為了提高單片機(jī)與計(jì)算機(jī)之間的數(shù)據(jù)傳輸速度，設(shè)計(jì)了基于CH372芯片的USB通信技術(shù)來實(shí)現(xiàn)單片機(jī)與計(jì)算機(jī)之間的數(shù)據(jù)通信。采用CH372芯片與單片機(jī)AT89C52配合的方法設(shè)計(jì)了單片機(jī)端的硬件電路，開發(fā)了CH372芯片基于匯編語言平臺(tái)的單片機(jī)端的數(shù)據(jù)收發(fā)程序和基于Visual Basic語言平臺(tái)的計(jì)算機(jī)端的命令、數(shù)據(jù)收發(fā)程序。試驗(yàn)結(jié)果表明，該系統(tǒng)設(shè)計(jì)能夠很好地實(shí)現(xiàn)單片機(jī)與計(jì)算機(jī)之間的數(shù)據(jù)傳輸。

Abstract:

?In order to improve the data transmitting speed between computer and singlechip, the paper designed a USB communication technique to achieve data transwitting between computer and singlechip by using CH372 chip. CH372 chip and AT89C52 singlechip were adopt in the design of the singlechips hardware. The data sending and receiving procedure of single chip based on assemble language, and the command and data sending and receiving procedure of computer based on Visual Basic language were explored independently. Finally, the result of the experiment proves that the design in the paper can carry out the data communication between the computer and singnlechip
