how to control servo with interrupt mode

2010-10-10T12:43:53+01:00

Just a comment:

With the speed of the Roboard, you can change the PWM output faster than the servo can respond to the changes WITHOUT using interrupts. The only reason I can think of that you would want to use interrupts on PWM is if you are using "counting mode" on the PWM outputs and want to signal when done. It's easier to use "continuous mode" and alter your PWM as needed than it would be to write the kernel-mode driver.

Hi,

currently, the RC Servo lib of RoBoIO doesn't support interrupt control. If you need PWM interrupt capability, you can employ the PWM lib for this purpose (see pwm.h & pwmdx.h for PWM lib API).

Note that for WinXP & Linux, to use the PWM interrupt, you will need to write an XP/Linux driver for handling the interrupt events.

Hi,
Could you give me sample code how to control servo with interrupt mode? because I need fast respons of servo.
Because if I use tutorial in http://www.roboard.com/download_ml.htm is not enough.

help me please. thanks.
