Hi,
the driver might actually work with both devices (though I am not 100%
sure). But if I remember correctly, the LIS sensor is connected via SPI
on the discovery board while the driver is using I2C only, Have you
checked this?
Cheers,
Hauke

Hi Alicja,
and welcome to RIOT! If I see it correctly, the a accelerometer that's
mounted on the stm32f4 discovery board is LIS3D*S*H whereas we only
have support for the LIS3DH accelerometer currently. I assume they are
not too different, but it might be the reason why the app does not
work out of the box. Also: did you make sure that the sensor is really
connected to SPI_0 in RIOT?
Best,
Peter

Hi,
I am using RIOT-OS in STM32F4discovery. The hello world program runs
very well. Unfortunately I can *compile* the lis3dh example (located
in /RIOT/tests/driver_lis3dh) but the program didn’t run on the board
correctly. Because I read 255 from the *LIS3DH_REG_WHO_AM_I*
Register. Did you have any idea how to let the lis3dh example run
correctly in STM32F4discovery properly.
Many thanks,
Abdel
Similar to the hello world program, I copied the
/RIOT/tests/driver_lis3dh in a new directory.
I added at the beginning of the main program:
#include <stdio.h>
#include "board.h"
#include "xtimer.h"
#include "periph/spi.h"
#include "periph/gpio.h"
#include "lis3dh.h"
#include "vtimer.h"
#define LIS3DH_CS GPIO_PIN(PORT_E, 3)
#define LIS3DH_SPI SPI_0
#define LIS3DH_INT1 GPIO_PIN(PORT_E, 0)
#define LIS3DH_INT2 GPIO_PIN(PORT_E, 1)
I used the following Makefile:
APPLICATION = driver_lis3dh
#include ../Makefile.tests_common
RIOTBASE ?= $(CURDIR)/../RIOT
QUIET ?= 1
FEATURES_REQUIRED = periph_spi periph_gpio
USEMODULE += lis3dh
USEMODULE += xtimer
USEMODULE += vtimer
include $(RIOTBASE)/Makefile.include
