| Abstract: | Through analyzing the principles of multiple master communication based on RS-485 bus, a multiway quiz game system based on RS-485 is suggested along with its hardware schematics and software flowcharts. Testing has shown that the system can be conveniently implemented and it has the merits of easy operation and reliabiltiy as well, which meets the requirements of a multiway quiz game system. |
