True, providing the carrier frequency and modulation are both being generated in software. That approach will give you the widest range of compatibility, providing your software can keep up, but also the highest CPU load. If you know the carrier frequency your device uses (typically 40 to 80 KHz), you might be better off finding a commercial IR blaster that included the appropriate hardware to generate that, so the computer only need to supply the data signal to modulate the carrier. Your best bet at figuring out what is going on is to get an IR phototransistor and hook it up to an oscilloscope (that you can perhaps borrow from a friend). Then compare the signal from the original remote to the one produced by the IR blaster. -Tom ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ Mvpmc-users mailing list [email protected] https://lists.sourceforge.net/lists/listinfo/mvpmc-users mvpmc wiki: http://mvpmc.wikispaces.com/
