Embodiment one
The flow chart of the imaging box chip amending method that Fig. 1 provides for the embodiment of the invention one, this method comprises the steps:
Specifically can be to come obtaining communication agreement and algorithm through identification, perhaps pre-stored communication protocol and algorithm commonly used be tried out one by one and obtained, and perhaps can also make the user choose communication protocol and algorithm voluntarily.Can adopt multiple prior art means to realize to the identification of communication protocol and algorithm, for example, can at first utilize oscilloscope to gather the communication waveforms when communicating between imaging device and the imaging box chip, then contrast existing communication protocol, for example contrast I
2C is (between integrated circuit; Inter-Integrated Circuit) general communication protocol etc. in agreement, 1-Wire monobus lin protocol and the industry; With characteristics such as the sequential of instrument and equipment or artificial experience analysis waveform and frequencies, to know communication protocol and algorithm between the two.This communication protocol and algorithm can be realized data write operation in the imaging box chip memory.Obtain the communication protocol of read-write chip and the routine techniques means that algorithm can adopt those skilled in the art through analysis waveform, repeat no more at this.
After getting access to communication protocol and algorithm, can adopt with the institute corresponding data fetch equipment of obtaining communication agreement and read the data in the imaging box chip.Data fetch equipment can adopt the normally used general data output of those skilled in the art instrument, can accomplish data write in the chip simply according to the corresponding communication agreement.The communication interface that data fetch equipment generally comprises controller and is connected with imaging box chip, controller are used for the transmitting-receiving of data processing and control command, are generally single-chip microcomputer; Communication interface is used to realize that chip communicates by letter with the concrete of controller, plays the effect of conversion of signals.The operation principle of data fetch equipment is: controller converts the control command that reads chip data to and meets the digital signal that communication protocol requires; By communication interface the digital signal that slave controller sends is required to convert to the analog signal that can supply chip identification according to communication protocol again; Receive, respond by chip at last; And converting the analog signal that chip is responded to digital signal through communication interface, final Be Controlled device receives and also extracts useful chip data.Because imaging box chip possibly adopt mode storaging state information data such as binary system or hexadecimal, so metric state information value is corresponding to the status information data of forms such as binary system or hexadecimal.The status information data tabulation that is specially the hexadecimal form as shown in Figure 2, generally can not these data of Direct Recognition and state information value between corresponding relation.
Because the corresponding relation between status information data and the state information value directly can not known; Just user-defined target modification value can't be directly to shining the position that should revise; So the mode that present embodiment adopts is: according to preset revise rule and make amendment after again the output state value of information judge; Carry out repeatedly, until the state information value of output with till the target modification value is consistent.Above-mentioned preset modification rule is one or more modification rules of setting or choose corresponding to the target modification value.Said method has utilized the characteristics of the exportable state information value of imaging box chip; Under the operation of imaging device, can read and print the consumptive material state information page or leaf of imaging box chip; Just state information value is verified the correctness of revising with the state information value of output.Certainly, the mode of the imaging box chip output state value of information can have multiple, for example utilizes fetch equipment to read out state information value and compares also with the target modification value and can realize decision operation.
