USB functional device design process

Before the design, you need to analyze the requirements of the device, including the device type, all functions to be implemented, how each function is implemented, the data transmission type and rate used, and the required hardware resources. Next, we will select a suitable USB interface chip for our functions, compare the performance of various chips, and choose the most cost-effective chip for design. After selecting the chip, you can develop the hardware and software of the actual USB function device. The software development includes the firmware design of the USB chip and the driver of the USB host.ProgramAnd host user interface applications. hardware development involves the implementation of functional device components, hardware interfaces, and resource allocation. The design and debugging of hardware and software are inseparable, finally, the entire software and hardware system is integrated debugging to ensure that the required functions are complete.
