Public Functions Documentation¶

function syn_cia401_check_analog_delta¶

Check if any analog input has exceeded its delta threshold for event-driven TPDO.

bool syn_cia401_check_analog_delta (
    SYN_CiA401_Device * dev,
    uint8_t * channel
)

Parameters:

dev Pointer to CiA 401 device instance.
channel Output channel index (0..analog_in_count-1) that changed.

Returns:

True if a change occurred exceeding delta.

function syn_cia401_init¶

Initialize a CiA 401 device state instance.

void syn_cia401_init (
    SYN_CiA401_Device * dev,
    uint8_t dig_in_bytes,
    uint8_t dig_out_bytes,
    uint8_t analog_in_ch,
    uint8_t analog_out_ch
)

Parameters:

dev Pointer to CiA 401 device handle.
dig_in_bytes Number of 8-bit digital input blocks (1..4).
dig_out_bytes Number of 8-bit digital output blocks (1..4).
analog_in_ch Number of 16-bit analog input channels (1..8).
analog_out_ch Number of 16-bit analog output channels (1..8).

function syn_cia401_populate_od¶

Populate a standard CANopen Object Dictionary array with CiA 401 entries.

size_t syn_cia401_populate_od (
    SYN_CiA401_Device * dev,
    SYN_CANOpenODEntry * od_table,
    size_t max_entries
)

Parameters:

dev Pointer to initialized CiA 401 device instance.
od_table Output array of SYN_CANOpenODEntry elements.
max_entries Capacity of od_table array.

Returns:

Number of OD entries populated.
