where are header files?

Hello,
New to Sparki and the provided examples with sparki.motorRotate(MOTOR_LEFT, DIR_CW, 50), for example, don’t work anymore. Apparently because of the change to the stepper motor control to 4 parameters instead of 3. So where do I find the headers to see what the 4 parameters should be?
Regards, Mark

The header is the Sparki.h file. You can see the latest version on our github here:
