| Abstract: | To solve the problem of the scarcity of RS-422 ports in control system based on dsPIC30F digital signal controller,a method of using on-chip UART modules of the controller to design RS-422/485 port was introduced.Further more,a scheme to de-sign RS-422 ports extend board was introduced.And the details of the scheme was provided. |
