Definitions
- Keyboard in particular cash register keyboard, and method for commissioning and for exchanging and updating the firmware of the keyboard
- the invention relates to a keyboard, in particular a cash desk keyboard, with a keypad, a microprocessor, at least one read-only memory in which the firmware required for operating the keyboard is stored, and at least one interface for connecting the keyboard to an external device.
- the invention further relates to a method for starting up the keyboard and a method for exchanging or updating the firmware of the keyboard.
- the invention is based on the object of disclosing a keyboard in which an opening of the keyboard for the exchange or update of firmware is generally not necessary. Furthermore, a procedure for commissioning the keyboard and a procedure for exchanging or updating firmware are to be specified.
- the invention is essentially based on the idea of providing at least one programmable read-only memory in the keyboard, in which a boot program and the firmware are stored in different memory areas, in such a way that the first memory area containing the boot program is in normal keyboard operation cannot be deleted.
- the second memory area of the programmable memory containing the firmware can be electrically erased and rewritten, so that the keyboard firmware can be exchanged or updated via the keyboard interface from the outside, and thus without opening the keyboard.
- the new firmware can be transferred to the keyboard, for example, by means of a sales computer connected to the keyboard interface, sales computer denoting the computing unit which the keyboard serves as an input device in normal operation.
- the memory management of the keyboard according to the invention is advantageously designed such that this cannot take place during normal operation of the keyboard. Rather, the keyboard must be opened, as with the known keyboards, and the entire memory area must be deleted and then rewritten using an appropriate development tool (for example a hardware flashing device).
- an appropriate development tool for example a hardware flashing device.
- the memory can consist of at least two separate partial memories, the first memory area containing the boot program and cannot be deleted in normal operation and the second partial memory containing the firmware and (block by block) can be deleted and rewritten.
- the user can be informed, for example, of an acoustic message, a text message on the external device or a display on the keyboard, of the need to replace or update the firmware.
- the term external device means all devices to which the keyboard can be connected. For example, it can be a completely separate device in its own housing. However, it can also be a device in which the keyboard is integrated as an assembly.
- FIG. 1 shows the block diagram of a keyboard device according to the invention
- FIG. 2 shows the block diagram of another embodiment of the keyboard device according to the invention.
- FIG. 1 denotes a cash register keyboard, which essentially consists of a keypad 2, a microprocessor 4, a programmable read-only memory 6 in which the firmware required for operating the keyboard 1 is stored, and at least one interface 8 for connecting the keyboard to an external device 9.
- the microprocessor 4 is connected to an interface 8, which in the exemplary embodiment shown is connected to a computing unit 9 via a wire 100. Alternatively, a wireless connection is provided.
- the keyboard block 2 is connected directly to the inputs of the microprocessor 4.
- the microprocessor 4 is connected both to a main memory (RAM) 5 and to a programmable read-only memory 6, the read-only memory 6 being a flash memory.
- the programmable read-only memory 6 comprises a first memory area 10, which cannot be erased and written to during normal operation of the keyboard 1, in which the program necessary for booting the keyboard 1 is stored.
- the programmable read-only memory 6 has a second memory area 11 which contains the firmware of the keyboard 1 and which can be erased and written to in normal operation and which can be erased and written via the interface 8 of the keyboard 1.
- FIG. 2 shows an alternative embodiment of the cash register keyboard 1, in which the main memory 5 and the read-only memory 6 are integrated in the microprocessor 4. Otherwise, the structure corresponds to that of the keyboard 1 from FIG. 1.
- the management of the flash memory 6 is organized with the aid of the microprocessor 4 such that only the memory area 11 (block by block) can be deleted and rewritten during normal operation, but not the memory area 10 in which the boot program is located.
- an electrical signal is then generated in a manner known per se, which is fed to the microprocessor 4.
- the microprocessor 4 then reads e.g. the character corresponding to the respective key code or an assigned function or operation from a programmable memory (not shown) and forwards the corresponding information via the interface 8 and the line 100 to the computer 9.
- a programmable memory is a separate memory module, alternatively also the read-only memory 6 or the main memory 5.
- the boot area 12 remains active and changes to the “firmware update” operating state, which is identified in FIG. 3 by the reference number 14, ie the boot area is waiting for an update.
- This Status is displayed on an LED in the keyboard 1, not shown in the figures.
- a corresponding program is started on the computing unit 9 for exchanging or updating.
- the firmware is transferred via the interface 8 of the keyboard 1 from the external device 9 into the second memory area 11 of the programmable read-only memory 6 reserved for the firmware.
- the external device 9 is a sales computer. Alternatively, it is a maintenance computer, for example a notebook, or a special programming device to which the keyboard is connected for updates.
- the firmware area designated by 13 in FIG. 3 is started and the corresponding programs are loaded into the main memory 5, so that the keyboard 1 is then ready for operation.
- the invention is of course not limited to the embodiment described above.
- the programmable memory does not necessarily have to be a flash memory, but other electrically programmable read-only memories (such as an EEPROM) can also be used, provided that the memory organization of the keyboard is designed in such a way that in normal operation only the other firmware containing memory area is erasable and writable by an external device.
- EEPROM electrically programmable read-only memory
- the boot program being stored in a first read-only memory and the firmware being stored in a second programmable read-only memory.
- individual components such as the keyboard controller, can be omitted or additional electronic components such as LEDs can be added.
- the keyboard can be designed such that the firmware update is initiated from the connected computing unit 9. This can be done locally on site or via a network or via the Internet via remote maintenance.
