if some one knows how to, for eample make a graph for a vu meter using the propeller video capavility
and display on a monitor, my general idea is tu make something like an hmi, where i can tag outputs and show on a monitor, in the parralax site there is guy that made something similar to what i want, with a motorcycle, he displays engine rev. gasoline level and other stuff.......please i need help with that..

I suggest you look at the graphics object that's included with the Propeller Tool, including its demo program. Start playing with it to see how to produce the background shapes (and colors) that you want. There are calls in that library object to produce lines and arcs. Once you understand how to display the shapes you want, you can make a method (function) that will display a vu meter-like graphic given a value to display.

You are not likely to find anything "ready made" and you will eventually have to learn how to do it yourself.

I am curious if you have found a ready made vu-meter object/code ?

I am at that stage myself and was wondering if someone has already figured out decent graphics with arcs.

Ken Peterson

The Graphics object has a function to draw arcs.

There was also a thread that showed a bot range finding a bottle on table. The monitor screen connected to the bot showed an arc and a distance vector to where the bot thought closeby obstacles were. The bot used a servo adjusted ping sensor. I can't find the thread, maybe someone else remembers...
