Multiple-function Experimental Board with
Single-chip Microcomputer Interface |
| |
Abstract: | A kind of interface experimental board with MCS-51 single-chipmicrocomputer is designed. All kinds of interface experiments, for example, memory expansion, parallel I/O expansion, serial communication, A/D conversion, D/A conversion,keyboard, LED show, printer and so on, may be done by using it. It makes up for the insufficiency of traditional single functional board. The hardware components and explaination of different interface are given. The flow charts of the practical main program and interface subprogram are listed. |
