@par Example Description
This example shows how to use CortexM3 Bit-Band access to perform atomic
read-modify-write and read operations on a variable in SRAM.
@par Directory contents
- CortexM3/BitBand/stm32f10x_conf.h Library Configuration file
- CortexM3/BitBand/stm32f10x_it.c Interrupt handlers
- CortexM3/BitBand/stm32f10x_it.h Header for stm32f10x_it.c
- CortexM3/BitBand/main.c Main program
- CortexM3/BitBand/system_stm32f10x.c STM32F10x system source file
@par Hardware and Software environment
- This example runs on STM32F10x Connectivity line, High-Density, Medium-Density,
XL-Density, High-Density Value line, Medium-Density Value line, Low-Density
and Low-Density Value line Devices.
- This example has been tested with STMicroelectronics STM32100E-EVAL (High-Density
Value line), STM32100B-EVAL (Medium-Density Value line), STM3210C-EVAL
(Connectivity line), STM3210E-EVAL (High-Density and XL-Density) and STM3210B-EVAL
(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 :
- Copy all source files from this example folder to the template folder under
Project\STM32F10x_StdPeriph_Template
- Open your preferred toolchain
- Rebuild all files and load your image into target memory
- Run the example
@note
- Low-density Value line devices are STM32F100xx microcontrollers where the
Flash memory density ranges between 16 and 32 Kbytes.
- Low-density devices are STM32F101xx, STM32F102xx and STM32F103xx
microcontrollers where the Flash memory density ranges between 16 and 32 Kbytes.
- Medium-density Value line devices are STM32F100xx microcontrollers where
the Flash memory density ranges between *** and 128 Kbytes.
- Medium-density devices are STM32F101xx, STM32F102xx and STM32F103xx
microcontrollers where the Flash memory density ranges between *** and 128 Kbytes.
- High-density Value line devices are STM32F100xx microcontrollers where
the Flash memory density ranges between 256 and 512 Kbytes.
- High-density devices are STM32F101xx and STM32F103xx microcontrollers where
the Flash memory density ranges between 256 and 512 Kbytes.
- XL-density devices are STM32F101xx and STM32F103xx microcontrollers where
the Flash memory density ranges between 512 and 1024 Kbytes.
- Connectivity line devices are STM32F105xx and STM32F107xx microcontrollers.
