Structure Elements

Item Description
icscm_uint8 Mode CAN controller mode when the neoVI device goes online or runs a CoreMini script. 

Default value = 0
NORMAL 0
DISABLED 1
LISTEN ONLY 3
LISTEN ALL 7
scm_uint8 SetBaudrate The bit rate of a CAN channel can be selected one of two ways. It can either be selected from a list of common bit rates (SetBaudrate=1) or the user can specify the CAN timing parameters (SetBaudrate=0) 

Default value = 0
AUTO  (Select from bitrate list using Baudrate parameter) 0
USE_TQ (Use time quanta parameters 1


icscm_uint8 Baudrate The bit rate of a CAN channel can be selected from a list of common bit rates Write the correct enumeration for the desired bit rate and ensure that SetBaudrate is 1(auto)

Default value = 8

Note: This parameter is only applicable if SetBaudrate = 1
20000 0
33333 1
50000 2
62500 3
83333 4
100000 5
125000 6
250000 7
500000 8
800000 9
1000000 10
icscm_uint8 NetworkType Currently Not used. Will be supoprted in neoVI Yellow to software select which CAN transceiver to use (DW vs SW vs LSFT).
icscm_uint8 TqSeg1 Phase 1 segment
icscm_uint8 TqSeg2 Phase 2 segment
icscm_uint8 TqProp Propagation delay
icscm_uint8 TqSync Syncro jump width
icscm_uint16 BRP
icscm_uint16 auto_baud Enables the auto bitrate feature. 1 = enable, 0 = disable.

Default value = 0
