Hi Steve,
As I'm quite new to BrickOS and to C programming, I'm sorry I'm not sure I
understood what you meant, neither how you do this :

- Do you check the sensor at a higher rate, and only send a command to the motor
at 1kHz ?
- How do you get this command to be looping at 1kHz (I do not know yet how time
is managed within BrickOS) ?
- Is it better to run two tasks independently, one for sensor checking, and one
for motor command sending ?
Maybe you'd have a sample to show how you proces this ?
Thanks, best regards,
Francois
