I added two new examples to the library: pruss_add and pruss_toggle. Find details in the documentation <http://users.freebasic-portal.de/tjf/Projekte/libpruio/doc/html/ChaExamples.html>. The example pruss_toggle is close to your bitbanging target. it configures a PRU-GPIO output, toggles that pin and measures the pulse train by libpruio CAP feature. (Reduced toggling speed in order to get good measurements.) Note: single source! All code in one file (pinmuxing, firmware, PRUSS control), running at user space (no administrator privileges necessary). -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
