@par Example Description
This example shows how to use CRC (cyclic redundancy check) calculation unit to
get a CRC code of a given buffer of data word(32-bit), based on a fixed generator
polynomial(0x4C11DB7).
@par Directory contents
- Examples/CRC/stm32f10x_conf.h Library Configuration file
- Examples/CRC/stm32f10x_it.c Interrupt handlers
- Examples/CRC/stm32f10x_it.h Header for stm32f10x_it.c
- Examples/CRC/main.c Main program
@par Hardware and Software environment
- This example runs on STM32F10x High-Density, STM32F10x Medium-Density and
STM32F10x Low-Density Devices.
- This example has been tested with STMicroelectronics STM3210E-EVAL (STM32F10x
High-Density) and STM3210B-EVAL (STM32F10x Medium-Density) evaluation boards
and can be easily tailored to any other supported device and development
board.
@par How to use it ?
In order to make the program work, you must do the following :
- Create a project and setup all project configuration
- Add the required Library files :
- stm32f10x_rcc.c
- stm32f10x_crc.c
- system_stm32f10x.c
- Edit stm32f10x.h file to select the device you are working on.
@b Tip: You can tailor the provided project template to run this example, for
more details please refer to "stm32f10x_stdperiph_lib_um.chm" user
manual; select "Peripheral Examples" then follow the instructions
provided in "How to proceed" section.
- Link all compiled files and load your image into target memory
- Run the example
@note
- Low-density devices are STM32F101xx and STM32F103xx microcontrollers where
the Flash memory density ranges between 16 and 32 Kbytes.
- Medium-density devices are STM32F101xx and STM32F103xx microcontrollers where
the Flash memory density ranges between 32 and 128 Kbytes.
- High-density devices are STM32F101xx and STM32F103xx microcontrollers where
the Flash memory density ranges between 256 and 512 Kbytes.
