Abstract
The utility model provides a kind of EEPROM on-line/off-line burning instrument, is made up of ARM module, SD card module, OLED module, LED module, output module, key-press module; It is characterized in that, described ARM module is controlled by described key-press module; Described SD card module is controlled by described ARM module; Described OLED module is controlled by described ARM module; Described LED module is controlled by described ARM module; The output terminal of described output module is provided with 3.3V, GND, SDA, SCL, the output of/WP signal, and input end is connected to described ARM module; Described key-press module practical function switches.The utility model is in order to realize online or off-line burning or to read 24 serial eeprom chips.
Description
Technical field
The utility model relates to the serial EEPROM technology of I2C bus read/write 24, be specifically related to a kind of by ARM file content read from SD card and is burnt to EEPROM neutralization by output module by ARM content EEPROM read and be saved in SD card.
Background technology
24 serial EEPROM are can electricity erasing and the storer of electronically written online, have that volume is little, interface simple, data preserve reliable, can rewrite online, the feature such as low in energy consumption, and be that low-voltage writes.Just because of it, there is above feature, this device can be widely used in data storage safety and the high application scenario of reliability requirement, as access control and attendance system, measure and medical instrumentation, contact type intelligent card, tax-control cash register, pre payment watthour meter or the application scenario such as multi-rate meter, water meter, gas meter and domestic electrical equipment remote controller, mobile phone, colour television set.
Due to progressively popularizing of automatic production line, the equipment of corresponding online burning EEPROM and on-line automatic burning EEPROM is not also caught up with in time, therefore, is badly in need of a kind of online burning instrument of high efficient and reliable, uses for the production of the serial EEPROM of line burning 24.
Utility model content
The utility model aims to provide the device of the serial EEPROM of a kind of on-line/off-line burning 24, in order to realize online or off-line burning or to read 24 serial eeprom chips.
To achieve these goals, basic ideas of the present utility model are: burning pattern reads by ARM the BIN file that is placed in SD card module and is burnt in EEPROM by output module; Read mode reads EEPROM by ARM, and is placed in SD card module with BIN form.
A kind of EEPROM on-line/off-line burning instrument, is made up of ARM module, SD card module, OLED module, LED module, output module, key-press module; It is characterized in that, described ARM module is controlled by described key-press module; Described SD card module is controlled by described ARM module; Described OLED module is controlled by described ARM module; Described LED module is controlled by described ARM module; The output terminal of described output module is provided with 3.3V, GND, SDA, SCL, the output of/WP signal, and input end is connected to described ARM module; Described key-press module practical function switches.
The utility model tool has the following advantages:
1, one drag two, i.e. two eeprom chips of burning simultaneously;
2, support burning and read two kinds of operator schemes;
3, online and off-line two kinds of burning patterns are supported;
4, in use procedure, complete divorced from computer;
5, the state of the real-time display instrument of LED and OLED;
6, after burning completes, the data be burnt in EEPROM are verified, to guarantee that data are accurate;
7, instrument carries/WP signal, during burning, can remove the write-protect of target device, after burning, recovers its writing protection function;
8, supported data selects burning, carries out burning by button select File;
9, the configuration information before power down is automatically recorded;
10, instrument provides power supply signal, without the need to additionally powering on to target device for EEPROM;
11, support Long-distance Control and automatically control;
Accompanying drawing explanation
Accompanying drawing described herein is used to provide further understanding of the present utility model, forms a application's part, does not form and not only limit of the present utility model, in the accompanying drawings:
Fig. 1 is global design structural drawing of the present utility model.
Embodiment
Should be appreciated that specific embodiment described herein only in order to explain the present invention, be not intended to limit the present invention.
Shown in Figure 1, the utility model is the device of the novel serial EEPROM of on-line/off-line burning 24, comprises ARM module, SD card module, OLED module, LED module, output module, key-press module; The configuration information before power down is read by ARM module when powering on; After powering on, LED and OLED shows in real time; Start ARM module after burning read the BIN file that is placed in SD card module and be burnt in EEPROM by output module; Start ARM module after reading and read content in EEPROM, and be placed in SD card module with BIN formatted file.
