Re: Weatherproof Flexistrips Flickering with PWM
Okay. After much experimentation, we have made a few more determinations. This does not appear to have anything to do with the strips themselves, but rather an issue with PWM on the Arduino. Specifically, on the lower port.
If we move the RGB pins up to 9,10,11... everything works fine. If we use any combination that includes two pins on the lower port, the flickering occurs. Using any combination with only one pin on the lower port works fine.
I still have no idea what's really going on, but this does appear to be an Arduino issue, not an issue with the strips. However, if anyone has any ideas on this, they would be very welcome. The installation was supposed to use two independent strips, so we still need all six PWM pins. We have successfully tested this on a Mega, and it works fine with any combination of pins. However, I would hate to have to waste a mega for such a simple project.
