Project I:

Software implementation in C/C++ for testing the functionality of a device. A test box with two circuit boards was created for the test. Each circuit board contains a microcontroller (Stellaris LM3s9b81 and LM3s9b96) that communicates with the DUT via CAN. Two microcontrollers (iMx6 and SPC560b54) are mounted on the DUT.

The following functionalities were tested:

• Wake-up of the DUT via CAN message and external wake-up.
• Image and video processing.
• GPS communication.
• Overcurrent detection.
• CAN communication between the four CAN interfaces on the DUT and the CAN interfaces in the test box, as well as UART communication.
• Audio processing.
