| Abstract: | This paper,taking the PC as an upper computer,the PXA270 processor as a lower computer,uses RS232 serial port to com- plete the exchange of information. Using MAX3243 it achieves the mutual conversion between TTL logic level and RS 232 level. PC uses C ＋ ＋ to make the serial communication interface, uses DNW tool to test results, visualization and easy operation, so to ensure the accu- racy and reliability of human - computer interaction. |
