TI AM64x 7-core processor is made for PLC’s, motor drives, industrial robots

AM64x GP EVM development platform

Texas Instruments AM64x is a family of 64-bit Arm processors with functional safety designed for Programmable Logic Controllers (PLC), motor drives, remote I/O, and industrial robots. The top-end processor of the family, AM6442, comes with seven cores including two Cortex-A53 application cores, four Cortex-R5F real-time cores, and one Cortex-M4F isolated core. AFAICT, while the documentation is dated January 2021 and TI announced the processor in February in a blog post with a cryptic title, it was only first picked up by Embedded Computing in early May. Besides the processor itself, TI also provides an AM64x starter kit and a full-featured AM64x evaluation kit, and several companies are already preparing development boards and modules as we’ll see further below. TI AM64x processor AM64x key features & specifications: CPU cores Dual-core Arm  Cortex-A53 processor @  1.0 GHz with 256KB L2 shared cache with SECDED ECC, 32KB L1 D-cache, 32KB L1 I-cache Up […]

3D printer board leverages Allwinner A64’s AR100 core for real-time control

Recore Allwinner A64 3D printer board

Elias Bakken has been working on Recore 3D printer control board based on Allwinner A64 processor since 2019 and with revision “A5” of the PCB,  Recore is now considered stable and will ship to customers. But wait? Isn’t Allwinner A64 just a quad-core Cortex-A53 processor meant to run Linux? But 3D printer control boards require real-time I/O and that’s why many are designed with STM32, Arduino compatible Microchip MCU or other microcontrollers. The trick here is that Elias did not use the Cortex-A53 cores for real-time control, but instead the 300 MHz AR100 32-bit OpenRISC 1000 core found in Allwinner A64 SoC. Recore specifications: SoC – Allwinner A64 quad-core Cortex-A53 processor running at 1 GHz, with AR100 32-bit core @ 300 MHz, Mali-400MP2 GPU System Memory – 1 GB DDR3 RAM Storage – 8 GB eMMC flash Video Output – HDMI output to connect a display Networking – Gigabit Ethernet […]

New STMicro STM32G4 MCUs target cost-effective motor control systems with up to 512KB flash

NUCLEO-G491RE board

STMicro introduced the STM32G4 family of mixed-signal microcontrollers in May 2019 for e-mobility (e.g. e-bikes), digital power supplies, advanced motor controls, lighting, and building-automation products. The Arm Cortex-M4 based microcontrollers clock up to 170 MHz, and include new hardware mathematical accelerators to boost processing of applications using Cordic (Coordinate Rotation Digital Computer) and Filtering functions to support increased performance and energy efficiency. This enables faster and more efficient calculations for energy-saving motor controls and frees up the core to receive more sensor data and control additional user functions. The STM32G4 Series of mixed-signal microcontrollers have three lines of products: The STM32G4x1 Access line – general-purpose microcontrollers with an entry-level set of analog peripherals The STM32G4x3 Performance line – general-purpose microcontrollers with the maximum number of analog peripherals The STM32G4x4 Hi-resolution line with high-resolution timer and complex waveform builder plus event handler (HRTIM) for digital power conversion, such as digital switched-mode […]

$50 Fish32 Seed “Education” ESP32 Board Comes with Plenty of I/Os, Sensors, and Connectivity Options

ESP32 Fish32 Seed Board

Sometimes I feel the word “Education” is sometimes thrown around for marketing purpose, and AnalogLamb Fish32 Seed board for “ESP32 Community Education Board” feels that way to me as so far, I could not see any tutorials or other teaching/ learning resources for the board. Having said that I can see why it could be potentially used for education: the sheer number of features, sensors, and connectivity options should allow students to learn to program my different components around ESP32. It’s just at this stage it may not be such an easy platform to learn on. Fish32 Seed board specifications: Supported ESP32 Modules – ESP32-WROVER, ALB32-WROVER, ESP32-WROOM-32 Connectivity 802.11 b/g/n WiFi and Bluetooth 4.2 via ESP32 10/100M Ethernet (RJ45) via WIZnet W5500 chip with support for up to 8 independent sockets LoRa via SX1278 chip (433 MHz) Sensors NXP MPU-9250 with 3-axis MEMS gyroscope, 3-axis MEMS accelerometer, 3-axis MEMS magnetometer […]

EduExo DIY Robotic Exoskeleton Kit is Arduino Powered, 3D Printable, Designed for STEM Education (Crowdfunding)

Robotic exoskeletons are used for medical purposes such as helping with the rehabilitation of stroke patients, or enable paraplegics to walk again, as well as in the work place to assist people lifting heavy objects. While it’s possible to learn about the theory about exoskeleton technology, practical experience may help grasping all concepts better. However, there are not many courses available, and exoskeletons are usually expensive, so Volker Bartenbach, PhD at ETH in Zürich, has decided to created EduExo robotic exoskeleton kit for education purpose. The EduExo hardware is based on off-the-shelf components like an Arduino UNO board, a motor, and a force sensor, as well as a rigid exoskeleton structure and cuff interfaces. The latter is optional as you can get the kit without it, and will instead receive the STL files to 3D print the parts yourself. There’s also a handbook to help you get started in several […]
