neo nav
Offline

Hi,

I am using LPC1114.

In this, Port0.4 & Port0.5 are multiplexed gpio & i2c pins.

These pins are not acting well,even though I configured them as GPIO pins only...

Please help me out........

    Note that this has nothing to do with Keil: it is a matter of correctly configuring the chip hardware; for which, again, you need to study the chip manufacturer's documentation - in this case, NXP.

    Have you looked at the examples that NXP provide for their chips?

    ics.nxp.com/.../ - note that NXP have forums specifically for their products.
