BM_TxTaskTypeDef data structure.
Members
Section titled “Members”| Member | Declaration | Description |
|---|---|---|
type |
uint8_t type |
Type ID of the TX task, see BM_TxTaskTypeTypeDef for details. |
version |
uint8_t version |
Version of BM_TxTaskTypeDef, set to 1 for BMAPI1.x. |
unused |
uint8_t unused [32] |
For backward-compatibility only |
flags |
uint8_t flags |
CAN message control Flags, see BM_MessageFlagsTypeDef for details. |
length |
uint8_t length: 7 |
Length of payload in unit given by ‘lengthunit’ (not DLC) |
lengthunit |
uint8_t lengthunit: 1 |
Unit of length, 0=1B, 1=128B, default as 0, that is, length in bytes Note that not payload buffer might not be 100% used, user would need to check specific data header in payload for further information, i.e. ((BM_CanfdDataTypeDef*)txtask.payload)->ctrl.tx.DLC |
delay |
uint16_t delay |
Delay within tx cycle, that is, offset of tx timing slot within tx cycle (given by ‘cycle’ field) i.e. If cycle=50 and delay=10, this txtask will be executed at 10, 60, 110, 160, etc. |
cycle |
uint16_t cycle |
ms delay between rounds |
nrounds |
uint16_t nrounds |
num of cycles, nrounds=0xFFFFU indicates INFINITE |
nmessages |
uint16_t nmessages |
messages per round, default as 1 message/cycle |
id |
uint32_t id |
Generic ID field, normally you would need to set specific ID structure instead (e.g. CAN.SID). |
SID |
uint32_t SID: 11 |
CAN Standard ID |
EID |
uint32_t EID: 18 |
CAN Extended ID |
SID11 |
uint32_t SID11: 1 |
Reserved |
unimplemented1 |
uint32_t unimplemented1: 2 |
Reserved |
ID |
uint8_t ID |
LIN message id, 0~63 |
CHECKSUM |
uint8_t CHECKSUM |
LIN manual checksum value, only valid if (flags & BM_LIN_MESSAGE_FLAGS_USER_CHECKSUM) != 0 |
startbit |
uint16_t startbit |
Start bit of data increment, currently only 8-bit aligned value is accepted |
nbits |
uint8_t nbits |
Number of bits of data increment, currently only 32 is accepted |
format |
uint8_t format |
0x80=Intel, 0x00=Motorola |
min |
uint32_t min |
Minimum value of the Increment range |
max |
uint32_t max |
Maximum value of the Increment range |
step |
uint32_t step |
Step of the Increment range |
seed |
uint32_t seed |
Random seed |
pattern |
} pattern |
Changing pattern of a Volatile TX task |
e2e |
uint8_t e2e |
Index of E2E (in E2E table), currently unsupported |
e2e_reserved |
uint8_t e2e_reserved [15] |
Reserved for future (e.g. E2E information) |
payload |
uint8_t payload [64] |
Default payload data, note this is also the template payload of the unchanged part in a volatile TX task |
This data-structure reference follows the current BUSMUST BMAPI SDK.
