This is a top-level interface to an rfid reader and writer that happens to double as a very nice glowy thing. The library itself have been written to support multiple skyportals on the one machine allowing you do so some pretty neat things when you have a few usb ports spare :)
This module does just the bare bones required to communicate with the device, but does make interfacing with a skyportal pretty accessible. The follow example demonstrates opening a portal and setting it's color to green.
var skyportal = ;var commands = skyportalcommands;skyportal;
NOTE: Running the examples (at least on my machine required root user
privileges to open the device, so you may need to
sudo the examples).
At this stage this has only been tested with the USB version of the portal (Xbox 360) on Linux. It has been coded in such a way that compatibility with other portal models is quite easy to implement, so feel to send through a pull request :)
You may need to apply some system updates to get it working though, see the following url for more info:
Look for a skyportal within the current usb devices.
init function of the skyportal module is best way to get yourself a
correctly open initialized portal. In short, you should pretty much
always use it.
Open the portal using the portal data that has been retrieved from a find operation.
Read data from the portal.
Send a chunk of bytes to the portal. If required the device appropriate command prefix will be prepended to the bytes before sending.
Release the portal device bindings.
These are command generators for commands supported on the device.
The activate command is sent to the device after a reset.
Update the color of the glowing thing by providing rgb values. This function also supports providing a three element array as the first argument for rgb.
[0x43, 0xRR, 0xGG, 0xBB]
Query a tag that is currently on the portal. Data is returned in blocks,
so use the
blockIdx to target a specific block of data.
[0x51, 0x20 + tagIdx, blockIdx]### resetReset the device ready for use.
