pxa255中的RS485支持 [英] RS485 support in pxa255

问题描述

我想使用放置在卡上的rs485.我正在使用arma Linux和pxa255处理器.我已经检查了位于arm-linux工具链中的"serial.h"，但不幸的是，尽管在cris等其他环境中也支持该RS485设置结构，但我找不到合适的rs485设置结构.所以现在，我是否必须编写一个低级驱动程序来启用rs485或还有其他更简单的方法来做到这一点?

I want to use rs485 placed on my card. I'm working on arm-linux and with pxa255 processor. I have already checked "serial.h" located in arm-linux tool chain but unfortunately i couldn't find the appropriate rs485 settings struct although it is supported in some other environments like cris. So now, do i have to write a low-level driver to enable rs485 or is there any other easier way to do this?
