[riot-users] using lis3dh in STM32F4 discovery board

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
