In NXT-G, there was a "Legacy" Block pack which had blocks to allow for the use of RCX motors/sensors with the NXT, as long as you had a converter cable. However, the EV3 software does not have this, and it currently does not appear to have support for converter cables due to the lack of special programming blocks you can download.
What I basically need to do is connect two touch sensors to the same port, so that the EV3 brick would get input if either one is pressed. I have a pair each of RCX, NXT and EV3 touch sensors. I also have three of the NXT-RCX converter wires. Unfortunately, none of the sensors are working with the converter cables, and I cannot use this or this method because I'm preparing for a competition which doesn't allow modification of lego parts.
I came across this thread from the lego site from 2013 regarding this issue, but it offers no solution. I've even tried using the raw sensor blocks with the touch sensors, but they don't give me any output.
I am also only allowed to use the EV3-G programming interface.
Does anyone know how I can use these split cables with the EV3 brick?
