Device-firmware transmit tasks. CAN tasks are hardware-timed periodic or pattern generators. A LIN task on a slave channel is a fixed, header-triggered response, not a periodic transmission. Persistent LIN response tasks require daemon mode.

|---|---|---|
--channel |
(required) | Channel (SN/port, UID/port, legacy index, or name) |
--message / --id |
(required) | CAN ID or LIN response ID 0x00..0x3F |
--cycle |
CAN required; LIN 0 |
CAN interval in ms; LIN responses are header-triggered |
--delay |
0 |
Delay offset within cycle in ms |
--data |
8 zero bytes | Payload hex bytes |
--type |
fixed |
CAN patterns; LIN requires fixed |
--flags |
none | CAN frame flags |
--checksum |
auto |
LIN response checksum model |
--rounds |
infinite |
Number of cycles. 0xFFFF or omit = infinite |
--inc-startbit |
0 |
Start bit for incdata/random |
--inc-nbits |
32 |
Bit width |
--inc-step |
1 |
Increment step |
--inc-min |
0 |
Minimum value |
--inc-max |
max | Maximum value |
Open every master and slave endpoint before installing a finite-round LIN response task. Reconfiguring another channel on the same analyzer can consume or reset a task that was armed too early.
