hello world on easyweb

Development Boards MicroMod

hi there,

i just wrote my first “hello world” programm on easyweb II using the icc430 application builder.

it shall turn on the status-led when pressing B1 and switch the relais 1 when pressing B2.

there is only one problem:

when pressing no button, the status-led blinks and when pressing B1 it is permanently on an the relais is switched. when pressing B2 nothing happens.

so :slight_smile: it says “hello world” but its more like “heloh werld” :slight_smile:

can you tell me, what i made wrong?

here is my code

//ICC-MSP application builder [F149] : 25.11.2003 22:55:46
//Target 14x device

#include <msp430x14x.h>
#include <msp430def.h>

void clock_init()
{
  //DCO=0x00
 DCOCTL=0x00;
 BCSCTL2=0x00;
 BCSCTL1=0x00;
}

void port_init()
{
 //P1OUT=0x00;
 P1DIR=0x60;
 P1IES=0x00;
 P1IE=0x00;
 P1SEL=0x00;
 P2OUT=0x00;
 P2DIR=0x02;
 P2IES=0x00;
 P2IE=0x00;
 P2SEL=0x00;
 P3OUT=0x00;
 P3DIR=0xF0;
 P3SEL=0x00;
 P4OUT=0x00;
 P4DIR=0x0F;
 P4SEL=0x00;
 P5OUT=0x00;
 P5DIR=0x00;
 P5SEL=0x00;
 P6OUT=0x00;
 P6DIR=0x00;
 P6SEL=0x00;
}

//call this routine to initialise all peripherals
void init_devices(void)
{
 //stop errant interrupts until set up
 DINT(); //disable all interrupts
 ME1=0X00; //disable sfr peripherals
 ME2=0X00; 
 IE1=0x00; //disable sfr interrupts
 IE2=0x00; 
 //watchdog initialisation including nmi function
 WDTCTL=0x5A00 | 0x00;
 //initialise other peripherals
 clock_init();
 port_init();

 ME1=0x00;
 ME2=0x00;
 IE1=0x00;
 IE2=0x00;
 EINT(); //re-enable interrupts
}

//interrupt handlers 

void main(void){
//clock_init();
port_init();
init_devices();
while(1){P2OUT=0x00;
		P1OUT=0x00;
		while (P4IN & 0x10) {P2OUT=0x02;}
		while (P4IN & 0x20) {P1OUT=0x20;} 
		 }
}

thanks a lot

xray
