Description

Program method of memory

1 is a block diagram for performing a program method of a conventional memory.

2 is a flowchart for performing a program method of a memory according to the present invention.

The present invention relates to a method of programming a memory, and more particularly, to a method of programming a memory program and data in a main micom in a set and to program the data in the memory when the power is first turned on during the mass production of the set. will be.

Herein, the memory corresponds to both a read only memory (ROM) and a random access memory (RAM). In particular, the ROM includes a programmable ROM (PROM), an erasable PROM (EPROM), and an electrically erasable PROM (EEPROM). And the like.

FIG. 1 is a block diagram for performing a conventional method of programming a memory, and is referred to as a memory jig (JIG) 100.

1 is a power supply unit 101 for converting to direct current when power is applied through a power cord, a power switch 102 for providing the output voltage of the power supply unit 101 to each unit by turning on / off, and A microcomputer 103 for programming data to a memory when supplied and a program start signal is input, a memory start switch 104 for applying a memory program start signal to the microcomputer 103, and a light emitting to be turned on when programming to the memory is completed A light emitting diode (hereinafter referred to as LED) 105 and a predetermined memory socket 110 into which a predetermined memory can be inserted.

It is assumed here that six memories are programmed at a time.

In FIG. 1 configured as described above, the microcomputer 103 is a microcomputer-only microcomputer that stores a memory drive program and data to be written to the memory.

When the power cord is plugged into an outlet, the power supply 101 converts alternating current inputted through the power cord into direct current, and when the power switch 102 is turned on, the first to the first plugs plugged into the microcomputer 103 and the memory socket 110. 6 Supply power to the memory 111-116.

When the memory start switch 104 is turned on, the microcomputer 103 initializes the first to sixth memories 111 to 116 and simultaneously writes data or programs to the first to sixth memories 111 to 116. .

When the programming is completed after a predetermined time after the start of the program, when the LED 105 is turned on to notify the completion of the program, the program completed memory may be extracted and inserted into the memory case.

However, in FIG. 1, a memory jig must be manufactured separately, a memory program dedicated microcomputer is separately required, and the programmed memory must be stored separately in a memory case. In addition, before the mass production of the set, the worker has to work as many times as he wants to mass produce, and then the manual insertion and manual insertion had a large time and cost loss.

The present invention is to solve the above problems, an object of the present invention is to program the logic to be programmed in the memory of the main microcomet of the set, and when the power of the first set the program in the memory by a separate dedicated microcom and memory case and There is no need to make a separate memory jig to provide a memory programming method that saves time and money.

The memory programming method according to the present invention for achieving the above object is the step of pre-programming the data to be programmed into the memory to the set of main microcomputer, and if the power is turned on for the first time in mass production, all the data in the memory Determining whether the initial data is initial data, stopping the memory program process if all the data in the memory is not the initial data, and initializing the memory if all the data is the initial data, and when the memory is initialized, the data to be programmed into the memory from the microcomputer. And a step of notifying the completion of the program by using a display device when the program is completed in the memory.

Hereinafter, a preferred embodiment of a memory program method according to the present invention will be described in detail with reference to the accompanying drawings.

2 is a flowchart for performing a program method of a memory according to the present invention.

According to the present invention, when a program and data to be programmed in a memory are programmed in a set of main microcomputers and the first power is turned on during mass production, the program is determined whether or not data is already programmed in the memory to be programmed regardless of whether the memory start switch is turned on or off. If it is not determined, program and program the data in memory.

That is, when the power of the set is first turned on, the start address of the memory is read (step 201).

Then, it is determined whether the data of the read address is FF (step 202).

The initial data in memory before programming is FF. Therefore, if the data from the start address to the last address of the memory are all FF, it means that nothing is programmed in the memory.

Therefore, if it is determined that the data of the address read in step 202 is FF, it is determined whether the address read in step 201 is the last address (step 203).

If it is determined in step 203 that the address is not the last address, the process returns to step 201 to read the next address. Then, it is determined whether the data of the address read again is FF.

At this time, if the data of the read address is not FF, it means that the data is already programmed in the memory.

On the other hand, if the address read in the step 203 is the last address, all data in the memory means FF. Therefore, data to be written to the memory from the microcomputer is read (step 204) and programmed into the memory (step 205).

When the program is completed, the program completion status is notified on the screen by using the on-screen display function or the completion status is notified by using the LED lamp, and then a check operation is performed in the memory (step 206).

At this time, the capacity of the microcomputer required to program the memory is about 30 bytes, so the capacity of the microcomputer is negligibly small. Therefore, the capacity of the microcomputer does not matter much.

As described above, according to the memory programming method according to the present invention, the logic to be programmed into the set of main microcomputers is programmed in advance. This eliminates the need for a separate memory jig and eliminates the need for a dedicated microcomputer and memory case. In addition, there is no need to insert or pull the memory into the jig to program the memory, saving time, cost, and power consumption.
