DLN_ADC_GET_ALL_VALUES Command and Response

The DLN_ADC_GET_ALL_VALUES command retrieves current voltage values from all enabled ADC channels of your DLN-series adapter.

DLN_ADC_GET_ALL_VALUES Command

Go to response

 typedef struct
 {
    DLN_MSG_HEADER header;
    uint8_t port;
 } __PACKED_ATTR DLN_ADC_GET_ALL_VALUES_CMD;

Parameters:

header

Defines the DLN message header DLN_MSG_HEADER. The header contains several predefined fields and is used to identify and route messages. You must fill the following fields before sending the command:

Field	Description
size	The size of the message. Must be equal to the size of the DLN_ADC_GET_ALL_VALUES_CMD structure.
msgId	Identifies the message. For the DLN_ADC_GET_ALL_VALUES command it must be set to 0x060B. You can use the DLN_MSG_ID_ADC_GET_ALL_VALUES constant.
echoCounter	Can be used to link a command 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.

port

An ADC port to retrieve the information from.

DLN_ADC_GET_ALL_VALUES Response

Go to command

The adapter sends the DLN_ADC_GET_ALL_VALUES response after the DLN_ADC_GET_ALL_VALUES command execution. The response contains current voltage values from all enabled ADC channels of your DLN-series adapter.

typedef struct
{
    DLN_MSG_HEADER header;
    DLN_RESULT result;
    uint16_t channelMask;
    uint16_t values[DLN_ADC_CHANNEL_COUNT_MAX];
} __PACKED_ATTR DLN_ADC_GET_ALL_VALUES_RSP;

Parameters:

header

Defines the DLN message header DLN_MSG_HEADER. The response header contains the following fields:

Field	Description
size	The size of the message. It is equal to the size of the DLN_ADC_GET_ALL_VALUES_RSP structure.
msgId	Contains the message id. For the DLN_ADC_GET_ALL_VALUES response it is set to 0x060B. The DLN_MSG_ID_ADC_GET_ALL_VALUES constant can be used to check the message ID.
echoCounter	Links a command to a response. The echoCounter value is copied from the respective command header.
handle	A handle to the DLN-series adapter. You can use the handle field to determine the adapter that have sent the response.

result

Contains the result of the command execution. For DLN_ADC_GET_ALL_VALUES command DLN-series adapter can return the following result values:

Return Code	Description
DLN_RES_SUCCESS	Current voltage levels on all enabled ADC channels of your DLN-series device have been successfully retrieved.

channelMask

A 16-bit mask. Each of the bits corresponds to an ADC channel of the port. This parameter contains currently enabled ADC channels of your DLN-series device.

values

An array. Each of its elements contains current voltage value on one of the enabled ADC channels of your DLN-series adapter.
