== Welcome to OpenHD!
OpenHD uses off-the-shelf Wi-Fi adapters available for purchase online. However, it is not standard Wi-Fi, which is unsuitable for low-latency
or very long-distance transmission. Instead, OpenHD configures the Wi-Fi adapter in a way that is closer to a simple broadcast, much like analog
video transmission hardware you may be using already.
High-definition video, 2-way UAV telemetry, audio, and RC control signals can all be sent over a single transmission channel.
A multi-platform Open.HD app is available for live video with a customizable OSD.
TIP: Look around, read the {wiki}, ask questions on {telegram} and contribute back!

Package openvg is a wrapper to a C library of high-level 2D graphics operations built on OpenVG 1.1 The typical "hello world" program looks like this: package main import ( "bufio" "github.com/ajstarks/openvg" "os" ) func main() { width, height := openvg.Init() // OpenGL, etc initialization w2 := openvg.VGfloat(width / 2) h2 := openvg.VGfloat(height / 2) w := openvg.VGfloat(width) openvg.Start(width, height) // Start the picture openvg.BackgroundColor("black") // Black background openvg.FillRGB(44, 100, 232, 1) // Big blue marble openvg.Circle(w2, 0, w) // The "world" openvg.FillColor("rgb(100,255,123)") // White text openvg.TextMid(w2, h2, "hello, world", "serif", width/10) // Greetings openvg.End() // End the picture bufio.NewReader(os.Stdin).ReadBytes('\n') // Pause until [RETURN] openvg.Finish() // Graphics cleanup } Functions The Init function provides the necessary graphics subsystem initialization and the dimensions of the whole canvas.
