Library file structure

Firmware implementation is split between the following files:

●

dspin.c

–

Microcontroller peripherals initialization

–

dSPIN application commands implementation

–

Library support functions implementation

●

dspin.h

–

Function prototypes for implemented commands and support functions

–

Register value (options) definition

–

Register mask definition

–

Macros for selected function parameter conversions

–

Demonstration board related definitions - GPIO signals and peripherals

assignment

●

main.c

–

Example of library usage - system configuration / function calls

●

Other microcontroller configuration files, such as

–

clock.c, -.h, stm32f10x_conf.h (peripherals configuration), stm32f10x_it.c, -.h

(interrupt routines) and standard library for GPIO and SPI

Firmware is available for download in compressed zip format. By decompressing the archive

the following folder structure is created on a drive:

Firmware library folder structure

The “Libraries” folder contains microcontroller related files like peripheral source/header

files, startup file, etc.
