LPC54628 Writing directly to registers

[aswinprabhu]

Hello,

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;

 while(1){

}

}

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!

Hello Aswin Prabhu ,

Where you get SDK v2.7 ? From I know the latest version now is V2.6.x.

And in which file you find the Macro of IOCON_PIO29 ? If you don't want to use SDK, you need define it 

by yourself.  Recommend you refer to  SDK demo.

And please download SDK package from: https://mcuxpresso.nxp.com/en/select      

Have a great day,
TIC
