Description

Single Chip Computer Developing Set

Technical field

This utility model relates to Single Chip Computer Developing Set。

Background technology

The migration path that singlechip technology has been passed by nearly 20 years since development。Nowadays single-chip microcomputer has been widely used in all trades and professions, little of remote control electronic toy, the big shadow having single chip application to electron trades such as aeronautical and space technologies。Grasp the needs of this gate technique of single-chip microcomputer and teaching for helping numerous students, fan and product development person to learn rapidly, various singlechip experimental facilities are born。

The function of existing singlechip experimental facility is each variant, and form is varied。But these singlechip experimental facilities to students ' practical ability, build, debug circuit Capability Requirement all higher。Between various modules, the long period is spent in assembling, welding etc., is unfavorable for student's study to circuit theory, thus this mode is not suitable in classroom instruction。

Utility model content

For overcoming drawbacks described above, this utility model provide a kind of not only learnt easily, conveniently build experimental circuit and but also can exercise student ' manipulative ability, build, debug the ability Single Chip Computer Developing Set of circuit。

For reaching above-mentioned purpose, Single Chip Computer Developing Set of the present utility model, including a casing and the case lid being hinged on described casing；

Battery chamber is set at described box bottom, in described battery chamber, is provided with a Switching Power Supply and rechargable power supplies；

Described battery chamber is provided with the supporting plate being hinged on casing side, described supporting plate is provided with microcomputer development plate, FPGA development board and bread board；

Described microcomputer development plate at least presets single-chip microcomputer, clock circuit and reset circuit, I/O mouth；

Described FPGA development board at least presets FPGA, clock circuit and reset circuit, I/O mouth；

Described case lid is hinged with display panel, described display panel is provided with 7 segment numeral pipes, 1602 LCDs, color LCD screen, LED dot matrix display screen；

Described bread board is provided with expansion module；

Wherein, described Switching Power Supply and rechargable power supplies provide power supply by attaching plug to microcomputer development plate and/or FPGA development board；

The I/O mouth of described microcomputer development plate and FPGA development board leads to bread board and/or display screen by winding displacement。

Preferably, described microcomputer development plate and FPGA development board are positioned at bread board both sides。

Preferably, described rechargable power supplies is lithium battery, and the charging circuit at described lithium battery is serially connected with and overcharges thermoswitch, and the described thermoswitch that overcharges is arranged in lithium battery。

Preferably, being serially connected with overheated thermoswitch at described lithium battery in the supply line of microcomputer development plate and FPGA development board, the nearly lithium battery of described overheated thermoswitch is arranged。

Adopt this utility model of said structure, single-chip microcomputer is organically combined with FPGA plate and bread board, and by modularitys such as power supply, display screen, expansion circuit, and connect with winding displacement, overall structure is simple, both can learn and build the various basic experiment on textbook relatively easily, it is also possible to utilize bread board and expansion circuit to build other experimental circuit various, with exercise student ' manipulative ability, the ability building, debugging circuit, facilitate study and the exploitation of SCM&FPGA。

Accompanying drawing explanation

Fig. 1 is the schematic diagram of single chip part in this utility model。

Fig. 2 is schematic diagram of the present utility model。

Detailed description of the invention

Below in conjunction with drawings and Examples, this utility model is further described。

As depicted in figs. 1 and 2, Single Chip Computer Developing Set of the present utility model, including a casing and the case lid being hinged on described casing；This structure easily arranges and builds various experimental circuit。

Battery chamber is set at described box bottom, in described battery chamber, is provided with a Switching Power Supply and rechargable power supplies；Utilize both power supplys, it is possible to achieve the circuit demonstration under classroom and class

Described case lid is hinged with display panel, described display panel is provided with 7 segment numeral pipes, 1602 LCDs, color LCD screen, LED dot matrix display screen；These display screens are fixed on display panel, not only improve and show to study, be conducive to again building circuit；

Described bread board is provided with expansion module；Wherein, expanding module can be ds1302 digital clock, ds18b20 temperature detection, SD card module, USB module, ultrasonic ranging, radio, mp3 decoder module etc.。

In order to better utilize bread board, microcomputer development plate and FPGA development board should be positioned at bread board both sides, as shown in Figure 2。

As further improvement of the utility model, rechargable power supplies should elect lithium battery as, but the battery caused to prevent lithium battery from overcharging or excessively to put is overheated, to produce blast, charging circuit at described lithium battery is serially connected with and overcharges thermoswitch, and the described thermoswitch that overcharges is arranged in lithium battery；Being serially connected with overheated thermoswitch at described lithium battery in the supply line of microcomputer development plate and FPGA development board, the nearly lithium battery of described overheated thermoswitch is arranged。

Above; being only preferred embodiment of the present utility model, but protection scope of the present invention is not limited thereto, any those familiar with the art is in the technical scope that the invention discloses; the change that can readily occur in or replacement, all should be encompassed within protection domain of the present utility model。Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claim defines。
