Sebastian is probably the one to ask, but, did you have the driver enable the PWM0? Not the HAL enable but the driver PWM generator count If the PWM pin is still an input (ground with a 300 ohm or so resistor to test), then the drive did not enable the GPIO pin as a PWM output > > Thanks, > Eric > > > ------------------------------------------------------------------------- > 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=/ > _______________________________________________ > Emc-users mailing list > Emc-users@lists.sourceforge.net > https://lists.sourceforge.net/lists/listinfo/emc-users > Peter Wallace Mesa Electronics (\__/) (='.'=) This is Bunny.
