I am in the process of writing a library for the BeagleBoneBlack and was
wondering if anyone here is hacking around with it as well and can test
it out/give me feedback.
http://beagleboard.org/Products/BeagleBone%20Black
My library requires upgrading to a relatively recent kernel. I'm using
Robert Nelson's latest Ubuntu kernel, 3.8.13-bone26,
http://rcn-ee.net/deb/raring-armhf/v3.8.13-bone26/, though any of his
3.8 versions should provide the necessary functionality.
The main thing for those using it is I am limiting it to a recent kernel
so I don't have to chase down 2 different ways of handling the pin
interface. Everything will depend on the linux device-tree, and all the
pins are accessed from PHP by reading and writing to the /sys/class file
structures created for the pins.
Keep in mind this is very much alpha level coding, as I am working
through each interface one at a time, and will be restructuring it
later[for example, right now on my local I have standalone classes
usr-led and gpio-led with methods for configuring/controlling LED's.
Eventually those should be refactored to move common methods into an led
super class with subclasses to override them].
Also at the moment I'm using the much maligned singleton class as it
makes the most sense to me. IE I can't imagine a situation where a PHP
script would have more than one system board since that represents the
entire computer. I can imagine a possible remote-control option, but I
think to support that it would make more sense to re-factor the
singleton Board class into a parent Board class and a couple of
children, the BBBSystemBoard singleton and a BBBWebsocketRemoteBoard class.
Anyone interested have any thoughts on what sorts of functions they
would like?
