Yep, sounds like all the HAL pins & params are set right. Just to make sure, you've added the hm2_5i20.read() and .write() functions to a realtime thread, and you've started the realtime kernel, right? Next I'd want to check the electrical state of the IO pins. With SVST8_4, pwmgen.00 appears on pins 15 (PWM), 19 (Dir), and 23 (Not Enable). Bust out a voltmeter and carefully hook it to pin 23. Then twiddle pwmgen.00.enable high and low and see if the voltage on pin 23 varies as expected (0V when .enable is 1). -- Sebastian Kuzminsky "Much of what we learned from the sense of touch was unscientific prejudice, which must be rejected if we are to have a true picture of the world." -- Bertrand Russell ------------------------------------------------------------------------- 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
