Reading from a keyboard?

[HipsterBrown]

@danawoodman No. If you install version 0.5.4 (npm install [email protected]) then you can use it now. Otherwise, yes, you will need to wait.

[HipsterBrown]

Yes, you should be able to use something like node-hid to read data events from the USB stack .

[danawoodman]

@HipsterBrown thanks! Does node-hid support the tessel platform?

[HipsterBrown]

Yes, we have compiled binaries for the native dependencies of node-hid version 0.5.4 to work on Tessel's architecture (mipsel).

I can push compiled binaries for the latest release of node-hid (v0.7.2) sometime this week.

[danawoodman]

@HipsterBrown thanks, does that mean I have to wait to use node-hid until that binary is released?

[danawoodman]

I installed that version and setup their "hello world":

const HID = require('node-hid')
const devices = HID.devices()

console.log('DEVICES:', devices)

Getting this with a keyboard connected:

node: can't resolve symbol 'libiconv_open'

If I unplug the keyboard I get and empty array (which makes sense)

Any ideas?

[danawoodman]

@HipsterBrown do you have time to push the v0.7.2 version? Maybe that is the issue?

[rwaldron]

@danawoodman I've cross compiled v0.7.2 and uploaded it just now

[danawoodman]

I updated to the newest version but I am still getting:

path.js:7
    throw new TypeError('Path must be a string. Received ' + inspect(path));
    ^

TypeError: Path must be a string. Received undefined

With this code:

const hid = require('node-hid')
console.log(hid.devices())

Any suggestions?

[danawoodman]

Has anyone ever been able to get node-hid working on a Tessel? This is becoming really frustrating because I bought the Tessel specifically to use a USB RFID reader (the module won't work as it is the wrong frequency). Someone please save my day! 😚
