Description of the STM8S standard firmware library
The stm8s.h header file contains the definitions of constants and register structures for all
peripherals. Uncomment #define USE_STDPERIPH_DRIVER when using the STM8S
standard firmware library.
In addition, stm8s.h must be included in your main() routine.
The stm8s_conf.h file of the STM8S standard firmware library is used to configure the
library by enabling the peripheral functions that are only used by your application (see
Figure
supported devices. For example:
#if defined(STM8S208) || defined(STM8S207) || defined(STM8S105)
#define _TIM3 (1)
#endif
In stm8s_conf.h, the HSE value define statement may be adjusted to the oscillator
frequency or to the external clock generator frequency. It is also conditioned by supported
devices. Make sure you have the correct value for the STM8S-DISCOVERY external
oscillator (expressed in Hz). For example:
#define HSE_VALUE ((u32)16000000)
The peripheral interrupt function file, stm8s_it.c, must be modified to include the code to
handle the interrupts used by your application. The stm8s_type.h file includes common
12). In stm8s_conf.h, some peripheral define statements are conditioned by
