linGetMeasBaudrate

Valid for: CANoe DE

​
Function Syntax

float linGetMeasBaudrate();

​
Description

With this function, it is possible to retrieve results of a last baudrate measurement, which is done by calling linMeasHeaderBaudrate() or linMeasRespBaudrate() functions.

​
Parameters

—

​
Return Values

Returns the last measured baudrate [in bit/sec] or -1 on failure.

​
Example

Example 1
Test case for measuring baudrate using LIN header event. These test cases can only be used in the context of test module nodes. 
testcase tcMeasureHeaderBaudrate ()
{
    long waitResult, measBaudrate;
    // set request to measure baudrate according to Synch field of a LIN header
    linMeasHeaderBaudrate(0);
    // wait maximum 1000 [ms] for LIN header with identifier 0x33
    waitResult = TestWaitForLinHeader(0x33, 1000);
    // declare failure if Wait has resumed not due to expected event
    if (1 != waitResult)
    {
        TestStepFail("Test 1.1","No LIN header with ID=0x33 occurred during 1000 ms!");
    }
    // retrieve measured baudrate
    measBaudrate = linGetMeasBaudrate();
    if (-1 == measBaudrate)
    {
        TestStepFail("Test 1.1", "Failed to measure header baudrate!");
    }
    TestStepPass("Test 1.1", "Header baudrate measurement done...");
}
Example 2
Test case for measuring baudrate using certain data byte of a LIN frame. These test cases can only be used in the context of test module nodes. 
testcase tcMeasureDatabyteBaudrate (int byteIndex)
{
    long waitResult, measBaudrate;
    // set request to measure baudrate using the specified byte of a frame with ID=0x33
    linMeasRespBaudrate(0x33, byteIndex);
    // wait maximum 1000 [ms] for a frame with ID=0x33
    waitResult = TestWaitForMessage(0x33, 1000);
    // declare failure if Wait has resumed not due to expected event
    if (1 != waitResult) {
        TestStepFail("Test 1.1","Expected frame has not occurred during 1000 ms!");
    }
    // retrieve measured baudrate
    measBaudrate = linGetMeasBaudrate();
    if (-1 == measBaudrate)
    {
        TestStepFail("Test 1.1", "Failed to measure response baudrate!");
    }
    TestStepPass("Test 1.1", "Response baudrate measurement done...");
}
