arm compiler includes documentation

A typical CCS project for TMS570HDK/RM48HDK includes a lot of "standard" header from TI /on my system /ti/ccsv5/tools/compiler/arm_5.0.4/include). In that headers there are a lot of potentially useful stuff like threads, standard algorithms, std:lib objects, stdio, ecc. but for a lot of them I can hardly imagine the effects on a typical microcontroller application (for example: what's the effect of a printf? what file operation are meant for? ...). Perhaps I'm missing something...

Do this headers refers to a ever-linked "std" library?

Where can I found documentation about?

Thank you

Hi Matteo,

I've referred this to one of our subject matter experts who will get back to you.

Matteo,

Look at chapter 7 of the Compiler manual:

http://www.ti.com/general/docs/lit/getliterature.tsp?baseLiteratureNumber=spnu151&fileType=pdf

This chapter will tell you about the compiler runtime library.

To briefly answer your questions:

- Yes this is one big library but it is an archive of many individual objects and only the functions that you need will get linked into your executable. So if you don't *use* printf() your executable might be a lot smaller...

- IO functions like file operations and printf are supported. You could write your own device driver code and target these at some device in your system or you can use the default host driver. The host driver is breakpoint driven (search the doc for C$$IO$$). The implementation is also specific to and depends on having CCS connected.
