Please note that STEVAL-MKI109V3 board is OBSOLETE. Replacement with STEVAL-MKI109D is recommended.

This folder contains a simple STEVAL MKI109V3 CubeMX .ioc project file, which may be used to set up a basic system based on SPI with interrupt and UART capability and that can be used to test SPI-based examples.

Please read the STM32CubeMX documentation to understand how to automatically generate a simple software project that can be selected among several different toolchains, from basic Makefile to more complex ones, like IAR EWARM and Keil MDK-ARM.

Once a simple project has been generated, it needs to be customized in order to be able to run a driver example. Below there is a short description of the steps required to run $STDC_PATH/lsm6dsv16x_STdC/examples/lsm6dsv16x_fifo_irq.c.

1. Open the $STDC_PATH/_prj_MKI109V3/Src/main.c file previously generated to edit it

2. Define the prototypes for both the example routine and its interrupt handler:

/* Private function prototypes -----------------------------------------------*/
/* USER CODE BEGIN PFP */

/* add prototypes */
void lsm6dsv16x_fifo_irq(void);
void lsm6dsv16x_fifo_irq_handler(void);

/* USER CODE END PFP */

3. Call the example routine inside the main loop:

  /* Infinite loop */
  /* USER CODE BEGIN WHILE */
  while (1)
  {
    /* USER CODE END WHILE */

    /* USER CODE BEGIN 3 */

    /* call example main routine */
    lsm6dsv16x_fifo_irq();
  }
  /* USER CODE END 3 */

4. Define the general interrupt callback (which overwrites the default one, since it is declared as __weak) and call the example interrupt handler:

/* Private user code ---------------------------------------------------------*/
/* USER CODE BEGIN 0 */

/* overwrite default interrupt callback */
void HAL_GPIO_EXTI_Callback(uint16_t GPIO_Pin)
{
  lsm6dsv16x_fifo_irq_handler();
}

/* USER CODE END 0 */

1. Add the $STDC_PATH/lsm6dsv16x_STdC/driver/lsm6dsv16x_reg.c driver and $STDC_PATH/lsm6dsv16x_STdC/examples/lsm6dsv_fifo_irq.c example to the project.

2. Add the $STDC_PATH/lsm6dsv16x_STdC/driver directory to the compiler include path, e.g. :

CFLAGS += -I $STDC_PATH/lsm6dsv16x_STdC/driver

3. Add STEVAL_MKI109V3 to the list of preprocessor enabled macros for the compiler, e.g :

CFLAGS += -D STEVAL_MKI109V3

Open a serial port emulator and configure it as 115200 8n1:
