| Abstract: | Signals of A/D card( AC1210) are acquired by extended function of built-in assembler in Delphi in the mode of query and timer. Core programming languages and flow charts are introduced. Further more, a DLL sampling program of C language is transferred by Delphi to acquire signals in the DMA mode. A interface of data acquisition and graphics process is also realized. An example of two Sine waves acquired in the DMA mode is checked. |
