LPC54628 Writing directly to registers

Question asked by Aswin Prabhu on Sep 26, 2019


I'm trying to write a sample code to drive an LED using the output pin of LPC54628 using uVision 5.28. Saw some examples in SDK 2.7.0 (gpio_led). However, I prefer to write to registers directly instead of using pin_mux files.


#include "LPC54628.h"


int main(void){

IOCON_PIO29 = 0x01;




I tried writing to IOCON register just to see whether the general idea/syntax is ok or not. It throws an error stating 'identifier "IOCON_PIO029" is undefined'.


Can someone tell which files am I missing?

Thanks in advance!
