ChkStart_LINWakeupReqLengthViolation

Valid for: CANoe DE • CANoe4SW DE

​
Function Syntax

  • dword ChkStart_LINWakeupReqLengthViolation (duration MinLength, duration MaxLength);
  • dword ChkStart_LINWakeupReqLengthViolation (duration MinLength, duration MaxLength, char[] CaplCallback);

​
Constructor

TestCheck::StartLINWakeupReqLengthViolation (duration MinLength, duration MaxLength)
  • TestCheck::StartLINWakeupReqLengthViolation (duration MinLength, duration MaxLength);
  • TestCheck::StartLINWakeupReqLengthViolation (duration MinLength, duration MaxLength, char[] CaplCallback);

​
Description

Checks the length of LIN wake-up request. An event will be generated if a measured length of the wake-up request is out of the specified range. Note: According to the LIN specification, the wake-up request is a dominant signal in the range of a minimum of 250µs and a maximum of 5ms. Note: Dependent on the used parameter type, the appropriate bus context in a multibus environment has only to be set before the function is called if the corresponding database object will be ambiguous. Further information on site MultiBus Environment.

​
Parameters

  • MinLength
    • 0: Minimum length shall not be checked
    • \>0: Minimum allowed length
    • Unit: Can be set with ChkConfig_SetPrecision.
  • MaxLength
    • 0: Maximum length shall not be checked
    • \>0: Maximum allowed length time
    • Unit: Can be set with ChkConfig_SetPrecision.
  • CaplCallback: Name of CAPL callback function to be called on generated event. In simulation nodes, this parameter has to be set. In test modules, this parameter is optional.

​
Return Values

  • 0: Check could not be created and must not be referenced
  • > 0: Check was created successfully and may be referenced using the returned (handle-) value.

​
Possible Errors

  • Range specified for wake-up request length is invalid
  • CAPL callback does not exist

Check-specific Queries

Example

...
dword checkId;
ChkConfig_SetPrecision(6); // switch to µs precision
// Create and start the check for LIN wake-up request
checkId = ChkStart_LINWakeupReqLengthViolation(250, 1000, "LINWakeupLenCallback");
ChkConfig_SetPrecision(3); // switch to ms precision (default)
...
// CAPL callback for violation notification
void LINWakeupLenCallback (dword aCheckId)
{
   ChkQuery_EventStatusToWrite(aCheckId);
