The scripts were originally written to read data from the Arduino uart port and I want to read from the usb port instead so I will need to do some hacking. First step after installing lua was to get libusb installed. I chose to use libusb-1.0.19 from http://sourceforge.net/projects/libusb/files/latest/ which compiled ok from a tar.gz file. Then I did cp /home/pi/libusb-1.0.19/libusb/.libs/libusb-1.0.so libusb.so and then sudo cp /home/pi/libusb-1.0.19/libusb.so /usr/local/lib/lua/5.1/ At this point I get an error when I run lua Lua 5.1.5 Copyright (C) 1994-2012 Lua.org, PUC-Rio > require('libusb') error loading module 'libusb' from file './libusb.so': ./libusb.so: undefined symbol: luaopen_libusb stack traceback: [C]: ? [C]: in function 'require' stdin:1: in main chunk [C]: ? Can anyone offer some advice on where I go from here?
