Telemaco3 : Driving Car Security Into the 21st Century

Cars are undeniably getting smarter, but few people understand why, and even fewer have a grasp on how to make them smarter as ST does.
This is because ST has been developing telematics solutions for years, long before anyone talked about autonomous driving or smart vehicles.
In keeping with that trend, ST released Telemaco3, a new family of single-chip telematics processors.
However, before one can fully grasp the power and engineering that went into these new chips, we must first understand what telematics is.

Telematics is a compound word combining “telecommunications” and “infomatics”, the science of information systems.
Hence, according to its strictly academic definition, telematics is the science of sending, receiving and storing information using a telecommunication standard.
First coined in France in 1978, the word mostly refers today to vehicle telematics, meaning the information is about a mode of transportation (boat, car, train, plane, etc.).
Furthermore, although this was not the case at first, telematics now always includes information from global navigation systems (such as the GPS) and increasingly implies the ability to remotely control a vehicle or influence its operation.

Big Goals Drive Euro Alliance for IoT Innovation

The Internet of Things (IoT) is on a trajectory to connect 45 billion things by 2020.
So the European Commission Alliance for Internet of Things Innovation Structurecreated the Alliance for Internet of Things Innovation (AIOTI) to develop a dynamic IoT ecosystem in Europe.
In large part, this aims to leverage the unique opportunity of new markets to invigorate Europe’s industry, address demographic changes, and transform growing cities into bustling innovation hubs.

ST is one of the 21 founding members of AIOTI.

In already completed phase 1 efforts, the alliance has already defined the reference for the new IoT Large Scale Pilots (LSP) program, which the European Commission plans to deploy this year.
One of the EU’s Horizon 2020 work programs (the European program for Research & Development), the LSP program has received $100 million in funding.
Its goal is to evaluate a set of use cases around five main projects on a large scale.
These projects–Smart Living for Aging Well; Smart Farming; Wearables; Smart Cities; and Smart Mobility–are all closely aligned with ST’s strategic interests.
As a result, the ST has made significant contributions to the set of reports published by the AIOTI that provide recommendations and guidelines related to the LSP program.

Going forward, ST has been appointed as a technology enabler for three of the projects: Smart Living
Smart Farming
Smart Mobility
ST will continue to participate and contribute to the other projects, as well.

The Alliance is organizing an important matchmaking event to be held in Brussels in mid-February. The private event requires an invitation, which can be requested here.

eDesignSuite : Interactive Simulations and Automatic Schematics

eDesignSuite support you to making an electronic product is both an art and a science.
Complex electrical engineering principles guide the designers’ choices and compromises, but putting all the pieces together is also an art that requires thoughtfulness and experience.
To help with both of these, ST offers platforms and development tools. One of them is eDesignSuite, an application that helps design and simulate a circuit based on specific components.
It allows a user to modify and experiment quickly to come up with the optimal solution. In this post, we will look at two case studies to better understand the power of eDesignSuite.

To use the application, simply create an account on my.st.com
Once logged in, go to https://my.st.com/analogsimulator/
The interface (seen above) will present you with a series of applications, because what makes this tool special is its practical aspect.
Instead of simply offering a blank canvas, eDesignSuite starts by asking what the engineer is trying to accomplish to offer relevant data and suggest components.

eDesignSuite help you also to designing NFC antenna

Remote I/O using ARM mbed + NUCLEO_L152RE + AUREL RTX-MID-3V (Sub1GHz module)

Using mbed for: Transfer the status of the Blue button (present on the ST NUCLEO boards) via wireless (Sub1GHz) using the AUREL RTX-MID-3V.
This SW was tested on NUCLEO-L152RE.
The mbed code for RX is here (remote Relay or LED), for TX is here (remote contact from, for example, a Thermostat).
Here there are the binary files (TX and RX) for NUCLEO-L152RE.


Below tere are the connections between Aurel module (RTX-MID-3V) and the MCU

ATTENTION:
This release of FW use the mBED SERIAL_TX (D1 – PA2) and SERIAL_RX (D0 – PA3), this pins are SERIAL_2 that are used (under mBED) for send/receive data via USB.
For this reason is necessary to do some modifications on NUCLEO-BOARD.
Suppose to use the NUCLEO-L152RE board is necessary to do:

  • Put a jumper on SB62 and another on SB63
  • Remove a 0 ohm resistor from SB13 and SB14

More info are here.


Below there are the I/O to use to interface the contact from thermostat (TX board) and the remote relay (RX board).

Wireless systems & IoT needs a good antennas

Introductions to the Antennas


Up to now, thanks to the grow up of the WireLess applications, is necessary know some basic concept regarding the antennas.

First: the reference antenna is the dipole (see below).

The principal dipole caracteristic is that it has gain equal to 0 (zero).
All other antennas are some meccanical trasformation of the dipole.

Second: a minimum antenna length must be λ/4.
In many application use a  λ/4 antenna is not possible and are used a ceramic antennas or a custom antennas design on pcb.
Remember that this means to lost efficiency (distance) on your wireless system.

Third: do not forget to create a good ground reference for your antenna.

Fourth: is very important match the impedance from antenna to the transceiver to avoid lost of power (SWR).
For this reason is necessary use a balun to match the impedance.

Fifth: reduce the Kbps (Kbit per second – Data Rate) means, in general, increase the S/N of your receiver.

It’s clear that each wireless system, is a compromise between the five points mentioned above.
If you don’t have experience to make antenna is strongly recommended to use an external consultant with a good antenna experiences.
Remember that antenna is your unique interface with the wireless world.


How to calculate a 1/4 wave antenna
c = light speed, that is 300,000 km/s or, in meters, 300.000.000 meters
f = frequency in Hz, and 868 MHz is equivalent to 868.000.000 Hz
λ (Greek letter lambda) = wavelength resulting at the frequency = c/f
Example:
—–f=868Mhz
—–the λ=c/f = 300000000/868000000 = 0,3456221198156682 meters
—–the 1/4 wave antenna measure: 0,3456221198156682 / 4 = 0,0864 meters -> 8,64 cm
