Hello, I have came across this RS-485 tutorial, but I am farily new to this and I need some clarifications.
I am currently running the latest Debian image on my beaglebone black >> Linux beaglebone 3.8.13-bone70 #1 SMP Fri Jan 23 02:15:42 UTC 2015 armv7l >> GNU/Linux > > > On the logic supply website, > > Let's dive into the Kernel a bit to to see how RS-485 works in Linux; the > standard steps to put a UART into RS-485 mode are: > > 1. Open the special tty file > 2. Create a serial_rs485 struct and set the desired configuration > values > 3. Pass the configured struct to Kernel driver by using ioctl > <http://man7.org/linux/man-pages/man2/ioctl.2.html> on the open serial > port file descripto > > Website: http://inspire.logicsupply.com/2014/09/beaglebone-rs-485-communication.html I am kinda lost on where to find this special tty file (is it from some .dts file?), and where to put the serial_rs485 struct. Can someone guide me through this process on how to do this?
