Re: Active low transmitter question
anyone else have any thoughts on this?
using a resistor to drive a pin to a default logic level is not an uncommon practice.
so common that i would not be surprised that your [type not disclosed ] transmitter has such a pullup
resistor already installed. the only reason i could see for an additional pullup would be if the pic was routinely disconnected
from a device that did not have a built in pullup or that an open drain/collector pic pin was in use.
summing up with the detail[almost non existent] you have provided it seems to be a pointless waste of a component
that could easily be eliminated with good programming practice.
