Do you want to take part in the VSCP development and change the world


Can’t promise you fame and fortune.  But it can be nice to just be part of something that will change the world.

There is a lot to do of course. It always is. But bindings to different languages (also to languages not in the list)  is something that we really need and gives other people a chance to do great things.   Yes we can do with libs. that is not based on the VSCP helper lib and interface the REST or the websocket interface of the VSCP daemon.

There is a list here with things that we think it would be nice to see. But there is million of other things you can contribute with. Its fin. Its valuable. Its a world changer.


Important change to the VSCP Specification


I made an important change to the VSCP specification today.

The CLASS1_INFORMATION, Type = 9 (0x09) Node Heartbeat has previously not been mandatory to implement for a node.  But this has changed and it is now mandatory as the only exception of a mandatory event to implement outside of the CLASS1.PROTOCOL class.   The same is true for the Level II event CLASS2_INFORMATION,

The recommended interval is 30-60 seconds between heartbeats  bur exception can be made for nodes that have to sleep for a longer time.

The reason for this change is that it makes it easier for wireless nodes to announce there presence as they are harder to scan as wired modules.

Changes to the VSCP specification is as always listed here.

A new class has also been added today. This is the Level II class Class=1060 (0x424) Measurement float. This class is a companion class to the Class=1040 (0x410) Measurement string.   Both follow the CLASS1_MEASUREMENT class types except that it allow for more sensors (0-256) and more units (0-256).  Obviously the Level I definition is the interchangeable one.


Yes there is plenty of them already.  But this double precision floating point class can make some order again and I will add translators from all other classes to this class in the daemon and in the CAN4VSCP driver. So for all work at higher levels these to classes are the one that should be used.  At least if not communicating things down to Level I nodes.

Be Hungry – Stay Foolish!


Life of an open source programmer


I am a programmer. Yes a musician to.  But most of all a programmer. Yes for sure. No question about that.

At Friday last week I started to do a reversion of the REST interface of the VSCP daemon.  Nothing strange. I do that all the time.  A fast reversion. A day to fix.

Today, Tuesday,  after working on this, including the  weekend,  since then, I am still at it.  And I will be the rest of the day. At least.

Oh well. Nothing strange. Life of a programmer. In this project I have been at it for fifteen years.

The question is why? The fix I spent so much effort on the last couple of days will hardly be noted by anyone.  Is it worth it?  Is it worth the time I could have spent on other things? Is it worth the money I spend to keep this going, money that I probably never will get back?

I don’t know. But I will continue. Life of an open source programmer. Stupid people.


Ethernet boards and CAN4VSCP power

Two Ethernet boards designed.  That is Ethernet <-> CAN4VSCP. Powered from the CAN4VSCP bus as all other CAN4VSCP modules. Maybe there will be a version with generic Ethernet <-> CAN  as well in the future.

The board are designed in two versions. A Microchip PIC and an ARM version.  We will probably go for just one of them in the end.  This is the first step in a switch to ARM in our product line.

The Ethernet board will be able to plug and playish connect to the VSCP daemon but could also work alone on a segment and as a port out in the world for remote controlled equipment.

Need to sell some more of the other stuff before they can go into production though.  Earn money before spending them is the mantra here. So shop as crazy from the FrogShop. 😉

The other two modules are power injectors for CAN4VSCP. Two version. A big a and a small.  The samll version just powers a RJ-45 while the big have 16 daisy chain connectors.
