Description

[Detailed Description of the Invention] The present invention allows complex waveforms of multiple output lines to be easily created by registering, deleting, and inverting the H and L states of the waveform one step at a time during graphics on the Deinupunii screen. The present invention relates to a pulse signal generator.

Recently, when mounting electric circuits such as computers, communication devices, etc., electric parts such as IC1 resistors and coils are installed on a printed circuit board of a predetermined size, and a connector is provided on the edge of the board. It is constructed by sequentially fitting multiple sheets into the gate. However, in the past, when checking a circuit, it was necessary to assemble all the boards and put all the circuits into operation. Therefore, even if one were to try to find a partial failure, it was necessary to check each board from end to end, which was extremely time-consuming. Therefore, in such a case, it would be extremely convenient if the signal waveform to be input to a certain board to be checked could be easily created and the output waveform could also be displayed, since it would be possible to check each board.

The present invention has been made in view of the above points, and includes a display unit that displays input/output waveform status or status, and a function to program and modify output waveforms by directly viewing all input/output waveforms on the display unit. The information input circuit section has an information input circuit section and the information registered in the display section is outputted as waveform information. = a signal output circuit section that converts and outputs; a logic circuit section that performs at least programmable AND, programmable muff/l/or, and programmable timer processing on input information; a memory that stores input/output information; the display section; and an information input circuit. 1, a signal output circuit section, and a controller section that controls mutual data input/output between the logic circuit section.

Hereinafter, one embodiment of the present invention will be described based on the drawings.

In Fig. 1, (1) is a display unit that displays input and output square waves, and (2) is a display unit that programs the output waveforms of all square waves to be output while directly viewing them on the display unit (1). , and an information input circuit section consisting of a keyboard having a correction function; (3) a signal output circuit section that converts the information registered on the display section (1) into output waveform information and outputs the same; (4) A logic circuit section that performs processing such as programmable AND, programmable OR, and programmable timer for input information, (
5) is a memory for storing input/output information, and (6) is a signal input circuit section. Further, (7) is the information input circuit section (2).
), the signal output circuit section (3), the logic circuit section (4), the memory (5), the signal input circuit section (6), and the display section (1) via the display output conversion section (8). The controller section (9) is probably composed of a microcomputer that controls the input and output of information, and 9 is a group of output terminals, and QO) is a group of input terminals.

As shown in Figure @2 of the display unit (1), the first line at the top is the sequence 16 line α1), and the second to 17th lines are the output lines (121) to (12F).
The 18th line of λ is the command line (13), the 19th and 20th lines are the sub-command lines (1 country), and the first column on the left side is the output line pain line 0υ, the second column is What follows is the time axis.

Further, in FIG. 2, the mouth seal is a cursor (17), and this cursor (171) is basically moved by operating the following keys.

a, "↑" and "↓J r-J r-J keys move the cursor aη one step in the arrow direction. Using the "CR" key, the state of output rHJ (white frame shown) is moved to the position where the cursor aη was. state).

b. Move the ζ2 cursor a force above the set "H" pulse and cancel with the "CR" key.

c. ``Use the HOMEJ key to move the first cursor αη of the line.

The keys d and 1-NEGAJ have the function of inverting all data on the line where the cursor (+7) is located from H to L and from L to H.

e, Interrupt stop using IRQ f, S command (stop): Start from the beginning, 8
Stop at a point.

g, E command (end): Start from the beginning, return to the beginning at point E, continue from the beginning again, and repeat indefinitely.

h, T command: Set the unit time of 1 step using number keys, r
Set by lJ to r9J in units of 100 m5ec.

However, if it is not set, it is 100m5ec.

Next, FIG. 4 is a flowchart showing the basic operation of the apparatus according to the present invention. In Figure 4, after the start,
You will enter data by key operation, but at this point press "R".
If a key is desired to be pressed, the routine returns to "key-in" through a "routine for registering and clearing input data in the display section (1)." When the ``几'' key is pressed, the routine returns to ``key-in'' through ``routine for converting data registered in display unit 0 into output information'' and ``routine for sequentially executing output information''. In addition, "information input circuit section (2)
), when performing the operation "interrupt from", the interrupt processing routine is entered by receiving an interrupt signal while the output information is being sequentially executed, and the "key-in" operation is started.

And when you do not press the rCJ key (other than "C")
returns to the interrupt point and returns to the "routine for sequentially executing output information", and when the "C" key is pressed, the routine returns to the key-in point immediately after the start. By passing through this interrupt processing routine, re-registration, modification, etc. can be performed after execution of rRJ.

To explain the above operation in more detail with reference to the flowchart in FIG. 5, in this FIG. (1
9 represents the "routine for converting data registered in the display unit (1) into output information" in FIG. 4, and (20
) refers to a "routine that sequentially executes output information."

Next, output waveform registration, modification, command registration, execution (waveform output), and interruption will be sequentially explained based on the flowchart of FIG.

(1) How to register the output waveform Move the cursor up and down to the line of the chord you want to output.

Therefore, use the following method to sequentially register only the parts where you want the output to be in the "H" state. Regarding the state of rLJ, there is no need for any particular operation, just move the cursor Q7).

The registration method is to press the rC/RJ key, the rHJ status will be registered at the position where the cursor aη was, the RO mark will be displayed on the screen as shown in Figure 2, and the cursor ση will move one position to the right. do. If it continues to be “H”, r again.
Press the C/1'LJ key. If the next is rLJ, “=
” key moves the cursor α force one position to the right. In this case, the cursor α force is cleared on the screen, and the cursor aη is moved by one position to the right.

(2) Correction in case of mistake If you want to make a correction, move the cursor α to the place you want to correct and press the rC/Rj key. With this operation, the RO mark is erased in places where "H" has been registered, and "I(", that is, the RO mark is registered in places where it is not registered).

(31rs'J rEJ rTJ command registration rsJ
The rEJ rTJ command can be registered by directly pressing the "S", "E" or "T" key. However, rsJ
For the ' rEj command, the cursor 0η is registered only on the command line αJ and is invalid on other lines.

The ITJ command does not matter where the cursor is placed.

However, it is registered by pressing the number key of the required time after pressing the ITJ key. In this case, the number key “1”
~Press "9" to register in units of 100m5ec. Regarding this output pulse width, the unit is 100 m5 ec and the variable range is 100 to 900 m5 ec.
．． Any number of digits may be used as long as the unit is 5m5ec, and the number of digits is not particularly specified and can be determined at the time of programming.

To cancel the "S" and "E" commands, move the cursor over the character and press the rc/Rj key to cancel, then ITJ
Command changes can be made by pressing the rTJ key again and then pressing the required number.

(4) Execution (waveform output) Press the mouth 1 key.

The cursor α force can be placed anywhere, but by pressing the "R" key, all registered information will be converted into composite information data of all output codes for each step when outputting, and for all steps. Once data conversion is complete, the steps are executed sequentially from the beginning.

First, read the command line α□□□ and press “S” and “E”.
Check whether the command is registered.

If there is none, output the waveform, run the necessary timer, and continue to the next step.

If there is an r8J command, keyboard input is required. When the rRJ command is input, the program returns to the beginning and re-executes, and if any other key is used, the program continues again.

If there is an rEJ command, the process unconditionally returns to the beginning and continues again from the beginning. After that, it is repeated infinitely.

(5) Interruption midway It can be interrupted by pressing the keyboard during execution.

Then press rRJ to restart from the beginning.

Pressing the "C" key returns you to the registration routine and allows you to register, change, modify, etc.

If keys other than ``几'' and ``C'' are used, the process will restart from the point of interruption.

In the case of a timer routine, the remaining time is also executed.

(6) In addition, when scrolling is performed because the screen is not enough to be displayed, press the rRI(lHTj key to scroll to the right, and press the rL E F TJ key to scroll to the left.

Other operations are as described in the flowchart in FIG.

Assuming that the above method displays the screen as shown in FIG. 2, the output terminal (9) from the signal output circuit section (3).

Through these steps, output waveforms as shown in FIGS. 3(a), (b), and (c) are obtained.

Since the present invention is configured as described above, it can be registered in multiple sources,
It can be deleted and inverted, and therefore, multiple waveforms of multiple output lines can be easily created while looking at the relationship between each output line. In addition, various logical correspondences with input lines can be made for output. The device according to the present invention is extremely effective when used in sequence controllers, pulse simulators, debugging controllers for automatic machines, and the like.
