Dev Tools Extend Transportation Safety Standards Coverage

IAR Systems has updated the functional safety editions of the leading embedded development toolchain IAR Embedded Workbench with new functional safety certificates. The new certificates add the standard EN 50657:2017 “Railways Applications – Rolling stock applications – Software on Board Rolling Stock” as well as a later revision of the “Road vehicles – Functional safety” standard called ISO 26262:2018.

Functional safety is one of the most important features in many embedded systems and companies must consider development tools as an integral part of the system certification, says IAR Systems. The proof of compliance for the tools increases cost and time of development. To solve this problem, IAR Systems provides certified versions of the complete compiler and debugger toolchain IAR Embedded Workbench for Arm, Renesas RX, Renesas RL78 and Renesas RH850.

The build chains of IAR Embedded Workbench for Arm, RX, RL78 and RH850 have been tested and approved according to the requirements on support tools put forth in the international umbrella standard for functional safety IEC 61508, the standard for automotive safety-related systems ISO 26262, and the the European railway standard EN 50128 and EN 50657. For Arm, RX and RL78, the certification also covers IEC 62304, defining the life cycle requirements for medical device software.

The quality assurance measures applied by IAR Systems and the included Safety Manual allow application developers to use the tools in safety-related software development for each Safety Integrity Level (SIL) according to IEC 61508 and each Automotive Safety Integrity Level (ASIL) of ISO 26262. IAR Embedded Workbench is certified by TÜV SÜD.

IAR Embedded Workbench provides a complete IDE including the IAR C/C++ Compiler and the C-SPY Debugger. The code analysis tools C-RUN® and C-STAT® add static and runtime analysis, enabling complete code control through the entire development cycle. Thanks to the complete integration of the tools in the IAR Embedded Workbench IDE, developers get up and running quickly with the analysis.

IAR Systems also offers a Functional Safety Support and Update Agreement with guaranteed support for the sold version for the longevity of the contract. In addition to prioritized technical support, the agreement includes access to validated service packs and regular reports of known deviations and problems.

TECHNOLOGY FOR THE INTERNET-OF-THINGS

IoT: From Device to Gateway
The Internet of Things (IoT) is one of the most dynamic areas of embedded systems design today. This feature focuses on the technologies and products from edge IoT devices up to IoT gateways. Circuit Cellar Chief Editor Jeff Child examines the wireless technologies, sensors, edge devices and IoT gateway technologies at the center of this phenomenon.

Texting and IoT Embedded Devices
Texting has become a huge part of our daily lives. But can texting be leveraged for use in IoT Wi-Fi devices? Jeff Bachiochi lays the groundwork for describing a project that will involve texting. In this part, he gets into out the details for getting started with a look at Espressif System’s ESP8266EX SoC.

Exploring the ESP32’s Peripheral Blocks
What makes an embedded processor suitable as an IoT or home control device? Wi-Fi support is just part of the picture. Brian Millier has done some Wi-Fi projects using the ESP32, so here he shares his insights about the peripherals on the ESP32 and why they’re so powerful.

MICROCONTROLLERS HERE, THERE & EVERYWHERE

Designing a Home Cleaning Robot (Part 4)
In this final part of his four-part article series about building a home cleaning robot, Nishant Mittal discusses the firmware part of the system and gets into the system’s actual operation. The robot is based on Cypress Semiconductor’s PSoC microcontroller.

Apartment Entry System Uses PIC32
Learn how a Cornell undergraduate built a system that enables an apartment resident to enter when keys are lost or to grant access to a guest when there’s no one home. The system consists of a microphone connected to a Microchip PIC32 MCU that controls a push solenoid to actuate the unlock button.

Posture Corrector Leverages Bluetooth
Learn how these Cornell students built a posture corrector that helps remind you to sit up straight. Using vibration and visual cues, this wearable device is paired with a phone app and makes use of Bluetooth and Microchip PIC32 technology.

INTERACTING WITH THE ANALOG WORLD

Product Focus: ADCs and DACs
Makers of analog ICs are constantly evolving their DAC and ADC chips pushing the barriers of resolution and speeds. This new Product Focus section updates readers on this technology and provides a product album of representative ADC and DAC products.

Stepper Motor Waveforms
Using inexpensive microcontrollers, motor drivers, stepper motors and other hardware, columnist Ed Nisley built himself a Computer Numeric Control (CNC) machines. In this article Ed examines how the CNC’s stepper motors perform, then pushes one well beyond its normal limits.

Measuring Acceleration
Sensors are a fundamental part of what make smart machines smart. And accelerometers are one of the most important of these. In this article, George Novacek examines the principles behind accelerometers and how the technology works.

SOFTWARE TOOLS AND PROTOTYPING

Trace and Code Coverage Tools
Today it’s not uncommon for embedded devices to have millions of lines of software code. Trace and code coverage tools have kept pace with these demands making it easier for embedded developers to analyze, debug and verify complex embedded software. Circuit Cellar Chief Editor Jeff Child explores the latest technology trends and product developments in trace and code coverage tools.

Manual Pick-n-Place Assembly Helper
Prototyping embedded systems is an important part of the development cycle. In this article, Colin O’Flynn presents an open-source tool that helps you assemble prototype devices by making the placement process even easier.
