Note

AINx: Analog input channels
MINx: Miscellaneous input channels. You can use VkDaqGetDeviceAttribute and VkDaqSetDeviceAttribute to read or write the MINx data source. For example, set the "dev1/MIN1" data source to VirtualCounter "VirtualCounter"
DINx: Digital input channels
AOUTx: Analog output channels
Read: Attributes can be read
Write: Attributes can be written

Use VkDaqGetChannelAttribute to Read device attributes.
For example: Read the device sampling frequency.
char inputType[65536] = {0}; int ret = VkDaqGetChannelAttribute("dev1/AIN1", "InputType", inputType, sizeof(inputType) - 1);

VkDaqGetChannelAttribute
int32_t VkDaqGetChannelAttribute(const char *chan, const char *attrName, char attrValue[], int32_t size)
Get device channel attribute value.
Use VkDaqSetChannelAttribute to write device attributes.
For example: write the device sampling frequency.
int ret = VkDaqSetChannelAttribute("dev1/AIN1", "InputType", "100000");

VkDaqSetChannelAttribute
int32_t VkDaqSetChannelAttribute(const char *chan, const char *attrName, const char *attrValue)
Set device channel attribute value.
