Subject: Raspberry PI Model 2 - PWM
Message-ID: <563C053E.6000705@coldbits.com>

Is it possible to do PWM with jdk.dio and the raspberry pi Model 2? I know that 
my hardware is setup correctly and I can get an LED to blink but I need to get 
PWM working for my motor control sub-system.  Any help or pointers would be 
welcomed.

Subject: dio.properties for RPI model 2
Message-ID: <56413930.2050603@coldbits.com>

Does anyone have a good example of the dio.properties file for the Raspberry PI 
model 2?  The one in the dev branch appears to be for one of the earlier 
models.  I would be good if there was a file for each model of the raspberry pi.

I would be willing to help produce these files but I only have a RPI model 2 for 
testing.

Is this project active?  I was hoping for some pointers on how to do PWM with 
the raspberry PI.

Hey Andrew,

I've tried but using dio or Pi4J I couldn't simulate a PWM.

Best,

Jeff is right. Linux kernel contains no public API for PWM, therefore DIO doesn?t support such kind of devices

Hi Jeff,

You should be able to use PWM with Pi4J.

Simple hardware PWM example:

package gpio.test;


import com.pi4j.io.gpio.GpioController;
import com.pi4j.io.gpio.GpioFactory;
import com.pi4j.io.gpio.GpioPinPwmOutput;
import com.pi4j.io.gpio.RaspiPin;


public class PwmTest {

   /**
     * @param args the command line arguments
     * @throws java.lang.InterruptedException
     */
    public static void main(String[] args) throws InterruptedException {

        GpioController gpio = GpioFactory.getInstance();
        GpioPinPwmOutput pwm = gpio.provisionPwmOutputPin(RaspiPin.GPIO_24);
        pwm.setPwm(500);

        // keep program running until user aborts (CTRL-C)
        for (;;) { Thread.sleep(500); }
    }

}


Thanks, Robert

Hi All,

Thanks for the answers.

Robert, first, congratulations for your project. It helped me a lot. But
regarding PWN, I am sorry but I've tried to run your code above in my
RaspberryPis (B+ and 2) couple of months ago for my project Brasilino (
https://github.com/jeffprestes/brasilino) and I couldn't control a servo
motor like I do with Arduino. I believe it's not your code's fault but as
Sergey said a lack of Linux functionality.

Gerrit, I will try to see what possible workaround Michael has created for
this. Thanks for sharing it.

Best,

-Jeff

Hi Jeff,

I'll test PWM out later today on a RPI2b just to verify that its still
working.  Maybe some bug or update was introduced that now causes it to
fail but it was certainly working at one point in the past.  I will verify
PWM output with an oscilloscope.  (Pi4J used WiringPi under the covers
which writes directly to the Broadcom SoC memory to control GPIO, so it
should not be limited to the Linux device/sysfs interface.)

Thanks, Robert

Hi Jeff,

I tested PWM using Pi4J on a Raspberry Pi 2B today and it seems to be
working properly.

I tested the following hardware supported PWM pins on the RPi-2B:
http://pi4j.com/pins/model-2b-rev1.html

   - GPIO_01
   - GPIO_23
   - GPIO_24
   - GPIO_26

I tested on the following versions of Pi4J.

   - 1.0 (release)
   - 1.0.1-SNAPSHOT
   - 1.1-SNAPSHOT


The link below is a snapshot image of the oscilloscope output I used to
verify the PWM signal was present.
https://dl.dropboxusercontent.com/u/24688272/RPI2B-Pi4J-PWM-24.png

Thanks, Robert
