hello, i don´t find a code to control a servo over PWM into a DigitalIN. my idea: if DigitalIn left(p10)..............servo get to the left if not DigitalIn left(p10)..........servo get to the middle if DigitalIn right(p11..............servo get to the right if not DigitalIn rigth(p11).........servo get to the middle i have no ideas to do that? is this difficulty? can anywhere help me?? thanks

Checkout this page: http://mbed.org/cookbook/Servo It should be easy to change this software into what you need by using 2 DigitalIn pins to control the servo instead of characters received on the serial port.

i know. my idea #include "mbed.h" #include "Servo.h" DigitalIn taste(p10); DigitalIn taste2(p12); DigitalIn taste3(p11); Servo myservo(p21); int main() { float range = 0.0005; float position = 0.5; while(1) { switch() { case 'taste': position = 0.0; break; case 'taste2': position = 0.5; break; case 'taste3': position = 1.0; break; myservo.calibrate(range, 45.0); myservo = position; } }

it dosen´t work it i am a absolute beginner

oh thanks for the tip. jes this is the program that i written (copy/paste from servo page). i don´t will use the usb serial with the key from keyboard (1,2,3...). i will use the digital in options. I have 2 switches plugged to the mbed. the first for left forwarding, the second for right forwaring. is no switched to be used the servo go to the middle. thanks for helping

include "mbed.h"
include "Servo.h"

DigitalIn taste(p10);
DigitalIn taste2(p12);

Servo myservo(p21);

int main() {
   float range = 0.0005;
   float position = 0.5;
   myservo.calibrate(range, 45.0); // init the servo
 
   while (1) {  // Do the next actions forever
        position = 0.5;      // default is middle position (no or both buttons pressed)
                                           
        // test to see if any buttons are pressed
        if (( taste) & (!taste2)) position = 0.0; // left on only taste pressed 
        if ((!taste) & ( taste2)) position = 1.0; // right on only taste2 pressed

        myservo = position;             // activate the new position
  }
}

include "mbed.h"
include "Servo.h"

DigitalIn taste(p10);
DigitalIn taste2(p12);
DigitalIn taste3(p11);
Servo myservo(p21);

int main() {
    int code;
    float range = 0.0005;
    float position = 0.5;
    myservo.calibrate(range, 45.0);

    while (1) {
        code = (taste3 * 4) + (taste2 * 2) + (taste); //binary encoded buttons

        switch (code) {
            case 1:
                position = 0.0; //taste
                break;
            case 2:
                position = 1.0; //taste2  
                break;
            case 4:
                position = 0.5; //taste3
                break;
            default: 
                position = 0.5; //all other combinations
                break;
        }

        myservo = position;
    }
}

This should work. The switch statement above was wrong. <<code>> include "mbed.h" include "Servo.h" DigitalIn taste(p10); DigitalIn taste2(p12); Servo myservo(p21); int main() { float range = 0.0005; float position = 0.5; myservo.calibrate(range, 45.0); // init the servo while (1) { // Do the next actions forever position = 0.5; // default is middle position (no or both buttons pressed) // test to see if any buttons are pressed if (( taste) & (!taste2)) position = 0.0; // left on only taste pressed if ((!taste) & ( taste2)) position = 1.0; // right on only taste2 pressed myservo = position; // activate the new position } } <</code>> The switch statement could be used like this. <<code>> include "mbed.h" include "Servo.h" DigitalIn taste(p10); DigitalIn taste2(p12); DigitalIn taste3(p11); Servo myservo(p21); int main() { int code; float range = 0.0005; float position = 0.5; myservo.calibrate(range, 45.0); while (1) { code = (taste3 * 4) + (taste2 * 2) + (taste); //binary encoded buttons switch (code) { case 1: position = 0.0; //taste break; case 2: position = 1.0; //taste2 break; case 4: position = 0.5; //taste3 break; default: position = 0.5; //all other combinations break; } myservo = position; } } <</code>>

thanks! thats good. but in the code is a little failure :-) in the code line taste3 :-) I use your code later at home. Greets and thanks
