| Abstract: | This paper introduces the design and implement of multi-protocol serial communication module based on VXI Bus. This design makes use of the chip-- SC28C94 which is a Quad universal asynchronous receiver/transmitter made by Philips, combining large scale FPGA device and the corresponding control program. The communication protocol can be selected between RS422/485 and RS232 by software, while the hardware do not need any change. So one module can implement 16 RS232 protocol communication or 8 RS422 /485 protocol communication. |
