Design and Realization of Efficient USB Data Transmission System Based on VB

Article Preview

Abstract:

When chip microcomputer and DSP sample much data in some certain environment, it is not possible to transfer the data with high efficient when using the old communication method because they call the top-level function. In this paper, a new communication method with VB and USB is proposed. It calls DLL function to configure and read/write from the hardware directly. With software improved, the method becomes better, the transfer speed can be 11.2Mbps, which is more fast than public 8.1Mbps, so the transfer efficient is improved by 38.3% with this new method.
