USE_STM32303C_EVAL
(1)
stm32303C_eval.h
Default status: disabled
This define statement is used to include the
driver for STM32303C_EVAL board, when
used.
VECT_TAB_SRAM
system_stm32f30x.c
Default status: disabled
When enabled, this define statement
relocate the vector table in the Internal
SRAM
VECT_TAB_OFFSET
Default value: 0x00
Defines the vector table base offset. It must
be a multiple of 0x200.
Use this define statement to build an
application that will be loaded at an address
different from the Flash memory base
address (for example, when building an
application to be loaded through in-
application programming (IAP) program).
Notes:
(1)
These define statements are declared in the compiler preprocessor section of the template projects
provided within the library. As a consequence, you do not need to enable them in the corresponding
header file.
2.2 Library programming model
Direct register Access
This model is based on direct register access using the CMSIS layer. This layer provides
the definition of all STM32F30/31xx peripheral registers and bits, as well as memory
mapping.
The advantage of this approach if that the code produced is compact and efficient. The
drawback is that the developer should know in details the peripheral operation, registers
and bits meaning, and the configuration procedure. This task is time consuming, and might
lead to programming errors, which may slow down the project development phase.
To use this model, poceed as follows:
1. Comment the line #define USE_STDPERIPH_DRIVER in stm32f30x.h file. Make sure
that this define statement is not defined in the compiler preprocessor section.
2. Use peripheral registers structure and bits definition available within stm32f30x.h to
build the application
