variable walking speed ?? (adapting meped software to use 8bit joystick control instead of digital buttons)

[cTurtle98]

does anyone know how to make the walking speed variable?

I am porting the MePed code from https://github.com/ptbw/MePed
to work on an arduino uno with a servoshock http://www.servoshock.com/

currently my plan is to adapt the code by changing the IR remote button signals for servoshock D-pad signals
(I also need to change it to use the servoshock PWM outs)
I would like to be able to use the joysticks instead and have variable walking speed

I have never actually learned how to program in c just kinda figured it out by piecing together arduino example code so we will see how this goes
