h1. Compiling from source
It is possible to compile the software from source and make a binary image that runs on the mbed. There are 3 methods:
# With MBED online compiler (at http://mbed.org): You need an account on mbed.org and a Internet connection.
# With gcc4mbed offline compiler, using GCC. Download at (https://github.com/adamgreen/gcc4mbed)
# With open source MBED from GitHub (recommended method). GitHub.
h2. With 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 (mbed-gcc branch):
<pre>git clone --recursive https://github.com/LaosLaser/Firmware.git -b mbed-gcc</pre>
Optional, maybe not necessary: update mbed libs: libs
<pre>cd Firmware/mbed
git Firmware/mbed</pre>
<pre>git pull origin master</pre>
or from elsewhere
<pre>git pull https://github.com/pbrier/mbed master</pre>
Patch mbed libraries:
<pre>cd mbed/
patch -p1 < ../laser/mbed.patch</pre>
Download _GCC ARM_ from the following address and place it in a folder
_https://launchpad.net/gcc-arm-embedded/+download_
Copy _Firmware/mbed/workspace_tools/settings.py_ to _Firmware/mbed/workspace_tools/private_settings.py_.
Update the _GCC_ARM_PATH_ path in _private_settings.py_ to 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>
Link LaOSlaser as an mbed example project
<pre>cd libraries/tests/net/protocols/</pre>
<pre>ln -s ../../../../../laser</pre>
Compiling the firmware:
<pre>cd ../../../../</pre>
<pre>python workspace_tools/make.py -m LPC1768 -t GCC_ARM -n laser</pre>
Then you should be able to find your new firmware at:
_Firmware/mbed/build/test/LPC1768/GCC_ARM/laser/laser.bin_
Read http://mbed.org/handbook/mbed-tools for more info
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.
