Getting started with Blinky

Ashley Madison

Hi, there,

I am new to ARM and just downloaded MDK3.70 demo to try to get Blinky to run on lpc2106.

I set up uvision3, and wired up the schematic in Proteus (7.1), since I already downloaded an almost identical program there - with a .hex file. the program is to flash LEDs linked to P0.0-P0.7. The Proteus simulation, with the pre-made .hex file, worked well.

so I decided to produce my own .hex file in uvision3, see below.

=========code===========
#include <LPC210x.H> /* LPC210x definitions */

void wait (void) { /* wait function */ ; /* only to delay for LED flashes */
}

int main (void) {
// unsigned int i; /* Delay var */
// unsigned int j; /* LED var */

PINSEL0=0x00; IODIR = 0xFF; // P0.0..7 defined as Outputs */

while (1) { IOSET=0xff; //?? IOCLR=0xff; }
}

========end of code==============

I didn't put the wait() function there for simplicity.

well, uvision did produce a .hex file. I loaded the file to the proteus simulation, and replaced the pre-made .hex. no go. all ports are in high impedance mode and nothing happened.

I would appreciate very much if you can point me in the right direction. I am thinking the problem is likely caused by my uvision not producing the right .hex file (wrong settings somewhere?) but I am not sure where to start.

your help is greatly appreciated. Thanks.

    sorry for the messy posting.

    I am learning the "pre" tag, :)

    #include <LPC210x.H>                       /* LPC210x definitions */

void wait(void)
{
        int  i,dly;
        for (dly=10;dly>0;dly--)
                for(i=0;i<50000;i++);
}
/****************************************************************
*??: main()
*??: ??LED?
****************************************************************/
int main(void)
{
        PINSEL0=0x00;      //??????GPIO
        IODIR= 0xff;      //?????
        while(1){
                IOSET=0xff;     //??
                wait();
                IOCLR=0xff;
        }
}
