Velleman K8055 Plugin V1.0.0

[Bestgear]

Malarcy/Andrew

What would be the position to change the plugin so that it only uses the outputs of the board?

From memory, I had no co-existance issues until the inputs were used, then bad news.

Would multi boards be possible if it was used for outputs only?

What about board 1 used for I/O and boards 2,3,4 for O only?

Outputs would obviously remove polling...

Its only £35 for 64 outputs!

Right now, its outputs I need! I have moved over to gamepads for inputs....

outputs less of an issue - the board switch time doesn't really matter unless you care if it takes .25 seconds to turn an output "on".

It wouldn't be hard to do - but time is the issue - I have zero at the moment (updating this via a smartphone sat outside the kids school waiting for one of them to finish doing something.....)

DJ - you keep finding kit I wanna buy and play with and I know I don;t have the time to do it.

My instant reaction to this is that something could be written that lived outside of homeseer - so you could call it from a script when you needed to switch an output - not as nice as a plugin but a hell of a lot quicker to write and since it doesn't need any input stuff it's an easier target.

Don't know if there would be any interactions with HID with this unit - but the board seems like god's gift to us h/a folks - with the appropriate addon circuits you can drive relays and whatever else you like.

If they had a com object or a .net equivalent (excuse the .net "Blindness" - I code in C - and the last commercial project I did was a device driver for Windows NT 4.......) it would be trivial - as it stands someone has to write the .net or com interface.

I won't volunteer, but this looks like a good project for someone.

Hi Malarcy

Yes, it seems a good find - I did follow a feew "PC-Bee" devices a while ago, and I think this looks like it came from the same family.

I spoke to the manufacturer/supplier and they confirmed that there are no known issues with HID device compatibility.

With regards to the polling of inputs, their reply was:

"You have to poll the inputs. When you use the ReadInputs() function it
sends a message to the device to latch the inputs. It then reads the latch
and returns the 16 bit value."

So, that kinda excludes them for input duties!

So, I wonder if Andrew is up for the challenge?

on a single board polling (whilst not ideal) isn't a problem really (you can potentially miss an "on" - but you could solve that with some circuit that holds on for a period of time). It is easy to say in the code every .25 seconds - go read the inputs, the problem with multiboard velleman was you had to say every .25 seconds switch board, read inputs, switch board read inputs etc. 1 for each board - and it took about .3 of a second to respond - so every .25 secs you asked for 1.2 secs of work - it spent all it's time polling.

The bees are interesting but I'm interested in the analogue I/O offered by the Velleman. I would like to eventually control my colour LED room lighting.

K8000 Plugin

Hi,

Malarcy,

I'm using 3 velleman K8000 boards.

Because I don't know how to develop a plugin to Hs, inside hs events, I'am launching Vbapplications to read and write to the k8000. After doing the task the executable will close... works, but (...)

Do you intend to develop a plugin to this boards?

[Malarcy]

No plans for any development projects at the moment - my home automation habit has to take a back seat at the moment - too many other things in my life I am afraid.

There may be some other takers around who might be interested.

Hi Antoliveira,

If you wrote these VB aplications yourself then you may be able to write a plugin yourself. If you download the SDK from the installer, it gives a good example. Have a look?

Hi,

Thanks for the comments.

I think the lack of time is a common problem to all of us

Andrew, are you talking about the V2 installer, right?

I'm still working with HS V1.7 and the vb programms I wrote to control the K8000 boards use the active x issue, I think the method to "talk" with hs2 is different.

As soon as possible (time problems) I intend to move to HsV2x, maybe at that time I could try to understand how to do a plugin to hs, based on my Vb project...

... I'm not a programmer, just trying to do my best...

[Andrew]

Yes V2. Its the best any of us can do. Maybe we could Collaborate if we both get time to start on our projects?

Are you also interested on the K8000?

I use it mainly for analogic to digital conversions and not critical (recurring) digital input

No sorry, I have a K8055.
