Module MMM-Hover dosn't work with the new MM 2.7

@Skorpionbird looks like a breaking change in onoff.js module…

latest fs has started enforcing callback on async operations.

onoff write needs to be fixed like read

Gpio.prototype.read = function (callback) {
  fs.read(this.valueFd, this.readBuffer, 0, 1, 0, function (err, bytes, buf) {
    if (typeof callback === 'function') {
      if (err) {
        return callback(err);
      }

      callback(null, buf[0] === ONE[0] ? 1 : 0);
    }
  });
};

current write

Gpio.prototype.write = function (value, callback) {
  var writeBuffer = value === 1 ? ONE : ZERO;
  fs.write(this.valueFd, writeBuffer, 0, writeBuffer.length, 0, callback);
};

try editing MagicMirror/node_modules/onoff/onoff.js
and changing the Gpio.prototype.write (line 200)
to this

Gpio.prototype.write = function (value, callback) {
  var writeBuffer = value === 1 ? ONE : ZERO;
  fs.write(this.valueFd, writeBuffer, 0, writeBuffer.length, 0, function (err, bytes, buf) {
    if (typeof callback === 'function') {
      if (err) {
        return callback(err);
      }

      callback(null, bytes, buf);
    }
  });
};

I have submitted issue 150 to the onoff module on github

Hi, thanks for the fast reply. I made the change, but I can only test it tonight when I’m home.

@Skorpionbird ok… on the issue I posted, the developer says latest onoff version should work too…

4.1.1, hover-nodejs request 1.1.1 and got 1.2.0

so another thing to try after this, is rename the node_modules/onoff folder to onoff-old
then from MagicMirror folder do

npm install onoff

to get the latest

and try running mirror again…

there are some breaking changes in 4.1.0 and above, so its possible to cause more problems…
