I’m looking to experiment with a motorised blade plug, utilising a step down regulator inside the plug to power a 3.0V motor off of the 3.7V neopixel blade connector.
The motor will spin fine while the blade is on, but my issue is that when my neopixel blade is completely turned off, the power from the fets still flows with no neopixels active, so the motor that’s running off the neopixel power will still spin. You could argue, set the IDLE_OFF_TIME to a very short number and cut power to ALL Fets (which on its own, does cut power to the motor like I’m looking for), but I have chassis neopixels I want to keep going.
Is it possible to create an"IDLE_OFF_TIME" function that is specific to certain FET pins? Or if not, I’m willing to try other options.
(Before anyone asks, I cant use blade ID to define the motor plug any differently, the plug still has neopixels in it anyway. and I can’t use any secondary data lines because I’m using a 10 pole chassis connector and every slot is filled. This must be done within the confines of 3.7v and a positive, negative and neopixel data.)
