XMC1000 and IO00x_ReadPin

[#1]

I have used IO004 App to create INPUT pin (P2.11) and use IO004_ReadPin to read the signal of this pin in main() function.
(I already connected P2.11 to GND with hard wire)

Unfortunately, it's always get value '1' when reading. Anyone got this problem?

The input pin can be negated (e.g. inverted tristate), check the setting for this port.

I did setting this pin to "Tristate", "Pull-Up", "Pull-Down" but still no change.
What I have to do before use ReadPin function??

Actually nothing more. Look in to errata, may be this pin is permanently pull-up (this case has the XMC4500 for example).

Hi iamten,

Port2 is actually the analog port and in order to use this pin as digital input, you have to choose IO001 instead of IO004.

Dave dosen't allowed manual pin assignment of IO004 App to analog pins. At least for XMC4500.

Hi Rou,

I changed to IO001 instead of IO004. It's work!!

Thank you.
