The meter I have now doesn't have a working current function; this prompted me figure out the method I'm using presently. > I notice that you don't CLRF GPIO - don't know whether that > has any bearing. I don't. The only input is GP3, it is grounded (I saw your other post about this pin.) I'm just hand-waving tho, see: http://roland.sw.edu/matthew/blinker.png Still, I'm wondering why a 16kHz clocked chip and one clocked at 4MHz, running firmware that does the same thing, have current usages that are so similar. The current use in test 1 still seems awfully high.
