Unable to read GPIO pin value using ReadPortbit and GetPinstate function despite setting Pindirection

[arvindprasad]

I am unable to read the GPIO pin value. I have set the direction correctly, I have even tried setting another GPIO pin HIGH and connecting it to the input GPIO pin, but the readPortbit and GetPinstate function still returns a  zero.#GPIO lpc43sxx #GPIO read

Hi

I am using an LPC 43s67 evaluation board. I fixed the issue

The input buffer is disabled by default. So i enabled it using the scu config.

Thank you
