You can use the default timeout callback implementation by uncommenting the

define USE_DEFAULT_TIMEOUT_CALLBACK in stm32f4_discovery_lis302dl.h file.

Typically the user implementation of this callback should reset MEMS peripheral

and re-initialize communication or in worst case reset all the application. */
