bixator Posted December 15, 2016 at 08:34 AM Share Posted December 15, 2016 at 08:34 AM Hi, I would like to use the RS485 Master extension as a Linux serial device (such as /dev/ttyXX) when stacked onto a RED-brick. Is there a (brickd ?) configuration parameter which would allow this ? Thanks. Quote Link to comment Share on other sites More sharing options...
photron Posted December 15, 2016 at 09:08 AM Share Posted December 15, 2016 at 09:08 AM An RS485 Extension is already exposed as /dev/ttyS0, but you cannot use it because brickd is using it. So you either need to disable brickd on the RED Brick or patch brickd to be able to use an RS485 Extension as a normal serial port on the RED Brick.

bixator Posted December 15, 2016 at 09:33 AM Author Share Posted December 15, 2016 at 09:33 AM Hi, Thanks a lot for your quick reply. An RS485 Extension is already exposed as /dev/ttyS0, but you cannot use it because brickd is using it. So, does this /dev/ttyS0 device supports the regular Linux and RS485 specific related ioclt() parameters ? So you either need to disable brickd on the RED Brick or patch brickd to be able to use an RS485 Extension as a normal serial port on the RED Brick. Any tips to patch brickd for this ? Do you plan to add a brickd configuration parameter which would ease this ? Thanks. Quote Link to comment Share on other sites More sharing options...
