Research of serial communication between PC and MCS-51 serial single chip
Liang Zhong-hua · Shenyang Gongye Daxue xuebao · 2005
Presents a serial communication system in order to satisfy the postgraduate need of collecting (data.) The host computer is PC, while the slave computer is single chip computer MCS-51.The paper designs the serial communication protocol ,the hardware and software.There are six commands that can apply all kinds of data exchange in the serial communication protocol. In the hardware, the clock circuit is designed, and the baud rate is configured. In the software, the programs, such as the interruption subroutine, data (exchange) subroutine and the host serial communication subroutine, are designed, compiled and debugged. C language is adopted in the host computer, while the assemble language is used in slave computer. The hardware and software of the system have been successfully debugged and run.
