Hi All
I am having an issue keeping a pin in high impedance mode.
Currently I have a circuit that looks like this:
A varying voltage alternating between 3.5V to 0V is tied to pins P1.4 (ADC) and P2.4 (Digital IO)
I am trying to keep P2.4 in High Z mode as to not affect my voltage source as my ADC (P1.4) should be monitoring the signal.
Currently, I have P2.4 set as an output with a value of 0, but this seems to keep my signal always low, leading me to believe P2.4 is not in HighZ mode.
Any ideas would be appreciated,
Regards
