Can't manage the accelerometer

[Tiwiz]

Hello everyone I was trying to create an app for my x-fi2, but I can't make it working properly, it just doesn't turn... here I post the code, maybe you know where I'm wrong

h = screen.height()
w = screen.width()
black = color.new(0,0,0)
red = color.new(255,0,0)
screen.fillrect(0,0,w,h,black)
txtsize = text.size(30)
txtcolor = text.color(red)
string = "Hello, World!"
text.draw(0,80,string,"center",w)
screen.update()
text.size(txtsize)
text.color(txtcolor)
screen.update()

--Accendo l'accelerometro
accInit = accelerometer.open();
print(accInit); --Stampo il valore, se è 0 l'accelerometro è acceso
oldDir = accelerometer.getdata("orientation");

while 1 do
	--controllo la posizione dell'accelerometro
	dir = accelerometer.getdata("orientation");
	if dir ~= oldDir then
		if dir == 1 then
			screen.orientation(0);
		elseif dir == 2 then
			screen.orientation(1);
		elseif dir == 3 then
			screen.orientation(0);
		elseif dir == 4 then
			screen.orientation(1);
		end
		
		oldDir = dir;
		green = color.new(124,252,0)
		txtsize = text.size(30)
		txtcolor = text.color(green)
		text.draw(0,80,string,"center",w)
		screen.update()
		text.size(txtsize)
		text.color(txtcolor)
		screen.update()
	end
	if control.read()==1 then
		if control.isButton()==1 then
			if button.click()==1 then
				if accInit==0 then
					accelerometer.close();
				end
				break
			end
		elseif control.isTouch()==1 then
			if accInit==0 then
				accelerometer.close();
			end
			break
		end
	else
		os.sleep(10)
	end
	
end

it's almost all copied from the tutorial, but it doesn't turn...either it doesn't become green...where I'm doing it wrong?

You forgot to set the datatype for the accelerometer output after you've opened it:

accInit = accelerometer.open();
os.sleep(10);
accelerometer.set_datatype("orientation")

It's still not working as it should I think, but at least the text turns green and the screen changes orientation in some way... I believe the accelerometer is known to output wrong orientation numbers.. maybe you should just use the x,y,z for orientation.

By the way have you seen Tetrajak's accelerometer output app? Helped me a lot to figure out how the accelometer functions.

oh, thank you very much, I didn't find anything! I'll look at it and correct mine, thank you!
