ir help!!!

I have made a simple program that is supposed to track the ir position of the wiimote, but i only get y positions, the x positions i get are 0 or 1.401298e-45.
here is the code

#include 
#include 
#include 
#include 
#include 
#include 
#include 
#include 

static u32 *xfb;
static GXRModeObj *rmode;


ir_t ir;


void Initialise() {

	VIDEO_Init();
	WPAD_Init();

	rmode = VIDEO_GetPreferredMode(NULL);

	xfb = MEM_K0_TO_K1(SYS_AllocateFramebuffer(rmode));
	console_init(xfb,20,20,rmode->fbWidth,rmode->xfbHeight,rmode->fbWidth*VI_DISPLAY_PIX_SZ);

	VIDEO_Configure(rmode);
	VIDEO_SetNextFramebuffer(xfb);
	VIDEO_SetBlack(FALSE);
	VIDEO_Flush();
	VIDEO_WaitVSync();
	if(rmode->viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();
}

int main() {

	Initialise();

	while(1) {

		WPAD_ScanPads();
		WPAD_IR(0, &ir);
		WPAD_SetDataFormat(0, WPAD_FMT_BTNS_ACC_IR);
		WPAD_SetVRes(0, 640, 480);

		
		u32 buttonsDown = WPAD_ButtonsDown(0);

		if( buttonsDown & WPAD_BUTTON_B ) {
			//Prints wiimote position
			printf("X= %e Y= %e\n", ir.x, ir.y);
		}	
		
		//Exit
		if (buttonsDown & WPAD_BUTTON_HOME) {
			exit(0);
		}
	}

	return 0;
}

You should be printing a double/float.

printf("X= %f Y= %f\n", ir.x, ir.y);

Also you can move the below code under WPAD_Init();

WPAD_SetDataFormat(0, WPAD_FMT_BTNS_ACC_IR);
WPAD_SetVRes(0, 640, 480);

yeah %e is for double values. ir.x/y is a float. Try a %f in the printf.

thanks but still when i put %f it gives me 0 ALLWAYS for the x value and i get a range of Y's, is this a hardware issue, i dont think so because it works normally and on other apps, like the homebrew browser.

Have you tried putting the PAD init stuff outside the loop. They really only need to be called once. See Below :-

int main() {

	Initialise();

	WPAD_SetDataFormat(0, WPAD_FMT_BTNS_ACC_IR);
	WPAD_SetVRes(0, 640, 480);

	while(1) {

		WPAD_ScanPads();
		WPAD_IR(0, &ir);
		
		u32 buttonsDown = WPAD_ButtonsDown(0);

		if( buttonsDown & WPAD_BUTTON_B ) {
			//Prints wiimote position
			printf("X= %f Y= %f\n", ir.x, ir.y);
		}	
		
		//Exit
		if (buttonsDown & WPAD_BUTTON_HOME) {
			exit(0);
		}
	}

	return 0;
}

ya it's outside now but i still get the same problem, also it gives me a screen with a code dump on it, how can i fix this?

is iit possible that sombody could make a program that works for the pointer(it can be as simple as printing x and y values) and test it to make sure it works and then post it?

make x and y into variables prior to the print f

int main() {

Initialise();

WPAD_SetDataFormat(0, WPAD_FMT_BTNS_ACC_IR);
WPAD_SetVRes(0, 640, 480);

while(1) {

WPAD_ScanPads();
WPAD_IR(0, &ir);
int cursorx, cursory
cursorx =ir.x
cursory =ir.y


u32 buttonsDown = WPAD_ButtonsDown(0);

if( buttonsDown & WPAD_BUTTON_B ) {
//Prints wiimote position
printf("X= %i Y= %i\n", cursorx, cursory);
}

//Exit
if (buttonsDown & WPAD_BUTTON_HOME) {
exit(0);
}
}

return 0;
}




This is the code i used and it worked for me.

I still didn't get any X values, and there is opening brackets around my #include's

here is my source
#include stdio.h>
#include stdlib.h>
#include string.h>
#include malloc.h>
#include ogcsys.h>
#include gccore.h>
#include wiiuse/wpad.h>

static u32 *xfb;
static GXRModeObj *rmode;


ir_t ir;


void Initialise() {

	VIDEO_Init();
	WPAD_Init();

	rmode = VIDEO_GetPreferredMode(NULL);

	xfb = MEM_K0_TO_K1(SYS_AllocateFramebuffer(rmode));
	console_init(xfb,20,20,rmode->fbWidth,rmode->xfbHeight,rmode->fbWidth*VI_DISPLAY_PIX_SZ);

	VIDEO_Configure(rmode);
	VIDEO_SetNextFramebuffer(xfb);
	VIDEO_SetBlack(FALSE);
	VIDEO_Flush();
	VIDEO_WaitVSync();
	if(rmode->viTVMode&VI_NON_INTERLACE) VIDEO_WaitVSync();
}


int main() {

	Initialise();

	WPAD_SetDataFormat(0, WPAD_FMT_BTNS_ACC_IR);
	WPAD_SetVRes(0, 640, 480);

	while(1) {

		WPAD_ScanPads();
		WPAD_IR(0, &ir);
		
		u32 buttonsDown = WPAD_ButtonsDown(0);

		if( buttonsDown & WPAD_BUTTON_B ) {
			//Prints wiimote position
			printf("X= %f Y= %f\n", ir.x, ir.y);
		}	
		
		//Exit
		if (buttonsDown & WPAD_BUTTON_HOME) {
			exit(0);
		}
	}

	return 0;
}

I tried compiling your code and it works for me.
Try running my compilation [agoajm.googlepages.com] and see if it works.
If it does then your problem is with your devkit installation.

thx, i reinstalled it and it works
