Two Powerful Features for Smarter Sensor Validation (SENT and PSI5)
CANoe Quick Tip
SENT and PSI5 are digital communication protocols used to connect a sensor to an Electronic Control Unit (ECU). CANoe offers advanced features for testing the communication between sensors and ECUs. This article highlights two particularly useful functions: the ability to switch a sensor’s supply voltage on and off, and a method for implementing a user-defined CRC for SENT.
What Can You Do With This Function or Workflow? What Problems Does It Solve?
Flexible SENT CRC Handling
The SetCustomCRCCalculation function lets you easily integrate your own CRC algorithms via CAPL – perfect for testing sensors that use manufacturer-specific CRC variants.
Smart Power Control for Sensors
SwitchSupplyVoltage allows you to dynamically control the power supply of SENT and PSI5 sensors during a measurement, making it simple to analyze reset and start-up characteristics with just a few clicks.
Where Can You Find This Function in CANoe? | How to Start the Process?
Both functions are part of CANoe’s powerful CAPL API and can be easily integrated into simulation and test scripts. Since the Sensor API is based on CANoe’s proven system variable concept, functions or function results can also be accessed directly from analysis windows and Panels.
