Detailed Description

The CANpie test functions are used to verify the driver functionality on the CAN controller.

The following tests need to be defined:

• remote frame reception / transmission
• test for autobaud detection
• test for error detection

Include dependency graph for cp_test.h:

Enumeration Type Documentation

enum CP_TEST_CASE

Defines test cases.

The values of the enumeration CP_TEST_CASE are used to start and identify a specific test funtion.

Enumerator:

CP_TEST_BUFFER_TRM_HDI	Test case #1: check hardware description
CP_TEST_BUFFER_TRM_ALL	Test case #2: send on multiple buffers
CP_TEST_BUFFER_TRM_EXT	Test case #3: send Extended Frames
CP_TEST_BUFFER_MIRROR_STD	Test case #4: mirror Standard Frames
CP_TEST_BUFFER_MIRROR_EXT	Test case #5: mirror Extended Frames
CP_TEST_BUFFER_COUNT_STD	Test case #6: count Standard Frames

Function Documentation

void CpTest_01

(

_TsCpPort *

ptsPortV

)

Test number of message buffers.

Parameters:

ptsPortV

Pointer to CAN port structure

The function evaluates the total number of available message buffers and reports the result via a CAN message. The identifier is defined by CP_TEST_TRM_ID_STD.

void CpTest_02

(

_TsCpPort *

ptsPortV

)

Test CAN 2.0A message transmission on multiple buffers.

Parameters:

ptsPortV

Pointer to CAN port structure

The function sends CAN 2.0A messages on all available message buffers. The first message buffer uses the identifier CP_TEST_TRM_ID_STD, for the following an offset of 1 is added.

void CpTest_03

(

_TsCpPort *

ptsPortV

)

Test CAN 2.0B message transmission on multiple buffers.

Parameters:

ptsPortV

Pointer to CAN port structure

The function sends CAN 2.0B messages on all available message buffers. The first message buffer uses the identifier CP_TEST_TRM_ID_EXT, for the following an offset of 1 is added.

void CpTest_04

(

_TsCpPort *

ptsPortV

)

Test CAN 2.0A message reception.

Parameters:

ptsPortV

Pointer to CAN port structure

The function receives a CAN 2.0A message on the identifier defined by CP_TEST_RCV_ID_STD and mirrors the incoming data on the transmit message with the identifier CP_TEST_TRM_ID_STD.

void CpTest_05

(

_TsCpPort *

ptsPortV

)

Test CAN 2.0B message reception.

Parameters:

ptsPortV

Pointer to CAN port structure

The function receives a CAN 2.0B message on the identifier defined by CP_TEST_RCV_ID_EXT and mirrors the incoming data on the transmit message with the identifier CP_TEST_TRM_ID_EXT.

void CpTest_06

(

_TsCpPort *

ptsPortV

)

Test CAN 2.0A message reception on multiple buffers.

Parameters:

ptsPortV

Pointer to CAN port structure

The function receives CAN 2.0A messages on multiple identifiers. The total number of received messages is counted and reported.

void CpTestFail	(	_U08	ubTestCaseV,
		_TvCpStatus	tvStatusV
	)

Report test failure.

void CpTestSuccess

(

_U08

ubTestCaseV

)

Report test success.
