I am trying to get an old RCX working with leJOS. I already have it working with NQC and BricxCC.
While NCQ/BricxCC seems to recognize my usb-to-serial (which appears as "COM5" to the OS), the leJOS I downloaded does not. I believe that it uses Java rxtx on Windows to access the serial port.
There seems to be a number of pieces I will need to get into place to make it work.
I am running Windows 7 professional Version 6.1 (Build 7601:Service Pack 1) on my work laptop (I have OS X on the desktop at home - I suppose I could boot to Linux from a USB or CD on my work machine if I really needed to.)
If I stick with Windows 7 I will need a version of the RXTX DLL which works with:
- this version of Windows
- my COM5 port (which is really usb-to-serial).
I also need a version of Java which works with the leJOS java source code, (found some references that not all JVM versions work) and that version of RXTX/DLL and the RCX (not the NXT...I don't own one).
Alternatively I figure I can upload the leJOS firmware with NQC, but after an hour of trying different searches on the internet I can not find the location/name of the firmware file, or build instructions.
The leJOS forum looks like no-one has posted to the RCX section since 2014, so I thought I might try here.
I'd prefer a Windows 7 solution (as that is where BricxCC and NCQ live now), but I would be willing to consider alternatives if no Windows 7 solution exists.
