In this tutorial we will see how to setup ARM GCC Tool Chain to generate .hex and .bin file for LPC1768.<br>
To start with you will require ARM GCC, winAvr and make utility, download all the software's from following links.<br><br>


=Downloads=
[https://launchpad.net/gcc-arm-embedded ARM GCC]<br>
[https://sourceforge.net/projects/winavr/files/ WinAvr]<br>
[http://gnuwin32.sourceforge.net/packages/make.htm Make Utility]<br><br>

=Installing ARM GCC=
Once ARM GCC is downloaded install it on your machine. At the End of the installation do select the option '''Add path to environment variable''' as shown below.

To test the ARM GCC open the command line and use command '''arm-none-eabi-gcc -v''', which will give the version information as shown below.

=Installing WinAvr=
Run the winavr installer to Install winavr. Follow the installer steps to set the default configuration.


=Installing Make Utility=
Finally install the make utility.<br>
Make utility will not update the path variables and it needs to be done manually.
Add the Make Utility path to the environment path.

Now type the command make -v to verify the path. <br>
Output of the command should be the version number of make file as shown in below image.

=Procedure=
We will compile a simple Led Blinking program for LPC1768 using ARM GCC using following procedure
#There are different ways to access your files depending on the makefile. We can write makefile as per our folder structure and where we are storing different files. As per the makefile we are using make one folder in your local directory where you will store all your source and header files
#Along with the makefile, main and all other library files, keep all following files in this folder
           Core Support: core_cm3.c, core_cm3.h, core_cm3.o

           Device Support: system_LPC17xx.c, system_LPC17xx.h, lpc17xx.h

           Startup file: startup_LPC17xx.c

           Linker Script: LPC17xx.ld
#You can get all these files from [https://github.com/ExploreEmbedded/Explore-Cortex-M3-LPC1768-DVB-14001/tree/master/Code/ARM_GCC/Led_Blinking_GCC Github]

#After that open command line in your local directory and compile program by using <b>make Clean</b> followed by <b>make all</b> command.

#After compilation is over hex and bin file gets generated which can be flashed to our LPC1768 board directly.
