Hello everyone,

I have been working on a motor control board using the LPC935. I am trying to implement an acceleration/deceleration mode.
Meaning that I set up an acceleration rate via a potentiometer, and the speed changes depending on this rate.
Why I did is that I used an ADC input to get the rate, and I used that rate to increment the "ON duty cycle" of the PWM signal.

I am working with a 8-bit resolution for the PWM, so the minimal value for increasing OCRAL is 1. Thus I need to play with delay to play with the time of variation.

It sounds easy to code, but I am having troubles to make the process stable.

Does anyone have some advices or suggestions about it?

thanks a lot
