I'm trying to work out an algorithm to calculate a set of points along an acceleration/deceleration curve. The curve itself I suppose could be your average exponential curve up to a set point after which speed is constant. My problem is the algorithm to let me work out the points along the line so I can work out the values I'll need to feed into the program that sets the acceleration at those points. In the end it'll be about 20 points along a 2 second curve, with the Y-axis of the curve being time and the X-axis being a value between 0 and 128. I don't know if I'm explaining this particularly clearly... what I intend to use it for is setting the duty cycle period of a PWM (Pulse Width Modulation) signal to control the speed of a motor in a project I'm working on now. I'll be using an Arduino (google it if you don't know what it is. They're really cool) to control the motor, but I need to feed it the points of the curve.
