PiCAN3 Board for the Raspberry Pi 4 adds CAN Capabilities plus a Real-Time Clock

PiCAN3 CAN Bus Board for Raspberry Pi 4 with 3A SMPS And RTC

Copperhill Technologies has recently announced the release of its PiCAN3 CAN-Bus Board for the Raspberry Pi 4. The PiCAN3 adds Controller Area Network capabilities plus a real-time clock to the new Raspberry Pi SBC. The Controller Area Network (CAN Bus) is a robust and common industrial communication bus used mostly in the automotive industry. CAN supports long travel distance, medium communication speed, and quite reliable. One of the most significant advantage with CAN-BUS is that it connects any number of ECUs (or microcontrollers) in your car through the two-wire bus, CAN High and CAN Low, reducing the weight of wires that could be gained by using point-to-point communication between ECUs. CAN bus is one of five protocols used in the on-board diagnostics (c)-II vehicle diagnostics standard. Although it is popular in the automotive industry, the Raspberry Pi doesn’t provide an off the shelf support for working with CAN-BUS. Users interested in trying out […]

Linaro Connect San Diego 2019 Schedule – IoT, AI, Optimizations, Compilers and More

Linaro has recently released the full schedule of Linaro Connect San Diego 2019 that will take place on September 23-27. Even if you can’t attend, it’s always interested to check out the schedule to find out what interesting work is done on Arm Linux, Zephyr OS, and so on. So I’ve created my own virtual schedule with some of the most relevant and interesting sessions of the five-day event. Monday, September 23 14:00 – 14:25 – SAN19-101 Thermal Governors: How to pick the right one by Keerthy Jagadeesh, Software Engineer, Texas Instruments With higher Gigahertz and multiple cores packed in a SoC the need for thermal management for Arm based SoCs gets more and more critical. Thermal governors that define the policy for thermal management play a pivotal role in ensuring thermal safety of the device. Choosing the right one ensures the device performs optimally with in the thermal budget. […]

BayLibre TPMP Lowers the Cost and Time of PVT Characterization

If you don’t quite understand the title of this post, don’t worry that’s normal! So let me explains. TPMP stands for Thermo-regulated Power Measurement Platform, and PVT (Power, Voltage, Temperature) characterization is a step in semiconductor manufacturing that involves testing wafers with various voltages, clock frequencies, and temperatures – known as Operating Performance Points (OPP) – to see how the properties of the wafer change. The equipment required to perform this characterization is usually very expensive, and the process takes time. So BayLibre was tasked by one of their customers to automate the process, and find a lower cost solution. That’s how BayLibre TPMP came to life. The TPMP is comprised of six main hardware components in order to measure NXP i.MX8 processor die-temperature: Peltier element Meerstetter TEC-1091 Peltier controller Fan Heatsink temperature sensor Chip external temperature sensor LCD display to monitor temperature, voltage, and current. The TEC-1091 chip controls […]

LEGO Minifigure shaped Mini SAM M4 Board Supports CircuitPython and Arduino

If you are a fan of the Lego movie. Perhaps you have always wanted to use Lego bricks to make something innovative and techy. Then the Mini SAM M4 board is here for you, as it is a LEGO minifigure-sized development board. Additionally, the design and layout of the board is based around the classic 1980’s ‘spaceman’, and is made by Ben Shockley. Although the board is very small, it has a lot of wonderful features. It comes with an analog reference decoupling/filtering capacitors. Also, it has an analog to digital ferrite bead, as well as a debounce circuitry for the reset and user buttons. Furthermore, the board’s software and firmware can be developed using CircuitPython or Arduino. The development board is either based on the Microchip SAMD51G 48-Pin 32-Bit ARM – Cortex M4F MCU (Mini SAM M4), or features the Microchip SAMD21G 48-Pin 32-Bit ARM Cortex -M0+ MCU running […]

DJI Launches RoboMaster S1 Education Robot

DJI is one of the world’s leading technology companies. They specialize in the manufacturing of high-end drones and other innovative and creative techs. Recently they announced the launch of their new product, Robomaster S1 education robot. The game-changing educational robot uses innovative hands-on learning, this makes it fun and smart. Furthermore, the new S1, which is a lot different from what DJI makes, is packed with a lot of features. This educational robot allows users to learn and understand science, math, physics, programming, and more. Although the official selling price of the S1 is $499, most resellers are expecting to sell it at a higher price. Resellers will sell it at about $699, which is a big difference from the official price. When CNX Software spoke to one of the resellers, they mentioned the reason for the high price, stating that “suppliers did not provide the RoboMaster S1’s cost” so […]

Eclipse IoT Survey Report Reveals Arm & Linux Dominate, Security Concerns

The Eclipse IoT Working Group has just released a report asking the global IoT developer community to share their perceptions, requirements, and priorities. And with over 1,700 individuals taking the survey between February and March 2019, the key findings are interesting: IoT drives real-world, commercial outcomes today. 65% of respondents are currently working on IoT projects professionally or will be in the next 18 months. IoT developers mostly use C, C++, Java, JavaScript, and Python AWS, Azure, and GCP are the leading IoT cloud platforms Top three industry focus areas remain the same as last year: IoT Platforms, Home Automation, and Industrial Automation / IIoT. MQTT remains the dominant IoT communication protocol leveraged by developers The Eclipse Desktop IDE is the leading IDE for building IoT applications The last point may be slightly biased because the survey was done by the Eclipse IoT Working Group, so most respondents were already […]
