DLN_ADC_CONDITION_MET_EV Structure

The DLN_ADC_CONDITION_MET_EV structure is used to store descriptions of ADC events.

DLN_ADC_CONDITION_MET_EV Structure

 typedef struct
 {
    DLN_MSG_HEADER header;
    uint16_t eventCount;
    uint8_t port;
    uint8_t channel;
    uint16_t value;
    uint8_t eventType;
 } __PACKED_ATTR DLN_ADC_CONDITION_MET_EV;

Members:

header

Defines the DLN message header DLN_MSG_HEADER. This structure's header contains the following fields:

Field	Description
size	The size of the message. Must be equal to the size of the DLN_ADC_CONDITION_MET_EV structure.
msgId	Identifies the message. For the DLN_ADC_CONDITION_MET_EV structure it must be set to 0x0610. You can use the DLN_MSG_ID_ADC_CONDITION_MET_EV constant.
echoCounter	Can be used to link a structure to a response. The response will have the same echoCounter value. This field can be any numerical value from 0 to 0xFFFF (65536).
handle	A handle to the DLN-series adapter.

eventCount

Contains the number of generated events after configuration setting.

port

Contains the number of the ADC port.

channel

Contains the number of the ADC channel.

value

Contains the voltage level on the corresponding ADC channel.

eventType

Contains the condition that has triggered the event generation. The following values are available:

Value	Description
0 or DLN_ADC_EVENT_NONE	No events are generated for the current channel.
1 or DLN_ADC_EVENT_BELOW	Events are generated when voltage level on the ADC channel crosses the lower threshhold.
2 or DLN_ADC_EVENT_LEVEL_ABOVE	Events are generated when voltage level on the ADC channel crosses the higher threshold.
3 or DLN_ADC_EVENT_OUTSIDE	Events are generated when voltage level on the ADC channel falls outside of the specified range between thresholds.
4 or DLN_ADC_EVENT_INSIDE	Events are generated when voltage level on the ADC channel falls within the specified range between thresholds.
5 or DLN_ADC_EVENT_ALWAYS	Events are sent periodically with predefined repeat interval. The non-zero interval must be specified for this event type.
