Stepper Complex Motion Profile

hi,

trying implement not usual motion profile stepper motor controlled driver takes step/dir signals. want following:

1. accelerate speed a
2. rotate @ constant speed specified amount of revolutions.
3. accelerate speed b
4. rotate @ constant speed b specified amount of revolutions.
5. decelerate speed a.
6. start over.

was trying implement accelstepper library, doesn't accel/decel 1 speed , can't seem find way round this.

would appreciate if has idea this.

thanks,
dan

it not difficult control stepper without accelstepper. see examples in simple stepper code - second one.

starting point should not difficult create own acceleration function. case of reducing value of variable millisbetweensteps according acceleration system.
