Description

A kind of embedded board of MINI PCI-E interface

Technical field

The utility model relates to a kind of universal Embedded System Experiment development board, may be used for teaching and product development field.

Background technology

In order to adapt to the development of science and technology, the embedded microprocessor such as single-chip microcomputer, ARM is widely used.And Embedded study, be only not only learning software programming, also need to learn hardware design, need the support of hardware.And development board just provides hardware supported, but present development board major part is all be welded on circuit board by multiple function, can not dismantle and can not change, and when causing will learning or researching and developing New function, needs to redesign hardware, inefficiency and easily makeing mistakes.

Also have some experimental boxs, they are that several function is separate separately, but are also welded on same circuit board, and the row's of extraction pin, use this module by using the mode of wire link block row pin.This kind of experimental box line is loaded down with trivial details, very easily makes mistakes, and can not carry out well learning and developing.

Summary of the invention

In order to overcome the deficiency of present development board, the utility model provides a kind of embedded board of MINIPCI-E interface, can directly insert corresponding peripheral module, to reduce complexity and chance of makeing mistakes, improves study and development efficiency.

The utility model solves the technical scheme that its technical matters adopts: the embedded board of MINIPCI-E interface is divided into mainboard and peripheral module two large divisions.Wherein mainboard comprises microprocessor, also includes power circuit simultaneously, downloads debug circuit, further comprises the MINIPCI-E interface that one or more is positioned at development board surrounding.Microprocessor can be the microprocessor of monokaryon or multinuclear, MINIPCI-E interface be then integrated with USART interface, SPI interface, IIC interface, USB from interface, USB main interface, analog to digital conversion (ADC) interface, digital-to-analog conversion (DAC) interface, audio interface, universal input export (IO) interface, timer interface, catch interface, power interface one or more, this MINIPCI-E interface is non-standard interface.Peripheral module is then one piece of separate circuit board, containing MINIPCI-E interface.Use MINIPCI-E interface between mainboard and peripheral module, and connected by simple plug, such mainboard just can identify and control peripheral module.If MINIPCI-E number of ports quantity not sufficient, the MINIPCI-E interface quantity of embedded main board can be increased by interfacing expansion module, be extended to the MINIPCI-E interface of multiple identical function, to access more peripheral modules simultaneously.Peripheral module can be LED module, display module, communication module, memory module, motor module, power module, clock module, charactron module, analog-to-digital conversion module, D/A converter module, mixed-media network modules mixed-media, charging module, audio-frequency module, sensor assembly, infrared module, wireless module and interfacing expansion module.That is, when developer has learnt modules A, can modules A be taken off, and change module B, just can complete study and the exploitation of module B.Also first can plug interfacing expansion module, then access peripheral module A and peripheral module B simultaneously, just can control these two peripheral modules simultaneously.The interface that the utility model uses can be MINIPCI-E interface, also can be pci interface.

The beneficial effects of the utility model are: mainboard and peripheral module wide variety, have multiple combination mode, and developer can utilize different combinations, and just can change the peripheral module of various function by simple plug operation, to carry out learning or researching and developing.Like this, developer's few chance on signal wiring is made mistakes, convenient and practical, and improves Product repeat using rate and development efficiency.

Embodiment

In order to make the purpose of this utility model, technical scheme and advantage more clear, below in conjunction with accompanying drawing, the utility model is further described.Following content is only lifted a concrete case study on implementation and is described, practical for explaining, and is not used in restriction the utility model.

With reference to Fig. 1, embedded board 100 comprises mainboard 20 and several peripheral module (non-label).

With reference to Fig. 2, embedded main board comprises microprocessor 201, power circuit 202, downloads debug circuit 203 part.Also comprise MINIPCI-E interface 204 and 205, each several part is all integrated in mainboard 20.Microprocessor 201, by monokaryon classification, can be 8051, AVR, ARM7, ARM9, ARMCrotex-M3, ARMCortex-M4 etc., by double-core classification, can be LPC4357 etc.Power circuit 202 can be produced by voltage stabilizing chip or USB power source, and is finally formed by filtering netwok filtering.Downloading debug circuit 203 can be ISP, JTAG, SWD circuit, for the burning of final code.

With reference to Fig. 3, peripheral module 30 includes corresponding functional circuit 301 and MINIPCI-E interface 302.According to difference in functionality classification, can be LED Presentation Function, communication interface function, memory function, DC motor Driver function, driving stepper motor function, power boost function, power voltage step down function, time clock feature, Presentation Function, input function, analog-digital conversion function, analog conversion function, network function, charge function, audio-frequency function, sensor function, radio function etc.

On stream, select a peripheral module 30, be connected to MINIPCI-E interface 204 or MINIPCI-E interface 205 place of mainboard 20 by MINIPCI-E interface 302.Write with debugging software after, namely microprocessor can read and controls corresponding peripheral module 30.Pull up peripheral module 30, change another peripheral module B, write with debugging software after, namely microprocessor can read and controls corresponding peripheral module B.In whole process, need to develop which peripheral module and just change which peripheral module.If need to plug multiple peripheral module simultaneously, need first to use interfacing expansion module, MINIPCI-E interface 204 is expanded increases number, then connects required peripheral module simultaneously.Finally, the software write, can control multiple peripheral module simultaneously.

In whole development process, developer does not need welding circuit, removes the trouble that hardware debug produces from.Meanwhile, need to develop what function and just change which type of peripheral module, and do not need to connect wire.Finally reach convenient and practical effect, and improve Product repeat using rate and development efficiency.
