Re: Harmony 3, PIC32MZ power-saving?
Unofficial but maybe worth a try:
a) Measure power in simple project that doesn't enable anything that won't be used in powerdown, this is your 'target sleep' power consumption.
b) Measure power in full operation, this is target 'run power'
c) Compare to power in real app when you enter powerdown, did you reach 'target sleep'?
d) when you power back up check if power returns to 'target run', if not maybe something not completely functional.
e) (Careful to appropriately set pullups/pulldowns for items that aren't in use such that those don't draw unnecessary current, won't provide paths that may partially power unused circuits, but will provide appropriate signals where needed though those maybe can be overridden in code for less power).
