It is parsed into the hexadecimal data that picture signal generator can identify and the protocol encapsulation that can be identified according to picture signal generator
Into UDP message bag；
Step 3：UDP message bag after encapsulation is issued in MIPI modules to be measured by picture signal generator.
In such scheme, the edit format of control routine file described in step 1 is：Rxx xx xx xx xx ...,
Delay xx, wherein, R represents the register of MIPI modules, and the xx that R is followed by represents the register address of MIPI modules,
All xx after MIPI module register address represent the data that write in the MIPI module registers；Delay xx represent to prolong
When the xx seconds.
In such scheme, hexadecimal data described in step 2 includes the first character section of two segment datas, wherein first paragraph
Represent that notification image signal generator issues parameter, second byte representation MIPI to be measured of first paragraph with what type of instruction
The register address of module, the data length behind the 3rd byte representation of first paragraph, the 4th byte of first paragraph start
Represent data；Second segment data represent that notification image signal generator performs delay operation and delay time.
In such scheme, preceding 2 bytes of agreement described in step 2 are protocol command word 0x02,0x50, the 3rd byte and
4th byte is the length of packet, and the 5th byte and the 6th byte are the total length of the hexadecimal data, the 7th byte and the 8th
Byte is start byte of the data in the hexadecimal data in packet, and the 9th byte to the 251st byte is filling institute
State the data field of hexadecimal data.
In such scheme, the step 3 still further comprises, described in the ARM nucleus modules reception of picture signal generator
UDP message, the UDP message is then sent to MIPI modules to be measured by the single-chip microcomputer of picture signal generator.
Relative to prior art, beneficial effects of the present invention：
1) control routine of prior art is added in the SCM program of picture signal generator, per newly plus a
MIPI modules are it is necessary to go out the SCM program of a version, and the control routine of the present invention is in host computer upper level applications
Interior realization, without changing SCM program, reduce the SCM program version quantity of picture signal generator, convenient management；
2nd, prior art often goes out the SCM program of a version, and picture signal generator will upgrade the list of original early version
Piece machine program, because picture signal generator is large number of, upgrading expends the time, and the present invention only need to be in host computer upper layer application
The different MIPI control routine files of addition in program, it is not necessary to upgrade SCM program, reduce picture signal generator
Single-chip microcomputer upgrades number, saves the time；
3rd, the present invention need not add control routine logical process as prior art in SCM program, reduce
The SCM program size of code of picture signal generator；
4th, MIPI control routine files are employed in the present invention, this document has stronger scalability.

Individual picture parameter editing interface is performing MIPI module displays pictures according to specific format editing MIPI control routine files
During switching, host computer procedure is by the control routine document analysis of the individual picture into the monolithic function in picture signal generator
The hexadecimal data of identification and according to the identification of monolithic function protocol encapsulation into UDP message bag, then ARM nucleus modules are read
Corresponding UDP message is simultaneously sent to single-chip microcomputer, by the real time down of chip microcontroller MIPI module individual picture control routines, and
Single-chip microcomputer is no longer responsible for issuing the logical process of data.
A kind of method of transmission MIPI module individual picture control routines disclosed by the invention, specifically comprises the following steps：
Step 1：Host computer is by network connection picture signal generator, and before individual picture test, user is upper
According to testing requirement, (such as power supply is set, common electric voltage is set, sequential is set, mould in the parameter editing interface of the individual picture of machine
Group identification number, the information such as gamma parameter) individual picture to be measured to each be controlled code file (.spc files,
The abbreviation of single picture individual picture files) editor, and the control routine file editted is preserved, preserved
Control routine file afterwards can be bound with corresponding individual picture.
The edit format of above-mentioned .spc individual pictures control routine file is：
Rxx xx xx xx xx ..., Delay xx, wherein, R represents MIPI module registers, and the xx that R is followed by is represented
MIPI module register address, all xx after MIPI module register address represent to write in the MIPI module registers
Data；Delay xx represent the delay xx seconds.
Embodiment：Configure the power information " 3C of 05 C0 E0 of RBA, 62 D3 81 35 of MIPI modules individual picture to be measured
01 06, Delay 100ms ".
The meaning that " 3C 01 06 of 05 C0 E0 of RBA, 62 D3 81 35 " is represented is by 0x05 0xc0 0xe0 0x62
This 10 data of 0xd3 0x81 0x35 0x3c 0x01 0x06 sequentially write BA registers, and after write-in, module can is matched somebody with somebody
Put correct module power supply output；" Delay 100ms ", represent that 100 milliseconds of delay carries out other operations again.
Step 2：When performing the individual picture switching action, host computer is literary by above-mentioned .spc individual pictures control routine
Part is parsed into the hexadecimal data of the monolithic function identification in picture signal generator, and according in picture signal generator
The protocol encapsulation of monolithic function identification is into UDP message bag.
In such scheme, the hexadecimal data includes two segment datas, and the wherein first character section of first paragraph represents to accuse
Know that picture signal generator issues parameter with what type of instruction, second byte representation MIPI modules to be measured of first paragraph
Register address, the data length behind the 3rd byte representation of first paragraph, the 4th byte of first paragraph start to represent number
According to；Second segment data represent that notification image signal generator performs delay operation and delay time.
Embodiment：By power information " 05 C0 E0 of RBA, 62 D3 81 35 3C 01 06, Delay of individual picture
100ms " is converted into the hexadecimal data of the monolithic function identification in picture signal generator：By " the C0 E0 62 of RBA 05
The 3C 01 06 of D3 81 35 " are converted to " 0x39 0xBA 0x0A 0x05 0xC0 0xE0 0x62 0xD3 0x81 0x35
0x3C 0x01 0x06 ", " 0x39 " informs that single-chip microcomputer issues parameter with what type of instruction, and 0xBA is register address,
0x0A is data length below, followed by 10 bytes be data content；By " Delay 100ms " are converted to " 0x00
0x00 0x02 0x64 0x00 ", " 0x00 0x00 0x02 " inform that single-chip microcomputer performs delay operation, and byte representation below prolongs
When the time.
In such scheme, protocol definition is as follows used by the hexadecimal data is packaged into UDP message bag：It is described
Preceding 2 bytes of agreement are protocol command word 0x02,0x50, the 3rd byte and the length that the 4th byte is packet, the 5th byte and
6th byte is the total length of the hexadecimal data, and the 7th byte and the 8th byte are data in packet described 16
Start byte in binary data, the 9th byte to the 251st byte are to fill the data field of the hexadecimal data.
In such scheme, due to not being by data length of the individual picture control routine document analysis into hexadecimal data
Fixed, if it exceeds the maximum length of data field is, it is necessary to carry out divided stator frame, so needing 5-6 padding bytes hexadecimals
The total length of data, 7-8 bytes indicate position of the current subpackage in total data bag, facilitate ARM to be re-grouped package.
Step 3：UDP message bag after encapsulation is issued in MIPI modules to be measured by picture signal generator.
Such scheme still further comprises, and the ARM nucleus modules of picture signal generator receive the UDP message, then
