linSetRespBitStream

Valid for: CANoe DE

Function Syntax

long linSetRespBitStream (long frameId, byte bitStream[], long numberOfBits); // form 1
long linSetRespBitStream (long frameId, byte bitStream[], long numberOfBits, long timeoutPrevention); // form 2
long linSetRespBitStream (long frameId, byte bitStream[], long numberOfBits, long timeoutPrevention, long count); // form 3

Description

Sets up a bitstream as the response to the specified frame.

Parameters

frameId: LIN frame identifier in the range 0 .. 63
bitStream: The bitstream array to be sent as a response. Maximum number of bits: 2^31-1.
numberOfBits: Number of bits in the bitStream array to be sent.
timeoutPrevention:
- 0: deactivates the timeout prevention for the 7259-transceiver.
- 1: activates the timeout prevention for the 7259-transceiver.
count: Number of times, the bitstream shall be sent as a response before deactivating itself.

Return Values

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

Example

Send LIN response for the frame MotorControl as a bitstream.

// The response consists of 8 data bytes and checksum 
// byte. There are no interbyte spaces.
// Response: [D0=0x1, D1=0x2, D2=0x4, D3=0x8, D4=0x10, D5=0x20, D6=0x40, D7=0x80, CS=0x52]
