Added new PreDiveCheck info page: In case a DiveO2 sensor is connected to the OSTC than the values of the DiveO2 internal pressure and temperature sensors may be used for predive checks. The pressure sensors is used for over / under pressure test and the values are visualized using a graph to make it easier to check if the pressure keeps stable. The temperature measurement gives an indication if the scrubber is getting active. This view is highly dependend on the surface temperature but may be useful e.g. for diving in european area. In addition the values ofthe connected sensors are shown.

# How to Create From Scratch a Project for _CPU2-RTE_ Code #

Follow the same procedure than for [CPU1](Detailed CPU1-Discovery Project.md), with changes:

- Create a new _board_ for processor:  
>   Series: `STM32F4`  
>   Mcu: `STM32F411xE`  
>   Debug: `JTAG`  

- Add `Small_CPU` linked source directory (instead of _Discovery_)

- Use linker script `OSTC4/Small_CPU/CPU2-F411.ld`
