Hello,
This is a rather silly question, but when driving IO pins such as XSMT, FLT, DEMP, and FMT is it required that I place a resistor between the pin and the GND / +3.3v? I've assembled a test board and it's not functional, so I'm trying to rule out the fact that I have my pins driven directly from 3.3v/GND as the culprit.
Thanks,
-Ted
