| Abstract: | On the basis of brief introduction of the basic charac-ter and the realization method of RS-485 communication, RS-485 communication port is used as the analog input channel andhow to obtain analog by RS-485 communication port is projected associated a short piece of program. After compared with oth-ers, the practical application of this method is discussed in thearticle. |
