Development Of Virtual Oscilloscope Based On Android Platform

Oscilloscope is a basic test instrument. Not only used in industry test, butalso used electronic test. There are still some technical in the production ofoscilloscope with foreign country at present. And due to move terminal developrapid, Android also have the most user. At this setting, develop oscilloscopebased on Android is import and will have vast market. The instrument of test andanalysis becom more and more intelligentize, digitizing, automate, all of thesecould not isolate from the rapid development of Android platform. Except trendof the above, these size becom more and more small, and weight more and morelight. And all of thse don’t resist they pursue the better function.With the chanceof off-side work and equipment maintenance growing, to make the test moreconvenient. The development of digital of virtual oscilloscope,based moveplatform strive to develop convenence of data analysis is a trend.Direct at the trend of taday’s instrument of test, this thesis research virtualoscilloscope based Android platform. The basic function of virtual oscilloscope isthe main content of our research. Such as, design framwork of systementirely, the advantage of this design is coud keep agreed with Android; Use USBHost provide by Android to complete data transfer of system; This constructioncan control transfer; The fashion to realize data store，select SD card store data.The advantage of this way is bring convinence, prefer to requre bring convinenceof system; Design of UI, use Linearlayout and Relativelayout, use theSurfaceView、Button and so on; Through the JNI to realize the function offiltering. The advantage of this meaning is can direct invoking means of bottom,have good working efficiency, and could improve reuing of code.
