Abstract:With the development of Surface Mounting Technology, the size of chips on the PCB are becoming smaller and smaller, more and more chips are mounted on the PCB, which have made the tests for PCBs and chips more difficult. A USB testing system is a testing tool for USB terminal on the main board of a digital camera, which can take the place of actual computer by building up a USB host. Single chip microcomputer AT89C52 and USB chip CH375 can build up such a USB host to meet the requirement of mass production ...
Keywords:USB (university serial bus)  host  USB testing  single chip microcomputer
