I am looking for information on calculating an exponential function for RC servos.
This is a function that is on most RC transmitters, and I would like to incorporate it into my prop projects. I am already able to input servo pulses and then put them back out. What I would like to do is add exponential to the servo pulses before I send it back out. Does anyone know how to calculate this?
Here is a breif explanation of exponential by Hitec.
It is a radio function that will allow you to change the control response of the control sticks from being a linear response to what is known as an increasing response curve, or exponential. An example of how this feature is commonly used would be the pilot on an extremely responsive aerobatic aircraft using full servo throw travel and does not need much servo input to control the plane in level flight but wants to take full advantage of it's aerobatic capabilities. Therefore, exponential is programmed such that very little servo response is provided when the control sticks are near centered, or neutral. As the sticks are moved farther from the neutral point, more servo response is generated at a rate greater than a straight linear response, allowing for quick and precise maneuvers. Exponential values are available from -100% to +100%.
