This article guide The RS-485 bus is a half-duplex communication bus, so it usually requires an MCU to control the transmit/receive state of the RS-485 transceiver. To save MCU I/O resources, RS-485 automatic transceivers have emerged, but these types of transceivers encounter some application issues to varying degrees. How can these issues be resolved? This … Read more
Summary Have you encountered occasional communication errors while debugging with the CAN or RS-485 bus? Or have you been unable to receive data? Did a bus that had been functioning normally suddenly experience widespread errors or node failures? If you are at a loss for these issues, using bus isolation might easily help you resolve … Read more
Abstract: This design guide discusses several important aspects of the RS-485 standard, aimed at helping engineers design data transmission circuits correctly. 1 Introduction In 1983, the Electronic Industries Association (EIA) approved a new balanced transmission standard known as RS-485. It has been widely praised and applied in industrial, medical, and consumer products, making RS-485 a … Read more
