    sgjava got a reaction from chwe in ArmbianIO API proposal   
    @chwe I've looked at the Node-Red demo and it looks interesting to make work flows, but if you look at you'll see it's pretty involved. The nice thing though is it would support many more SBCs by ArmbianIO's very nature. @Larry Bank and I were discussing adding PWM yesterday, board name detection (see @tkaiser's comments above), etc., so there's still some core functionality to add at the C level and then to the wrappers. Of course being an Open Source project any one can contribute

    See 8 posts above or
    Edit: When asking @jernej back then whether he's fine with his code being used in other projects IIRC he had no objections.

    I've changed the way the Python wrapper is generated using ctypesgen instead of Swig. This makes the shared library much smaller because it doesn't have any Swig junk linked in. It's basically just a shared version of what @Larry Bank's make builds with the static library (maybe we should add an #IFDEF for that, so I don't have to compile it). There no need to load the library in your code since ctypesgen handles that in the it creates. Your Python code is more elegant and there's no mixing Swig shit code with ctypes or weirdo interface files just to deal with pointers. I'm going to generate the JNA code as well for Java just so I don't have to maintain the interface file if the underlying C API changes. Not sure about JavaScript yet, but if I can find a generator that deals with pointers well then maybe I'll try that next. Here's the obligatory Button program using a callback:
    import time from armbianio.armbianio import * # Simple callback displays pin and value def buttonCallback(iPin, iEdge): print "Button state: pin = %d, value = %d" % (iPin, iEdge) # Detect SBC rc = AIOInit() if rc == 1: # Function returns char array print "Running on a %s" % AIOGetBoardName(); if AIOHasButton(): button = 0 # Button callback AIOAddGPIOCallback(button, EDGE_BOTH, AIOCALLBACK(buttonCallback)); print "Press/release button a few times\n" time.sleep(10) # Remove callback AIORemoveGPIO(0) else: print "%s does not have a button" % AIOGetBoardName(); AIOShutdown() else: print "AIOInit error"

    I've created Python bindings with Swig using a script that should install all dependencies and create an armbianio module and install locally with pip, so it's globally accessible in Python. I created a PR for Larry, but you can grab it at until the merge happens. I included a simple LED blink program that uses pin 12 (ArmbianIO mapping) for the NanoPi Duo. It would be nice to test other SBCs as well.
