Hi Guys,
I am very new to the LPCXpresso and ARM and I am trying to make sense of all the fectures of both. I had a look at some of the example programs and on the SCR section of each of them there is always a file called "cr_startup_lpc11.c" but I can not find where the include directive for it is on any of the files from the project.
can someone guide me in the right direction.
Thanks
Luis

cr_startup_lpc11.c is a source file, not an include file. It contains the startup code for the system that is executed as the MCU comes out of reset.

Hi,
so is it used by the linker? I can not see any mention of it on any of the code.
Thanks
Luis

cr_startup_lpc11.c is executed from reset and after setting up the system calls the function 'main' within your application code. There is no need for your application code to call anything within the cr_startup_lpc11.c file.

Ok, so what you are saying is that this file is generated automatically by LPCXpresso and added to the project when I create it?
Best Regards
Luis

Yes, it is created automatically by LPCXpresso IDE - as long you tick "create startup files" when you run through the project wizard.

Hello,

Another question about the startup file - I have noticed there are some differences between the startup file which is automatically generated by the project wizard and the startup file which are used in the example projects. Which one should I use for my projects?

Thanks

Martin

The startup code is periodically tweaked, and sometime is takes a while for pre-existing example projects to be updated with the newer startup code.

When creating a new project, we would recommend that you always use the version of the startup code created by the project wizard.
