I am writing my own TinyG interface and have a question on how to implement a continuous move while a key is down.
On the ShopBot, they have a feature that will move in any XYZ direction as long as a key is down and stop when the key is liefted. So, you can move in the down in the Y direction by pressing and holing down the down arrow. When you lift up, the movement stops. This is useful in calibrating things. I intend to use this to position my CNC head at a user selected location.
Any advice on how to implement this feature?
