Interface descriptionReturn 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 vciFormatError.Comments:Further information on the data provided by the function is given in the descriptionof the data structure CANLINESTATUS in section 5.2.2.4.3.1.5 canControlDetectBitrateThis function determines the current bitrate of the bus to which the CAN connectionis connected. The complete syntax of the function is:HRESULT canControlDetectBitrate (HANDLE hControl,UINT16 wTimeoutMs,UINT32 dwCount,PUINT8 pabBtr0,PUINT8 pabBtr1,PINT32 plIndex );hControl[in] Handle of the opened CAN controller.Parameters:wTimeoutMs[in] Maximum waiting time in milliseconds between two messages on thebus.dwCount[in] Number of elements in the bit timing tables pabBtr0 or pabBtr1.pabBtr0[in] Pointer to a table with the values to be tested for the bus timing register0. The value of an entry corresponds to the BT0 register of the Philips SJA1000 CAN controller with a cycle frequency of 16 MHz. The table mustcontain at least dwCount elements.pabBtr1[in] Pointer to a table with the values to be tested for the bus timing register1. The value of an entry corresponds to the BT1 register of the Philips SJA1000 CAN controller with a cycle frequency of 16 MHz. The table mustcontain at least dwCount elements.plIndex[out] Pointer to a variable of type INT32. If run successfully, the functionreturns the table index of the found bit timing values in this variable.52Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
Interface descriptionReturn 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.Further information on the bus timing values in the tables pabBtr0 andpabBtr1 is given in the datasheet of the Philips SJA 1000 CAN controller.Comments:To detect the bitrate, the CAN controller is operated in “List only” mode. It istherefore necessary for two further bus nodes to transmit messages when thefunction is called. If no messages are transmitted within the time specified inwTimeoutMs, the function returns the value VCI_E_TIMEOUT.If run successfully, the function receives the variables to which the parameterplIndex shows the index (including 0) of the found values in the bus timingtables. The corresponding table values can then be used to initialize the CANcontroller with thee function canControlInitialize.The function can be called in the undefined and stopped status. Further informationon this is given in section 3.1.2.1.53Copyright IXXAT Automation GmbH C-API Programming Manual, Version 1.5
