Abstract

PURPOSE:To perform the input setting of a large amount of data by providing a data setting switch to set the data to be written on a nonvolatile memory and a data write switch to perform the write of set data. CONSTITUTION:On the upper plane of a main body 1, the address of a built-in nonvolatile memory and data display parts 3 and 4 to display the content of the data are provided, and step-up switches 1a, 1a and 2a, 2a and step-down switches 1b, 1b and 2b, 2b are provided on each display part. Furthermore, the setting switch 5 to perform the write of the data and a write switch 6 to be operated at the time of writing are provided. The address of the memory is designated by operating the input switches 1a-2b, and the data displayed on the display part 4 is stored in the address corresponding to the memory. In such a way, it is possible to perform the input setting of a various kinds of data compared with a dip switch, and to reduce a packaging area on a circuit board.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a novel data setting unit with a built-in CPU.

[Conventional technology]

In electronic devices with a built-in CPU, dip switches are widely used to externally change program operations stored in advance. There are various types of switches, such as those separated every 4 bits, and those that are converted into BCD code or decimal code every 4 bits, but the switches themselves are all composed of mechanical mechanisms, and once the data is Once set, it has a function to hold the data, and can give two types of information by turning on/off one contact, and if it has n contacts, two types of information can be input to the CPU. .

These dip switches are used to set the mode of electronic devices, select speech synthesis phrases, and register passwords and phone numbers. Because of the many advantages of using dip switches, electronic devices are now equipped with more and more dip switches.

However, as the number of data settings increases, a larger number of dip switches are required, and as the number of digits of data increases, the size of the dip switch increases.Therefore, improvements are desired. ing.

[Problem to be solved by the invention]

The present invention has been made in view of the above circumstances, and it is an object of the present invention to provide a data setting unit that is capable of inputting and setting a large number of data by taking advantage of the ease of input setting of a dip switch.

[Embodiment] An embodiment of the present invention will be described below with reference to the accompanying drawings.

FIG. 1 is a plan view of the data setting unit A. On the top surface of the main body 1 with connection terminals 7 on the side, there are data for displaying addresses of the built-in non-volatile memory and data contents. A display section 3.4 is provided, and each display section includes step-up switches la, la and 2a,
2a, step down switch la, la and 2b, 2b
has been established.

5 is a setting switch for writing data;
6 is a write switch operated during writing.

In the illustrated example, 8-bit addresses and data can be stored in the internal nonvolatile memory, but the present invention is not limited to this example.

FIG. 2 shows the configuration of the internal circuit of the present invention, which includes a CPU 10 for data setting, a RAM 11, and an EEFROMI as a nonvolatile memory for storing data.
It has 2 built-in.

The input keys correspond to the step-up and step-down switches la to 2b mentioned above, and the display corresponds to the two-digit display window 3.4 in the above example, and the L
It is formed by ED or LCD.

According to the data setting unit of the present invention, the address of the memory 12 is specified by operating the input switches la to 2b, and in that case, the data displayed on the display section 4 is stored in the corresponding address of the memory, The input data is sent to the host computer as necessary and used for appropriate program control.

FIG. 3 100-108 is a flowchart showing the procedure for inputting and setting data using the embodiment shown in FIG.
The address and data are set and the data is stored by operating the step up switch and step down switch provided in the .

In addition, when configuring the data setting unit of the present invention having the above configuration, in the simplest case, an address is not necessary and only data is required. is stored.

Furthermore, when configuring the unit of the present invention, it can be easily mounted on a circuit board if it is formed into a dual in-line type with a plurality of connection terminals protruding from both sides of the unit body. Note that the switch for inputting and setting the address and data is not limited to the push button type.

〔Effect of the invention〕

As explained above, according to the data setting unit of the present invention, compared to a dip switch, a wide variety of data can be input and set, and the mounting area on the circuit board can be reduced.
