| Abstract: | A series of questions during the designing are discussed in this paper.Following these questions,the core design of C8051F SOC MCUs and CP2102,a new USB to UART bridge is introduced.The design successfully solves the main issues,such as the confliction in MCU and the data collision in bus.It improves the stability and real-time performances of the system and makes the system suitable for various long-distance real-time surveillance networks. |
