Middleware – crypto

Often-seen acronyms

Symmetric ciphering

Ciphering method that ensures the reuse of a unique key, both for encryption and decryption. Example: AES, DES, 3DES, ARC4, …

Asymmetric ciphering

Ciphering method based on pair of key, a private and a public one. This also brings some kind of authentication: only the owner of private key can

decrypt content that was encrypted with a public one. And people able to decrypt with public key can be sure it was encrypted by owner of private key.

Example: ECDSA, RSA, …

Hashing

Method to calculate a unique value for a given data content. This allows ensuring a content was not modified for instance. Example: MD5, SHA, …

Cryptology helps users ensure the security of data or authentication. This
is a key element in ensuring the integrity of IoT applications for instance.

A bootloader aims to enable firmware update in the field through a communication
interface.

STM32 devices embed a built-in bootloader in system memory, supporting UART,

SPI, I2C, CAN, USB interfaces.
Alternatively, developers can implement their own bootloader in user flash memory

(also called In-Application Programming)

ST also proposes a reference code for Secure Boot and Secure Firmware Update

• TCP and IP were developed by a US Department of Defense research project to
connect a number of different networks designed by different vendors into a

network of networks (the Internet).

• It was initially successful because it delivered a few basic services that everyone
needs (file transfer, electronic mail, remote logon) across a very large number of
client and server systems and is now widely deployed.

Middleware – TCP/IP (1/2)

39

Middleware – TCP/IP (2/2)

Often-seen acronyms

ARP

Address resolution protocol: Provides

physical address from IP address

IP

Internet protocol: Primary protocol in Internet Protocol Suite.

2 flavors: IPv4 and IPv6. IPv4 will disappear as it only supports up to 232addresses, not enough for future needs, while IPv6

supports 2

128

6LoWPAN

IPv6 over low

-power wireless personal area networks: Provides IPv6 connectivity to low-rate wireless networks

IPSec

Internet protocol security: Secured version of IP, using cryptography

TCP

Transmission control protocol: Provides reliable, ordered delivery of a stream of bytes

UDP

User datagram protocol: Provides unreliable service.

Datagrams may arrive in any order, duplicated, or may be missing. Used for time-sensitive applications, when data drop is better than

delay

DHCP

Dynamic host configuration protocol: Provides means to allocate

IP address dynamically

DNS

Domain name system: Translates domain names meaningful to humans into numerical IP

ones

FTP

File transfer protocol: Provides means to copy files from one host to another

TFTP

Trivial file transfer protocol: Similar to FTP, but based on UDP, and

simpler (for example, no directory)

SMTP

Simple mail transfer protocol: Used to send e

-mail to a server

POP

Post office protocol: Used to retrieve e

-mail from a server

HTTP

Hypertext transfer protocol: Used by web browsers

SSL/TLS

Transport layer security: Secured container for application protocols using cryptography. Example: HTTPS means HTTP over SSL,

FTPS, etc.. IPSec applies cryptography at a lower level

than SSL/TLS, making it more universal. However, SSL is widely used.

Graphical user interface

bpp

Bits per pixel (also known as color depth: Number of bits used to represent the color of a single pixel in an image.
1 bpp corresponds to monochrome images.

Palette

Technique to lower image memory size by storing the set of colors used in a table and using this table for each pixel

JPEG

Commonly used method of lossy compression for digital image. The degree of compression can be adjusted, allowing a trade-off between storage
size and image quality. JPEG typically achieves 10:1 compression with little perceptible loss in image quality.

RGB / ARGB

Color model in which red, green and blue are merged to reproduce a broad array of colors. “A” field in ARGB format handles transparency
information.

Widgets

Element of a graphical user interface that can be changed by the user (such as text box, radio button)

.

ST’s MCUs can drive displays through serial or parallel interfaces

Middleware – touch sensing

Often-seen acronyms

Surface capacitance

The capacitance of a single ended electrode is modified when the finger gets close to it.

Projected capacitance

The capacitance between two sensing electrodes is modified when the finger gets close to them.

RC acquisition

Resistor-capacitor acquisition for surface capacitanceonly. It consists in measuring the charge and discharge time duration of a RC
cell made of the electrode capacitance and a load resistor.

CT acquisition

Charge transfer acquisition for surface capacitance only. It consists in measuring the duration for charging the electrode capacitance
and transferring part of the accumulated charge into a sampling capacitor. The CT acquisition is more robust than the RC one.

Capacitive touch sensing is an electrical cost-efficient technology, replacing
conventional mechanical switches to detect user actions, to build modern GUI look
and feel.

Application field – building automation and control

Building automation is the automatic centralized control of a building's heating, ventilation and air

conditioning, lighting and other systems through a building management system or building
automation system (BAS). A building controlled by a BAS is often referred to as a smart building or a
smart home.

Often-seen acronyms

BACnet

communications protocol for Building Automation and Control (BAC) networks that leverage the ASHRAE, ANSI, and ISO 16484-5 standard protocol. BACnet was designed to allow
communication of building automation and control systems for applications such as heating, ventilating, and air-conditioning control (HVAC), lighting control, access control, and fire
detection systems and their associated equipment. The BACnet protocol provides mechanisms for computerized building automation devices to exchange information, regardless of
the particular building service they perform.

DALI

Digital Addressable Lighting Interface (DALI) is a trademark for network-based systems that control lighting in building automation. The underlying technology was established by a
consortium of lighting equipment manufacturers as a successor for 0-10 V lighting control systems, and as an open standard alternative to Digital Signal Interface (DSI), on which it is
based. DALI is specified by technical standards IEC 62386 and IEC 60929. Standards conformance ensures that equipment from different manufacturers will interoperate. The DALI
trademark is allowed on devices that comply with the current standards when manufactured.

DLMS / COSEM

IEC 62056 is a set of standards for Electricity metering data exchange by International Electrotechnical Commission. The IEC 62056 standards are the International Standard
versions of the DLMS/COSEM specification. DLMS or Device Language Message Specification (originally Distribution Line Message Specification[1]), is the suite of standards
developed and maintained by the DLMS User Association and has been adopted by the IEC TC13 WG14 into the IEC 62056 series of sta

ndards. COSEM or Companion Specification

for Energy Metering, includes a set of specifications that defines the Transport and Application Layers of the DLMS protocol

DMX-512

DMX512 (Digital Multiplex) is a standard for digital communication networks that are commonly used to control stage lighting and effects. It was originally intended as a standardized
method for controlling light dimmers, which, prior to DMX512, had employed various incompatible proprietary protocols. It soon became the primary method for linking controllers
(such as a lighting console) to dimmers and special effects devices such as fog machines and intelligent lights

KNX

KNX is a standardized (EN 50090, ISO/IEC 14543), OSI-based network communications protocol for building automation. KNX is the successor to, and convergence of, three
previous standards: the European Home Systems Protocol (EHS), BatiBUS, and the European Installation Bus (EIB or Instabus)

• Control your 3-phase motor with top performance

• STM32 microcontrollers offer the performance of the industry-standard Arm® Cortex®-M cores running either Vector control or

FOC modes, widely used in high-performance drives for air conditioning, home appliances, drones, building and industrial
automation, medical and e-bike applications. STM32 MC SDK (motor control software development kit) firmware (X-CUBE­MCSDK and X-CUBE-MCSDK-FUL) includes the Permanent-magnet synchronous motor (PMSM) firmware library (FOC control)
and the STM32 Motor Control Workbench (to configure the FOC firmware library parameters), with its graphical user interface
(GUI). STM32 Motor Control Workbench is PC software that reduces the design effort and time needed for the STM32 PMSM
FOC firmware configuration. The user generates a project file through the GUI and initializes the library according to the
application needs. Some of the variables of the algorithm being used can be monitored and changed in real time.

Application field – motor control

Often-seen acronyms

BLDC Brushless DC: permanent magnet motor with trapezoidal shaped B-EMF, FOC applicable
PMSM Permanent magnet synchronous motor: with sinusoidal shaped B-EMF, FOC applicable
ACIM AC induction motor: type of motor, FOC applicable
FOC Field-oriented control: Mathematical technique used to achieve decoupled control of the flux and torque in a 3-phase motor.

HFI, MTPA

High Frequency Injection: algorithm for very low speed and fast acceleration (air con, fridge) and increased efficiency for low- or zero-speed, full
torque applications (washing machines, factory automation)

• “Maximum Torque Per Ampere” (MTPA): optimizes the motor torque for each load and increases the efficiency,

• “Feed Forward”: improves the current control at high speed.
