The product includes multiple development elements, mechanical design, electronics hardware and firmware design, software application on the PC side and scientific aspects in thermal conductivity test. In our research we provide a way to expand the Universal Serial Bus (USB) interface function for TCi inside which the microprocessor has no USB module. Various approaches are considered including: Device firmware, USB firmware, USB driver ( windows OS side) and Device application software. To be specific, what is discussed and described in this thesis is a whole process about how to develop a USB support product which means our solution can be applied to many products rather than just the TCi.text/xmlx, 89 pageselectronicen-CAhttp://purl.org/coar/access_right/c_abf2master thesis2023-03-01Bremner, DavidKent, KennethComputer Science
