RE: Graphics Analog Gauge

schwiegjc

Is there any graphics code that can display a sensor data (pitch, roll, etc.) to a graphics analog gauge ether on a TV or VGA monitor? I have built a simple analog gauge that displayed heading variable but looks every rudimentary.

tv : "tv"
gr : "graphics"

gr.color(2)
gr.width(0)
gr.arc(0, -50, 50, 50, 0, 409, 40, 3)
gr.arc(0, -50, 45, 45, 204, 409, 40, 3)
gr.color(0)
gr.width(2)
gr.arc(0, -50, 42, 42, 0, 204, 40, 3)
gr.arc(0, -50, 42, 42, 0, 204, 40, 3)
gr.color(1)
gr.width(0)
gr.arc(0, -50, 40, 40, (4096-(((heading/10)+90)*4096)/180) ,1, 1, 3)
gr.arc(0, -50, 40, 40, (4096-(((heading/10))*4096)/180) ,1, 1, 3)
gr.arc(0, -50, 40, 40, (4096-(((heading/10)+180)*4096)/180) ,1, 1, 3)

I recall someone had done some work in this area and perhaps had created some objects. Unfortunately, I don't remember who it was, and I don't know if it's on OBEX.

I think there are some interesting methods for you.

The following link does seem to work. Is there another away of seeing the link?

That worked great. The video overlay seems to be interesting. The overlay generator capability is from Terry Hitts Propeller OSD. How do I find that?

schwiegjc

I think that the two options should be very helpful.
Brian,
Where do you find the widgets.spin code? It seems to be referenced in the graphicswidgets_demo code.

Overlaying the video with the propellar graphics icons would be perfect. The graphics alone do not standout enough on a LCD screen.
