can you, program a aurdio to communicate with a rs 458 serial device? Answered

I have a couple of motors, and i want to use them really bad, but i cant figure out how. I can program (some) but I want to know if it is possible, and if so how to communicate with my motors, (they are rs 485 serial motors).

Look into getting a chip like one of these to do the grunt work for you. Interfacing with this chip should be easy, much easier than trying to bitbang RS485.

so how dose this chip work? do you just program it?

The chip itself just interfaces with rs485, through some protocol like SPI or I2C. You need a microcontroller to actually control your motors.
