These days in the research on data acquisition program, but the communication of upper machine and lower machine, the principle of not too clear,,,
Data from the machine's interface by driving transmission (upload and download) to the upper machine (PC) memory, PC application to how to do to achieve this function?
The content of the need to use what aspects?
Ask everybody to give directions,,,
(PS: the new environment, no one take, had to yourself to learn, I hope you to guide the)

This depends on what's driving, common way of communication is via a serial port (including USB analog serial port), GPIB, network communication, this interface does not need special drive, and is more concerned and lower machine communication protocols,As PC is commonly initiate data request, send a frame command a machine down, under a machine to return to a frame of data in this way, if the machine to provide driver, it should be more simple, directly by the drive to provide the API to send and receive, and read and write files makes no difference,

With the landlord to ask, I also doing multichannel parallel data acquisition project, related books, tutorials can you recommend? Montana thank you
