    Jon, Try this

    Buttons 1,2,3,4 and 5 didn't work initially. Go to device status and send an ON to each and then try the Digital Inputs.

    Digital Inputs

    Hi Jon
    I just tested my Digital inputs. I ceated a script that speaks Button X was just pressed. Set trigger to set any status and it works fine.

    Hi MaLarcy,

    Just built the K8055 board, tested with the demo program and everything works OK.

    I have just tried your plugin and all inputs/outputs work except the 5 digital inputs. The 5 devices corresponding to these inputs keep a value of unknown. The buttons have been held down for more than 1 second BTW. I have tried both versions of the DLL with the same result. If I shut down HS and load the demo program again, these 5 buttons register correctly on the software so the hardware must be working.

    FYI, I run a 3 gig P4 with Homeseer. Thought you would like the feedback.

    Thanks very much for the work you have done on this plugin so far!

    It works

    I'm not sure what time it is in the UK, sometime Tuesday am. Here in Springfield Illinois it's 9:34 PM and I would like to say "IT WORKS GREAT". Yes, I was shouting. Thought I might wake you up.
    I finished my 8055 board Saturday morning. The demo program that comes with it helped prove that all functions work. I followed your install instructiins and just as you said all of the devices appeared. I'm off tomorrow, can't wait to see what I can interface it to. I'llbe checking back with feedback soon.
    Thanks again for the plug-in.

    Velleman K8055 Plugin V1.0.0

    I have developed a plugin for the velleman k8055 usb io board - described in this thread also at this website

    Basically usb connected 5 digital inputs, 8 digital outputs, 2 analog in 2 analog out all at about 20 pounds in kit form - winner!


    Install the velleman demo program - this will put the dll in the right place, and you can also check your board works - NOTE: The velleman site has a newer DLL - apparently fixes a memory leak - I haven't downloaded and tested it yet - I will do once the digital ink has dried on this plugin, but you may want to try it - let me know if it works OK....

    Plugin description:

    Supports 1 velleman board currently
    Provides 19 devices,

    5 digital inputs - devices K8055-0-DI1..5
    2 analog input - devices K8055-0-AI1..2
    8 digital output - devices K8055-0-DO1..8
    2 analog output - devices K8055-0-AO1..2
    2 counters - devices K8055-0-DC1..2 (counts the number of times digital input 1 and 2 have been "triggered".


    Copy hspi_malk8055.ocx to your homeseer directory (c:\program files\homeseer as a guess)

    Fire up homeseer, view.. options.. interfaces.. plugins drop down select malk8055
    restart homeseer with your velleman board attached

    If all goes well new devices appear - restart one more time to get the initial values.

    Using it - press the buttons on the velleman board - homeseer devices should change from off to on - (this version has a 250ms fixed poll interval - will fix that in next release - so you have to hold it for .25 secs to get it to register)

    skin resistance should be enough to get the analog inputs working - I tested mine with a wet finger.

    digital outputs - set them on from the device menu - light should come on.

    analog outputs - I drive them from a script -

    for i = 1 to 255
    hs.setdevicevalue "[16",i

    Makes the output test light go from dim to bright.

    digital counters - press the input buttons for di 1 and 2 and watch the numbers go up - right click in device view - goto properties and then configure - you can set the switch debounce times in there and chose to preserve counter values over a homeseer restart.

    Think thats about it apart from the disclaimers


    The plugin is currently (and for the forseable future) free - I am not making the source code public at the moment (open to email conversations if you want it) - if/when I get bored of it I will publish source.

    Please let me know if it works or fails - I will be issuing some updates but I was keen to get it published.
