If watchdog fault is detected, the following steps to be performed  Perform uC reset  Set error flag  Remain in fail safe state If DI2 and DI5 is implemented as switched to GND, BSW shall be able to detect short to battery error condition in the respective input pins. BSW shall be able to control and detect the status of DO2 output pin. When DI2/DI5 input pin is not active for at least 200mSec in normal operation state, Display controller shall send 00(OFF) as the value for the corresponding input via vehicle CAN. When DI2/DI5 input pin is active for at least 200mSec in normal operation state, Display controller shall send 01(ON) as the value for the corresponding input via vehicle CAN. If short to Battery error is detected in DI2/DI5 input, the corresponding CAN parameter value shall be transmitted as 10(Error) via vehicle CAN. If Display controller is in under voltage or over voltage state, the CAN parameter value of DI2 and DI5 shall be transmitted as 10(Error) via vehicle CAN. If DO2 CAN parameter value is 00, DO2 output shall be disabled(inactive). If DO2 CAN parameter value is 01, DO2 output shall be enabled(active). If DO2 CAN parameter value is 11, DO2 output shall be retained as last value. If Vehicle CAN bus communication is not available, the last state shall be retained. If DO2 CAN parameter value is 10, DO2 output shall flash at the rate of 1 Hz. When Display controller is in Under voltage, Over voltage state or fail safe state, DO2 output shall be disabled(inactive) despite the value received via CAN. Display controller shall transmit the status(01-ON, 00-OFF) of DO2 output via CAN based on output sensing. If DO2 output error is detected, DO2 status shall be transmitted as 10 via vehicle CAN.

Qt 5 offers a scripting language with JavaScript syntax. By this, HMI development can be performed clean and efficiently as design and logic of the application can be controlled at one place. For optimized performance Qt 5 is using OpenGL. So, the underlying HW acceleration is used. The feature set of the reference application is covering the main functionality of the MultiViu Media middleware for demonstration purposes. 4.3 SW deliverables MultiViu Media will be delivered with:  Leap base SW and multimedia middleware as object libraries configured and integrated for the project hardware  QML based reference application in source code  Target compiler  Tool to configure the CAN database. Note: the build environment is Linux. Qt Creator is open source and can be used on Linux/Windows/Mac.
