Waveshield met KA2284 soundmodule en servo

International Nederlands
1

Hallo,

Graag zou ik wat hulp krijgen bij het volgende:
Ik heb van een waveshield de audio afgetapt om via een 'KA2284 audio shield', een servo te bedienen. Idee is van Jawduino, buttonbanger.com.
Na een paar weken van alles geprobeerd te hebben, heb ik alles werkende (geen foudtmeldingen) behalve de servo. Deze krijg ik maar niet aan de praat(speaking skull :slight_smile: ).

Het grootste gedeelte van de code komt van adafruit.
Wat ik toegevoegd heb is aangegeven met: // incl.KA2284 test Tuesday

Alvast bedankt.

pinMode (pwmjawPin, OUTPUT);

analogWrite(pwmjawPin,outputValue);

wat voor servo gebruik je?

waar staat

#include <Servo.h>

Servo myservo;

void setup()
{
myservo.attach(pwmjawPin);
}

Hallo ArdLab,

Bedankt voor je snelle reactie.

[quote]
#include <Servo.h>

Servo myservo;

void setup()
{
  myservo.attach(pwmjawPin);
}[/quote]

Deze methode was 'ontwikkeld' door buttonbanger zodat je geen library servo.h nodig had. Aangezien de arduino icm wavebord al 2 timers gebruikt.


[/quote]
pinMode (pwmjawPin, OUTPUT); 

analogWrite(pwmjawPin,outputValue);

is dat eenwat voor servo gebruikt je?

Wat bedoel je met bovenstaande?
Het is een simple servo die ook standaard bij arduino geleverd wordt.

zo gebruik ik een servo

Deze

zo gebruik ik een servo

had ik al eens (lang geleden) gelezen. Nu valt mijn oog op het feit dat pin 9 zo-wie-zo niet als pwm te gebruiken is.

Maar ja, het blijkt dat de Uno/waveshield combinatie beide timers gebruikt. Hierdoor worden de libraries van zowel servo.h als ServoTimer2.h niet geaccepteerd in IDE.
Zie hier de foutmelding:

libraries\ServoTimer2-master\ServoTimer2.cpp.o (symbol from plugin): In function `__vector_9':
