servo issue

David van der Tuijn

Hi,


When i test one servo at a time it goes perfect; but when i connect them both they "rotate" very slowly.

[noparse][[/noparse]code]
CPU.pulseOut(650, CPU.pins[noparse][[/noparse]12]);
CPU.pulseOut(850, CPU.pins[noparse][[/noparse]13]);
CPU.delay(20);
[noparse][[/noparse]/code]

Can it be programmed so it will "rotate" faster ?

Could this be a power issue?
Please post (attach) entire code.

regards peter

650 and 850 are counter rotation instructions...they should move. Not sure why they are going slowly, however. What are you using for power? What is your connection scheme?

Tryed a different code; same result :

[noparse][[/noparse]code]

import stamp.core.*;

public class BoeBot
{

· static PWM pwmL = new PWM(CPU.pin12,173,2304);
· static PWM pwmR = new PWM(CPU.pin13,173,2304);

· public static void main()
· {
··· pwmL.update (220, 2304);
··· pwmR.update (126, 2304);
· }

}

[noparse][[/noparse]/code]

The servo's are directly connected to P12 and P13 (Carrier Board)

Using different power sources (adapter 6V, 9V, 4x 1.5V battery's) does not change the situation.

I think its the Adapter wich is only 500mA and low battery's
