, or use a linux virtual machine to compile the sources. See:

http://jeelabs.net/projects/tosca/wiki/ARM_toolchain_setup_GCC4ARM

Installation of gcc4mbed on linux:

<pre>

wget https://github.com/adamgreen/gcc4mbed/zipball/master

mv master adamgreen-gcc4mbed.zip

unzip adamgreen-gcc4mbed.zip

mv adamgreen-gcc4mbed-* gcc4mbed

cd gcc4mbed

./linux_install</pre>

Check the "Github gcc4mbed page":https://github.com/adamgreen/gcc4mbed when you run into problems. 

Then download / clone the firmware

<pre>git clone https://github.com/LaosLaser/Firmware.git</pre>

Place laser folder in gcc4mbed folder

Run the following command in that folder

<pre>make</pre>

And copy the resulting bin file to your MBED or LPC.

The compiler (currently) creates two .bin files. (laos.bin and laos-lpc.bin) laos-LPC is (experimental) for the lpcexpresso (not mbed).

h2. with open source MBED from GitHub

Download the firmware from github:

<pre>git clone --recursive https://github.com/LaosLaser/Firmware.git</pre>

Optional, maybe not necessary: update mbed libs

<pre>cd Firmware/mbed</pre>

<pre>git pull origin master</pre>

or from elsewhere

<pre>git pull https://github.com/pbrier/mbed master</pre>

Download _GCC ARM_ from the following address and place it in a folder

_https://launchpad.net/gcc-arm-embedded/+download_

When necessary update the _GCC_ARM_PATH_ path in _Firmware/mbed/workspace_tools/settings.py_

For example: _/Developer/gcc-arm-none-eabi-4_7-2013q3/bin_ (Make sure you specify the _bin_ folder).

Now, compile the libraries

<pre>python workspace_tools/build.py -m LPC1768 -t GCC_ARM -r -e -u -c</pre>

Compiling the firmware

h1. Debugging

You can debug the MBED by means of a USB/serial connection. This is included in the mbed (no USB/serial adapter required).

See the [[MBED Serial Debugging]] page for more information.
