Abstract

Systems, devices, and methods are provided that enable the revision of RF command handling software stored in ROM, and that enable to supplementation of RF command handling software stored in ROM. Examples of the systems, devices, and methods make use of a lookup data structure stored within writable non-volatile memory.

Claims

1. A method of producing a device that comprises a processor, radio frequency (RF) communication circuitry, a non-transitory and non-volatile writable memory, and a non-transitory and non-volatile read-only memory (ROM) having a plurality of original command handlers stored thereon, wherein the plurality of command handlers are each capable of executing an RF command, the method comprising:

inputting a new command handler into the writable memory; and

programming the device to determine whether a received RF command is to be executed by the new command handler stored in the writable memory or by at least one of the plurality of original command handlers stored in the ROM.

2. The method of claim 1, further comprising:

inputting a lookup data structure into the writable memory, wherein the lookup data structure includes an identifier for the new command handler and an identifier for the command that is executable by the new command handler.

3. The method of claim 2, wherein the device is programmed to determine whether the received RF command is to be executed by the new command handler by reference to the lookup data structure.

4. The method of claim 3, wherein the device is programmed to execute the received RF command with the new command handler if the identifier for the received RF command is located in the lookup data structure and is associated with the identifier for the new command handler.

5. The method of claim 4, wherein the identifier for the new command handler is a memory pointer.

6. The method of claim 1, wherein the new command handler is a replacement command handler for at least one of the plurality of original command handlers, and wherein the device is programmed to execute the received RF command with the replacement command handler.

7. The method of claim 1, wherein the new command handler is capable of executing a new RF command not executable by the plurality of original command handlers.

8. The method of claim 1, wherein the device comprises a serial interface and wherein the new command handler and the lookup data structure are input into the writable memory through the serial interface.

9. The method of claim 8, wherein the device comprises a boundary scan architecture, and the serial interface provides access to the boundary scan architecture.

10. The method of claim 8, wherein the writable memory has a memory input/output (I/O) bus that provides read and write access to the memory, wherein the serial interface is directly externally accessible and the memory I/O bus is not directly externally accessible.

11. The method of claim 1, wherein the new command handler and the lookup data structure are input into the writable memory using the RF communication circuitry.

12. The method of claim 1, wherein the device is an analyte monitoring device.

13. A method of executing a received radio frequency (RF) command in an electrical device, wherein the electrical device comprises RF communication circuitry, a processor, a non-transitory and non-volatile read-only memory (ROM), and a non-transitory writable memory, wherein a plurality of original command handlers are stored in the ROM, each of the plurality of original command handlers being capable of executing an original RF command, and wherein a lookup data structure and at least one new command handler are stored in the writable memory, the new command handler being capable of executing a new RF command, the method being performed by the electrical device and comprising:

(a) receiving an RF command over an RF communication path;

(b) determining, at least in part by reference to the lookup data structure, an appropriate command handler with which to execute the received RF command from among at least one of the plurality of original command handlers and the at least one new command handler; and

(c) executing the received RF command with the appropriate command handler.

14. The method of claim 13, wherein the writable memory is non-volatile writable memory.

15. The method of claim 14, wherein the lookup data structure includes a command identifier for a first RF command and a handler identifier for the new RF command handler that can execute the first RF command, wherein the command identifier is associated with the handler identifier in the lookup data structure.

16. The method of claim 15, wherein the appropriate command handler is determined to be the new command handler if a command identifier for the received RF command matches the command identifier for the first RF command.

17. The method of claim 16, wherein the appropriate command handler is determined to be at least one of the plurality of original command handlers if the lookup data structure does not contain a command identifier that matches the command identifier for the received RF command.

18. The method of claim 16, wherein the lookup data structure includes a second command identifier associated with a second handler identifier for a first at least one of the plurality of original command handlers, and wherein the appropriate command handler is determined to be the first at least one of the plurality of original command handlers if the second command identifier matches the command identifier for the received RF command.

19. The method of claim 15, wherein the lookup data structure includes a plurality of command identifiers and a plurality of handler identifiers for a plurality of new command handlers, each of the plurality of command identifiers being associated with one of the plurality of handler identifiers.

20. The method of claim 15, wherein the handler identifier is a memory pointer.

21. The method of claim 13, wherein the electrical device is an analyte monitoring device.

22. The method of claim 21, wherein the analyte monitoring device is a sensor control device adapted for use in an in vivo analyte monitoring system, the sensor control device comprising a patch for coupling the sensor control device to the skin of a user and a sensor adapted for insertion through the user'"'"'s skin.

23. The method of claim 22, wherein steps (a)-(c) are performed after the sensor has been inserted through the user'"'"'s skin and while positioned in the skin.
