CAN
CAN module clock (in MHz)
Displays the CAN module clock in MHz.
Settings
Default:
54
Prescalar (for time quantum)
The value by which the oscillator frequency is divided for generating the bit time quanta. The bit time is built up from a multiple of this quanta.
Settings
Default:
6
Time quantum in ns (Tq=Prescalar*1000/CAN module clock)
Time quantum in nano second. Time quantum is calculated based on parameters and formula (Tq=Prescalar*1000/CAN module clock).
Settings
Default:
111.111
Bit segment 1 time quanta (BS1)
Bit segment time quanta before sample point. Valid values are 1 to 16.
Settings
Default:
6
Bit segment 2 time quanta (BS2)
Bit segment time quanta after sample point. Valid values are 1 to 8.
Settings
Default:
3
Baudrate in bits/s (1e9/((BS1+BS2+1)*Tq))
Baudrate for CAN bus calculated based on data parameters and formula (1e9/((BS1+BS2+1)*Tq)).
Settings
Default:
900000
Re-synchronization jump width
Set the synchronization jump width, which determines how many units of Tq a bit can be shortened or lengthened when resynchronizing. Where, Tq=Baud Rate Prescaler/CAN_CLK. Valid values are 1 to 4.
Settings
Default:
1
Receive pin
Select the receiving pin of CAN.
Settings
Default:
PB_8
Transmit pin
Select the transmitting pin of CAN.
Settings
Default:
PB_9
Test Mode
Normal - Does not send any acknowledge message back.
Loopback - Transmission remains possible. CAN reception is ignored.
Silent - Reception remains possible. CAN transmission is held recessive.
Silent loopback - Allows host self-test. Node is disconnected from CAN bus.
Settings
Default:
Normal
Silent, Loopback, Silent loopback
Accept all messages (in FIFO 0)
Enable this parameter to allow all CAN messages in FIFO 0. If it is disabled, then you can select and allow only the required CAN messages.
Settings
Default:
on
off
Filter bank number
Select the filter bank number. Values range between 0 to 13.
Settings
Default:
0
0 to 13
Enable filter bank #
Select enable filter bank parameter to configure the filter bank scale, filter bank mode and FIFO assignment parameters.
Settings
Default:
off
on
Filter bank # scale
Select Single 32-bit
or Dual
16-bit
as filter bank scale.
Settings
Default:
Single 32-bit
Dual 16-bit
Filter bank # mode
Select Identifier mask
or Identifier
list
as filter bank mode.
Identifier mask - In mask mode the identifier registers are associated with mask registers specifying which bits of the identifier are handled.
Identifier list - In identifier list mode, the mask registers are used as identifier registers.
Settings
Default:
Identifier mask
Identifier list
Filter bank # FIFO assignment
Select FIFO 0
or FIFO 1
as
filter bank assignment.
Settings
Default:
FIFO 0
FIFO 1
Filter bank # Id type
Select Standard 11-bit
or Extended
29-bit
as filter bank Id type.
Settings
Default:
Standard 11-bit
Extended 29-bit
Id #
Specify the identifier list value based on the selection of filter bank scale and filter bank mode.
Settings
Default:
0
Mask #
Specify the identifier mask value based on the selection of filter bank scale and filter bank mode.
Settings
Default:
0
