Pwm and pot

Ryan M. · #1 29-01-2006, 15:44

All you have to do is directly map the pot values to the PWM the servo is on:

Code:

pwm01 = rc_ana_in01;

Change the ports to what you are actually using.

If you need more complicated control... make it more complicated yourself.

--EDIT--
See below message.

Actually, you'd have to do something more like:

Code:

pwm01 = Get_Analog_Value(rc_ana_in01) >> 2;

The controller doesn't sample the analog inputs until you call Get_Analog_Value, and the shift is to convert the 10-bit analog input to the 8-bit PWM output.

Yep... my mistake.

Both the above should work, The first is if the pot is connected to the OI (operator control) the second is if the pot is on the robot. Just fill in the correct context and you are good to go.
