Unable to read GPIO pins.

[vxs187]

I am not understanding how to read GPIO pins using the LPC 4370, I am unable to get the right reading. I am trying to give a DC supply but am not able to get any proper output, it always gives me 0, meaning the input is always low, even when I am giving a DC of 3.3V. Do I have to supply a greater voltage? I am totally left clueless. I am using GPIO1_0.

Hi,

I suggest to use the LPCOpen Blinky example, the blinky example flashes an LED in a periodic rate. 

You can download LPCOpem from the following link:

LPCOpen Software for LPC43XX|NXP 

Have a great day,
Sol
