electron-microfet2

microFET2

Nodejs library to access the microFET 2 data

var MicroFET2 = require('electron-microfet2');

var sensor = new MicroFET2();

//listen for device found event and connect
sensor.on('found', (devices) => {
  devices.forEach((device) => {
    sensor.connect(device.id, device.name, device.port);
  });
});

//listen for connection and start streaming
sensor.on('connect', (device) => {
  console.log("microFET2 connected");
});

//listen for data
sensor.on('data', (data) => {
  console.log(data);
});

//look for devices to connect to
sensor.detect();

//close the connection after 5 seconds
setTimeout(function(){
    sensor.disconnect();
    console.log("microFET2 disconnected");
}, 5000);

Serial Data Stream For MicroFET 2, ErgoFET 150 and ErgoFET 300

• 9600 baud, 8 data, 1 stop, no parity
• 4 bytes are sent
• byte.bit(0-7) example: 3.2 is set - third byte bit 2 set

Byte 1 = 255

2.7 1 NA

2.6 NA

2.5 1=low range 0=high range

2.4-2.1 NA

2.0 1=force reading negative (tension) 0=force reading positive (compression) ErgoFET only

byte 3 � Most significant 2 digits (99 maximum)

Byte 4 � least significant 2 digits (99 maximum)

Example: byte 3=12 and byte 4=26 then the force reading is 122.6 pounds
