Hi Hajime,
Here's the rundown for connecting the servo to the Handy Board:
1) Assuming you're using digital port 9, you will need a connector like this:
_
=====| |== <--- connect the WHITE wire from the servo here
| | <--- remove pin to polarize plug
=====| |== <--- connect the RED wire from the servo here
=====|_|== <--- connect the BLACK wire from the servo here
2) Edit the file lib_hb.lis to include the following line:
servo.lis
3) Make sure you have a file called servo.lis. If not, make one and include:
servo.icb
servo.asm
4) Make sure IC is configured to load up lib_hb.lis as the default library
by typing:
ic -config
5) After everything is set up, you can run IC to test your servo.
servo_on(); <- enables the servo
servo(int period); <- period is in useconds (center = 1520)
servo_deg(float angle); <- angle is float in degrees (i.e. 90.0)
servo_rad(float angle); <- anlge is float in radians
servo_off(); <- disables the servo
The drawback to this approach is the servo runs off the same regulated
power that the processor runs from. I've never had problems with the servo
disrupting the 6811 but it could happen.
Hope that helps!

| Hello! Could anybody please tell me the proper step in controlling the servo motor by HB ? ^s I connected the servo motor to the HB and typed in the servo motor control functions but none of them are working... Thanks in advance. (28 years ago, 17-Jul-96, to lugnet.robotics.handyboard)
