Public Functions Documentation

function syn_ccp_init

Initialize CCP slave instance.

void syn_ccp_init (
    SYN_CCP_Slave * slave,
    uint16_t station_addr
) 

Parameters:

• slave Pointer to CCP slave handle.
• station_addr 16-bit CCP station address.

function syn_ccp_process_cro

Process incoming Command Receive Object (CRO) frame.

bool syn_ccp_process_cro (
    SYN_CCP_Slave * slave,
    const uint8_t cro,
    uint8_t dto_out
) 

Parameters:

• slave Pointer to CCP slave handle.
• cro 8-byte CRO input CAN payload.
• dto_out 8-byte buffer to receive Command Return Message (DTO/CRM).

Returns:

True if DTO response frame is ready to transmit.

---

function syn_ccp_service_daq

Service periodic DAQ sampling tick.

bool syn_ccp_service_daq (
    SYN_CCP_Slave * slave,
    uint8_t event_channel,
    uint8_t dto_out,
    uint8_t * list_idx,
    uint8_t * odt_idx
) 

Parameters:

• slave Pointer to CCP slave handle.
• event_channel Trigger event channel index.
• dto_out Output buffer for DAQ DTO packet.
• list_idx Output index of transmitting DAQ list.
• odt_idx Output index of transmitting ODT.

Returns:

True if a DAQ packet is ready to send.

---

function syn_ccp_set_mta

Set Memory Transfer Address (MTA0 or MTA1).

void syn_ccp_set_mta (
    SYN_CCP_Slave * slave,
    uint8_t mta_num,
    uint8_t ext,
    uintptr_t addr
) 

Parameters:

• slave Pointer to CCP slave handle.
• mta_num 0 for MTA0, 1 for MTA1.
• ext Address extension.
• addr Target memory address.
