How to use and customize the library
The previous initialization step can be merged in one single line to optimize the
code size:
PPP_InitTypeDef PPP_InitStructure = { val1, val2,.., valN}
b. Configure only a few members of the structure: in this case modify the
PPP_InitStructure variable that has been already filled by a call to the
PPP_StructInit(..) function. This ensures that the other members of the
PPP_InitStructure variable are initialized to the appropriate values (in most cases
their default values).
PPP_StructInit(&PPP_InitStructure);
PPP_InitStructure.memberX = valX;
PPP_InitStructure.memberY = valY;
/*where X and Y are the members the user wants to
configure*/
3. Initialize the PPP peripheral by calling the PPP_Init(..) function.
PPP_Init(PPP, &PPP_InitStructure);
4. At this stage the PPP peripheral is initialized and can be enabled by making a call to
PPP_Cmd(..) function.
PPP_Cmd(PPP, ENABLE);
The PPP peripheral can then be used through a set of dedicated functions. These
functions are specific to the peripheral. For more details refer to the peripheral driver
chapter.
PPP_DeInit(..) function can be used to set all PPP peripheral registers to their default
values (only for debug purpose):
PPP_DeInit(PPP);
To modify the peripheral settings after configuring it, you have to proceed as follows:
PPP_InitStucture.memberX = valX;
PPP_InitStructure.memberY = valY;
PPP_Init(PPP, &PPP_InitStructure);
/* where X and Y are the only members that user wants to modify*/
2.4 How to run your first example
The library provides a rich set of examples covering the main features of each peripheral.
All the examples are independent from the development tools. These examples run on
STMicroelectronics STM32303C-EVAL evaluation board and can be easily tailored to any
other supported device and development board. Only source files are provided for each
example and user can tailor the provided project template to run the selected example with
his preferred development Tool.
2.4.1 Prerequisites
1. Latest release of documents and library.
You can download the latest version of STM32F30/31xx related documents and library
from STMicroelectronics web site: www.st.com/stm32 󳘪
2. Hardware: to run the examples, you need an STM32303C-EVAL evaluation board
from STMicroelectronics or any other compatible hardware. 󳘪
3. To use your own hardware, simply adapt the example hardware configuration to your
platform.
4. Development tools󳘪
Use your preferred development tool, MDK-ARM (Keil), EWARM (IAR), RIDE
