You can use the i2c-test program: <http://docswiki.gumstix.com/index.php/Robostix_i2c_test> The SCL and SDA would change, but it would be pretty quick (7 bits @ 100 kHz on SCL and a couple transitions on SDA). I'd recommend doing a single shot trigger on SCL, with your timebase set so that your scope image is about 100 microseconds wide (about 10 microseconds per divison?) -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |
