Library Structure
Description: Each subdirectory contains a ‘C’ sub folder which contains peripheral library files.
4.3.2.1 C directory
Location:
Description: Each subdirectory contains the source files, header files and an example folder
showing the usage of the functions.
Files: Periph.c, Periph.h, Periph_hr.h
Periph.c
Inclusion of periph_hr.h, periph.h, ST7lib_config.h. It contains the Peripheral functions with
some conditional compilation options.
Periph.h:
This contains the (typedef enum) parameters for each peripheral, prototypes of functions de-
fined in Peripheral.c and definition of Peripheral constant definitions.
Periph_hr.h
This file contains the bit mapping of the hardware registers used for the peripherals.
4.4 DEVICES
Location:
Description:
Notes:
1. This software covers 13 main devices and their subsets. You have to include the file from
the main device section in order to support the related subsets.
2. The register files in the ST7 library are different from those provided with the STVD7 ver 3.x.
Take care to include the correct one.
