Templates_LL 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:
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 AN : STM32Cube firmware examples for stm32c0xx Series
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 stm32c0xx_it.h
- Replace file stm32c0xx_it.c
