sorry for this beginner question: I am new to developping with the STM32 platform.

I just acquired an STM32F103 evaluation board and the Atollic TrueStudio software.


This works perfectly, I could compile and execute the standard "blinking LED" project,

so basically I have no problem with the chain of tools itself.


I see that the provided code uses some system calls such as







On the ST website, they apparently direct you toward "Mbed OS" which is documented

but it seems to be different system calls than the ones used by Atollic TrueStudio, and

the code produced seems to be way more heavy (the blinking LED example compiled with

Mbed CLI is about 50k, where the one compiled with TrueStudio is about 2.5K !).


I tryed to find a reference manual for those calls provided in "TrueStudio", but so far I have

been unlucky. I tryed to type searches such as "reference manual STM32F103" on the ST website,

forum and google, or even some of the system calls like "STM_EVAL_LEDInit" but no luck so far.


Could someone be kind enough to point me in the right direction ?


Thanks !
