| Abstract: | How to communicate PC with MCS-51 over short distance is presented. As following, the hard ware circuit diagram which connects PC and MCS-51, the project of software which controls PC and MCS- 51 and the agreement of software are exhibited in ditail. How to select baud rate of asynchronously communication and the error analysis of it are discussed. Furthermore, some aspects of baud rate error and the solution of them can be found. Generally speaking, data processing between PC and MCS-51 can be realized by this technique efficiently and reliably. |
