Bugfix ppo2 high/low check in OC mode:
The fallback option which is used in CC mode was applied to the OC mode as well. As result the check could be deactivated depending on the fallback state, even if a OC dive is performed. now the check will always be performed if the dive mode is OC.
Added vibration warning:
The internal buzzer of the GPIO_V2 may now be used as additional warning notificator. It can be activated using the check button in the customer view menu. The vibration will be active while the warning message is displayed in the dive window. In case the diver is in the menu then the warning will be active for a shorter duration.

# OSTC4 Code Modules # ## Main CPU - aka CPU1-Discovery ## For historical reasons, the firmware of the main CPU was divided in three parts. It helps development, allow smalled upgrades, and improve security as a bad manipulation won't kill the bootloader, responsible fot the next firmware upgrade. ### Bootloader ## The code responsible to upload new firmwares for both CPU. ### Font Pack ### This module does not contains any code. Just font data and images. ### Firmware code ### The main OSTC4 firmware. The more important modules are: - Buehlmann decompression algorithm. - VPM decompression algorithm. - The simulator and dive planner. - Logbook display (surface and dive mode). - All user interface code, during dive or surface mode (`t*.c` files). - Graphics (gfx) engine. - Plus interface to the other CPU, the management of the _LCD_ screen, and the optional _Bonex_ scooter interface (No longer supported) ## Small CPU - aka CPU2-RTE ## The _Real Time_ CPU handle everything that requires precise timming to function perperly. The most important modules are: - Real time computation of gas exchanges during dive (aka the _LifeData_ structure). - Analog to digital conversion for the ... ambient light sensor. - I2C bus interface to the pressure sensor, the magnetic compass and the battery gauge. - SPI bus interface to the buttons and to the other CPU. - Serial interface to the _RS232-over-Wireless_ connection.
