11. Remove the BOARD_HEADER from the preprocessor defined symbols (the #include

BOARD_HEADER line will be updated by the #include "board.h" line when running the

automatic script on the user application sources files).

12. Add these defines in the preprocessor defined symbols:

•

USE_STDPERIPH_DRIVER: this define is used to enable the StdPeriph drivers.

•

USE_MBxxx_REVx: to define the project target board

•

STM32W108XX: to define the StdPeriph target product

Note:

For boards MB951 and MB950, only one revision exists, so USE_MBxxx_REVx can be

USE_MB950 when using the board MB950 and USE_MB951 when using the board MB951.

Update application sources files

Launch the automatic Perl script on the user application source files that makes all

possible firmware changes (CMSIS support, including types, handler names, core

macro names…). For more details on these changes, please refer to file trace.log.

If the user application uses a specific interrupt, you need to edit manually the interrupt

IRQ handler files:

In stm32w108xx_it.c, call the ISR handler defined by the hal in the IRQ handler defined by

CMSIS (refer to Table 7: STM32W108xx HAL exception names vs. CMSIS).

Example:

/**

* @brief

This function handles PendSVC exception.

* @param

None

* @retval None

void PendSV_Handler(void)

{

halPendSvIsr();

}

In stm32w108xx_it.h, add the ISR handler prototype.

Library configuration section inside file stm32w108xx.h:

In file stm32w108xx.h, select the case that corresponds to the product that you are using:

STM32W108CC, STM32W108CB…

Select whether you want to use the STM32W108xx standard peripheral drivers through

define

USE_STDPERIPH_DRIVER.

Configure values for: HSE (high speed external quartz), HSE startup timeout, HSI (internal

high speed oscillator), LSE (low speed external quartz) and LSI (low speed internal

oscillator)

If you wish to use the assert function, refer to step 5 in Section 3.1.3: Library user and

toolchain specific files
