Updated menu structure to support new sensor information page: The sensor information page has been added to the sensor submenu of the hardware menu. It will be shown dynamically in case a smart sensor is detected. In order to have this dynamic visualization some new functions had to be added to the general menu file. The information page returns to the sensor menu, for this behavior also a new function had to be added.

User program conditions
The user application to be loaded into the Flash memory using IAP should be built with
these configuration settings:
1. Set the program load address at 0x08003000, using your toolchain linker file
2. Relocate the vector table at address 0x08003000, using the
"NVIC_SetVectorTable"function or the VECT_TAB_OFFSET definition inside the
"system_stm32f10x.c"

can be found here system_stm32f4xx.c
