Arrow Watch Pat Hickey, May 2011 Based on 'teatime' by Trammell Hudson. https://bitbucket.org/hudson/watches/ QUICK DEMO VIDEO http://www.youtube.com/watch?v=QXeMZkkN2Qs SUMMARY Shows a simple 3D wireframe rendering of an arrow. The camera rotation matrix is provided over the debug serial port from an InvenSense IMU-3000 sensor board running the Embedded MotionApps (Embedded MPL / "umpl") software. Button presses will cycle through four camera prespectives. The first prespective is updated with data from the serial port, the others are fixed orientations. (This is not useful except to test the drawing code.) I/O is found in umpl_interface.c Arrow verticies and edges are found in arrow.h main_app_loop found in arrowwatch.c BUILDING You'll need the inPulse SDK (http://getinpulse.com). Setup environment variables for your SDK, ARM toolchain, and python installation in the Makefile.rules file.
