Automated Tester

Confidential

Environment: Microcontroller: Power PC 555

• Tools: CAN, CANalyzer.
• HW: CANcard XI.
• SW: Visual Studio, Analyzer, Slick Edit.

Project Overview:

The tester involved controlling and testing I/O ports, a USB controlled stepper motor to achieve to and fro motion of the vehicle body. It involved interfacing CAN using a Vector CANCard XI. A variable power supply to feed different types of inputs was also interfaced. From the software point, device drivers for all I/O controls were supplied by NI. A CAN database is used to convert raw data. This database has become a de facto standard in the motor vehicle industry. Visual Studio framework was used to interface these device drivers and rewrite all the functional test cases so that testing could be automated.

Responsibilities:

• Acceptance test plan development and execution.
• Debugged and Tested software modules.
• I/O testing of CANbus modules by configuring it using Canmenu GUI.
• Designing the project and interfacing CAN use a Vector CANCard XI.
• Involved in crafting with relays to simulate active and passive fields.
• Tested the project on VxWorks RTOS and verified the C code for standards.
• Multiparameter Sensing and Digital Control
