Research and development in MIPI modules, produce, test and dispatch from the factory before in debugging link, it is necessary to be determined by way of a screen
The module whether normal work.Implement point screen operation and several results occur：
First, module is successfully lighted, and picture is normal；
2nd, module is successfully lighted, but picture is abnormal；
3rd, module point does not work.
Appearance point screen unsuccessful outcome can explain wherein reason, non-developer such as tester, visitor except developer
Family is often confused, without other ancillary methods in addition to by virtue of experience and to research and development seeking help, extreme influence test and production
Efficiency, and occur mistake every time and be required to technical staff being handled, waste of manpower.
Therefore need to invent error condition detection and the method handled during a kind of MIPI modules point screen, strengthen user's body
Test, improve test and production efficiency.
The content of the invention
In order to solve the above technical problems, can be in MIPI module screen tests to error condition the invention provides one kind
Detected, and carry out adaptive error handling method in the MIPI module screen tests of self-adaptive processing.
The technical scheme is that：Adaptive error handling method in a kind of MIPI modules screen test, it is included such as
Lower step：
Step 1：Host computer transmits upper strata BMP view data and MIPI to be measured to BMP images and parameter acquiring processing module
Liquid crystal module configuration parameter, three-primary-color image is extracted according to MIPI liquid crystal modules configuration parameter to be measured from BMP view data
Data, and synchronizing signal corresponding with local three primary colors data is produced, when host computer startup MIPI liquid crystal modules spread its tail operation,
Spread its tail instruction, three-primary-color image data and corresponding synchronizing signal of startup is conveyed to by BMP images and parameter acquiring processing module
MIPI is spread its tail instruction sending module；
Step 2：MIPI instruction sending modules of spreading its tail are opened receiving the startup that BMP images and parameter acquiring processing module send
After screen instruction, MIPI signal transmitting modules are turned by view data according to MIPI consensus standards and sent to MIPI liquid crystal modules to be measured
