@par Example Description
|
|
|
|
This projects provides a reference template through the LL API that can be used to build any firmware application.
|
|
|
|
This project LL template provides:
|
|
- Inclusion of all LL drivers (include files in "main.h" and LL sources files in IDE environment, with option "USE_FULL_LL_DRIVER" in IDE environment)
|
|
Note: If optimization is needed afterwards, user can perform a cleanup by removing unused drivers.
|
|
- Definition of LEDs and user button (file: main.h)
|
|
Note: User button name printed on board may differ from naming "user button" in code: "key button", ...
|
|
- Clock configuration (file: main.c)
|
|
|
|
This project LL template does not provide:
|
|
- Functions to initialize and control LED and user button
|
|
- Functions to manage IRQ handler of user button
|
|
|
|
To port a LL example to the targeted board:
|
|
1. Select the LL example to port.
|
|
To find the board on which LL examples are deployed, refer to LL examples list in "STM32CubeProjectsList.html", table section "Examples_LL"
|
|
or AN4739: STM32Cube firmware examples for STM32F4 Series
|
|
|
|
2. Replace source files of the LL template by the ones of the LL example, except code specific to board.
|
|
Note: Code specific to board is specified between tags:
|
|
/* ============== BOARD SPECIFIC CONFIGURATION CODE BEGIN ============== */
|
|
/* ============== BOARD SPECIFIC CONFIGURATION CODE END ============== */
|
|
|
|
- Replace file main.h, with updates:
|
|
- Keep LED and user button definition of the LL template under tags
|
|
|
|
- Replace file main.c, with updates:
|
|
- Keep clock configuration of the LL template: function "SystemClock_Config()"
|
|
- Depending of LED availability, replace LEDx_PIN by another LEDx (number) available in file main.h
|
|
|
|
- Replace file stm32f4xx_it.h
|
|
- Replace file stm32f4xx_it.c
|

@par Hardware and Software environment
|
|
|
|
- This template runs on STM32F429xx devices.
|
|
|
|
- This template has been tested with NUCLEO-F429ZI RevB board 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 :
|
|
- Open your preferred toolchain
|
|
- Rebuild all files and load your image into target memory
|
|
- Run the example
