Detailed Description

Use this structure for attributes with min/max values or the need to have a read/write function.

Be sure to set the ZCL_ATTRIB_FLAG_FULL flag in .base.flags so the attribute is parsed with the correct type.

Field Documentation

zcl_attribute_minmax_t max

Maximum value for attribute, assumes 32-bit limit.

For string attributes, the maximum length that can be stored at value.

zcl_attribute_minmax_t min

Minimum value for attribute (currently unused until I pick a value to represent "none").

zcl_attribute_update_fn read

On an attribute read, the ZCL dispatcher will call the .read function to refresh the attribute's value before responding to the request.

Do I need a return value in the function to pass an error up?

zcl_attribute_write_fn write

On an attribute write, the ZCL dispatcher will call the .write function with a structure containing information about the write request.

See the documentation for zcl_attribute_write_fn() for the API, and the Time and Identify clusters for examples of its use.
