In Topic: Anyone have a good PWM example for Netduino Plus 2?

13 March 2013 - 11:05 AM

I got it working now using the solution below:

 

[color=rgb(40,40,40);font-family:helvetica, arial, sans-serif;]"If you're using AnalogInput, add the SecretLabs.NETMF.Hardware.AnalogInput.dll assembly as a reference to your project. If you're using PWM, add the SecretLabs.NETMF.Hardware.PWM.dll assembly as a reference to your project."[/color]

Thanks very much, I finally made it working by following your advise:

I cannot find setpulse() function on netduino 2. how can I run the code below in netduino 2?

 

Making Music example

 

public static void Main()
{
// write your code here
// store the notes on the music scale and their associated pulse lengths
System.Collections.Hashtable scale = new System.Collections.Hashtable();
// low octave
scale.Add("c", 1915u);
scale.Add("d", 1700u);
scale.Add("e", 1519u);
scale.Add("f", 1432u);
scale.Add("g", 1275u);
scale.Add("a", 1136u);
scale.Add("b", 1014u);
// high octave
scale.Add("C", 956u);
scale.Add("D", 851u);
scale.Add("E", 758u);
// silence ("hold note")
scale.Add("h", 0u);
int beatsPerMinute = 90;
int beatTimeInMilliseconds =
60000 / beatsPerMinute; // 60,000 milliseconds per minute
int pauseTimeInMilliseconds = (int)(beatTimeInMilliseconds * 0.1);
// define the song (letter of note followed by length of note)
string song = "C1C1C1g1a1a1g2E1E1D1D1C2";
// define the speaker
PWM speaker = new PWM(Pins.GPIO_PIN_D5);
// interpret and play the song
for (int i = 0; i < song.Length; i += 2)
{
// extract each note and its length in beats
string note = song.Substring(i, 1);
int beatCount = int.Parse(song.Substring(i + 1, 1));
// look up the note duration (in microseconds)
uint noteDuration = (uint)scale[note];
// play the note for the desired number of beats
speaker.SetPulse(noteDuration * 2, noteDuration);
Thread.Sleep(
beatTimeInMilliseconds * beatCount - pauseTimeInMilliseconds);
// pause for 1/10th of a beat in between every note.
speaker.SetDutyCycle(0);
Thread.Sleep(pauseTimeInMilliseconds);
}
Thread.Sleep(Timeout.Infinite);
}
