thanks for your quick reply. Yes i know that functions. I’m also very familiar with the code of the original lego firmware. I’m creating a robot which controls a kind of pendulum. So i have to write functions which accelerate the motors slow, linear and exponential. With exponential i mean the inverted way of ramp up and ramp down which is implemented in the lms_pwm device (or you can call it the driver of the motors from lego).
And i want to trigger other functions when the pendulum is in a specific position.
I also tried to realize it with the EV3-C/EVC Api but the “GetRotationCount” function is also slow there.
Do you know why?
