function syn_lss_master_build_config_bit_timing

Build an LSS Master request frame to configure Bit Timing / Baud rate. 

void syn_lss_master_build_config_bit_timing (
    SYN_CAN_Frame * frame,
    uint8_t baud_table_idx
)

Parameters:

  • frame Output frame buffer.
  • baud_table_idx Baud rate index (SYN_LSS_BAUD_*).

function syn_lss_master_build_config_node_id

Build an LSS Master request frame to configure Node-ID. 

void syn_lss_master_build_config_node_id (
    SYN_CAN_Frame * frame,
    uint8_t new_node_id
)

Parameters:

  • frame Output frame buffer.
  • new_node_id Target Node-ID (1..127).

function syn_lss_master_build_store_config

Build an LSS Master request frame to store configuration to NVM. 

void syn_lss_master_build_store_config (
    SYN_CAN_Frame * frame
)

Parameters:

  • frame Output frame buffer.

function syn_lss_master_build_switch_mode

Build an LSS Master request frame to switch global mode. 

void syn_lss_master_build_switch_mode (
    SYN_CAN_Frame * frame,
    uint8_t mode
)

Parameters:

  • frame Output frame buffer.
  • mode Target LSS mode (SYN_LSS_MODE_OPERATION or SYN_LSS_MODE_CONFIGURATION).

function syn_lss_slave_init

Initialize LSS Slave state instance. 

void syn_lss_slave_init (
    SYN_LSSSlave * slave,
    const SYN_LSSAddress * addr,
    uint8_t initial_node_id
)

Parameters:

  • slave Pointer to slave handle.
  • addr Pointer to LSS unique 128-bit identity address.
  • initial_node_id Starting node-ID (or 0xFF for unconfigured).

function syn_lss_slave_process

Process an incoming CAN frame for LSS Slave processing. 

bool syn_lss_slave_process (
    SYN_LSSSlave * slave,
    const SYN_CAN_Frame * frame,
    SYN_CAN_Frame * resp
)

Parameters:

  • slave Pointer to LSS Slave handle.
  • frame Incoming CAN frame (COB-ID 0x7E5).
  • resp Output CAN frame buffer (populated with 0x7E4 response if required).

Returns:

True if a response frame should be transmitted over CAN.
