I am trying to figure out how to configure PIN 14 to use PWM_OUT_STEPS, 0.9/1000, 0.0, 37 (configuration from April, which we have working). I can’t find any documentation on configuring the IOExpander pins for PWM use, any assistance is appreciated. Thanks
The IO expander PWM doesn’t work like the imp one. It’s not as flexible, and really only intended for LED drive.
See the SX1509 datasheet, linked from the bottom of the page here: http://devwiki.electricimp.com/doku.php?id=hannah
