Definitions
- the present invention relates to a control device and a method for detecting an operation of operating elements integrated in sensor circuits, in particular touch-sensitive and / or proximity-sensitive touch switches, by a user.
- the detection of an operation of integrated in sensor circuits controls by a user includes in particular in the case of a variety of such controls or sensor circuits in conventional control devices a large amount of time and power on the part of the microcontroller.
- Software actions such as analog-to-digital conversion, changing the state of the control signal generator to generate a pulse signal for the sensor circuits, and the like are required for each operation element.
- a microcontroller for executing the application software and another microcontroller for detecting an actuation of the controls are used and / or the number of controls is limited by the performance of the microcontroller.
- the invention is therefore based on the object, an improved control device and an improved method for detecting an actuation of in
- the solution according to the invention is intended to process a larger number of operating elements and / or to allow a smaller number of microcontrollers or the use of less powerful microcontrollers.
- the invention is based on the idea of using an operating element, which is normally present anyway, for detecting an actuation of operating elements integrated into sensor circuits by a user, thereby relieving the load on the microcontroller itself.
- an operating element which is normally present anyway, for detecting an actuation of operating elements integrated into sensor circuits by a user, thereby relieving the load on the microcontroller itself.
- control device further comprises an analog-to-digital converter having the plurality of signal inputs. Ie. the measurement signals of the sensor circuits are input to an analog-to-digital converter and digitized. If the sensor circuits already provide digital measurement signals, can be dispensed with the analog-to-digital converter in the control device.
- the memory access device has an internal register.
- the memory access device is preferably a direct memory access (DMA), a data transfer controller (DTC) or the like.
- the memory access device is designed to generate a control signal when the measurement results of all connected sensor circuits are stored in the main memory. Due to this control signal, preferably the generation of the control signal for activating the sensor circuits by the control signal generator can be interrupted so that the sensor circuits are deactivated.
- control device further comprises a timer for outputting a control command to the control signal generator for generating the control signal and / or triggering of the analog-to-digital converter.
- the method according to the invention for detecting an actuation of operating elements integrated into sensor circuits by a user comprises the steps of: outputting a control signal to the sensor circuits in order to put the sensor circuits containing the operating elements into an active state; Inputting measurement signals of the sensor circuits into different signal inputs; and storing measurement results corresponding to the received measurement signals by means of a memory access device in a main memory.
- FIG. 1 is a representation of a control device according to an embodiment of the invention, illustrating the structure and operation of a control device according to the invention.
- FIG. 2 is a timing diagram for illustrating the operation of FIG.
- Fig. 1 shown control device.
- the control device shown in Fig. 1 may be used, for example, for detecting operation of controls of a home electronic appliance (e.g., laundry treating machine, dishwasher, hob, stove, microwave oven, refrigerator and / or freezer, etc.) by a user.
- the controls are, for example, touch and / or proximity sensitive pushbuttons (e.g., capacitive, inductive, optical, piezoelectric, etc.).
- touch and / or proximity sensitive pushbuttons e.g., capacitive, inductive, optical, piezoelectric, etc.
- the invention is not limited to these fields of application.
- the control device comprises a hardware area A1, which contains the microcontroller and the peripheral components, and a software area A2.
- a hardware area A1 which contains the microcontroller and the peripheral components
- a software area A2 In an external area A3 outside the control device is a plurality of sensor circuits S1 ... Sn, each containing at least one control element B1 ... Bn that can be operated by a user.
- the hardware area A1 has a timer 12, which is controlled by a software command 10.
- the timer 12 is connected to a control signal generator 14 and an analog-to-digital converter 16 so that it can trigger these two components.
- the control signal generator 14 outputs a control signal with which the connected sensor circuits S1... Sn are put into an active state in which they can recognize an actuation of their operating elements B1... Bn by a user.
- the control signal is, for example, a pulse width modulated (PWM) control pulse.
- PWM pulse width modulated
- the analog-to-digital converter 16 has a multiplicity of signal inputs 18.
- a sensor circuit S1... Sn can be connected to each of these signal inputs 18.
- the sensor circuits S1 ... Sn enter the analog-to-digital converter 16 via these signal inputs 18 their analog measurement signals, so that they are digitized.
- the analog-to-digital converter 16 is connected to a memory access device, which in this embodiment is designed as a memory direct access DMA with an internal register.
- the direct memory access DMA has, in particular, a first channel 20, in which the digitized measurement signals as
- Measurement results are cached, and a second channel 22 to increase the internal register.
- the first channel 20 of the direct memory access DMA is connected to a random access memory (RAM) 24 in order to store the measurement results in it.
- the microcontroller (not shown) of the control device can then retrieve and evaluate the measurement results from this main memory 24.
- step a the software 12 first starts the timer 12 (step b). The timer 12 then sends a control command to the control signal generator 14 (step c) to generate a control signal (eg, a control pulse) to activate the sensor circuits S1 ... Sn (step d). This control signal is then sent to the sensor circuits
- step e After activating the sensor circuits S1... Sn, the timer 12 triggers the
- Analog-to-digital converter 16 (step f). so that it can receive the analog measuring signals of the sensor circuits S1 ... Sn via its signal inputs 18 (step g).
- the signal inputs 18 are successively released individually, so that all connected to the control device sensor circuits S1 ... Sn can be scanned and their measurement signals can be digitized.
- the measurement signal digitized by the analog-digital converter 16 (step h) of the enabled signal input 18 is forwarded as a measurement result to the first channel 20 of the memory direct access (step i), in which it is buffered before it is stored in the working memory 24 ( Step k).
- the analog-digital converter 16 After storing the measurement result in the working memory 24 (step k), the analog-digital converter 16 sends a control command to the second channel 22 of the memory direct access (step I), so that this the internal register of
- step m Direct memory access
- step n the second channel 22 of the memory direct access returns a corresponding control command to the analog-to-digital converter 16 (step n) to enable the next signal input 18 according to the incremented register and to receive the measurement signal of the next sensor circuit S1... Sn and digitize.
- the steps c to n are repeated in a first process loop x1 until the measurement results of all the sensor circuits S1... Sn connected to the control device are received, digitized and stored in the main memory 24. If the measurement results of all sensor circuits S1... Sn are detected in this way (step o), then the first channel 20 of the memory direct access sends a corresponding control signal to the software (step p).
- the software terminates the acquisition (step q) and interrupts the control of the timer 12.
- the microcontroller can retrieve the measurement results stored in the working memory 24 (step r) and further evaluate.
- the process loop x2 with the steps b to r is repeated in a predetermined time interval in order to permanently monitor an actuation of the operating elements B1... Bn.
- the shape of the measurement signals generated by the sensor circuits S1 ... Sn depends on the type of control elements B1 ... Bn (eg capacitive touch switches) and the structure of the sensor circuits S1 ... Sn. If the sensor circuits S1... Sn are designed to provide digital measurement signals, the analog-to-digital converter 16 can be dispensed with. The signal inputs 18 may then be connected to a simple register or directly to the first channel 20 of the memory direct access DMA.
