Abstract
A power tool having a digital control unit is provided, an interface of the digital control unit being switchable between standard operation and communication operation. In communication operation, operating data of the power tool are able to be transmitted via the interface.
Claims22
A power tool, comprising:
- a digital control unit including a microprocessor;
- and
- an electrical energy store device connected to the digital control unit via at least one conductive line, the electrical energy store device including at least one of:
- an accumulator, or a battery;
- wherein an interface of the digital control unit is switchable periodically between standard operation and communication operation, in the standard operation the digital control unit receiving at least one analog signal from the electrical energy store device via the at least one conductive line, and in the communication operation the digital control unit transmitting at least one digital signal over the at least one conductive line, the at least one digital signal including operating data of the power tool, and
- wherein the interface is switchable periodically between the standard operation and the communication operation via a periodic switchover of input pins to output pins of the microprocessor.

A method for operating a power tool, the method comprising:
- switching over an interface of a digital control unit of the power tool between standard operation and communication operation, the digital control unit including a microprocessor and the power tool further including an electrical energy store device connected to the digital control unit via at least one conductive line, in the standard operation the digital control unit receiving at least one analog signal from the electrical energy store device via the at least one conductive line, and in the communication operation the digital control unit transmitting at least one digital signal over the at least one conductive line, the at least one digital signal including operating data of the power tool;
- wherein the electrical energy store device includes at least one of:
- an accumulator, or a battery;
- and
- wherein the switching over between the standard operation and the communication operation takes place periodically via a periodic switchover of input pins to output pins of the microprocessor.
