AnalogWriteSync?

[cautiousCentaur]

Is there a way to get synchronous AnalogWrite? I don't see it in the docs? Here is the code i want to migrate from stock bonescript:

function GrowVent(in1,in2,enable){
    var self = this;
    self.vent_speed = 0.39; //voltage, controls speed, a calibrated valuw
    self.vent_wait = 900; //milliseconds, a calibrated value
    self.in1 = in1;
    self.in2 = in2;
    self.state = 0;
    self.enable = enable;
    bone.pinMode(self.in1, 'out');
    bone.pinMode(self.in2, 'out');
    //bone.pinMode(self.enable, bone.ANALOG_OUTPUT);
    self.Open = function(){
        bone.digitalWrite(self.in1,1);
        bone.digitalWrite(self.in2,0);
        bone.analogWrite(self.enable,self.vent_speed);
        setTimeout(bone.analogWrite, self.vent_wait, self.enable, 0.0);
        self.state = 1;
    }
    self.Close = function(){
        bone.digitalWrite(self.in1,0);
        bone.digitalWrite(self.in2,1);
        bone.analogWrite(self.enable,self.vent_speed);
        setTimeout(bone.analogWrite, self.vent_wait, self.enable, 0.0);
        self.state = 0;
    }
}    
Vent_main = new GrowVent("P8_14", "P8_7", "P9_29");

Unfortunately, the way linux kernel is made, it is not much possible to write analogWriteSync function. Instead,I would write code like this. Let me know if you face any issues.

var GrowVent = {
    vent_speed : 0.39, //voltage, controls speed, a calibrated valuw
    vent_wait : 900, //milliseconds, a calibrated value
    in1 : null,
    in2 : null,
    state : 0,
    enable : null,
    init : function(in1, in2, enable){
         this.in1 = in1;
         this.in2 = in2;
         this.enable = enable;
         bone.pinMode(in1, 'out');
         bone.pinMode(in2, 'out');
    },
    open : function(){
        var self = this;
        bone.digitalWriteSync(self.in1,1);
        bone.digitalWriteSync(self.in2,0);
        bone.analogWrite(self.enable, self.vent_speed, 2000, function(err){ // the callback function will be called when the pin is analog written. It will then put setTimeout.
            setTimeout(function(){
                  bone.analogWrite(self.enable, 0);
            ,self.wait);
           self.state = 1;
        });
    },
    close : function(){
        var self = this;
        bone.digitalWriteSync(self.in1,0);
        bone.digitalWriteSync(self.in2,1);
        bone.analogWrite(self.enable, self.vent_speed, 2000, function(err){
            setTimeout(function(){
                  bone.analogWrite(self.enable, 0);
            ,self.wait);
           self.state = 1;
        });
    }
}    
Vent_main = new GrowVent("P8_14", "P8_7", "P9_29");

GrowVent.init("P8_14","P8_7","P9_29"); // this is async call,it will take some time. You can replace pinMode with pinModeSync in init function to make it sync.
GrowVent.open(); // this will also be async call. Let me know if you want to make it sync. I will write code for it.
GrowVent.close(); // this will be async call, let me know if you want to make it sync.

For others that may see this, could you show synchronous open and close methods ?

What could cause this error?

function GrowVent(in1,in2,enable){
    var self = this;
    self.vent_speed = 0.2;//0.39; //voltage, controls speed, a calibrated value
    self.vent_wait = 200;//900; //milliseconds, a calibrated value
    self.in1 = in1;
    self.in2 = in2;
    self.state = 0;
    self.enable = enable;
    bone.pinModeSync(self.in1, 'out');
    bone.pinModeSync(self.in2, 'out');
    bone.pinModeSync(self.enable, bone.ANALOG_OUTPUT);
    self.Open = function(){
        bone.digitalWriteSync(self.in1,0);
        bone.digitalWriteSync(self.in2,1);
        bone.analogWrite(self.enable,self.vent_speed,2000.0,function(){
            setTimeout(bone.analogWrite, self.vent_wait, self.enable, 0.0);
            self.state = 1;
    });}
    self.Close = function(){
        bone.digitalWriteSync(self.in1,1);
        bone.digitalWriteSync(self.in2,0);
        bone.analogWrite(self.enable,self.vent_speed,2000.0,function(){
            setTimeout(bone.analogWrite, self.vent_wait, self.enable, 0.0);
            self.state = 0;
    });}
}

That means the pin is used by some other cape. Did you load any other cape? If not, please try some other pin. Is it that you must use P8_12?

[cautiousCentaur]

I ran this code directly from boot. is something built in that is using a cape? I'm trying to use every pwm so I need this pin to work. On Apr 2, 2016 3:11 PM, "Aditya Patadia" notifications@github.com wrote:

Let me check P8_12 and get back to you.

[cautiousCentaur]

wait,I never said P8_12... My trouble is with P9_31 and P9_14.

Thanks,

Your error output says P8_12 is not available to write. Anyway let me test all 3 pins. You can expect response in 3-4 days.

@kory44 Assuming you are using debian with cape manager support, you may want to check to see if the universal cape is loaded.

a check of ‘cat /sys/devices/platform/bone_capemgr/slots’ output is

0: PF---- -1
1: PF---- -1
2: PF---- -1
3: PF---- -1

if there is no 4: with a universal cape that may be the issue.

Please let us know if it was resolved?
