6. Kijk met WinSCP of bestand /dev/i2c-1 bestaat.

7. Maak bestand lees en schrijfbaar.

sudo chmod o+rw /dev/i2c*

1. Rechten zijn nu rw-rw-rw-

2. test i2c

naar Root user

sudo su

curl -fsSL https://deb.nodesource.com/setup_14.x | bash -

Now install it by running:

apt-get install -y nodejs

su pi

npm install node-mcp23017 --save

• Pin 4 5V Power - Rood
• Pin 6 Ground - Bruin
• Pin 12 GPIO 18 - Oranje

1. get https://github.com/srcshelton/servoblaster/
2. kopieer de bestanden van servoblaster naar control/servoblaster
3. open terminal op PI
4. ga naar folder control

   cd control
   

5. ga naar folder servoblaster

   cd servoblaster
   

6. maak uitvoerbare servoblaster bestanden van servod.c met commando make

   make
   

   • resultaat

     cc -I/opt/vc/include -Wall -Wextra -g -O2 -mcpu=native -o servod servod.c mailbox.c -L/opt/vc/lib -lm -lbcm_host
     

7. installeer blaster

   sudo make install
   

   • resultaat

     [ "`id -u`" = "0" ] || { echo "Must be run as root"; exit 1; }
     install -d -m 0755 -o root -g root /usr/local/sbin
     install -d -m 0755 -o root -g root /etc/init.d
     install -bCSv -m 0755 -o root -g root servod /usr/local/sbin/servod
     install -bCSv -m 0755 -o root -g root init.sysv /etc/init.d/servoblaster
     update-rc.d servoblaster defaults 92 08
     #/etc/init.d/servoblaster start
     

8. wijzig rechten anders werkt ./servod niet

   sudo chmod 777 /dev
   sudo chmod 777 /dev/mem
   

9. Instellen pwm signaal. Start dit programma in de achtergrond m.b.v. &. Druk enter na opstarten

   sudo ./servod --pcm&
   

10. Test kanaal 2 / P1-12 heen

    echo P1-12=100 > /dev/servoblaster
    

11. Test kanaal 2 / P1-12 terug

    echo P1-12=150 > /dev/servoblaster
    

Using PCM is a better option, as the 3.5mm jack also uses the PWM peripheral, so ServoBlaster can interfere with sound output. In my case 3.5mm jack oudio out stoped working in PWM mode, so recommended to run as PCM with --pcm flag.

npm i servoblaster

servoblaster.createWriteStream = function (pin, max = 217, min = 78) {
	var stream = fs.createWriteStream(SERVOBLASTER_DEV);
	var servo = servoblaster.Transform({ pin: pin });
	servo.pipe(stream);

	stream.on('error', function (err) {
		servo.emit('error', err);
	});
	stream.on('open', function () {
		servo.emit('open');
	});
	servo.pos = (pos) => {
		pos = String(min + parseInt((max-min)/100*pos));
		// console.log(pos);
		servo.write(pos);
	}
	return servo;
};
