RS485 Communication Using MAX485 and MSP430 Launchpad

Here we are going to interface a MSP430 Launchpad with a RS485 transceiver chip like MAX485 and communicate with an x86 PC. Serial(TTL) or RS232 protocol is fine if you are planning to communicate over short distances of a few meters,when you increase the range to a few 100 meters RS232 protocol will become inadequate. For long distance wired communication you have to use a different protocol called RS485 which can communicate over a kilometer.”
