STM8L15x standard firmware library architecture

3.1.1

Description of the STM8L15x standard firmware library

The stm8l15x.h header file contains the definitions of constants and register structures for

all peripherals. Uncomment #define USE_STDPERIPH_DRIVER when using the

STM8L15x standard firmware library. It also includes common types definition used by the

peripheral drivers. In addition, stm8l15x.h must be included in your main() routine.

The stm8l15x_conf.h file of the STM8L15x standard firmware library is used to configure the

library by enabling the peripheral functions that are only used by your application (see

Figure 16).

The peripheral interrupt function file, stm8l15x_it.c, must be modified to include the code to

handle the interrupts used by your application.

Each peripheral driver is made up of the following files:

●

The source code stm8l15x_<periph>.c containing all the software functions required to

use the corresponding peripheral.

●

The header stm8l15x_<periph>.h including the peripheral function prototypes as well

as the variables, constant and structures used within these functions.

The flow that must be followed to create your application software using the STM8L15x

standard firmware library is described in Section 5.3: Creating your own project.
