For best viewing of the Northern Lights installation and testing, download an RTSP-compatible client (e.g., VLC at http://www.videolan.org) and connect to rtsp:spare1-29.cs.purdue.edu/mpeg4/media.amp. ====== Collected (but Rough) Documentation ====== * Block diagram (Mike Miller, 3/3/08). * Frame to boards (Mike Miller, 3/3/08). ====== Expedient for Testing/Running the Northern Lights====== Northern Lights information from Zach Tatlock, 1/12/08… I'm attaching a hacked way to drive the boards from the current new NL. It is ugly, but uses the same mechanism as the old NL, so will work modulo changes that Mike has made to hardware. As I left things, all you should need to do (to run to old development board) is attach the parallel port to a PC and then: $ cd hack_nl/ $ vim Main.java # change the size of Pat.SIZE to the # of transformers $ make $ ./gen_c_driver trial.nl $ sudo ./C_DRIVER/drive Note that you might have to find the correct “io.h” to include (in C_DRIVER/HEADER). On my Ubuntu system, it's “sys/io.h”. On my old Slackware box it's “asm/io.h”.
