user_device_info()
Procedure
- Determine the list of supported features for each device. The list of supported features must be a subset of those supported by the protocol. Also, determine the list of supported memory locations.
- Memory locations sharing the same characteristics and which can be read contiguously should be grouped to form a domain.
- Assign a domain index to each domain. If using standard addressing, each domain should also be assigned a name of up to 16 characters. The domain index must be between '0' and '254', and should be sequential. Each domain must have a unique index (and where standard addressing is used, a unique name).
- Determine the value used to identify the first memory location in each domain.
- Determine the number of elements in each domain.
-
Determine the form of addressing used to reference an element in the domain. The available forms are:
TOOLKIT_BIT (1 bit long)
TOOLKIT_BYTE (1 byte long)
TOOLKIT_WORD (2 bytes long)
TOOLKIT_4BYTE (4 bytes long)
TOOLKIT_8BYTE (8 bytes long)
