I was trying to execute but getting error as Description Resource Path Location Type
'LPC_GPIO0' was not declared in this scope LPC11x_Base.cpp /LPC11x_Base/src line 14 C/C++ Problem

#ifdef __USE_CMSIS
#include "LPC11xx.h"
#endif

#include <cr_section_macros.h>

int main(void) {

   //Toggle PIO0_7 in response to the state of PIO3_5
   LPC_SYSCON->SYSAHBCLKCTRL     |= (1<<6);    //enable clock GPIO (sec 3.5.14)
   LPC_IOCON->PIO0_7             &= ~(0x10);   //NOT NECESSARY, turn off pull up (sec 7.4.19)
   LPC_GPIO0->DIR                |= (1<<7);    //set pin direction to output (sec 12.3.2)
   LPC_GPIO3->DIR              &= ~(1<<5);   //set pin 3_5 (pin 21 of QFP) to input

//unsigned int i = 0;

   while(1){       //infinite loop
       if(LPC_GPIO3->DATA & (1<<5))                  //check state of PIO3_5 (sec 12.3.1)
           LPC_GPIO0->DATA           |= (1<<7); //set pin high (sec 12.3.1)
       else
           LPC_GPIO0->DATA           &= ~(1<<7); //set pin low (sec 12.3.1)
       }
   return 0 ;

Hi Sarin cr,

Thank you for your interest in NXP Semiconductor products and
for the opportunity to serve you.
To provide the fastest possible support, I'd hihgly recommend you to refer to the LPCOpen library of LPC11xx series.

Have a great day,
TIC
