Interface description4.3.1.6 canControlInitializeThe function sets the operating mode and bitrate of a CAN connection. Thecomplete syntax of the function is:HRESULT canControlInitialize (HANDLE hControl,UINT8 bMode,UINT8 bBtr0,UINT8 bBtr1 );Parameters:hControl[in] Handle of the opened CAN controller.bMode[in] Operating mode of the CAN controller. For the operating mode, acombination of the following constants can be specified:CAN_OPMODE_STANDARD:Accepts CAN messages with 11-bit identifiers.CAN_OPMODE_EXTENDED:Accepts CAN messages with 29-bit identifiers.CAN_OPMODE_LISTONLY:CAN controller is operated in “List only“ mode.CAN_OPMODE_ERRFRAME:Errors are indicated to the application via special CAN messages.CAN_OPMODE_LOWSPEED:CAN controller uses low speed coupling.bBtr1[in] Value for the bus timing register 0 of the CAN controller. The valuecorresponds to the BTR0 register of the Philips SJA 1000 CAN controllerwith a cycle frequency of 16 MHz.bBtr1[in] Value for the bus timing register 1 of the CAN controller. The valuecorresponds to the BTR1 register of the Philips SJA 1000 CAN controllerwith a cycle frequency of 16 MHz.Return value:If run successfully, the function returns the value VCI_OK, otherwise an errorcode not equal to VCI_OK. Further information on the error code is providedby the function.The function resets the controller hardware internally according to the functionComments:canControlReset and then initializes the controller with the specified parameters.The function can be called from every controller status.54Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
Interface descriptionFurther information on the bus timing values in the parameters bBtr0 andbBtr1 is given in the datasheet of the Philips SJA 1000 CAN controller.The following table shows the bus timing values for all bitrates specified bythe CiA or CANopen.Bitrate (kbit) Pre-defined constants for BTR0, BTR1 BTR0 BTR110 CAN_BT0_10KB, CAN_BT1_10KB 0x31 0x1C20 CAN_BT0_20KB, CAN_BT1_20KB 0x18 0x1C50 CAN_BT0_50KB, CAN_BT1_50KB 0x09 0x1C100 CAN_BT0_100KB, CAN_BT1_100KB 0x04 0x1C125 CAN_BT0_125KB, CAN_BT1_125KB 0x03 0x1C250 CAN_BT0_250KB, CAN_BT1_250KB 0x01 0x1C500 CAN_BT0_500KB, CAN_BT1_500KB 0x00 0x1C800 CAN_BT0_800KB, CAN_BT1_800KB 0x00 0x161000 CAN_BT0_1000KB, CAN_BT1_1000KB 0x00 0x144.3.1.7 canControlResetThe function resets the controller hardware and the set message filters of a CANconnection. The complete syntax of the function is:HRESULT canControlReset ( HANDLE hControl );Parameter:hControl[in] Handle of the opened CAN controller.Return value:If run successfully, the function returns the value VCI_OK, otherwise an errorcode not equal to VCI_OK. Further information on the error code is providedby the function.The function resets the controller hardware, removes the set acceptance filter,deletes the contents of the filter lists and switches the controller “not initialized”.At the same time, the message flow between the controller and themessage channels connected to it is interrupted.Comments:When the function is called, a currently active transmit process of the controlleris aborted. This may lead to transmission errors or to a faulty message telegramon the bus.Further information is given in section 3.1.2.55Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
