Description of the Invention: [Technical Field] The present invention relates to an expansion device control method and an expansion device using the same, and particularly to an expansion device control method that allows a virtual expansion circuit and an actual expansion circuit to coexist. An expansion device that uses this expansion device control method. [Prior Art] In the known technology, the number of electrons controlled by a controller is often limited by the number of bits of the control signal that the controller can output. For example, if the number of bits of the output control signal is 3, only three electronic devices can be controlled. If the number of bits is 4, four electronic devices can be controlled. To control more electronic devices with fewer control bits, an extension I/O must be used. Fig. 1 is a schematic view showing the conventional technique of using an expansion circuit to control a large number of electronic components. As shown in Fig. 1, the expansion device 100 includes a controller 1〇1 and an expansion circuit 103. In this example, the controller (9) outputs a control signal having 3 control bits SSQ, S1, phantom. Without the expansion circuit 1〇3, the controller ι〇ι can only control 3 powers. Sub-device. And as the first! As shown in the figure, the control signal having the three control bits S1 to S3 can be converted into the control signal having the eight control bits tlDI to D8 through the expansion circuit 1〇3 (generally including - decoding β). The control (4) (9) can control the electronic device 8 (1〇5~119). Pastor 1~. The second__ shows the control signal (sl~s3) from the controller and the wave open/dry sound of the device number (D1~D8) _ T-. The figure below shows the slave controller. Control chart 201216722 (S1 ~ S3) and device control tfU tiger (m ~ D8) relationship diagram. Please note that in the first drawing, 'electronic device 1 to electronic device 8 (105 to 119) are low voltage, and driving, that is, when the voltage is low, it means that the electronic device is selected. As can be seen from the waveform of Fig. 2 and Table 1, the one of the electronic device 1 to the electronic device 8 (1〇5 to 119) is selected depending on the value of the control signal (S1 to S3) from the control port. For example, if the value of S0~S3 in the control signal is _ (that is, the value is 〇), the electronic device 1 is selected. If the value of S0~S3 in the control signal is 〇01 (that is, the value is 4) ), will choose the electronic device $ (10)

Similarly, the control 201216722 system "the value of the nickname SO~S2 can not be selected to the electronic device 2 (Zhejiang) even if it is 1 ,, and the value SG~S2 of the control signal cannot be single-touched even if it is _3 (109). Therefore, in the prior art, two controllers are often used to control the (four) sub-devices with and without the expansion circuit, which requires not only additional cost but also a more complicated control mechanism. SUMMARY OF THE INVENTION Therefore, the present invention is directed to providing an expansion device (four) method of using the same--continuous control of the weft sub-device, and an expansion device using the expansion device control method, regardless of whether or not an expansion circuit is required. . An embodiment of the present invention discloses an expansion device control method, which is used on an expansion device, the expansion device includes a control-and-expansion circuit, and the control method includes: (a) when the electronic device to be controlled When the number is less than a specific number, a first device control signal is formed according to a control signal from the controller to control the electronic device; and (b) when the number of the electronic device is greater than the specific number, the expansion is used. The circuit_control signal is converted to a second device control signal to control the electronic device. Another embodiment of the present invention discloses an expansion device including: a controller; and an expansion circuit coupled to at least one electronic device to be controlled; when the number of the electronic devices is less than a specific number, the controller The electronic device is controlled according to a control signal output by the controller. When the number of the electronic device is greater than the specific number, the expansion circuit converts the control signal into a device control signal to control the electronic device. 201216722 According to the foregoing embodiment, in the case of the need for the circuit board (4) circuit, the same is true - the number of the electronic devices is less than or greater than a specific number, and the specific number is selected. The logic of the device is fixed, which reduces the cost of the hardware and the low hardware. [Embodiment] Certain words are used in the specification and subsequent claims to refer to specific elements. Those of ordinary skill in the art should understand that a hardware manufacturer may refer to the same component by a different noun. This specification and the subsequent patent application do not use the difference in name as the means of distinguishing the elements, but the difference in function of the elements as the criterion for distinguishing. The "contains" material mentioned in the entire specification and the subsequent requests is intended to be "including but limited to". The term "external transfer" is used herein to include any direct and indirect electrical connection. Therefore, if the first device is lightly connected to a second device, it means that the first device can be electrically connected to the second device, or indirectly connected to the second device through other devices or connection means. Device. Figure 3 shows the waveform diagram of the expanded wire towel from the controller of the county, the second (S1 S3) from the controller and the device control signal (Dr to D8). In order to distinguish from the control signals (S1 to S3) and the device control signals (9) to (10) described in FIG. 1 , the values of the control signals in FIG. 3 are represented by S1, S3, and the device control signal is The value is represented by D1'~D8. The value of the control signal is represented by S1, ~S3. The relationship between the values of the outer and outer 'S1 to S3' and D1, and D8 is also summarized in the following table 2. According to the waveform of the figure and Table 2, it can be seen that in the expansion device 201216722 according to the embodiment of the present invention, the one to be selected is not absolutely correlated. Example:: Medium: The value of the Na signal is S1'~S3, and the value of the signal is § control machine in Figure 1^. If the control embodiment is selected, the selected one should be the electronic device 7 ( 117). But in this case, she set (D1 coffee logic level). Table 2 Edited an electronic device ====_, Qing’s

Referring to FIG. 4, in this =, when the number of electronic devices is not more than 3 (that is, the number of control miscellaneous bits is controlled), the control 11 is connected to the electronic device 1 〇5~), so 201216722 The charging circuit does not have a 'visible as-virtual expansion circuit 4Q3. In this case, when the value of S〇~S2' is 011, 'the electronic device 1 is selected (405), and when the value of S0, S2' is ιοί, the electronic device 2 (407) is selected. When s〇, ~sl, the value is 11〇, select the electronic device I: 3 (4G9). That is to say, it is equivalent to the market-made noisy SQ, ~, uncoded and used directly as the device control signal value D1, ~D3, used. It should be noted that the content provided by the present invention is not limited to when the number of electronic devices is not more than three, and the values S0 to S2' of the control subtraction are directly used as the values m, ~ (7) of the device control signals. It is also possible to change the line configuration (for example, to dispose the line or design a simple circuit), and change the relationship between the control subtracted values S0' to S2' and the values of the device control signals D1, D3. For example, 5' can make S0 correspond to D2, S1, corresponding to D1, and S2, and still correspond to D3. Thus, when the value of S0, ~S2, the value of 011 day temple is selected, not the electronic device i (4〇5), but the electronic device 2 (407). Such variations are also intended to be within the scope of the invention. When the number of electronic devices is greater than three, the block diagram of the expansion device according to the present invention can be as shown in Fig. 5. The structure is similar to the expansion device shown in the figure, which encodes the control signals s〇,~S2 from the controller into device control signals #D1'~D8, but the correspondence and the second figure and table The description of 1 is different. Please refer to FIG. 3 and Table 2 'When the value of the control signal (s〇, ~S2,) is 〇11, it will be encoded by the expansion circuit 503 into device control signals (m'~D8,) 〇lullii, ie, electronic Device 1 (505) is selected. When the value of the control signal (s〇, ~S2,) is ι〇ι, it will be encoded by the expansion circuit 503 into device control signals (D1, D8,) 1〇miu, that is, the electronic device 2 (5〇 is selected When the value of the control signal (S0, ~S2') is 11〇, it will be encoded by the expansion circuit 5〇3 into the device control signal (D1, D8') 1101U11, that is, the electronic device 3 (5〇9) is The selection logic is such that the number of electronic devices is not more than three, so that the teacher selects 201216722, the electronic device 1, 101 selects the electronic device 2, and 110 selects the electronic device 3). On the mechanism of selecting the electronic device 4 (511) to the electronic device 8 (519), the correspondence relationship can be arbitrarily changed. In the embodiment of Fig. 3 and Table 2, when the value of the control signal (§ 〇, ~ $2,) is 111, it is encoded by the expansion circuit 503 into the selection electronic device 4 (511). When the value of the control signal (S0, ~S2,) is 000, it is encoded by the expansion circuit 5〇3 into the selection electronic device 5 (513). When the value of the control signal (S0, S2,) is 1 ,, it is encoded by the expansion circuit 503 as the selection electronic device 6 (515). When the value of the control signal (s〇, ~幻,) is 〇川, it is encoded by the expansion circuit 503 into the selection electronic device 7 (517). When the value of the control signals (S0' to S2') is 〇〇丨, it is encoded by the expansion circuit 5〇3 as the selection electronic device 8 (519). However, these relationships are subject to change and are not limited to the above relationships. In summary, the operation of the expansion device according to the embodiment of the present invention can be briefly described as follows: when the number of the electronic device is less than a specific number (in this example, 3), the controller outputs a control signal according to the controller. To control the electronic device, that is, as in the embodiment of Fig. 4, the values of the control signals S0' to S2 can be directly used as the values of the device control signals 01 to D3. It is also possible to slightly change the line configuration and change the value of the control signal value 〇, 幻, and the value of the control signal D1, D3, but do not need to be controlled by the expansion circuit coding control. The job is to control the device. (4) When the number of electronic devices is greater than a certain number, the circuit converts the (4) signals SG, ~S2 into the control signals (1)'~D8 to control the electronic device. Moreover, the number of electronic cymbals is not greater than or greater than the specific wealth, and the special sewing clock (four) sub-device (material device; ^ logic is fixed.) In addition, according to the foregoing embodiment, an expansion device control method can also be obtained, and the steps are included. : when the number of miscellaneous electronic devices is less than - the special mesh number, according to: the control signal from the control signal of 201216722 to form a - device control signal to control the electronic device; and when the number of electronic devices is greater than a specific number The expansion circuit is used to convert the control into a second device control signal to control the electron beam. According to the details of the description, whether the expansion circuit or the expansion circuit is required, the same controller can be used to control the electronic device, and the specific number is selected regardless of the number of electronic devices being smaller or larger than a specific number. The logic of the internal electronics is fixed 'this can reduce the cost on the hardware, and can also reduce the design = $ noise. The above are only the preferred embodiments of the present invention. The equivalent variations and modifications of the present invention are intended to be within the scope of the present invention.
