We have today started work on our next module, the Accra counter module. The hardware is already done. This unit will be able to count pulses on four channels and also measure frequency on each channel. It can have alarms set for going over a counter level or when counting down to zero and for a frequency that is outside of a specified frequency range.
It has a built-in linear calculation algorithm that can translate pulse to real world measurement units. This can for example be used for utility meter measurements and gives the correct measurement value sent out on the VSCP bus.
Kilafors will be supplied later as an add on modules to detect S0 (IR) pulses so that Accra can be hooked on to an electrical meter and output power usage data.
This will be the seventh module in the CAN4VSCP series and will be followed by Vilnius for 12-bit A/D measurements.
Last day to put in an application for the IDEA IoT Challenge so i put in one for the VSCP & Friends framework. Bu as soon as I send it away I ask myself “How can something that is ready to deliver today have a chance in a competition like this when everyone else just still talks about what IoT is!? Stupid of me… To late to withdraw it I suppose… 😉
But if you have an IoT idea go ahead, fill in the info.
It’s funny, now we ave so many standard solutions in the form of different consortium’s sp that everything is as it was before. Things will still con be able to talk to each other…
It’s the fourth international Internet of Things day today (IoT day). So today we celebrate a day with cake, balloons and fireworks for all the billions of devices of the world that can’t talk to each other.
Every day now there is a new paper and a new protocol that is said top be the killer protocol. The bigger the company that releases the protocol the more follower it will get and people start to send their data using the protocol. Sometimes the bit’s and zeros also is received by the other side and at least at one occasion I heard of a secure link where the neighbour actually could not see the data. But even if security is forgotten and most can read the data, very few can understand it anyway so it is secure than isn’t it. It’s all OK if the device comes from one manufacturer and the receiver is also from the same manufacturer, but if not there is always problems.
Think of a device sending a temperature today. It may be sent using fancy things like 6LowPan and even MQTT on top of that. Even satellite links may be used. But when it comes through on the other end it is
So what is this “23.43”? Is it a the time when the message was sent? Is it the birth weight of a giraffe? Is it… So we phone the other side and ask. Which is the ISS in this case, orbiting the earth. It’s a temperature they say. In Russian of course but as we took that class so we understand “температура” or at least think we understand, so we hang up. Then we know that some temperature is 23.43 degrees on the IIS orbiting the earth. Hmm… but is it 23.43 degrees Kelvin, or is it 23.43 degrees Celsius, or is it 23.43 degrees Fahrenheit? Or does the Russians have their own Putin scale? If this is the temperature inside the IIS it may matter. So we phone again..
And we should not even look at how we should discover a newly installed device,
configure it to do what we want it to do. If there will be billions of devices and each is configured in its own way we are in for a treat. All talking their own language, all interpreting data differently. Is IoT a joke!?
So for soon fourteen years ago when we started the VSCP project (http://www.vscp.org) we solved this. Just by using some simple abstractions that could live along side all the fancy company developed stuff or even live on its own and do so in the lowest resource end devices. Making devices talk to and understand each other and tell us how they can be configured and what they can do. But I’m sure the IoT headlines also today will present the next killer protocol. Not a solution like the web(html/http) and email(pop/smtp) was for that other Internet, the successful one. The headlines every day just present another playful thing that add to the already high pile of transport mechanisms. When content is what matters. It’s always content my friends.
