Abstract
The invention provides a fixture jig capable of achieving quick burning and testing. The fixture jig comprises a USB (universal serial bus) power input line and a J-link emulator. The USB power input line is connected with the J-link emulator and provides power input for the J-link emulator, the VCC (virtual channel connection) input pin of the J-link emulator is connected with a VCC output pin, the pin of the output terminal of the J-link emulator, which corresponds to the VCC input pin, is connected with the VCC pin of a chip to be burnt or tested, and the pin of the output terminal of the J-link emulator, which corresponds to a ground pin, is connected with the ground pin (GND) of the chip to be burnt or tested. Compared with the prior art, the fixture jig capable of achieving the quick burning and testing burns or tests the chip through the J-link emulator and meanwhile supplies power for the chip, thereby omitting an additional power source for burning or testing the chip and further achieving the rapid burning and testing.
Description
Technical field
The present invention relates to multichannel ammeter field, relate in particular to a kind of can fast writing and the tool fixture of inspection.
Background technology
In the prior art, the burning program of multichannel ammeter, is to realize by J-Link simulator tool.J-Link emulator is that German SEGGER company is the emulator of supporting that emulation ARM core chip is released.It adopts power supply USB power supply input, and connects computer, and output is a terminal head.When burning program, the terminal head of J-Link emulator inserts the terminal base of circuit board.Realize burning process by computer burn recording software.J-Link emulator, can on-line debugging program and burning program as a kind of emulator.But give when burning chip program, chip need to provide the power supply of 3-5V could start, be only signal input and J-link emulator provides.Therefore each burning program, must pass through the chip power supply of a Switching Power Supply to circuit board, then could pass through the burning of J-link emulator.
Like this, in actual production, just cumbersome.Need an edge joint power supply, an edge joint J-Link emulator.
Therefore be necessary to provide the tool fixture of a kind of new fast writing and inspection to solve the problems referred to above.
Summary of the invention
The present invention relates to one and only need to connect J-link emulator, without separately connecing the Multi-path electricity watch core sheet fast writing of power supply and the tool fixture of inspection.
To achieve the above object of the invention, the invention provides the tool fixture of a kind of fast writing and inspection, it comprises: a USB power input line, one J-link emulator, described USB power input line and J-link emulator are connected to it power supply input are provided, the VCC input pin of J-link emulator is connected with VCC output pin, the lead-out terminal head stitch corresponding with VCC output pin of J-link emulator is connected with the chip VCC pin for the treatment of burning or inspection, the lead-out terminal head stitch corresponding with GND output pin of J-link emulator is connected with the chip GND pin for the treatment of burning or inspection.
As a further improvement on the present invention, the tool fixture of fast writing according to claim 1 and inspection, is characterized in that, between the VCC input pin of J-link emulator and VCC output pin, is provided with a switch.
As a further improvement on the present invention, in production line burning pattern, described switch is closure state.
As a further improvement on the present invention, in bug check pattern, described switch is off-state.
Compared with prior art, the tool fixture of fast writing provided by the present invention and inspection, utilizes J-link emulator to carry out burning or inspection to chip, provides Power supply to chip simultaneously, need not be more in addition for treating that burning or checking chip connect a power supply, have realized fast writing or inspection.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing relevant of the present invention in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the circuit connection structure figure of one embodiment of the invention.
Embodiment
Describe the present invention below with reference to each embodiment shown in the drawings.But these embodiment do not limit the present invention, the conversion in structure, method or function that those of ordinary skill in the art makes according to these embodiment is all included in protection scope of the present invention.
Shown in ginseng Fig. 1, fast writing provided by the present invention and the tool fixture of inspection, utilize a J-link emulator 200, wherein, VCC input pin and GND input pin are the power supply input pin of J-link emulator 200, and in actual use, for fear of occurring driving force deficiency, VCC output pin and GND output pin are only vacant as the end for subsequent use of J-link emulator.
One USB power input line 100, one J-link emulator 200, described USB power input line 100 is connected to it with J-link emulator 200 power supply input is provided, the VCC input pin of J-link emulator 200 is connected with VCC output pin, its GND input pin is connected with GND output pin, the output pin of J-link emulator is connected to lead-out terminal head 400 by output line 300, on lead-out terminal head 400, the stitch corresponding with VCC output pin is connected to the chip VCC pin for the treatment of burning or inspection, lead-out terminal head 400 stitch corresponding with GND output pin of J-link emulator 200 is connected to the chip GND pin for the treatment of burning or inspection.
Concrete, in the time of production line operation, circuit board is not being worked only to burning chip program.Now, J-link emulator 200 can provide signal and power supply input simultaneously, and, in production line burning pattern, switch is in closure state.In the research and development of products bug check stage, ammeter in working order, close, and signal input is only provided by the power supply output of J-link emulator.So also solve in circuit board duty, prevented the problem that J-link emulator is short of power.Therefore,, in bug check pattern, described switch is off-state.
Concrete, the J-link emulator in the present embodiment can be J-link V8 emulator.
The tool fixture of fast writing provided by the present invention and inspection, utilize J-link emulator to carry out burning or inspection to chip, provide Power supply to chip simultaneously, need not be more in addition for treating that burning or checking chip connect a power supply, have realized fast writing or inspection.
Be to be understood that, although this instructions is described according to embodiment, but be not that each embodiment only comprises an independently technical scheme, this narrating mode of instructions is only for clarity sake, those skilled in the art should make instructions as a whole, technical scheme in each embodiment also can, through appropriately combined, form other embodiments that it will be appreciated by those skilled in the art that.
Listed a series of detailed description is above only illustrating for feasibility embodiment of the present invention; they are not in order to limit the scope of the invention, all do not depart from the equivalent embodiment that skill spirit of the present invention does or change and all should be included in protection scope of the present invention within.
