| Abstract: | A efficient and simple data acquisition terminal which realizes data communication between the expanded serial communication port and instruments by using a slave single-chip computer as an expanded RS232 series communication port is given in this paper. The hardware and software designs of data acquisition and transfer between two single-chip computers are presented. The measurement and application results show the correctness of this design.The data acquisition terminal is worth spreading . |
