linSetInterByteSpace

Valid for: CANoe DE

Function Syntax

dword linSetInterByteSpace (long frameID, long index, dword sixteenthBits);

Description

With this function it is possible to set an inter-byte space for a specified frame and a specified byte field. The byte field may belong to the frame header as well as to the frame response.

Inter-byte space is the period between the end of the stop bit of the preceding byte and the start bit of the following byte.

By default, the inter-byte space is 0.

Parameters

• frameID: LIN frame identifier whose inter-byte space should be changed.
  Value range: 0…63

• index: Index of the byte field, before which the inter-byte space should be inserted.
  Value range: 0..N+1, where N=frame length
  0: Inter-byte is inserted between the Synch byte and the Identifier byte.
  1: Inter-byte is inserted before the first data byte.
  N+1: Inter-byte is inserted before the Checksum byte.

• sixteenthBits: Length of the inter-byte space to set [in units of 1/16th of bit time].
  Value range: 0..65535. This corresponds to 0..4095.93 bit times.
  For a LIN standard compliance: The maximum space between the bytes cannot exceed 40% duration compared to nominal transmission time.

Return Values

On success, a value unequal to zero, otherwise zero.

Example

on key 's'
{
    if ( linSetInterByteSpace(0x33, 9, 32) != 0)
    {
        // from now on for frame ID=0x33 the inter-byte space
        // between last data byte field and Checksum byte is 2 bit times
        ...
    }
}
